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 is beyond the universe?
What lies beyond the universe? We are not sure but can theorize what lies beyond the universe that we know. Outside the bounds of our universe may lie a
“super” universe
. Space outside space that extends infinitely into what our little bubble of a universe may expand into forever.
How far does the universe go?
The comoving distance from Earth to the edge of the observable universe is about 14.26 gigaparsecs (
46.5 billion light-years
or 4.40×10
26
m) in any direction. The observable universe is thus a sphere with a diameter of about 28.5 gigaparsecs (93 billion light-years or 8.8×10
26
m).
What year will the universe end?
Thanks to the expansion caused by dark energy, within a couple of trillion years, all but the closest galaxies will be too far away to see. Then,
perhaps 100 trillion years later
, star formation will cease, as dense stellar remnants like white dwarfs and black holes lock up any remaining material.
Is the universe infinite?
If the universe is perfectly geometrically flat, then it can be infinite
. If it’s curved, like Earth’s surface, then it has finite volume. Current observations and measurements of the curvature of the universe indicate that it is almost perfectly flat.
How many dimensions are there?
The world as we know it has
three dimensions of space
—length, width and depth—and one dimension of time. But there’s the mind-bending possibility that many more dimensions exist out there. According to string theory, one of the leading physics model of the last half century, the universe operates with 10 dimensions.
How infinite is space?
Because space isn’t curved they will never meet or drift away from each other.
A flat universe could be infinite
: imagine a 2D piece of paper that stretches out forever. But it could also be finite: imagine taking a piece of paper, making a cylinder and joining the ends to make a torus (doughnut) shape.
What’s bigger than a 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.
How many universes are there?
There
are still some scientists who would say, hogwash. The only meaningful answer to the question of
how many universes there
are is one, only one
universe
.
What is our galaxy called?
Astronomy >
The Milky Way Galaxy
. … The Milky Way is a huge collection of stars, dust and gas. It’s called a spiral galaxy because if you could view it from the top or bottom, it would look like a spinning pinwheel. The Sun is located on one of the spiral arms, about 25,000 light-years away from the center of the galaxy.
What is the deadliest thing in the universe?
For one, falling into a black hole is easily the worst way to die. Halloween is a time to be haunted by ghosts, goblins and ghouls, but nothing in the universe is scarier than a black hole.
What happens when you reach the end of the universe?
Dark energy could still evolve
, leading to a Universe that might either recollapse in a Big Crunch, expand forever, or speed up in its acceleration and eventually tear even the fabric of space apart in a catastrophic Big Rip. The different ways dark energy could evolve into the future.
How cold is space?
Far outside our solar system and out past the distant reachers of our galaxy—in the vast nothingness of space—the distance between gas and dust particles grows, limiting their ability to transfer heat. Temperatures in these vacuous regions can plummet to
about -455 degrees Fahrenheit (2.7 kelvin)
.
Does time have an end?
According to Einstein’s General Relativity, which is our best current description of space and time, the only place where time – and also space –
ends is in a so-called singularity
. This involves gravitational forces becoming so intense that space and time lose all meaning.
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.
How old is our galaxy?
Astronomers believe that our own Milky Way galaxy is
approximately 13.6 billion years old
. The newest galaxy we know of formed only about 500 million years ago.
