    Without gravitation

    Well, I've been gone several months. I see most of you are still here. Anyway, I was simply going to answer Loren with, "No, nothing would have evolved without gravity" and be done with it. However the last post reminded me of a question I have that no one has been able or willing to answer...

    Doomsday Asteroid

    Oh well, I guess your right; it was a whimsical thought at best I suppose. You guys have pointed out a couple things that may be prohibitive, although I dispute a couple of points as well, but a chain is only as strong as it's weakest link, and this idea, obviously has a couple very weak links...

    Doomsday Asteroid

    Well, good to hear from someone addressing my questions. Grabbing an asteriod at it's slowest speed makes sense and would be the most logical with time permitting. I see you put some thought into this, thanks. So, we have a rock about 2 miles in dia moving at about 13 or 14 miles a second...

    Doomsday Asteroid

    RayJohn01, Hi. Theres no fetish, it's just the name of a band I played bass in till the drugs tore up a couple of the band menbers and ruined everything - - - :frown: oh well. Cling to life - - - hummm, - - I guess most of us do. Me ? I've done all the damage to my body that it can possibly...

    Doomsday Asteroid

    :zzz: O.K., it's 1:30 in the morning; everybody wake up. To start, "Our" volocity ranges between 24.1 and 31.1km/s. An asteriods volocity can vary greatly, as I expected. That in turn leads one to think there should be many within an acceptable range. There are 30 in excess of 200km in dia...

    Doomsday Asteroid

    Well, - - - that was certainly insightful, but perhaps we could start with an object slightly less than "Four million nine hundred ninty seven thousand miles in diameter"?? :wink: Did I read that right ?? My god, thats the size of a planetary orbit; albait a small one. I think one about five...

    Little Help - Every action equal and opposite reaction?

    Without reading the other 8 posts, my suggestion would be to go to the store and buy or "flip thru" some guns & ammo mags; the ones that have handguns, or more to your intrests perhaps, shotguns. These should answer these question, in particular, without reading too far. There are web-sites for...

    Doomsday Asteroid

    Well, - - - :frown: There are certainly more variables to be considered than I could possibly keep straight, but let's start at, what seems to "me" at least, with the most basic piece of information. I know it's all relative, but "is there" an average volocity range we could assign to...

    Doomsday Asteroid

    O. K. - - - Let us start with this; "What might the average speed of an asteriod be??" You should be able to do some calculations from there, you think? L8R.

    Doomsday Asteroid

    Perhaps, but for the most part, and there are always exceptons, we are able to detect asteriods on a collision course with earth sometimes years in advance. That considered, the nudge could be quite suttle, short term, and very effective. The size of the engines sent to retrieve the target would...

    Doomsday Asteroid

    :smile: I'd like to digress a bit on this topic. You know it wouldn't be very difficult to launch small "Engins" that could meet up with an asteriod, of any size you wish, then grappel onto it and thru the magic of vector steering bring it into a stable orbit for mining. Some of those things...

    What is nothing?

    :smile: Hello all. Antonio is right about the "Casimir Effect"; that was 1948, and the dudes first name was Hendrick. The experiment indicates some very compellingly possibiltys. "Acually, it's spacetime, not space alone, that is being stretched by mass." -- O.K., I'll grant you that, but it...

    What is nothing?

    :approve: Well, the last few threads "were" quite thought provolking. And thanks to Antonio Lao. I'll digest this and return. L8R

    What is nothing?

    :uhh: O.K. - - I'll agree that nothing is nothing. To have something, you need mass. Do we agree? But do we agree the Big Bang provided the essential requirments to create the mass we see today in our universe as it is today? All things considered, this mass originated at a singular point...

    Transforming mass and energy

    "Are there any examples of converting mass into energy or vice versa besides bringing together a particle and its anti particle? Or is this the only one allowed by conservation laws? So I do not mean the 'transformation' of energy and mass by changing your perspective, but the actual physical...

    What is nothing?

    Well, I certainly don't know where to go with this. For one thing, I'm not formally educated enough to use the proper terms when required and I have a hard time keeping all these concepts and theorys straight. It sometimes makes it difficult to convey what one truely means. Antonio, what can...

    What is The Theory of Everything?

    :approve: Well, - - you seek to speak with God. Just kidding, I'm not that religious. As most here may agree, T.O.E. won't happen in our lifetime. The "Theory Of Everything" will even have to explain how nothing exsisted before there was something; thats a problem, as well as a few other...

    What is nothing?

    :biggrin: Well, I've been just reading these threads for awhile and doing alot of reading; everything from Thales- about 600 b.c. to Newton, Einstein, Greene, Reese and Hawking. And all those in between. This "nothing" thing is simply not going to be solved in our time. If this "must" be...

    Which force drives the expansion of the universe?

    All systems will evolve to the lowest possible state of energy or the highest state of disorder and will tend to stay there unless energy is supplyed or order is restored thru the expenditure of energy. "ENTROPY". L8R --------"After all is said and done, Gravity Rules."------------- :approve:

    What is nothing?

    :frown: Well, we'll never "really" know the answer here; perhaps in a few generations. PhalanxGun - - it seems you've answered your own question a while back. You questioned how we could possibly invision "nothing", "It's like such & such - - -..." Well, you've done it. It's an intirely...

    What is nothing?

    - I love this topic :rolleyes: However it's quite problematic :cry: The closest you'll get to "nothing" would be the eternal moment that was just before the creation of the energys that E=mc2'd into matter. On one other point I read about 18 pages back; If a Big Bang explodes in the place...

    Mystery Before The Big Bang Unfolded

    Thanks Selfadjoint, you've answered a question I've just posted to you elsewhere. I'll review the sections on charm and color and such soon. MythioS, I've read of the "two" big bang theory but I've not found enough to convince me yet. It seems the lightest elements were formed as energys fell...

    Expanding universe and absolute zero

    Thanks SelfAdloint. I suppose your right, "Absolute" zero may not be obtainable: doesn't some theory state that you can never reach a point of zero by continually reducing the value by half? We will never reach a point where space will be as emtey as it was before the creation of matter, so that...

    Mystery Before The Big Bang Unfolded

    :rolleyes: Hello all. I've studied a lot on this "nothing" thing. It seems the most plausible way to start things out. However, I don't think there are any words to discribe a totally conceptual ideal of nothing. "Nothing" is an unstable state. We observe laws of conservation so this system...

    Expanding universe and absolute zero

    "Theoreticly", in a few billion trillion years, won't virtually "all" patricles disintigrate? Shouldn't it then be "0"-k degrees? Don't "all" systems seek their lowest state of energy if left un-hindered to do so? And then, would we not be left with a cold dark eternity waiting for anouther...

    Inflationary Theory. Absolute Vacume.

    Hello all. I'll try to make sense here but most of you, I feel, are beyond me intellectually; it seems I am best able to work through conceprtual and anilitical terms. I need help with any equations of formulas to really prove or disspell anything. I've read the entire thread and unless i've...

    Inflationary Theory. Absolute Vacume.

    Well, that took a while. I just saw your reply/replys. The comp burned in the house. took a while to find funds for a new one. Loren Booda: Just viewed your link. I'm impressed. however time is short. i've saved it to favorites to read after work. I guess laws of conservation (hereon "cnsvn")...

    A question about gravitons&photons

    Good to be back. House fire fried my computer. It's nice to see some of the same names; Nereid,"Is X physical', thats excellent as usuall. I like the way you can simplfy, or "dumbdify", a question. How "Could" one know if "X" is physical before "X" has been quantified? Turin, your descriptions...
