Will the universe continue to expand?

Answer 1

Ok, most people here are stating outdated physics and knowledge.



The current theory is that the universe will continue to expand...forever, and faster and faster.

This is based on the findings of WMAP, a probe that studies cosmic background radiation, old light, and other things in the sky.


It found that 74% of the universe is composed of stuff that creates a negative gravitational field.


The universe simply isn't pulling in hard enough for the universe to collapse, or for the universe to come to a halt and stay that way.

This "Dark Energy" is pushing so hard the universes expansion is already escaping the pull of gravity, and will continue to do so, expanding faster, faster and faster.


The so called "Big Crunch" simply isn't realistic anymore and should not happen. Neither should the universe magically stop and stay in a steady state. No...such would defy the laws of physics themselves. Simply put, if the universe obeys its own laws it will continue to expand forever.

Answer 2

According to some theory I read:-

Space and time was created with the Big Bang, which was literally an explosion, due to which a huge force was exerted on the objects that got created and so these 'heavenly bodies' move away from the point of 'explosion' and from each other.

But these objects have gravitational pull. So they are also pulling each other, and since the Big Bang force was IMENSE, the gravitational pull cannot dominate over the force created by Big Bang.

Someone said they are accelerating, but what I know is that they are expanding with a decreased rate that is they are deaccelerating. Thats because of that constant gravitational pull and also because of the fact that the big bang had and INITIAL momentum only and not constant.

So ultimately one day (you and I would probably not be alive that day) the gravitional pull would start dominating and as a result everything in space would start coming towards each other that is the universe would contract, and everything would turn into the infinitely small and infinitely dense 'dot' from which they initially came. The 'to be' contraction is called 'The Great Crunch'.

But as somebody said its only a Theory but rest assured its not scepticism because it has reasons.

Answer 3

The big bang only occurred a few seconds ago in space time, when the force pushing out towards the universe becomes less than that at the source of the explosion there will be a 'Tsunami' affect which will cause gravity to pull all matter back to where it started like an elastic band. i.e. F1 (gravitational overload due to vacuum disintegration and substance overload) divided by F2 (force at centre of explosion) x distance between start and end of FI and F2 in light years x constant x time x e /mass x 1.101432.

The information given by WMAP and other probes and experiments carried out by the worlds leading scientists is limited to the knowledge we have to day. 'Reach' (Previous Ans) has over simplified the final action as far as our universe is concerned. The return theory or 'Tsunami' ( I know my spelling is not good) takes into account that there may be substance to space and the vacuum we are in is a removal of substance due to force (no human being has observed such aforce to comment but we already are aware that such a force occurred at the Bang). The mathematics are much more complicated to that which I sited but the foundations are there.

Answer 4

theres are several theories about this:
1. The universe expands indefinitely
2. it expands at a decelerated rate, which means it will reach a point when expansion is zero, then it starts to shrink at an accelerated reaching the "Big Crunch".
3. the universe will continue oscillation in size like a spring dash-pot system.

Answer 5

First, we observed that distant galaxies have been shifting faraway from us. it would desire to purely be one in all 2 issues: a million) we are the middle of the universe and each little thing strikes faraway from us. yet that isn't be able to be considering there is not any absolute physique of reference in the universe. 2) area itself expands. The galaxies are actually not shifting faraway from a center yet they have been each and every of the middle itself on the commencing up, the enormous bang. From that and extra precise calculation of the distances those galaxies have been, employing supernova mild as a yardstick, we found out that some distant galaxies had to be older than the universe. that did not made sense and the only answer became: the farther galaxies are increasing extra slowly than the closer ones. It skill that the universe strengthen is in actuality, accelerating. what is going to take place sooner or later is totally a wager. the main worry-free concept is the enormous Freeze: each and every little thing would be so a ways faraway from one yet another that there should not be adequate skill to maintain an atom mutually. purely distant debris in an in depth to 0 temperature countless universe will exist. possibly there is yet another faith for the universe yet we don't understand it yet.

Answer 6

NO. Whether it expands at all is a question mark. But some scientists think it expands based on the red shift. But red shift could be due to something else. There is a good possiblity that the expansion theory will be proven wrong.

The reasons are
1) There is collision of galaxies recorded.( If everything else moving away from everything else 'the balloon anology' then they can not collide)

2) Now they say it accelerate. No force for the acceleration is described.

3)The bias in scientific community. Most assume or want to say that big bang theory is valid because einstein say so. The expansion is one major proof of big bang. The universe originated from a single point.

4) No alterante theory to big bang so we stick with expansion.

Answer 7

I've been spending some time at my neighbor, La Palma observatory in the Canary Islands…I live near Alegranza in the northernmost part of the Canary Islands.

Anyway, according to my calculations we are in the cycle of a "big crunch". The observable universe light hasn't reached our eyes yet to indicate this. However, carefully using a new calculating device confirms that the process has begun about 100,000 years ago. That means our atoms will be... ripped apart. But don't worry, that won't happen for another 10 Billion years.

Answer 8

Yes, the theory that it will start to shrink eventually (The Big Crunch) has been disproved. Although can we really ever be sure about anything so huge as complex as the universe....To quantify the universe is the hugest and most complex thing that exists, it is everything!!

Answer 9

Yes, up to a certain point. Scientists are trying to figure this out by deciding whether the universe is enclosed or infinite i.e. it is like a layer which stars sit on.

Answer 10

Some scientists believe it will continue to expand until it can't anymore, and then it will start to implode (the opposite to explode / expand). Scary thought!
