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.
What are the 3 types of universe?
The Universe is thought to consist of three types of substance:
normal matter, ‘dark matter’ and ‘dark energy’
.
What are the three fates outcomes of our universe and what are all three based on?
Notably, the ultimate fate of the universe depends on three things:
the universe’s overall shape, its density, and the amount of dark energy that exists
.
What are three characteristics of the universe?
- The universe is… All of space and everything it contains. …
- The Big Bang Theory. The universe began very hot, small, and dense super-force, with no stars, atoms, form, or structure.
- The 3 Major Parts of the Universe. 1) Stars. …
- Stars. 1) made of gas. …
- Nebulae. …
- Galaxies. …
- 3 Types of Galaxies. …
- Elliptical.
What happens when you reach the end of space?
It will expand forever;
the galaxies within groups and clusters will merge together to form a giant super-galaxy
; the individual super-galaxies will accelerate away from one another; the stars will all die or get sucked into supermassive black holes; and then the stellar corpses will get ejected while the black holes …
How long will universe last?
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.
What is outside the universe?
The universe, being all there is, is infinitely big and has no edge, so
there’s no outside to
even talk about. … The current width of the observable universe is about 90 billion light-years. And presumably, beyond that boundary, there’s a bunch of other random stars and galaxies.
Do we live in an open or closed universe?
With some rather large uncertainties, all methods point to
the universe being open
(i.e. the density parameter is less than one). But we need to remember that it is unlikely that we have detected all of the matter in the universe yet.
What is bigger than the universe?
The universe is much bigger than it looks, according to a study of the latest observations. When we look out into the Universe, the stuff we can see must be close enough for light to have reached us since the Universe began.
What are the two features of the universe?
- Galaxies-It is a system of millions or billion of stars containing gas and dust. Galaxies held together by Gravitational attraction.
- Stars-They are vast number of celestial objects that are visible in clear night sky.
What are the main characteristics of the universe?
The Universe is
everything we can touch, feel, sense, measure or detect
. It includes living things, planets, stars, galaxies, dust clouds, light, and even time. Before the birth of the Universe, time, space and matter did not exist.
What are the features of universe?
- GALAXIES. a system of millions or billions of stars, together with gas and dust, held together by gravitational attraction. …
- STEADY STATE. …
- STARS. …
- THE BIG CRUNCH. …
- NEBULAE. …
- BIG BANG.
Does the universe have an end?
The end result is unknown
; a simple estimation would have all the matter and space-time in the universe collapse into a dimensionless singularity back into how the universe started with the Big Bang, but at these scales unknown quantum effects need to be considered (see Quantum gravity).
What will be the last thing in 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 happens when you reach the edge of the universe?
Since these
distant galaxies are receding away from earth
at a speed faster than light, the light from these galaxies will never reach us, no matter how long we wait. … The edge of the observable universe cannot keep up with the expansion of the universe so that many galaxies are eternally beyond our observation.
What will happen in 100 trillion years?
And so, in about 100 trillion years from now, every star in the Universe, large and small, will be
a black dwarf
. An inert chunk of matter with the mass of a star, but at the background temperature of the Universe. So now we have a Universe with no stars, only cold black dwarfs. … The Universe will be completely dark.
