is there any end of this universe?

Answer 1

According to current scientific theory, Yes there is an end. If the universe started with the big bang approximately 15 billion years ago, then 15 billion light years away, would be the edge of the known universe and beyond that is the "cosmic singularity", whatever that means.

In all probability though, when dealing with such theoretical concepts as the edge of the universe, it's more than likely that our best educated guess is way off the mark.

Answer 2

Universe has an end it yu mean by the term the galactic matter in theunverse .since the exact quantumo fhte matter is unassessable and unseeable , we can not say exactly what could be the end of it .but in a situationlike this , every point at any margin that separatews the matter from the space is an end only.the galalctic mater is spoace is like th sands on the beaches of all the continens . There is a defintie quantitiy of sand in this world .what is the exac quantity oif it? thre is no way to find it out . Ther are something that is impossible to assess. We eat several thousand pounds of food in our lifge time .We can not eat the entire quantity at any one time .That doesnot mean that we do not eat thousandsof pounds of food .We do eat over a period .It is like that .We can not assesscertinthings even though we know that thre is a definite quantity of something .But iof youmean the space by the term universe , it has no end .it can not have a boundry .Because spoace is nothig ness .It is not a thing but it is .Since it is nothing , it can have no shape and no boundary. "Nothing" alone can have this character and nothing else can be without shape or boundary.

Answer 3

We don't know for sure. But according to the widely accepted theory of Big Bang there are 3 possible 'ends':

- either the Universe expands forever because the Universe's expansion is stronger than its own gravity OR
- the gravity of the Universe is strong enough to make it stop expanding and starts collapsing again until a Big Crunch occurs OR
- the gravity of the Universe is strong enough to make it stop expanding but there is no collapse in the end because these two values are somehow fine-tuned.

If we knew how much dark matter there is in the Universe we'd be able to resolve this issue but currently we can't. So, everything is down to speculation.

Regardless, to me any of this scenario's sounds just gloomy...

Answer 4

No.

At the occurance of the Big Bang, light was given off, and the universe has a 'goal' or 'destiny' to contain anything inside it, including light. Light travels at the speed of light (300 000km/sec) so the universe will continue trying to contain it. So, in actual fact the universe has an end, but it expands constantly at the speed of light. Due to relativity, NOTHING can travel the speed of light, except light, so it is physically impossible to reach the end of the Universe, because even if you could. The Universe will simply continue expanding to contain YOU. So the answer to your question is: no.

Answer 5

Not really. According to some theory, it states that the universe is round and if you shot a bullet at a speed high enough, which is impossible, it could come back to the same position as it was before.

Besides the only space that exists is within the universe, there is no white colour or black outside it, because there just is no space.

Answer 6

there has to be end for the present univesrse
Four models are described
1 Closed universe:- where present expansion will be followed contraction leading to big Cranach
2 Open univesrse:- expansion will continue for ever Later followed by protan decay & only radiation may be left
3. Flat universe present expansionis follwewd by state of fixed state for eternity & protan decay & left with radiation
4 Acclaration of exapansion:- leads ( By energy mass equlance) increasing gravity by increasing mass. which may lead deacclaratiog & contraction & big cranch or it continue exand for ever where fate by protan decay & radiation

In all four model end of matter is certain but energy of universe & its fate & fate of space & time in non contracting models is probbably not known.
But all that begain should have end if not question comes how it begain at all. so be hopefull so end means new beganing

Answer 7

Is there an end to the surface of the Earth?

Think of it that way to make it a bit clearer. The Universe is finite (but expanding) and unending at the same time.

Although the exact shape has not been determined (and maybe never will be), thinking of it as an expanding sphere will help you visiluize it.

Answer 8

yes, but there is another universe where ours ends. It would take a whole life time to travel to the end. So its never going to happen realistically, and we will never know for sure.

Answer 9

scientists believe that the universe is still expanding but slowly! 14 billion years ago the whole universe was made in one second because of the big bang theory

Answer 10

d concept of universe is beyond ones reach(practically not virtually)
we know tat it is made of stars like our sun
all stars will die but at d same time new stars r born
so it is like a population having births and deaths
can u say when humans or dogs or cats will extinguish
no!
in d same way only the almighty one who has created this universe has knowledge about it
