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.
What is outside the expanding universe?
Answer. When scientists talk about the expanding universe, they mean that it has been growing ever since its beginning with the Big Bang. The galaxies outside of our own
are moving away from us
, and the ones that are farthest away are moving the fastest.

What is the biggest thing outside the universe?
| Structure name (year discovered) Maximum dimension (in light-years) Notes | Virgo Supercluster 110,000,000 A part of the Laniakea Supercluster (see above). It also contains the Milky Way Galaxy, which contains the Solar System where Earth orbits the Sun. Reported for Reference. |

What exists at the edge of the universe?
The Universe has many edges: the edge of transparency,
the edge of stars and galaxies
, the edge of neutral atoms, and the edge of our cosmic horizon from the Big Bang itself. We can look as far away as our telescopes can take us, but there will always be a fundamental limit.
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).
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.
Is space expanding faster than light?
But
no object is actually moving through the Universe faster than the speed of light
. The Universe is expanding, but the expansion doesn't have a speed; it has a speed-per-unit-distance, which is equivalent to a frequency, or an inverse time. … Approximately 13.8 billion years: the age of the Universe.
How old is our universe?
Using data from the Planck space observatory, they found the universe to be
approximately 13.8 billion years old
.
How fast is space expanding?
This means that for every megaparsec — 3.3 million light years, or 3 billion trillion kilometers — from Earth, the universe is expanding an extra
73.3 ±2.5 kilometers per second
. The average from the three other techniques is 73.5 ±1.4 km/sec/Mpc.
Will Earth go into a black hole?
Will Earth be swallowed by a black hole?
Absolutely not
. While a black hole does have an immense gravitational field, they are only “dangerous” if you get very close to them. … It would get very dark of course and very cold, but the black hole's gravity at our distance from it would not be a concern.
What is the fastest thing in the universe?
Laser beams travel at the speed of light
, more than 670 million miles per hour, making them the fastest thing in the universe.
What is the most powerful thing in the universe?
Quasars
inhabit the centers of active galaxies and are among the most luminous, powerful, and energetic objects known in the universe, emitting up to a thousand times the energy output of the Milky Way, which contains 200–400 billion stars.
What happens if 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 is inside a black hole?
HOST PADI BOYD: While they may seem like a hole in the sky because they don't produce light, a black hole is not empty, It's actually a lot of matter condensed into a single point. This point is known as
a singularity
.
How long would it take to reach the edge of the universe?
It's Space Day, but traveling the vast entity that is space would take far longer than a single day. The nearest galaxy: 749,000,000 (that's 749 million) years. The end of the known universe:
225,000,000,000,000 years (that's 225 trillion) years
.
