    Spacetime
In summary: Einstein said "Space-time is not an independent entity, but rather a feature of the gravitational field." ... He went on to say that "space-time is not a material substance, but is rather a convenient way of representing the physical situation." In summary, spacetime is a hidden object that is non-breakable and continuous and smooth. It is flexible and has no breaks. It is the "Field" (das Feld) Einstein referred to.

Yes, Kea, our privilege is enormous, and it remains to be seen if we deserve it. Why have we been shown these things? Probably just mother playing with statistics. But we are here, and we have this time to talk. Amazing.

I know hiding in the woods is not any kind of answer. Advertising the beauty and richness of wilderness may even be another step toward the destruction of what we love. Maybe John Muir, the great American naturalist, is to blame for the desecration of Yosemite and Yellowstone. This is useless thinking. The mind, as a friend constantly reminds me, is a doubting mechanism. I don't know where he got that line.

So we study and we reach across the planet looking for like minds. We have been given this incredible opportunity, perhaps the first steps toward a planetary consciousness. Joy of heart, fear of the doubting mind. Do we pursue our joy, act from the heart, or curl up and try to protect our doubts? I guess that depends on the weather.

Today the clouds have shifted and the local weatherman, a snaggle-toothed child, predicts a week of sun and warmth. God knows we need it. It has rained here nearly every day for six weeks. Maybe, now, those seeds will warm up in the mud and make it to daylight after all. I am glad I planted them instead of giving into doubt.

About six weeks ago I wrote in this forum that we do not need a dry season. It was early spring then and the snowmelt had already gone, the streams were mostly boulders in dry wash. Now the streams are high, the ditches are full, and the ground is a wet sponge. Summer is a few days away. I think we can take a deep breath and get ready for whatever comes next.

I want to know more about category theory. I am reading Penrose, The Road to Reality, altho I was initially put off by the self-assured title and subtitle, A Complete Guide To The Laws Of The Universe. Well. Anyway, this book is helping me get an idea of things Marcus and selfAdjoint and others, like yourself, talk about fluidly. Like the Riemann surface, the complex plane, inside and outside loops. I was not so favorably impressed by Penrose in his earlier book, The Emporers New Mind.

With all the goings on in string and loop, there is a lot to try to catch. And I am working on a borrowed phone line, with a rather anxious owner. But I will make another go at catagories. Onward and upward, eh?

Be well,

Richard

Oh dear, you're right about the advertising. OK. Everybody: The West Coast is a horrible, bug-infested jungle where it doesn't stop raining and it's impossible to get rid of the rot and mould.

I flicked through Penrose's book. It looked pretty good. Not wordy and obscure like the Emperor's. I see he ends up trying to explain some of the mathematics of Twistor Theory. That's ambitious, but admirable. It bugs me when politicians and academics alike underestimate the layman. Anyway, I thought the subtitle A Complete Guide To The Laws Of The Universe was hilarious. No doubt he is partly serious, but since he's on the right track that's OK. Mostly, I suspect he's having a go at the pop physics culture.

It's raining a lot here too now, which is seasonal. The exotic trees have shed their leaves, and there is a light snow cover on the foothills which I can see in the distance from the Physics building even though this town is smoggy in winter because most people burn wood for warmth.

Well, it would be nice if there were such a point, at least a unique one. But as it happens it appears that everything is moving away from everywhere.
If the Universe is expanding at an accelerating rate then it would appear 'that everything is moving away from everywhere' and this phenomena would be evidence for a single point of origin, surely?

Hi Daminc

It is a hotly debated topic. The point of origin you seem to be inferring is often called a singularity. Singularities are fairly common in math, but not seen in physics. We have ample evidence of something going on at the center of many galaxies, called a black hole, and it seems to be something like a mathematical singularity, but we can't see them directly. Stephan Hawking is probably the most prodigious popular authority on this question. He recently reversed himself on one of his major findings, the question of whethor any information going into a singularity can ever come out again. Currently, if I understand correctly, he thinks some information might be able to get through.

Anyway I think the important thing for you is to keep working your imagination, and don't get stuck or overly attached to any "fact", or opinion or idea for that matter. You have been thinking rather deeply about space and have apparently begun to think about time as well.

Lets take a look at what you have so far. Hubble (and countless later astronomers) tell us that the universe is expanding in all directions. If we run the process in reverse, and look (with our imaginations) back in time, we expect that the universe should have begun in some region. Curiously, if we do this with the observables and the maths, we find that the universe started right here.

There is still the question of where, exactly, right here is. Does "right here" mean here in The Milkyway Galaxy? Or does it mean right here in our arm of the spirol? Or does it mean right in our own solar system? Right here on Earth? Right here in Hubble's eyeball? Which cell in the retina?

Singularities are far smaller than eyeballs. You see, if the singularity were the size of Hubble's eyeball, there would be plenty of room for all kinds of information to get through. Some of the infalling stuff would miss some of the other infalling stuff and so would go raceing outward again. That is not a singularity. If all the infalling stuff goes to a single point, nothing can come back out again. It all cancels.

So maybe the singularity is more than one point, maybe it is two or three or some small countable collection of points. Then the infall might cancel out almost everything, but something might still slip through the middle and come out...where? In another Universe? But if there is another universe, then there is more than one universe, so they are not universes at all, since the universe by definition is only one thing. Sadly, this line of thought reduces to the absurdity of semantics

Things get worse when you add time as a dimension. If the singularity is the first instant of the universe, what came before that?

Consider Euclid's fifth postulate, regarding the existence of parallel lines. If the universe begins in or ends in a singularity, then all lines must converge there, so no lines are parallel and Euclid's fifth is false. Ouch. There is a whole mathematics built on that presumption.

I am still trying to figure all this out myself. Euclid is responsible for most of our ideas of ordinary local space. But there are other ideas. There is deSitter space and anti-deSitter space. Robinson_Walker space (I don't know what that is but I saw it written somewhere IIRC) Riemann space and Minkowski-Einstein space. Each of these variations has some small difference that turns the others upside down, inside out, or frontward for backward or something. You can try to keep all the names straight if you like, I am not good at that.

Then string theory comes along to add a bunch of hidden dimensions. Yikes.

I suspect that the answer in the end will be overwhelmingly simple. Probably 42 or 43 or some modulus added to one of those. Even Penrose pokes fun at himself with his subtitle. Douglas Adams is more fun to read and IMHO may have a better grasp on Reality. But then, Penrose may be a fan of old Bing Crosby Bob Hope movies, I don't know.

My advice is that you should enjoy the summer. Ponder the singularity at the heart of a violet while lying on your stomach in the grass, and don't forget to breathe. We are tiny creatures in an immense Universe.

Be well,

Richard

Hi Kea

Most city people here burn gas or oil for heat, because they can and because they don't like sweeping up sawdust, ash, woodchips, and the occasional long-horned wood beetle. My country friends mostly burn wood for heat, with gas for backup. We are proud anachronists. Even so, Duluth had two or three smog alert days last year. Due to a thermal inversion along a stationary front or something, not, as far as I know, due to our campfires and woodstoves.

I can see how a city full of woodstoves could create a kind of smog, especially in mountian valleys where thermal inversions are common. Denver has that problem. I think they even ban woodfires from time to time. Los Angeles, a city famous for smog, mostly from automobile exhaust, is actually pretty clean these days, but for my taste, the air has a slightly burnt, overly used quality, even on a fair day. But once you have tasted and learned to appreciate the highly oxegenated vapours rising off a clean wetland, you are spoiled forever. Most Angelenos don't know that the clouds are not supposed to be orange at midday, and they think, rightly so in their locality, that wetlands stink. Even so, southern California is much cleaner than it used to be. Environmentalists can make a difference.

Maybe I should start a business selling pressurized bottles of cool, clean woodland air. I have a feeling it will be big, someday. I hear they are already selling shots of oxygen to people on the streets in Biejing, Tokyo, and Mexico City.

Thank you for the word images, Kea.

Be well,

Richard

I can't stop thinking...

Why doesn't nature have straight lines?
Why do electrons conform to 2, 8, 8 valencies. Why not 2, 4, 8 etc or even 3, 6, 9 ...
Do electrons leave a wake as they circle the nucleus.
why did the fundememntal particles form?
Why/how did they join to create protons and neutrons etc
Why do creatures with a heartbeat have a similar number of heartbeats before they die?
There must be a viable alternative to singularities because infinities has no place in nature.

I have these, and many more questions running through my brain a lot of the time with no ability to answer them. My friend has expressed his concern that continualy thinking about stuff that I can neither prove or disprove is a waste of my time. The result is effecting my sleep patterns because I find it hard to switch my brain of so I've thought hard on why I do this and I've come to a possible conclusion...

I'm searching for a moment of clarity.

I wonder if everyone is like this in one degree or another.

We search for some meaning or other to clear the confusion we live with all our lives. Some people use religion, others use science, some even use art in varing degrees in order to try and find that spark of clarity.

Are we better of just not knowing and just be content to be alive? What drives us to know the unknowable?

Some people may go through life not even wondering where the food they
eat comes from, but most must wonder from time to time about their existence.
I think a beautiful explanation for the universe is possible, and that one day
all the paradoxes thrown up in mainstream science will be solved.
A new dawn may not be far away, and the people of the future may look
back and laugh at our attempts to explain the universe, as we do today
about the flat Earth believers.

Hi Wolram and Damink

My sympathies are with those who face the existential void with courage. The void does not return anything for our questions, but if you stare at it long enough, it takes on its own kind of beauty. Even meaning. I think the truth is in the paradox...not in any particular, one-sided solution, but in the fact of the paradox itself. We see things two ways. The two ways are both internally consistant, but they confict. Why are we so certain there can be only one truth? What do we lose, if we accept that there can be two conflicting answers?

Flat or curve? Field or particle? Infinite or bounded, open or closed?

There is a story (Taoist I think?) of a monk who was chased by tigers. He fell over a cliff and caught his fall on some thin vegetation. The roots were giving way, too weak to hold him long. Looking down, he saw more tigers waiting for him below. There was a berry ripe on the twig between his fingers. He tasted it. It was delicious!

Individual life is very short, often painful. But our cultural life goes on beyond our individual life. Beyond that, there is the very peculiar, perhaps even singular (my dear Watson!) condition of being human. And beyond that there is life itself. In what way is it better for the individual to reign in hell rather than serve the common interests of life, humanity, and culture? And it looks to me like only one monster gets to reign in hell, the rest are mere deluded servants of misery. In what way is it better to be a servant of misery than a servant of joy?

No answers. Better questions?

be well,

Richard

Hi Nightcleaner
Your writings remind me of Captain ahab and his manic search for moby dick.
I guess some subjects can get to deep, and with few if any facts to resolve
them, can seem paradoxical, but we should not be captain ahabs, rather i think
we should take time of from our main quest and tour other domains, ahab may
have lived a better life if he could have relinquished his chase of MD.
Our universe seems like an almost empty void with the odd flicker of EMR for
us to ponder, but that is not to say that nothing else exists and that one day
we may find it.
To me our U is a hall of mirrors, that fools us into chasing our tails to catch
the original image, given time we will catch it.

Hi Wolram

Thanks! How does that go again? "Call me Ishmael," I think. Well, maybe I am in a manic mood today. The sky here is perfectly clear and the temperature is perfectly seventy two degrees, with a light breeze off the lake. I just have to get outside. There is gravel to shovel and a stubborn rusted nut on my bumper ball hitch to pound on. I made a dent in it yesterday and another hour or so of hammering might break it free today. Such are my hopes.

Herman Melville. A Yank author, I believe?

Well, hammering the nut is another obsessive pastime. I know perfectly well that the mechanic at the garage could twist that thing off of there in a minute, and he probably wouldn't charge me anything either. I am a regular customer. Gravel roads and mud ruts are hard on vehicles. Why do I do it? Why do I yell and curse when I hit my hand instead of the chisel? And the noise hurts my ears. I could wear earplugs but I don't. Obsessive compulsive and self-destructive, too, on top of mania. I should probably be better off today just going back to bed.

Oh well, one has to do something. And if I break that nut I will have the satisfaction that I have once again overcome the vagauries of bad design, poor maintenance, and lack of planning. Why do people run marathons? Some people even die doing it. I guess it is ok if you really like to run. I hate running, and no one expects me to do it anymore since I broke my leg. But what if you really hate running, but you are really good at it, and it is fun to win? I'll keep that in mind when I next bust my knuckles on cold steel. That nut is coming off of there and I will not be delayed by pipe smoking onlookers. Maybe I'll have a good laugh about it later this afternoon as the surgeon sews my fingers back on my hand. Ha. Ha ha. I knew that was going to happen.

Well ok, I have convinced myself to go to the mechanic instead of taking a chance on hospitals. I hate hospitals. I really hate hospitals. I could get a good job in a hospital. Grrrr. If I keep on like this, I may end up filling out applications as well as surrendering to a mechanic! You and your Ahab, what have you done?

Be well (it is the only way I know to avoid hospitals)

Richard.

Well i have fixed the economy seven whatsathingamajig, its a device that allows ofpeak electricity at a cheaper rate, I have took benji my wolf hound
cross red setter his five mile walk, and now my ankle hurts, to many nuts and
bolts and pins, so you can guess i hate hospitals, its about 90c in the midlands
with high humidity, something i am not used to, and every frigging neighbor
is diy ing, the noise is horrendous, so i have fetched myself a rum and coke
turned the music up and am going to close my mind to the world.

Yes, I am sure you are right. I don't have one, but I have about thirty kinds of chisels and a huge assortment of hammers. Where does all this stuff come from?

The nut is still, as of this writing, firmly in place. The dent is quite a bit larger, however, and I still have all my fingers. No hospital visits. I spent another hour hammering yesterday. An hour of that is about all I can stand.

I did go to the mechanic, but he was very busy. I didn't even get a chance to talk to him. We have a marathon starting in town this morning and the restaurants, hotels, and shops are crowded. Good for business. Bad for locals trying to start work on projects that have been sitting around all winter.

The good news: I drove up to my cabin to do the pounding. No use spoiling anyone elses day with loud repetitious noises. The mosquitoes were tolerable, but it is inadvisable to swat one on your forehead when you have a hammer in your hand. On the way up, I stopped by a slough full of wild iris. They are really beautiful, blue with yellow interior, and grow only in standing, clean water. There also were plenty of scouring rushes, a primitive plant with silica in the cell walls, used by campers to remove campfire carbon from their mess kits. And of course cattails and water lilies, and I think I saw arrowhead, a plant with an edible potato-like tuber and heart-shaped leaves that grow above the water, not on the water as lilies do. I always enjoy the blooming of the wild iris, because the colors are so rich and pure to the attentive eye.

There were some kind of large grasses growing there also, and they had flower heads still wrapped inside of leaves. I like to eat the tender shoots of grasses, and was tempted to try the flower heads also. They had a little soft center that tasted like fresh corn on the cob, but the little prickles on the florets made the back of my mouth itch. I guess I won't try them again. I was hoping for the flower spikes of cattails, a delicious treat, but they aren't ready yet. You can eat the roots and shoots of cattails also, very mild and tasty, but the one I picked was full of ants feasting on the rich sweet sticky sap. I have not gotten into eating ants yet, and their feverish excitement at being disturbed spoiled my taste for cattail shoots.

Cattails, horsetails (scouring rushes), wild iris, and arrowroot are all signs of clean water. They are known indicator species, and I am very glad to live where they grow.

I have taken this thread far from where it started, with Pel's interest in Space-Time. Sorry Pel. It is hard to think about space-time when the days are so long and sweet. Is spacetime a thing in itself? I don't know. The utility of Planck's action potential led me to think so for a while, but selfAdjoint and others keep insisting on background independence. I wish I had something to add here, other than botany.

The only thing I do have is that idea with which I started on Physics Forums, which is that the action potential can be taken to comprise a spherical analog in 4d, which then seems (to me) to imply an isomatrical structure to spacetime. Who knows? If I can get the maths right, it may prove useful after all. Meantime it keeps me trying to get the maths right, so provides me with motivation. What else does a spacetime theorist need?

Be well,

Richard

The joys of nature, but it is amazing how much edible food stuff we pass by,
my gran used to make nettle soup, though i can't remember the taste, black
berry pie, delicious, wild mushrooms can not be beaten for taste, puff balls
aren't bad but not nice, dandelion roots are edible but I am not keen, the leaf
makes a potent brew, the recipe known only to the older generation, those
tender sweet grass shoots, the ones that slide from the main stem when pulled, are what i chew on when dog walking.

Hi Wolram
I was just reading somewhere about people in Mexico eating insects. Some people are willing to pay $40.00 U.S. for a plate of a dozen roasted Maguay worms, the kind of larvae found at the bottom of some kinds of Tequila. Worms and beetles are also eaten, as well as ants, locusts, grasshoppers.

I remember seeing a Nature program about a lake in Africa where a kind of fly hatch sends thick clouds of them into the air above the lake. The villiagers catch them in muslin nets and crush them into a thick paste which they make into cakes. A boy of about seven was shown eating such a cake with evident enthusiasm.

I was wondering about your outside loo. Most people here have indoor plumbing, and either live in town where the toilets flush into a sewer which takes the effluent to a treatment plant, or in the country where the common practice is to run the waste into a large septic container buried deep in the ground, or covered over with a mound of gravel topped with dirt and grass. My friends use the old fashioned outhouse, which is a hole dug in the ground with a small wooden building perched over.

When the septic gets full, you call for a pump truck to come suck it out. This is usually an odiferous process, but only has to be done maybe once a year, or even less often. When an outhouse hole gets full, you have two options. Either move the outhouse to a new hole and cover the old one up, or dig the stuff out of there and compost it for use as fertilizer on trees and shrubs.

There are also other options, such as a biolet which is designed for composting so you don't have to do all that unpleasent digging, and some people even have systems that lead to their own incinerator. No fuss there, but rather spendy. As a biologist, I prefer methods that involve composting, but am rather horrified at what sometimes takes place. You definitely do not want to get on the wrong end of that shovel. And most people seem to have no idea of vectors, that is insects and other small creatures that are fond of our product, and also fond of flying into the kitchen to crawl about on plates and fruit bowls. I havn't had much luck telling people they need to keep their compost piles tightly covered.

So my question is, what happens when the outside loo gets full? Or, is it connected to a sewer? In terms of space and time, of course.

Thanks,

Richard

Hi nightcleaner,
You are taking me back to my youth, when staying at grandads house ,a
two up two down cottage ,with no indoor plumbing, if you couldn't wait till
morning, one had to take a torch and go the " out house", little more than
a shed, full of creepie crawlies, I forget how often the," Night soil man", came
to empty the bucket, i was only eight to twelve years old, but it dint arf wiff.
Grandad always encouraged us lads to pee outside around his vegies, to keep
the rabbits away, "he had a huge garden", with black current , goose berry
bushes, apple and pear trees, you name it he grew it.
He worked at the cement quarry, a mile up the road from where i live, looking
after all the equipment, i think he was the first man, around here anyway to
splice steel ropes. the quarry is closed down now, and is scheduled for development.
Our out side loo is connected to the main sewer, the council houses around
here were built with two loos one inside other out.
By the by the temp reach 95f here today, we had to stop work at mid day
as our cream room couldn't be kept at 10c, the cooling units not being able
to cope, the factory makes fresh potted desserts.
I have always fancied trying one of them whitchity? grubs, found in oz, they
look tasty, i will try anything, "once".
all the best good bud.

Hi wolram

We have witchetty grubs around here, they get into damp logs and make a clicking noise when they chew. I once cut down an aspen tree and a huge grub came out and sat on the stump. It was enormous, the size of my fist anyway. I never saw such a grub before or since. I have no idea what it was. I ran to call my freinds to see it, but when I got back just seconds later, it was gone, no sign of it at all. That one would have made a nice snack.

I am glad the loos have sewers now. I was worried about all the flies you had last week. But of course good old England wouldn't let conditions get that bad. We sometimes have hourdes of biting flies around here, too, all different sizes. The big ones, horse flies, we call them, are pretty slow and stupid and easy to swat, but there are also little ones, almost invisible, called midges or blackflies. They swarm and their bites are awful, much worse than mosquitoes. It is not uncommon to hear campers in the cafe telling how they were driven out of the woods by the flies. They crawl up your sleeves and pant legs and make a terrible rash on ankles and wrists.

I have to say though that the insects in general for the past many years now have been down. I recall summers when dad had to stop to scrape them off the windscreen to be able to see to drive. There would be a thick paste of them on the bumper and grill. I never see that any more. And there seem to be fewer birds, fewer frogs, I don't know. Things are changeing.

We have lots of dragon flies this year. They eat lots of mosquitoes and midges, so they are a welcome sight. I don't know if you call them dragon flies in England. They look like little helicopters. Some are very beautiful, green and blue and all iridescent. They like to hover in open places, darting this way and that to scoop up a fly or mosquito. I drive slow when I see them. They can get out of my way if I keep it under thirty mph.

Today looks like another beauty. We had a thunderstorm this morning early, but the air is cool and not too humid. We don't get many 90 degree days, maybe for a week or so in the summer. And it is always cooler by the lake. The water stays near 50 F all the time, so you can always go to the beach and get chilled. One of the main reasons I chose to live here is because I do not do well in heat. Only a couple hundred miles south of here, in farm country, where I grew up, summers are hot and humid. I prefer to stay in the woods.

Be well, and thanks for the lingo. "Dint arf wiff," a classic! I think Robbie Burns would have liked that one.
