remains unchanging, space will expand indefinitely while increasingly isolated stars will slowly fade away and go cold, a phenomenon referred to as Heat Death. And if dark energy keeps accelerating the expansion of the universe, space itself will eventually be torn apart in the Big Rip

Big Rip

In physical cosmology, the Big Rip is a hypothetical cosmological model concerning the ultimate fate of the universe, in which the matter of the universe, from stars and galaxies to atoms and subatomic particles, and even spacetime itself, is progressively torn apart by the expansion of the universe at a certain time ...

What happens if the universe rips?

If the Universe holds enough matter, including dark matter, the combined gravitational attraction of everything will gradually halt this expansion and precipitate the ultimate collapse. Over time, galaxies, then individual stars, will smash into each other more frequently, killing off any life on nearby planets.

What is the Big Rip theory of universe?

The force of gravity that is holding objects together will be overpowered, ripping apart the space-time fabric and everything in between, like a rubber band stretched too far. This outcome is better known as the Big Rip Theory.

What are 3 ways the universe could end?

The rate of this expansion may eventually tear the Universe apart, forcing it to end in a Big Rip. Alternatively, the Universe could 'shrink', decrease or decay, effectively reversing the Big Bang and destroying the Universe in a Big Crunch. A third theory is described as the Big Freeze.

How many ways can the universe end?

The ultimate fate of an open universe is either universal heat death, a "Big Freeze" (not to be confused with heat death, despite seemingly similar name interpretation ⁠; see §Theories about the end of the universe below), or a "Big Rip" — in particular dark energy, quintessence, and the Big Rip scenario — where the ...

Could the Universe End by Tearing Apart Every Atom?

Will the Big Rip happen?

If dark energy remains unchanging, space will expand indefinitely while increasingly isolated stars will slowly fade away and go cold, a phenomenon referred to as Heat Death. And if dark energy keeps accelerating the expansion of the universe, space itself will eventually be torn apart in the Big Rip.

What was before the universe?

In the beginning, there was an infinitely dense, tiny ball of matter. Then, it all went bang, giving rise to the atoms, molecules, stars and galaxies we see today. Or at least, that's what we've been told by physicists for the past several decades.

Does space go on forever?

The observable universe is finite in that it hasn't existed forever. It extends 46 billion light years in every direction from us. (While our universe is 13.8 billion years old, the observable universe reaches further since the universe is expanding). The observable universe is centred on us.

What is the final state of the universe?

If there's more than enough matter-and-energy, the Universe will expand to some maximum size, the expansion will reverse to contraction, and the Universe will recollapse. The Universe expands forever, resulting in a Big Freeze.

Will the universe end or last forever?

Observations suggest that the expansion of the universe will continue forever. The prevailing theory is that the universe will cool as it expands, eventually becoming too cold to sustain life. For this reason, this future scenario once popularly called "Heat Death" is now known as the "Big Chill" or "Big Freeze".

What is outside the universe?

By definition, the universe is everything, so there is nothing external to it for it to expand into.

What would happen after the Big Rip?

If the Big Rip is correct, everything in the Universe will be reduced to its most fundamental constituents, in some strange parallel to the earliest stages of the Big Bang.

What created the universe?

Our universe began with an explosion of space itself - the Big Bang. Starting from extremely high density and temperature, space expanded, the universe cooled, and the simplest elements formed. Gravity gradually drew matter together to form the first stars and the first galaxies.

Will the universe become a void?

Ultimately, space could collapse back in on itself, destroying all stars and galaxies in existence, or it could expand into essentially an endless void. "The truth is that it's still an open scenario," said astrophysicist Steve Allen of Stanford University.

Does the universe have a beginning or end?

The usual story of the Universe has a beginning, middle, and an end. It began with the Big Bang 13.8 billion years ago when the Universe was tiny, hot, and dense.

Where does space end?

Practically, we cannot even imagine thinking of the end of space. It is a void where the multiverses lie. Our universe alone is expanding in every direction and covering billions of kilometres within seconds. There is infinite space where such universes roam and there is actually no end.

Does the multiverse exist?

Even though certain features of the universe seem to require the existence of a multiverse, nothing has been directly observed that suggests it actually exists. So far, the evidence supporting the idea of a multiverse is purely theoretical, and in some cases, philosophical.

How do space smell?

A succession of astronauts have described the smell as '… a rather pleasant metallic sensation ... [like] ... sweet-smelling welding fumes', 'burning metal', 'a distinct odour of ozone, an acrid smell', 'walnuts and brake pads', 'gunpowder' and even 'burnt almond cookie'.

How long would a human last in space?

"No human can survive this — death is likely in less than two minutes," Lehnhardt said. According to NASA's bioastronautics data book (opens in new tab), the vacuum of space would also pull air out of your lungs, causing you to suffocate within minutes.

How far in space have we gone?

The probe launched on Sept. 5, 1977 — about two weeks after its twin Voyager 2 — and as of August 2022 is approximately 14.6 billion miles (23.5 billion kilometers) away from our planet, making it Earth's farthest spacecraft.

Was the universe Born From Nothing?

The Big Bang theory says that the universe came into being from a single, unimaginably hot and dense point (aka, a singularity) more than 13 billion years ago. It didn't occur in an already existing space. Rather, it initiated the expansion—and cooling—of space itself.

What is older than the universe?

Far from being 13.8 billion years old, as estimated by the European Planck space telescope's detailed measurements of cosmic radiation in 2013, the universe may be as young as 11.4 billion years. If that is, indeed, the case, then Methuselah is one again older than the universe.

Can something come from nothing?

In the quantum realm, something really can emerge from nothing. In theory, the Schwinger effect states that in the presence of strong enough electric fields, (charged) particles and their antiparticle counterparts will be ripped from the quantum vacuum, empty space itself, to become real.

Will space ever collapse?

It could either expand or contract rather than stay stable. With enough matter, gravity could stop the universe's expansion and eventually reverse it. This reversal would result in the universe collapsing on itself, not too dissimilar to a black hole.

Are we falling in space?

(B) An astronaut orbiting the Earth does feel weightless because there is no ground or normal force to counteract the force of gravity. Thus, the astronaut is falling. However, since the astronaut is also moving forward super fast, he/she continuously falls around the Earth rather than crashing into the Earth.
