if there is vacuum where universe "ends", what is that vacuum?

Question

and then what is.................?

Answer 1

You have just asked a question without an answer, No one actualy knows as we do not have enough information. However, we do have Inteligence. With inteligence we have lateral thinking. If space is infinite the human race will have died out before we can explore .000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 etc of it (but if it is infinite how do you quantify it?), I think that is probably an exageration.

The 'Theory of Reality' may pose a possible soulution. Let me remove all your limbs make you deaf and tear your eyes out; asumming you are realatively healthy in mind where would you be in terms of time space and location after I had lanched you into space in a shuttle going nowhere and heading nowhere? You have no contact with any other form of life.

Imprisoned in your own mind, slung out into a Cosmos full of matter that does not matter. Will your mind come to terms with reality? or evolve to a state of flux that is able to move about the cosmos in a blink of the eye you don't have (an imaginary Blink your possible quantative link) whether that blink is imagionary or not.

We will never procede one foot more forward in space exploration unless we understand the Theory of Reality and thus your answer will never be proved.unless some thought is given to a subject that is virtually ignored.

Answer 2

Vacuums are not seen as 'empty space' by many leading scientists. One of the most popular theories is that the vacuum between galaxies is full of 'Dark matter' which literally drives the universe's expansion. If the area outside the universe contained dark matter, as the vacuum inside is supposed to, the universe would not expand due to competing forces. So therefore there is no vacuum at the end of the universe.

We can answer this using philosphic science too. Physical vacuums only exist in our universe because physical beings inhabit it to percieve it. As nothing exists outside of our universe a vacuum cannot exist. All that exists is contained within our universe and contemplation of the exstance of anything outside of our universe is simply nonsence.

a vacuum in space is where there is no matter (gas liquid solid). there may be nothing where the universe ends like a giant dead end for existence or possibly as you leave the edge of the universe you simply re enter it somewhere else... or the vacuum may go on forever infinately; something we find hard to comprehend because everything we know and experience has an end: your body has an end where it meets the air around you, this has an end when it meets the walls of your house or the atmosphere of the planet, the planet has an end where it meets the solarsystem etc etc. your vision has an end where you cant see anymore..... we just don't know yet.. it's possible the universe keeps getting created in a endless cycle as it is born and then eventually collapses in on it s self to be reborn out of the collapsing forces... or the universe will just keep expanding... everything moving further and further apart until there are no stars in the sky because they r too far apart to be seen. then who knows what will happen..

Answer 4

That vacuum is the open space where the matter in the universe has not yet reached since the big bang. The expansion of the universe's matter is supposedly never bounded as to how far it can reach out, and thus, our universe existing as matter expanding in an infinite vacuum is the best way of explaining how it keeps expanding ever faster, yet not crunching back in on itself, or disappearing.

Answer 5

I'm going give you my answer based on Science so that I wont be alienated by the Highly educated people.

The vacuum in Space is created by the Sun. This is like having your Science experiment in high school. You have one big glass jar that your teacher required your group to bring as home work. A match box , cotton ball, tweezers and a small bottle of 80% proof alcohol.

It was a simple group experiment, you dip the cotton ball in alcohol using a tweezer, then one of the person in your group has to light the cotton ball and you placed it inside the glass jar and cover it.

This is similar how a vacuum in Space exist, not exacly the same. The Sun is feeding from all the planet gasses in order for it to exist. All planets creates different kind of gasses and release it on Space. By the help of the Sun light, plants and animals grows bacteria and all other living things' which help creates this gasses.

Answer 6

There is nothing outside of the universe, which is not the same as a vacuum!

Answer 7

At this point there has never been an Astronomer or a Cosmologist who went on record as specifying the "extent of space." Almost everyone has indicated that to the best of their understanding, space is infinite.

To help you get your arms around that idea, consider that astronomers can currently "see" with the best optical telescopes objects out in deep space at distances of up to 13 Billion Light Years in all directions from Earth. With the best Radio Telescopes, scientists and astronomers can
"detect" objects in deep space at distances of 40 Billion Light Years from Earth in all directions.

Now, those distance quotations do not indicate the extent of space (the end point), rather they just indicate where our equipment begins to fail to provide any useful information. Space continues on and on and on. We, however, do reach a point where we just can't "see" any farther with our present level of technology.

Oh yes, check this...One Light Year is roughly 6 Trillion Miles. Astronomers can see objects out to...

13 Billion times 6 Trillion Miles distance. Take a few minutes and write that number down using all the applicable digits and zeros...Do not take any powers of ten short cuts.
Can you do that? Please try. Now, I am not sitting here telling you that that number is "infinite", but I am telling you that it is huge, beyond most peoples' ability to comprehend...And that is not the end of space...

So, since no astronaut is ever going way out there, no probe will ever make the trip, and no one is out there trying to send EMail to us, why worry about it. You don't need to agree with me, you just need to recognize that it is really, really big.

and YES, Space is a vacuum. Deep Space is also a vacuum. Temperatures there are very, very close to absolute Zero Kelvin. So, in conclusion, there is no "end" of space that we know of.

Answer 8

Except that the universe does not end.

What is at the end of a sphere? Or better... WHERE IS the end of a sphere?

Answer 9

good question. new hybrid of the Dyson , maybe !!.. :)
