If this is true, Superman's way of going back in time would be accurate. If you could go fast enough to arrive at a place before you left and all....
but if you can not exceed the speed of light you could only slow time down…..humm maybe superman is only extra special man……..

I guess then the question would be "Is the speed of light fast enough to get you there before you left?"

I guess then the question would be "Is the speed of light fast enough to get you there before you left?"
I wouldn't think so. Light does not arrive at it's destination before it leaves. You would have to break the universal time barrier - go faster than real time, not time on the clock. I would think that would mean that you would have to travel faster - possibly exponentially faster - that the rate at which the universe is expanding - but only in a microburst, else you might not only step outside the time barrier but also outside the universal barrier and go hurtling into the 'Outside' that we have been discussing. Does that sound reasonable?
Of course, if you surpassed the speed of light, would your molecular bonds hold or would your body be broken down into light energy? Also (just a smart alec question) if you are travelling faster than light, how do you see where you are going?
Besides, if you arrive before you leave, then there are two of you, which would mean that the exact same matter and energy - or matter and energy so close to exactly the same that it would likely make little difference - would exist in two different places at the exact same point in universal time. Something tells me that would be bad - especially if those two manifestations of the same matter and energy existed in close proximity to each other. In fact, wouldn't that mean that there would be more matter and energy in our universe's 'past' after you completed this process and less matter and energy in our universe's 'present' - enough matter and energy to compose at least your body, if not a vessel, etc. for you to travel in? At best you'd likely be caught in a loop because you could never progress - in normal time - past the point where you left the timestream. There would simply be a point in the collective experience of everyone experiencing the normal passage of real time where you just cease to exist. I guess it would create a sort of paradox, much like the famous grandfather paradox (you know - what if you travelled back in time and killed your own grandfather before he ever fathered any children, meaning that you never existed, meaning you could not have gone back in time to kill your grandfather, meaning he lived to father children, meaning that you do exist to go back and kill him, after all - and so on.)

Woooo, I have to be drunk before I start having these kinds of conversations.
Its possible that time doesn't exist and that our 5 senses only make it appear to exist. Until we can prove that other intelligent life exists, you could classify time as a human concept and accept the possiblilty that it isn't real. This is really more philosophical hogwash than scientific jabber, though. I can go on for hours with this...but I'm tired.

I think they answered this an SGSG1, you could go back and kill your grandfather because there are an infinite number of realties and you would just be changing one of them……..but that was a TV show and not reality, like what we are talking about…..

Hello. Just to get everybody up to speed on where physics is today, quantum physics was displaced by string theory, which, among other things, says that there are 10 dimensions, in the late eighties. The problem with string theory was that they ended up with five different sets of equations, and five different theories, each slightly different from the others. String theory has now been displaced by M theory.Which has an 11 dimensional universe. The thing that makes a theory different from a religious article of faith is that one must be able to make testable predictions based on the theory.Some people kind of stumble on the 11 dimensions thing, but it really isn't as weird as it might sound, if you start from scratch and think it through. Let's start with a theory which involes a purely 2 dimensional universe, like a sheet of notebook paper on a desk. In this universe the sum of the angles of a triangle will always be 180 degrees.However, if I took a sphere, like a globe of the earth, drew two straight lines down from the north pole to the equator with those two lines being at 90 degrees from each other, what I just did was draw a triangle with three 90 degree angles, which is immpossible in a 2 dimensional universe.My theory would need to be modified to include a third dimension.Now I'm happy with my new theory because the world that I can see is now more similar to the world my theory describes. But I notice a problem with my theory. It is not possible to account for motion in a purely three dimensional theory. If I add that fourth dimension of time, I am once again happy with my theory, because it now accounts for how something can be here and then be over there. It was moving in all four dimensions.Even if something is perfectly stationary in the three spatial dimensions it is still moving along the 'axis' of the fourth dimension of time. The only spatial dimensions are the first three. The other dimension is not an additional direction in three dimensional space. It is something different. As one starts to investigate the micro and the macro , there will be observations of things that don't really come up in the more mundane world that we all actually walk around in. Physics has had to incrementally add dimensions to account for the observations in exactly the same way we just added dimensions three and four to make the theory match up with the observations. M theory has allowed them to move back to the big bang and right on through the singularity to time before the big bang and to account for how the big bang happened. The big bang is no longer just an arbitrary starting point, it is an event that is understood to some degree.
Isn't this fun?
To go back to what was mentioned and what still floats around is the “big crunch” that the universe will eventually fall in on itself and then another big bang, this has been displaced because of numerous problems with it including recent finding have found that
the universe is not only expanding but is also accelerating at the rate it expands. Plus it has been determined that there is not enough matter in the universe (including dark matter) for their to be enough gravity to slow the expansion of the universe let alone cause it to fall back in on itself. There is a lot more evidence that’s just what I can remember off the top of my head.
Veronica, very good explanation of the first 4 dimensions……..
I’ll point out that M theory is the merging of several string theories, and M theory has not even been finished, last I heard they were going to have to come up with a whole new form of math to even complete M theory.
So they are nowhere close to be giving an explanation for the big bang, as I see it……..

Yes, but the triangle doesn't have three straight lines, (as they are all conforming to the curvature of the earth) allowing it to have the three 90º angles.

Its continuing to accelerate because of anti-gravity...atleast thats the last I heard the last time I delved into the subject.

Freeze something to 0 kelvin. What happens? We don't know. We believe that the subatomic particles cease to move and matter is really "frozen."
What happens at a singularity point? We don't know. We believe that infinite gravity infinitely bends time, so the classic "A Black Hole Crushes Stuff" approach doesn't work.
So, anyways, a singularity point is as close to what you're speaking of as we can sorta-visualize. Or, wait. Let's talk other dimensions. Draw a point. 1. Draw a line. 2. Draw a cube. 3? Nope. 2. Hahahah. Your Mustang- 3. Do you know what a Tessarect is? It's a 4 dimensional cube. The 4th dimension (laterally speaking) is a skew dimension. How about a pentarect? That's a 5 dimensional 'cube'. Where am I going with this? We think we see everything there is to see, but do we really know what matter is? If we can't percieve alternate dimensions that are strongly believed to exist, can we really define matter? (and mathematically speaking they do exist. I can take integrals all day long to calculate alternate dimensional densities and masses. Not like I can draw it though).
So, back to singularity. The most energetic particle (other than the elusive XHiggs Boson) we commonly see is the Photon. Light is part of the EMR spectrum, and it behaves like a particle AND a wave depending on how you look at it. It difracts, such as in the double-slit experiments, and it can be amplified through many means (LASER). It has a definite frequency and wavelength. The normal speed is calculated to an incredibly accurate number.
If there's a "thing" out there that can trap light, gammas, and x-rays, what do you suppose it is? Ok, ok. It does shoot out X-rays in the polar ejections (look at a Nasa picture of the Cygnus one). So, anywho, Einstein proved that time is a curvature that gravity strongly affects. So, if there's a point of infinite gravity, and gravity affects time, what happens? It's a limit! Yay I hate limits. Time becomes 0.
And this seeminly complicated stuff is actually pretty cool. Go on Wikipedia and search for some of this.
If you believe in the Big Bang theory, the entire Universe started out as a singularity point. Boom. It cooled down through the millenia to 3 degrees kelvin (as it is now). Graph out the cooling and you'll notice that it's a hyperbola. Does a hyperbola ever reach the asymptote? That's what a limit is. Some do, others don't. So, will the Universe ever cool to 0 kelvin? 0 kelvin is the asymptote, so I believe no. So, if everything we "know" to exist started out as a point of singularity- a point of zero time and zero volume and infinite mass, do we really have to search for a similar place. Look around. And by the way, many Christians disagree with this theory of creation. I'm a Christian and I strongly believe in it. "Let there be light". Hmm. 6 days? Who says those days were 24 hours long?
Wow... I got carried away there. Oops... Well, if you have any questions or you want to argue a point, I'd be glad to talk about this stuff. Catch me on AIM if you really want to... squirrel_Cv
**edit*** I just read some of the stuff you guys wrote on M-Theory. I disagree. I can't explain why without looking like a total nerd (If I don't already), but I just disagree. Not with what you said, but with the theory. I agree with the string theory, but not the fact that the universe is only 11 dimensions with 8 modes. If I really wanted to, I could draw a 2d representation of a 100 dimensional object. It would look like a giant mesh. So, why stop at 11?
Quantum Physics aren't terribly hard. Visualizing the material is harder than doing the material. And about the "Big Crunch" I believe in the "Big Rip" more. Lets talk Quantum for a sec. Why does the radius of an atom decrease as you go across the periodic table? More internal forces compress it when the orbitals are filling up. More protons and electrons. So, what happens when the internal forces of the universe; that which is holding it all together, go "out of range?" The Universe has a bad case of diarrhea- that's what. Fill a balloon up with helium. Let it go. Notice that it expands the higher it goes (well, you need a telescope to watch it). What happens when the difference in pressure exceeds the surface tension? POP. It doesn't collapse within itself. It pops. POP! There are theories about the surface tension of the Universe. So what exists outside the universe? Starbucks. That's what.
I think they answered this an SGSG1, you could go back and kill your grandfather because there are an infinite number of realties and you would just be changing one of them……..but that was a TV show and not reality, like what we are talking about…..
yes, all answers to all questions can be found in Stargate.
You must watch Stargete, just as you would use google.
