What are 3 possible outcomes of the universe?

What are 3 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 different fates of the universe?

There are two mysterious quantities in the Universe that current models suggest will determine its ultimate fate: dark matter, matter we cannot yet detect directly, but which seems to be holding the Universe together; and dark energy, a mysterious energy that seems to be causing the Universe to expand at an …

What are the 3 forms of 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).

What are the two possibilities for the fate 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 are the possibilities for the future of the universe?

In a Universe that is expanding at an accelerating rate: • galaxies we now see will recede out of sight, one by one; • tens of billions of years from now, the Milky Way will be the only galaxy we’ll be able to see; • our Sun will have shrunk to a white dwarf star that will provide little light and heat to Earth; • …

What is the fate of the universe will the universe continue to expand?

The Universe will expand forever: If the mean density is less than the critical density, then there is insufficient mass within the universe to stop the expansion – the universe will expand forever. Ultimately, the galaxies will move increasingly further apart.

What is the most likely 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 the fate of the universe going to be?

The Universe will collapse in on itself: If the mean density exceeds the critical density, then the expansion of the universe will eventually cease, and the universe will begin to contract. Eventually, a fireball like that which initiated the universe’s expansion will result. This is referred to as the “Big Crunch”.

What is the fate of an open universe?

Open Universe: In an open universe a negatively curved universe without dark energy would expand forever. The universe would end in a heat death (known as Big Chill as well), or Big Rip. Basically a heat death is where entropy (or disorder) increases in an isolated system (system = universe).

What is the fate of the universe quizlet?

A theory that predicts that as the universe expands matter will be torn apart and result in the ripping of our universe. The theory that states that gravity will over come the expansion of the universe and bring everything together in an implosion. You just studied 10 terms!

Is the Big Rip possible?

One grim possible outcome is a Big Rip, which would ultimately unravel all matter down to the atomic level—though not for billions of years or longer.

Do we live in a 3 dimensional world?

We live in a world of three dimensions. We move through space , either left or right, forward or backward, up or down. Everything around us, from the houses we live in to the objects we use in everyday life, has three dimensions: height, length, and width.

How many fates does the universe have?

There are three possible fates, but which one will the universe choose? Measuring the temperature fluctuations in the universe’s relic radiation – the Cosmic Microwave Background – data from the now-defunct Wilkinson Microwave Anisotropy Probe (WMAP), is giving us an idea about the cosmos’ possible future

How many scenarios of the universe are there?

There were basically three scenarios, all based on how much matter the universe contained.

Is dark energy the driving force behind the fate of the universe?

If this is true, then dark energy is the major driving force behind the fate of the universe and it will expand forever exponentially. The WMAP satellite measures the basic parameters of the Big Bang theory including the fate of the universe.

What will happen to the universe in a big freeze?

The sky will be dark and as all of the stars begin to go out, the universe will grow, cold and lifeless in a so-called big freeze. Scenario 1: What will happen in a closed universe?
