is the space-time continuam real

Answer 1

Has not been disproven yet!

Answer 2

Almost the same question was asked a few weeks ago, I replied with the following, which seemed to do the trick -

Y'know, I've been trying to get a handle on that for a long time, but so far I understand it to mean that post-Einstein, once you include time as a fourth axis to the 3 spatial ones, the universe makes sense in terms of our physical laws working everywhere and everytime. That is a neccessity of a good physical law - it must always work no matter where in the universe you test it or how fast you're travelling. In other words, translations and rotations of objects or fields or whatever must have no effect on the validity of the law. If you do not include time as an axis perpendicular to the 3 spatial ones (mathematically, of couse), what we predict won't agree with what we see, especially in such cases as high relative velocities (as in approacing the speed of light), and strong gravitational fields. Amoung the oddest result of this view is that, in truth, all time actually exists simultaneously, and there is some not-quite-understood mechanism that only lets us see one instant at a time.

Anyway, to answer your question, "How does spacetime work?", the answer is, much better than space or time alone and separate. They are, in fact, as inseparable as the pair of poles of a magnet.

This all might be not quite accurate, especially since I'm so far just an "armchair physicist" with no formal education in the area, (tho I'm looking forward to taking physics, including the higher levels, if I can ever get thru these friggin' calculus classes). Anybody else have something to contribute or set me straight on??"

To this I would add that to understand the concept fully, one needs to explore tensors - see wikipedia for more info on that subject.

Answer 3

All indications are that it is real. Most of the ideas of General Relativity have been tested repeatedly and proven to be true.
It was first proven during a total eclipse of the sun back in the 1920s...Einstein predicted that a stars apparent position in the sky will appear to shift if it's just behind something with a high enough gravitational field. For us, the sun was the only thing to test it with. Not only did the star appear to shift, it did so at exactly the angkle einstein predicted---1.75 arc seconds...about 1/30th the apparent diameter of jupiter.
The idea being that light will travel in a straight line UNLESS the properties of space are curved. Since light has no mass, it's the only explanation of why its affected by gravity.

Answer 4

Many of Einstiens predictions concerning relativity have been proven experimentally, including time dialation. With the advent of extremely accurate atomic clocks we can actually measure a small but repeatable time difference between two synchronized clocks when one is sent around the world on a jet and the other stays at home.

A note to one of the posters, time is not the fourt dimension we add to x, y and z, t xv or time multiplied by velocity is the addtion.

Answer 5

No. There are ten dimensions. Length, width, height, weight, area, volume, mass, velocity, time, and infinity. I know that was not your question. In order to comprehend space one must know how it came to be and what is in it. Understanding Time is really simple. Time for you started at your conception. You fail to realize that you were before that time came to be. Understanding the Universe is the underling question here.

Answer 6

This was a partial anwer to how nthe universe works. The other part was Quantum physics, and both theories eventually clashed until a new one which includes both came out: superstring theory:

Answer 7

No! None of it is real! Space doesn't even exist! It was made to cover up God!!! You're all ignorant!!!!!

Answer 8

We live in a perceived 3 dimensional world. Up-down, right-left etc. Now, Think of a two dimensional space, like a flat safety net.

Now think of putting a bowling ball on the net and it will bend down because of the weight. Next, anything you put into that net will go toward the bowling ball.

The same thing happens in space, everything bends toward that particular gravitational mass, even light... because it's bending space/time, which can be accurately measured.

The bending of light lead to the definition of the speed of light or the distance between very huge objects with very great distances.

Space/Time measured is how we were able to send astronauts to the moon. It was because NASA was able to measure the speed of light to calculate the exact orbital take off and landing with exact precision to the millisecond.

Space/time is a tool scientists use to measure mass and distance.

For example, each visible star you see is how it looked millions of years ago and not how it looks to this minute, depending on the distance of that star.

You can ponder this on a clear night at home. Look to the nearest visible Galaxy to the naked eye. This galaxy is called Andromeda and you are actually observing what it looked like 2.5 million "light years" ago, because that is how long it took the light to reach you!

Thus, we measure that distance by calculating the speed of light, therefore getting an accurate distance of the galaxies space in time. In short, this is called space/time.

Once you reach the speed of light, it is traveling with you and therefore, things appear exactly the same as the image of what you see is traveling with you.

Light travels very, very, very fast. It cannot travel any faster than it travels because it cannot go forward in time. It's a constant and accurate relative speed.

for example, we've broken the sound barrier with air craft. You can shake the earth with what is called a "sonic boom" because sonic air craft have broken the sound barrier. The speed of sound is also a relative and accurate measurement based on the density of our atmosphere and cannot go any faster than what has been accurately measured.

The measurement for space/time at supersonic speeds is called Mach. Mach 1 breaks the sound barrier. Mach 2, 3, and 4 are all supersonic speeds.

In comparison, light travels 186,282 miles per second. This means that light reaches us from the Sun in about 6 seconds. So, if the sun exploded, we would experience it about 6 seconds later.

When measuring space time, we are able to go back in time by locating and seeing the beginning of the Universe. Such as quasars. These glowing vibrant balls of energy existed before galaxies ever existed.

Even though Quasars no longer exist, we can measure when they did because of space/time. We can actually SEE them.

Light waves are a vibrating frequency. Vibrations of waves defign, microwaves, gamma waves, and what we perceive as solids like you and me or a chair etc...

Everything is vibrating and depending on the frequency is of a particular radiation. One particular frequency is what our eyes are designed to see, we call it light.

All life with eyes are designed to pick up on a particular vibrational frequency. It does not have to be the light we see. There are vibrational waves called infra-red, and there are animals designed to only see that which we cannot see which is infra-red. Thus, they can hunt and see objects in the pitch of black very accurately.

Scientists have duplicated infra-red detecting instraments and telescopes both in space and in the lab and we can also make Infra Red visible to the naked eye.

In this manner, we can see objects in the Universe and measure them through space-time that visible light does not see. The same thing with microwave radiation. That is how we finally saw the big bang. Scientists are now mapping the big bang and it looks like it's going to be very accurate as to where the galaxies were forming before they formed. The big bang will no longer be a theory anymore.

Who knows, scientists are now speculating on more than one big bang and many of them taking place in parallel universes. Aren't mathematics fun?

Anyway, thanks to Einstein and currently, Steven Hawking who just won the most prestigious Laureate award in over 150 years, who updated us and made Einstein’s information even more accurate than before, we now can talk about what we thought were unusual behaviors in space/time with better explanations.

Go to PBS.ORG and look up Steven Hawking. This man has expanded since Einstein and is well respected the world over for his work.

Space-Time Continuam is real and you and I??? We are made out of vibrational energy vibrating billions of times a second. We are space-time.

So, in conclusion, ponder this... If the Galaxy Endromeda is 2.5 million light years away, that's 186,282 miles per second times 2.5 MILLION, traveling at light speed... It would take us about 10,000 years to reach that galaxy!

Once we reach that galaxy, we will be seeing a more current and accurate position and shape of that galaxy, but the farther we look out to it's milky way... we are still seeing distant stars within that galaxy (just like our milky way) that are thousands of light years away instead of millions... So, it may be more visually current but we are still seeing what they looked like in the past.

Answer 9

Yes , myself and my most of my family have experienced it.
