In physics, a wormhole is a hypothetical topological feature of spacetime that is essentially a 'shortcut' through space and time. A wormhole has at least two mouths which are connected to a single throat. If the wormhole is traversable, matter can 'travel' from one mouth to the other by passing through the throat. While there is no observational evidence for wormholes, spacetimes containing wormholes are known to be valid solutions in general relativity.

when i think about the universe i dont think limits everything people have done was beyond the limits people can manipulate alot of things to get a better result then what is narutal so when einstein says nothing can go faster then light i say nothing that we have right now can go fast. once we have a dicens sphear then things will go alot fast population will explode space travel will happen daily and mankind will inhabit multiple galaxys. with a bigger population there will be a better chance of inventions furthering space exploration. this is a great vision but not one that i expect to see in my life time. any one have a different vision of the future?

Scientific Rule - Matter can not be created or destroyed
Scientific Theory - Black Holes are a singularity the genarate a HUGE amount of gravity, created by a star.
Scientific Theory - Big Bang; a spinning singulaity that blew all matter out in all directions.
How does the laws of physics not apply to the Big Bang, How? Why? did the Big Bang get started? ???????? This doesn't make any sense.
Are the scientists wrong?
Where's the explanation?
Huh!?

I know it's possible to buy books which give us the names of the various star constellations. 'The Plough', 'The Great Dipper' etc. But there is nothing obvious that makes these individual stars join together in such constellations. How did these stars come to be known by such names ? Who and when was this decided ? And are the constellations different in shape or even in their arrangements to, say, those of the ancient Chinese, or the ancient Egyptians ? If not, how could such arrangements have been universally accepted ?

if you suspend a few things and submit that the craft could even exist, go that fast, and stay in tact with you in tact as well,

what would theoretically happen?

Everything is caused by something other than itself.
Therefore the universe was caused by something other than itself.
The string of causes cannot be infinitely long.
If the string of causes cannot be infinitely long, there must be a first cause.
Therefore, there must be a first cause, namely God.
Everything that has a beginning in time has a cause.
The universe had a beginning in time.
Therefore, the universe has a cause.
The only thing that could have caused the universe is God (because the cause has to be spaceless and timeless).
Those who disagree with this argument do not believe there was a beginning of time. Doubters believe that the scientific account of the big bang did not occur as empirically proven by science, rather there was time infinitely in the past.
The human mind is unable to image a universe where there is no space and time. Image a box that has nothing in it. The space in that box is empty, but this does not mean that there is no space in the box. The same with time; imagine a universe where there is no time that flows linearly. It is impossible to image. The way our minds interpret our experience is by having space and having time. Those who believe that time is infinite, call upon their human experience, which tells them that imagining the contrary is impossible.

New scientific evidence from Time Magazine in June 2001 shows that the big bang occurred 15 billion years ago. Before the big bang there was no space and time. It is impossible for our human minds to comprehend what happened before the big bang, refer to the box again, we can only think of empty space not no space. It is also impossible for us to think of time that does not flow literarily. Time started when the big bang occurred and the big bang occurred everywhere at one time. Then all the matter and energy that the universe can use during its existence was created at the time the big bang occurred. A type of anti-matter pushes all the galaxies and solar systems away from each other. The speed at which this occurs is constantly getting faster, pushing galaxies and solar systems further and further apart. But these galaxies and solar systems are not moving into space that never existed. Outer space must be thought of as having positive curvature. A good way to image the way outer space is shaped by taking a piece of paper and making both ends touch each other. If something traveled in a straight line going further and further into space, it would in theory end up back where it started. So again in theory, a galaxy could end up exactly where it started at the dawn of time if it kept moving in the same direction. This will not happen because before this could occur, all the energy that the big bang created will be used up. Eventually the universe would enter a dark era. The only thing that will be left is cosmic waste. There will be no light and no energy 10^100 trillion years from now, just burnt-out cylinders of stars and dead planets. Eventually, all the matter will collapse into black holes then the black holes will disintegrate that matter into particles. These particles will bind together to form big atoms larger than the size of our universe. That’s the end. There will still be space, there will still be time, and there was a beginning to both. Something must have caused this universe to exist and the cause has to be both spaceless and timeless. The cause had to have been able to function where there is no space, which is unimaginable, and with no time which is also unimaginable.

It was not a freak coincidence that life can flourish on Earth and there was a cause to the universe that our planet is apart of. Barr showed evidence of how anthropic coincidences such the process of how chemicals came into existence and the necessity of quantum mechanics were both needed to function exactly as they do to allow life to exist. With scientific evidence showing how the universe both began and how it will end proves that the universe had a beginning in time but will have no end in time. Everything with a beginning in time has a first cause that the first cause of the universe had to be both timeles

given an infinite amount of time, then why does the universe still exist? I mean, is it not possible for the universe to be annihilated at some point? And if so, should it not exist anymore?

I got into a discussion with a friend of mine who claimed it had been proven; I disagreed because it is still called a "theory" as far as I know. If it has been proven would you please cite a source?

so i have to match the places/objects with the measurements
thanks!

Question posed to atheists, from an actual occurrence!
--Newton once had a skilled mechanic make for him a model of the solar system. Balls representing the planets were geared together so as to move realistically in orbit. One day an atheist friend visited Newton. On seeing the model, he operated it, and exclaimed in admiration, “Who made it?” Newton answered, “Nobody!” The atheist replied, “You must think I am a fool! Of course somebody made it, and he is a genius.” Newton then said to his friend, “This thing is but a puny imitation of a much grander system whose laws you know, and I am not able to convince you that this mere toy is without a designer and maker; yet you profess to believe that the great original from which the design is taken has come into being without either designer or maker!”
--Newton’s friend made a complete about face, with humility!
**What about atheists of today , do they lack the reasonableness that they claim true believers in the God of the Bible lack?

Does it mean that space-time is expanding only?
or
Does it mean that space-time and matter (ie. planets, stars) are all expanding?

This makes me feel like our brains as humans are so insignificant.
Anyone remember back when everyone thought the earth was flat? (not personally, of course)
I can't wait until (hopefully) one day, in the future, someone discovers what's beyond us. We're trapped in such a little net of what we can comprehend.
What if the universe is like a country... the galaxy is like a state, and us, earth, is like a city.
there may be more than just one country in.... whatever it is that's so much larger than us.
It blows my mind to think of the possibilities.

I answered a question with this, and now I'm just wondering if anyone feels the same way.

maybe i have it all wrong - just looking for thoughts from people who may know more about this subject than I do.

if the observable universe is made up mostly of dark matter, and if light is both a particle and a wave, then what is happening to all the light that is being emitted in every direction by stars?

are there any theories about all the light that is emitted but not absorbed or reflected by regular matter in the universe (not dark matter)?

are there any theories about the edges of the universe being composed of light particles or photons and such?
