I have a theory about existence and gravity. Tell me what you think please.?

According to Superstring Theory, gravity operates in 10 dimensions (for M-theory, it would be 11 dimensions) and the gravity that we feel is just a little leakage (like a leaking sprinkler), and that's why gravity is so weak compared with all the other forces. So in a sense, your alternate reality is in fact the othe 6 spatial dimensions outside our 3, but we can never see or touch them.\n\nBTW, the reason physicists say that they don't understand gravity is because we current do NOT have a complete quantum theory of gravity, but we do have a very well tested classical theory, and that theory is called General Relativity (by Einstein).\n\nRight now, Superstring theory and Supergravity are the 2 contending theories of quantum gravity. However, physicists have found that Superstring theory and Supergravity may in fact be the same theory but described differently mathematically.\n\nBTW, anti-gravity does exist and has been discovered recently, but was theorized by Einstein back in the 1920's. He called it, the Cosomological Constant. Today physicists call anti-gravity, Dark Energy, which exists everywhere in space and is part of spacetime itself. Again, we find that our own little reality is more than strange enough that we really don't need an alternate reality to make it stranger.

Gravity may only be a theory, but we have a good idea that it is real. We may not know the exact workings of gravity, but we know it is there.\n\nGravity affects everything. It affects all the planets, it's what makes us revolve around the sun. I'm sure the 'devil' has nothing to do with making sure all the planets get around the sun. It's trivial, and you're theory is even worse than the theory of gravity because it has absolutely no backing. We can see gravity and it's effects everyday. Scientists don't know all about it, but for the most part, we know it's real. Your theory on the other hand, there is no proof of the devil. He's a made up character, fake. Then to say he pulls us down, you forgot to take into consideration everything else effected by gravity, not just humans. \n\nIf the devil is pulling us down so effectively, he must be extremely strong. Where is your God to pull us up? Shouldn't He be able to pull us up, if He is so great? Nope, still not happening.\n\nTheory disproved. Face it, religion plays no part in science. Religion's purpose is to make people feel good about themselves, and provide answers to the answerless (such as creation). Science is out to prove what happened, and religion serves as a temporary explanation for most.

It's all theory, we don't know if (something) can exceed the speed of light. I would argue that time would be void at that moment, but again it's my theory. Interesting thought though.

Neither,\n\nTheory is never proof so that's not it. Gravity is a weak force. M is an explanation why it is weak. Multidimensional theory is not about gravity, it's just part of it.\n\nEinstein tried to unify the fields, he failed. Many new theories came and went.... I'm not sure we 'got it' now. It is still a very unstable work in progress.

I agree that such an explanation is one possibility.  In fact, my failure to fully comprehend the Big Bang in a purely scientific manner is the only reason why I am an agnostic, and not an athiest.  I feel that I need to allow for the possibility.

This is the best theory I've seen:\n\nhttp://www.4815162342.com/forum/viewtopic.php?t=3377

Well if gravity is what Einstein said it is=Curvature of space time.\nThan you are going to find some space time and uncurve it!\nThis would be anti-Gravity.

Nobody really knows.  Einstein's special theory of relativity posits gravity as a warp of space-time caused by the object's mass, but that only pushes the question one layer further down.  All we know for sure is that gravity exists, is pervasive, and can be important.

I believe in the possibility of aliens. My theory is, why not? why would we be the only living beings in the entire universe?

This "nothing" is what we perceive without the laws of physics. Our universe is limited by the knowledge we have about it. Recent theories (the "M" theory) suggest that endless universes exist, and sometimes they even collide one into other. Probably, out there, beyond the boundaries of 12 billions light years, others dimensions, other plan of existence exist.

Guys, this question is a followup to hemanthjk's theory on space question, two questions back.\nHemanthjk, if you post a followup question, no-one will know what you're talking about unless you give some background.  One answerer to your original question suggested you post it here.  Why not?\nAbout NASA, you need to know that there are thousands, maybe more, of people with ideas on space, time and cosmology that they'd love to have NASA think about.  So many of these ideas are totally off the wall, or have a crucial error, or are valid but already known, that it would be stupid to spend the public's money reading, analyzing and replying to them, or even trying to filter out the new good ideas.  So forget NASA, use the forum that's available.  If the idea has merit it will eventually get the attention it deserves.

you should read more into string theroy and the M theory.  they are both very interesting.  it is hard to wrap your mind around but  this is just one universe that goes along a membrane of universes that goes on infinetely.  the science channel often has show that explin all this much better and they make it pretty easy to understand.

Errr...why wouldn't one believe in gravity?\n\nNow, I'm an atheist, therefore I don't know all that much about what God is and isn't meant to relate to, but I'm not sure why clinical insanity would do one any favours with Him.

This is an interesting idea, and yes it is plausible.  Unfortunately, there is no way for us to surmise whether or not it is true, so this is something that can never make the status of a scientific theory.  \n\n(Misconception: most people think a theory is just an idea, but a true scientific theory must stand up to experimental scrutiny in order for it to make the status of a theory.  Since this concept is impossible to test or verify, it can never be a theory, and must stay in the realm of ideas and friendly debates.)\n\nHere is another cool thing to consider:\nThe Universe cannot be infinite, because it is expanding, which points to its origin where everything began at the same point, namely the singularity of the Big Bang. Therefore, if it is expanding, it is bounded.\n\nHowever, it is thought that it probably doesn't have an edge, much like the Earth doesn't have an edge. If you started in a spaceship and went in a straight line, you would eventually end up where you started, much like if you started at the North Pole and went in a straight line, you would end up back the North Pole.\n\nThe reason: although you would be going in a straight line on the 2-D surface of the Earth, that line is curved in the 3rd dimension. So, if spacetime is curved in the 4th dimension, you could be going in a straight line 3 dimensionally, but it would be curved 4th dimensionally.\n\nHowever, one could look at it this way instead: The Universe does have a definite edge, but as ou approach that edege, you and everything else shrinks, which means you could never make it to the edge.  You wouldn't be aware of the shrinkage because even the measuring devices would be shrunk, so you would think you were going endlessly in a straight line, when in reality, you were approaching an actual finite edge, but never making it.  Again, it can never be tested, so just a thought ;0)

Same god. different perspective. we haven't seen even our solar system from all sides yet. The god I believe created universe can not be understood completly ever.

I was want to make something abundantly clear,\nTHERE IS GRAVITY IN SPACE! (despite what "keelahkat" says).\nGravity is a force of attraction acting between two masses at a distance...any distance.\n\nThe only way one would experience true "zero gravity" would be to travel an infinite distance away from all objects in the universe with mass.

There are only theories.\nLike the Big Bang. Check source.
