What exists beyond the solar system?

Answer 1

The universe is a concept of space and time. These two dimensions (so strongly associated with each other in relativistic physics that they are combined in the idea of space-time) may not exist outside this universe. The word "beyond" is already related to space-time. We cannot define what is outside, beyond, before, or after our universe because these concepts are only known to apply in the space-time universe itself. Time and space exist because this universe has these two dimensions. Other dimensions and concepts may be scattered across all that we do not know. It does not have to be time after this universe or by that matter before. For example, where does the mass that is pulled into black holes go to? It is clear that it is no longer in our space and time, because all that stellar matter would not fit in a single point. There is no simple answer to this question. Since we do not possess the capabilities to explore a space that is beyond our senses at the moment, we cannot know what is beyond. As it is unobservable, it is only a subject of our speculation. There are mysteries inside that we have not unraveled yet.

Answer 2

Beyond the solar system, there are billions of other star systems, galaxies, and cosmic structures in the universe. This vast expanse includes planets, moons, asteroids, comets, black holes, dark matter, and various forms of energy and radiation. The universe extends infinitely in all directions.

Answer 3

The Universe is considered infinite and so there is no 'edge' as such but there exits and interesting theory whereby the universe folds back on it's self.

Many People however choose to believe that the universe is simply expanding and growing from the big bangand that we can never catch that up.

_____________________________________________________________

That depends on how much you want your mind to boggle.

If we consider the universe the edge of light that has been spreading since the big bang, then our universe is about 27.4 billion light years across (and growing). Outside that first wave of light is nothingness, it is void and emptiness. It has no matter, no energy, nothing.

However, if we wish to play with special relativity (and who wouldn't? That stuff is fun!) things get trippy. One would think that if we were on a planet at the very edge of the universe (like just a few hundred million miles from one edge) and we looked around, we would see that the universe is 27.4 billion light years one way, and only a few hundred million miles (just a few light minutes) the otherway (thus letting us know that we are on the edge). But no, things can't possibly be that simple, it has to be confusing or it isn't real science. Since light always travels at the speed of light in respect to an object, regardless of how fast that object is moving (so if you are traveling at the speed of light -1 meter per second, light will still zip on by you at 299,800 km/s), that means that if you look towards the far side of the universe, it will not appear to be 27.4 billion light years away, but only 13.7 billion light years. And that "close" side, which should be only a few light minutes still appears 13.7 billion light years away. In that respect, there is no "outside of the universe," not even nothingness or emptiness. The universe is literally everything.

At least this is what one would think if they did not realize that for the first 60 million years after the big bang the universe was too dense for light to travel across it. The only force that could expand at the speed of light during those early days was gravity in the form of gravity waves, which were not impeded by the conditions that existed during those first 60 million years (or similar length of time).

Answer 4

it is scientifically proven that universe in expanding from the day it created so it is physically impossible for a person to reach end of the universe in his physical life.we live in 3 dimensional world. we can not go our of this universe just like child in the womb completes his terms and comes in this world. in the same way we are passing our defined time in this universe no one knows what is after this universe until he dies in other world we change our distentions and leave this physical world.

Answer 5

The definition of "universe" that I like to work with is "everything, in all space and in all time",
something like the Hebrew word "olam".

If that definition is accurate, then there's no such thing as "outside" of it. As soon as
you start talking about a "what", you're referring to something that's inside it.

Answer 6

-Everything else. Besides, there may be other universes . <------- this guy was also right, only that everything else doesn't give an answer.

-There aren't any nature laws beyond the universe, so you can't exist there, and besides, universe's expanding higher than speed of light, so you can't even try escaping it, because mass can't go that fast.

Answer 7

What makes up outer space. Outer space has many galexies and we live on one of them, "The Milky Way Galexy". First there is the sun, then the inner planets, next the asteroid belt, and of course the outer planets. I will now talk about Earth, are planet. Earth is the only planet to have life on it. I love to see the Moon at night, sometimes if you look closely you can see Venus! Also Pluto used to be a planet but now scientists believe the planet is too small so they call it " The Dwarf Planet " . I hope this message gave you an idea on what makes up outer space. Bye :)

Answer 8

A very theoretical question. I would say that because the universe defines space itself then I'd say that nothing which has been created (not even space) exists beyond our universe. It's hard to imagine because our minds weren't equipped with that kind of mentality. For something to exist exist outside the universe; it would have to be eternal (outside of time) and uncaused. It would also be infinite in all ways; for it's dimensions are not defined. Anything else is hard to say without getting into the vast subjects of philosophy and theoretical physics.

Answer 9

Sorry to give you this type of answer but nothing, the edge of the universe is expanding at the speed of light and since only light can go that speed even light wouldn't be able to catch up and impact the "wall" so you can never see or touch it. There would be nothing to touch. Theoretically there is nothing obstructing your hand from going any further but because it is the edge of the universe there would be no space to put your hand in so you can only wonder.

Answer 10

The exosphere, or outermost layer of the atmosphere is practically a vacuum, and the second-highest layer, the thermosphere, has gas molecules, but they are few and mostly ionized. (see related question)
