What are the possible outcomes of the universe?

What are the possible outcomes of the universe?

There are 3 possible outcomes for the universe: (1) an open universe, in which expansion will never stop; (2) a closed universe, in which the expansion will stop and turn into contraction; and (3) a flat universe, in which the expansion will slow to a halt in an infinite amount of time.

What are the 3 possible outcomes of the universe ending?

There’s three possible fates for the universe, one is called the Big Crunch, where gravity takes over and begins to pull the cosmos back, compressing to one point. Another extreme is the Big Rip, where the expansion of the universe just gets faster until galaxies, stars, planets, atoms and space itself is ripped apart.

What is the possible future of the universe?

The current expansion will continue forever, gaining speed, so that all the galaxies we now observe, 100 billion or so of them, will one day disappear beyond our ability to detect them. Our galaxy will be alone in the visible universe. And then, once the stars burn out, the universe will be truly cold, dark and empty.

What are the three possible futures of the universe?

There are basically three possible shapes to the Universe; a flat Universe (Euclidean or zero curvature), a spherical or closed Universe (positive curvature) or a hyperbolic or open Universe (negative curvature). A high mass density Universe has positive curvature, a low mass density Universe has negative curvature.

What happens to an open universe?

In such a case, the universe has no bounds, and will expand forever. This is called an open universe. If space has no curvature (i.e, it is flat), there is exactly enough mass to cause the expansion to stop, but only after an infinite amount of time.

Will the Big Rip happen?

One prediction puts this hypothetical “big rip” scenario 22 billion years in the future. The team found that the earliest a big rip can occur is at 1.2 times the current age of the universe, which works out to be around 2.8 billion years from now. “We’re safe,” says Sáez-Gómez.

How long will the universe survive?

22 billion years in the future is the earliest possible end of the Universe in the Big Rip scenario, assuming a model of dark energy with w = −1.5. False vacuum decay may occur in 20 to 30 billion years if Higgs boson field is metastable.

How will the universe change?

The Universe continues to expand even today, growing at a rate of 6.5 light-years in all directions per year as time goes on. The cosmic horizon grows by 60 trillion km, or 6.5 light-years in all directions, each year.

What are the 2 possible fates of the universe?

Just as Robert Frost imagined two possible fates for the Earth in his poem, cosmologists envision two possible fates for the universe:

• Endless expansion.
• The “Big Crunch”

What will be the fate of the universe?

There’s three possible fates for the universe, one is called the Big Crunch, where gravity takes over and begins to pull the cosmos back, compressing to one point.

Will the universe continue to expand forever?

If the geometry of space is open (and curved like a horse saddle), the universe will continue to expand forever, whether there is dark energy present or not. If it is, then dark energy will drive the expansion. The result? Heat death, the Big Freeze or the Big Rip is imminent.

What happened to the universe after the Big Bang?

Many scientists (astronomers and physicists alike) believe this is one of the most probable scenarios. The Big Crunch is thought to be the direct consequence of the Big Bang. In this model, the expansion of the universe doesn’t continue forever.

Can earth survive the end of the universe?

If Earth did manage to survive intact (spoiler alert: it won’t), the planet would explode about 30 minutes before the grand finale. Another popular scenario for the end of the universe that relies on deciphering the true nature of dark energy is the Big Freeze (also referred to as Heat Death or the Big Chill).
