This may be a dumb question as I am no expert on this matters but curiosity compells me to ask anyway. Does energy have the same kind of bending effect on spacetime that causes gravity that matter does? Does the E=mc^2 make them interchangable in this regard also? If we implode the Earth ripping...

I have to participate in a debate about whether motion has cause or not. Do you know of any book or website I could check to get prepared for my debate?

Dumb question...but I don't know the answer. Is there a way to determine if a piece of metal will cause electronic interference? Is it true only for ferric metals, or can any type of metal cause transmission problems? Cya later, alligator

What's preventing Saturn's rings from condensing into a moon? Or Jupiter's, Uranus' and Neptune's for that matter?

I thought of putting this in the social science or philosophy forums, but I don't want to get too abstract about it. This is just something I've found a little confusing during life. :redface: When great events and accomplishments happen, we celebrate them. We throw parties and serve lots of...

If an adult can be deathly allergic to latex, could a condom instigate an abortion? Also, since condoms are never purchased for underage users, neither will the morning after pill. The vaccine for genital herpes assumes that females will eventually have sex! You might as well rule out that...

A poor understanding of causality has deadlocked the discussion of a couple of video-game geeks, and so we have ventured on into the internets looking for a bit of professional help. Hope we can borow a couple moments of your brain time. (Please remember that this isn't really physics question...

I'd like to better define cause and effect in engineering terms so I thought what better place to start than finite element analysis (FEA)… ok, strange you may say. But here's the idea. In FEA, one might say that each element is acted upon by some kind of 'causal action' which affects the...

to center themselves on other craters? http://i43.photobucket.com/albums/e397/Bigpappadiaz/050606omcaldera.jpg That's the Olympus Mons cauldera. Plasma cosmologists say that this event occurred because the massive lightning bolt that created the "shield volcano" jumped from the lowest...

What causes gravity? I really don't understand it :confused: . What causes gravity? Relativity says its the "bending" or "curving" of space but what causes gravity? Also anybody that's interested in observing gravity look http://www.fourmilab.net/gravitation/foobar/" . thx

If you had the option of donating $1M to any cause you liked in the hopes of making a real difference. Which cause would you choose and why?

A causes B, and B causes A. A changing electric field generates a magnetic field. An electric field whose change is changing generates a changing magnetic field which itself generates an electric field. An electric field whose changing of change is changing generates a magnetic field whose...

I'm trying to ascertain if there is any "consensus" on the cause of coronal loops in current theory?

I have a laptop which has never been exposed to water or liquids. But somehow I have rust where my processor's fan blows out the extremley hot air prior to over heating. Does any know why there would be rust. Does it have to be from a moisture. Can it be from over heating of materials...

On Friday, I was outside nearly all day. I have bad allergies, and supposedly, the past few days have been particularly bad for allergins. Things that don't usually bloom together are, and pollen counts are supposed to be very high. Anyway, Friday I felt kinda crappy, just cause my body was...

if gravity is a property of geometry of spacetime then does it imply that space is an entity in itself as Newton hypothesized, i mean if space is curved by a mass of a body and therefore creativg gravity around a particular radius then doesn't it imply that space isn't relative to masses as...

Is gravity a result of the curvature of spacetime, or is it the curvature of spacetime a result of gravity? Or something else? Thank you.

I love simple phenomina like this .. finding something "everyday" simple, and then trying to explain it or find a cause in scientific terms. I say it is diffraction, but I'm not sure. Here's the setup: In a darkened room light a small source of light, like a candle. Close one eye and with...

«(...) a torque τ applied perpendicular to the axis of rotation, and therefore perpendicular to L, results in a motion perpendicular to both τ and L. This motion is called precession.»(http://en.wikipedia.org/wiki/Gyroscope) Why does this happen? Assumpting this makes all further calculus...

can friction cause torque?

Finally, we now know the cause of global warming http://www.nunatsiaq.com/news/nunavut/51223_10.html Here is Simeonie Aqpik describing the shift in the weather, and why the Inuit knew the climate would change. Most of what tells is exactly what the AGW scaremongers love to hear, but wait...

Is the diffraction pattern of two recti-linear slits or an annular aperture due to the photons that diffract off the atoms located in the topmost atomic layers of the slit itself? If my explanation of the cause of diffraction patterns is true, then what are the ramifications?

When dealing with the concept of Inertia (Newton's First Law of motion), is there an explanation of why this is so or do we accept it for what it is based on observations and experiments? While realizing that asking for more and more underlying reasons can be recursive and has to stop...

According to General Relativity the stars and planets cause a warp in the fabric of space time, right? Now, if planets' orbits are governed by the warping of the fabric of space time, then how are the gas clouds in Nebulas affecting that fabric? Also how do galaxies affect that fabric? Do they...

I really need help with this problem. I need to know how to work it and the answer. I am trying to review all these problems and they do not have answers. 2. It requires 242.7 kJ/mol to fragment Cl2 molecules into Cl atoms. What is the longest wavelength (in nanometers) of light that has...

This afternoon there will be a colloquium at my university on the topic of GRBs causing mass extinctions. It sounds like a pretty interesting topic and so I want to know what you guys think about it. Here is the offical email that was sent to my FSU account: There are two main theories about...

What's the cause?

I have such a question in my physics book: There are 2 statements below. Choose a if the second statement is an explanation of the first statement; otherwise, choose b : 1. Ammeter has a very small resistance. 2. The current in the circuit can be said negligibly affected when the...

hi i have fixed a simple circuit for lighting up a led.i have included a potentiometer. as the led is white i know that the voltage drop of the led is around 4v.when the potentiometer is at min resistance the voltege drop is actuallu around 3.8v.the problem is that when i turn the potentiometer...

why does the red dot on Jupiter i think its like a storm or something or a hurricane but does anybody know why it does not stop? and the cause of it ? thak u craig

Just a news release I though you might be interested in: "A controversial chemical, perfluorooctanoic acid (where's my Merk?), used by DuPont Co. to make the nonstick substance Teflon poses more of a cancer risk than indicated in a draft assessment by the Environmental Protection Agency, an...

Some physicists have suggested that the big bang might have been a black hole. Lee Smolin for instance has speculated that instead of a singularity, black holes produce new universes. Has Smolin or anyone else for that matter given a process by which a black hole may explode? Apart from...

Just a quick one guys. I have been revising and I have come across a question that I thought I knew the answer to. Q. There are many isomers of C16H34. What features of the structure of an isomer would cause it to auto-ignite easily? I thought that isomers with 'branches' (e.g. methyl-...

I just heard this on some astronomy show. When the big quake hit Northridge, Ca, in 1994, at 4:30AM, electrical power was lost over a large area. When the quake ended, and when people went outside and saw the night sky, something that is almost never seen because of all the city's lights, it was...

hi guys . i read that friction can be attributed to the centripetal force that causes circular motion . now suppose we consider our circle as a polygon , say an octagon and a bike or car was going along one of the sides of this octagon if i were to negotiate a turn of an angle of 45 degrees...

how can the area or distance between two objects getting larger cause something traveling between them to strech?

Hey all. I felt really really dizzy today, and was about to vomit. But thankfully that didn't happen. I tried to seek out a proper answer to why i was dissy today, and i relised i was doing some things before i went a bit dizzy. 1). Played flute for quite a while (lets say about a...

I have recently come across the subject of harmonics in my new job and I am a little puzzled about them. I understand that they are produced by devices which draw current in a non-linear fashion and that they can travel throughout a network causing items to overheat and such like. BUT... I...

If the physical world is causally closed, then there is a physical reason we talk about something called "consciousness." Any claims we might make that it can't be physically explained become somewhat outlandish, since the reason we make these claims can be. But even if the physical isn't...

What's the difference between "to cause" and "to make" in this context: http://www.sfu.ca/philosophy/swartz/freewill1.htm#intro Thankx.

Mutation is one of the important factors to cause evolution, but besides radiation, what cause mutation to happen? Is it happen naturally?

Couldn't the end of spacetime cause spacetime? As in some sort of looping paradox keeping existence in existence. I just wanted to ask this question. It's probably wrong but I wanted to know what people think.

Ever just wake up not feeling right? I'm not really sick, but I'm tired and my brain isn't working at its full potential. I can't think of anything funny to say. I might just crawl back into bed and unplug the phone for a few hours. I'm grouchy too. and my bum itches.

Just an interesting article... :wink: :biggrin: http://www.truthout.org/docs_04/101304G.shtml

Do you think computers cause... blindness, heartattacks, cancer, you know -- all of the ones that everyone include while generalizing causes. Do you think that research will show, that just like cell phones, computers can affect us in a negative way?

I remember reading a while ago that the fabric of space has a texture and thus would cause friction. Even in a perfect vacuum a spacecraft would slow down over time due to this. Is this an accepted theory?

Can anyone here explain me as to what causes the spin of a billiard ball and is this 'spin of a ball', in any way, related to the spin of the 'celestial balls'?
