Will the universe continue to expand?
Answers:
Ok, most people here are stating outdated physics and knowledge.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.
Until the end of time and space itself, then it will carry on though the ages of myth that carry on before and after we are here in this short brief history of time.
nobody knows for sure
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.
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.
yes, you are safe. Nothing to worry about.
yes, but eventually, it will start to shrink.
Yes, it will until it reachs it's limits!!
Not if it contracts.
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!
It will in your lifetime and your children's lifetime.
It may as well. There's plenty of room in space. I'm still expanding in much less space.
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!
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.
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.
Has anyone read 'Vedic Physics' by Dr. Raja Ram Mohan Roy?

Hope you do not find it too heavy going.
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.
it has been for for time an beyond, it must exand to encompass fools like you
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.
yep. until the universe does a "reverse big bang" then it should continue to expand.
Yes, it is right now!
