What are the four possible fates of the universe?

There are hundreds of known cosmic events that could obliterate the life on our planet. High energy solar flares, cataclysmic impact events, gamma ray bursts, a nearby supernova, and on and on.

What are some possible fates of the universe when could this happen?

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 would be the fate of the universe?

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 Big Freeze theory?

The 'Big Freeze' The third theory states that the Universe could end due to a Big Freeze. Also somewhat conversely called 'Heat Death', this scenario is believed to be the most likely according to what we already know about physics and the Universe.

What are 3 possible outcomes of the universe?

The three possible outcomes include: an open universe, in which the expansion will never stop; a closed universe, in which the expansion will stop and turn into a contraction; and a flat universe, in which the expansion will slow to a halt in time—but it will never contract.

In what ways are the fates of the universe the shape of the universe and the average density of the universe related?

The geometry of the cosmos According to Einstein's theory of General Relativity, space itself can be curved by mass. As a result, the density of the universe — how much mass it has spread over its volume — determines its shape, as well as its future.

What are the two possible futures of the universe?

There are two possible futures for our Universe, continual expansion (open and flat), or turn-around and collapse (closed). Note that flat is the specific case of expansion to ever slowly speeds aproaching zero velocity.

What is the Big Freeze theory?

Cosmologists have pondered the ultimate fate of the universe, and many have converged on a theory: the “heat death of the universe,” also known as the “Big Freeze.” The Big Freeze theory suggests that, one day, all the energy in the universe will become evenly distributed, preventing any further action from occurring.
