❓ Will the universe expand forever?
If dark energy in fact plays a significant role in the evolution of the universe, then in all likelihood the universe will continue to expand forever. INFINITE UNIVERSE? The density of the universe also determines its geometry. If the density of the universe exceeds the critical density, then the geometry of space is closed and positively curved like the surface of a sphere. This implies that initially parallel photon paths converge slowly, eventually cross, and return back to their starting ...

❓ Will the universe expand forever nasa?
The article reviews the problems of a dynamic or static universe, isotropy throughout the universe, the Cosmological Principle, the Principle of Equivalence, and redshifts. The problem of whether the rate of expansion is greater than the velocity for escape of galaxies from the universe, and the related problem of the total mass and average mass density of the universe, are discussed.

If the amount of ‘stuff’ (matter, energy, dark matter and any other materials we find) in the universe is too little, the universe will expand forever and as it does the energy inside will become more and more spread out until the ‘big freeze’. Everything stops, like an engine with no fuel.
Will the Universe Expand Forever? The recession of distant galaxies, the average density of matter, the age of the chemical elements and the abundance of deuterium together suggest that the expansion cannot be halted or reversed by].

I'm by no means an expert, but as far as I'm aware, all current evidence points to yes. These are the relevant facts that make us think so: 1. The universe is extraordinarily flat. We can understand what this means in 2D by considering triangles...

What’s more likely - that the universe will expand forever, or that it will contract in a big crunch, causing the end of the cosmos? – Mushahid, aged 16, Chitral, Pakistan.
1 Answer1. Active Oldest Votes. 5. Yes, if the Universe is matter-dominated and spatially closed, then a cosmological constant: Λ > 4 π G ρ c 2. Where ρ is the critical energy density (of matter) of the Universe, will cause it to expand forever. NB Where Λ is equal to this value you get the (unstable) Einstein static Universe. Share.
If the gravity from matter was insufficient to completely stop the expansion, the universe would continue floating apart forever. “From the announcements in 1998 and subsequent measurements, we ...

It is possible that the universe will last forever, or it may be crushed out of existence in a reverse of the Big Bang scenario, but that would be so far in the future that it might as well be infinite. Until recently, cosmologists (the scientists who study the universe) assumed that the rate of the universe’s expansion was slowing ...

An infinite universe can expand?
So it can't expand. In similar vein, in my opinion, an infinite universe can't expand. People claim the universe must be infinite because of the cosmological principle. But this is merely an assumption. There's an assumption that the universe is homogeneous and isotropic, but this isn't fact. You cannot use it to make sweeping claims about an infinite universe that was always infinite.
What makes the universe expand?
So, the Universe started with a bang. Everything was hot, dense, and expanding. It's 13.7 billion years later now, and our Universe is cold and sparse. The temperature of the leftover glow from the...
Does red shift expand the universe?
Redshift does not expand the universe. Redshift is a physical quantity that is used to describe the expansion of the universe. The current time has a redshift of zero. at redshift 1, the universe was half the size it is now. At redshift 2, the universe was 1/3 the size it is now, and so on. if redshift is z, then (size of universe at redshift z)/(current size of universe)= 1/(z+1)
What does the universe expand into?
The collection of galaxies that make up the universe is moving through space; therefore, the universe is expanding into even more space than it already encompassed. In our new picture, though, the galaxies are just raisins spread throughout the dough - their presence is largely irrelevant to the question of the universe's expansion.
What’s causing the universe to expand?
So what’s causing this expansion? Currently, we believe it’s mostly momentum left over from the Big Bang, and the force of dark energy will be accelerating this expansion. Forever.

Does universe go on forever?
That expansion might go on forever, but the universe itself is still finite. There is another ‘edge’ we can think about in terms of the universe. At a certain distance away from Earth, objects disappear from our field of view as the universe expands and those objects recede away from us.
Cosmology how can an infinite universe expand?
We can take this as a definition in the case of an infinite object; that is an infinite object, like for example, the infinite plane, is expanding when between any two points the distance between them is increasing. Share. Improve this answer. answered Dec 8 '17 at 20:46. Mozibur Ullah.
Eli5:what did the universe expand into?
ELI5:What did the universe expand into? Please help me out. I'm losing sleep here. My knowledge of physics is really limited, but if I understand the theory, in the beginning (before the beginning?) all matter was condensed into a "singularity." As Barenaked Ladies teaches us, the universe was in a hot dense state and then expansion started.
Expansion - how can an infinite universe expand?
It expands because of the pressure. However if that material was infinite in extent, the pressure is counter-balanced at all locations. So it can't expand. In similar vein, in my opinion, an infinite universe can't expand. People claim the universe must be infinite because of the cosmological principle. But this is merely an assumption.
Is “what does the universe expand into?
What does the universe expand into? Finally, we can return to the original question. In our old picture of the universe, the answer would be simple, although very unsatisfying. The collection of galaxies that make up the universe is moving through space; therefore, the universe is expanding into even more space than it already encompassed.

So, star formation won’t last forever in the observable universe. If you divide the infinite universe into finite regions/finite volumes, then you will realize …
Does the universe ever go forever?
First, it's still possible the universe is finite… The observable universe is still huge, but it has limits. That's because we know the universe isn't infinitely old — we know the Big Bang occurred some 13.8 billion years ago. That means that light has had “only” 13.8 billion years to travel.
Does the universe go on forever?
Many think it's likely you would just keep passing galaxies in every direction, forever. In that case, the universe would be infinite, with no end… Scientists now consider it unlikely the universe has an end – a region where the galaxies stop or where there would be a barrier of some kind marking the end of space.

Can miss universe keep the crown forever?
Answered 3 years ago. No….The miss Universe doesn't get to keep the crown forever. She can keep it for a year during her reign and then she has to crown her successor with it.
