if the universe is constantly expanding I have 2 questions..?

Question

#1 what is the space that the universe is expanding into?
#2 will that space ever run out? if so what will happen then?

atcaug85- you are completly right..noones answer is any better then anyone elses beacuse NOONE knows for sure.

Answer 1

1# Anything outside the universe is unobservable and therefore any speculation about what exists or does not exist is therefore not science but philosophy. We will never know what, if anything is outside the universe.

#2 By applying hubbles law to observations of supernovae and gravitational lenses, many scientists have concluded that eventually the universe will have expanded so much that no other galaxies will be visible from Earth.

Answer 2

This is a BIG (not bang) if, because how we know that the universe is expanding?. SXX (science of the 20th century) teach us that the speed of the celestial objects recede from us. How can be known: by their REDSHIFT which they say is a measure of their spped, the faster they go the farther they are, because they are on their way since the big bang. But more and more astronomers find objects which interaxt each other which can not be because of the distance between them (even millions of light-years), then they can be not so far apart, then the redshift not an indication of speed!. Then the the universe is not expanding! (or at least there is no way to to tell either way). The other problem of the expansion theory is that there is not enough energy to fuel the expansion, so the SXX, to save the expansion theory, created the "dark energy" from nowhere, which nobody knows what it is, but even so they calculated(?) that it amount to 99% of the total energy of the universe...and 99% of the people believe them. Nonsense at its higher expression, So what is the answer: the electric universe. (take a look at www.thunderbolts.info)

Answer 3

When we say the universe is expanding we mean all the matter in the universe (all the stars and planets and dust) is spreading out. The space into which it is spreading is just space. The same kind of space the space shuttle is in at the moment, it is just nothingness. And because it is nothing, it can't run out and there is no end to it. How can nothing have an end?

Answer 4

#1: The space is a result of the universe, outside the universe there is no space. or time for that matter. Its hard to grasp, i know.

#2: It was theorized that the universe may collapse in what was called a "big crunch". Recent stellar data has disproved this theory, and infact suggests that the expansion of the universe is accelerating. This requires an as of yet, undiscovered force. Whether it be an affect of one of the four known forces, or a new one all together is unknown.

Answer 5

The common belief is that the universe is expanding. This is just the human perspective, and only considers this one posibility. What if it was not expanding at all, and that everything in it is just getting smaller and smaller? Everything would in effect be moving further away from everything else, and would give the appearance that the universe was expanding.

What if the universe was just a fixed size, and everything was shrinking? This is another possibility that should be considered.

Answer 6

this is actually a common misconception about the big bang. the universe is finite yet has no edge and no center. space-time itself seems to have originated in the big bang. the universe may be something like the two dimensional surface of a sphere, but the universe is four-dimensional. space-time itself is expanding, nothing exists, not even space-time, "outside" the universe for it to expand into. to quote a dead writer (1874-1946) "there's no there, there.

Answer 7

#1 there is nothing outside the universe only inside the universe does stuff exist. it is difficult to grasp, but there is nothing outside our universe except in the parallel universes theory.
#2 there is no stuff so nothing will happen.

oh and the universe will NEVER reverse it self for all the people who keep reading old works. there is an inflation speeding up factor due to the "anti-gravity" particle and that gets into the supersymmerty theory which i will not go into now. Also his name is Steven Hawking.

Answer 8

1 It expands into nothingness.
2 No it will not run out.
3 You wont live to tell, so don't worry

Answer 9

Empty area isn't our assets, universe occupies a undeniable quantity interior of infinite area, and shop increasing into empty area. Empty area maintains endlessly in 3-d. boost velocity is boosted by ability of dark power and passes the linked fee of sunshine various cases and reaches 7c. sure, receding velocity between 2 galaxies which located in opposite fringe of the universe is 7 cases quicker than velocity of sunshine. in any different case, how might desire to we clarify the size of the universe it fairly is ninety 3 billion gentle years in diameter, the place as this is age in user-friendly terms 13.7 billion years old?

Answer 10

#1 it's not, the matter within is just expanding

#2 yes, it will simply reverse and bounce back
