Space spreads out infinitely in all directions. Furthermore, galaxies fill all of the space through-out
the entire infinite universe
. … This means that the universe does not wrap around and connect to itself like the surface of a sphere, which would lead to a finite universe.
Does the Galaxy go on forever?
Many think it’s likely you would just keep passing galaxies in every direction, forever. In that case,
the universe would be infinite, with no end
. … Scientists now consider it unlikely the universe has an end – a region where the galaxies stop or where there would be a barrier of some kind marking the end of space.
Is there an infinite amount of galaxies?
Our universe is just a finite number of galaxies rushing away from each other inside this empty infinite space—like a solitary skyrocket exploding and sending out a doomed shower of sparks.” But many cosmologists say,
no, there are an infinite number of galaxies in our infinite space
.
Is the universe infinite or expanding?
The universe encompasses everything in existence, from the smallest atom to the largest galaxy; since forming some 13.7 billion years ago in the Big Bang, it has been
expanding
and may be infinite in its scope.
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.
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 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.
Does space have a smell?
In a video shared by Eau de Space, NASA astronaut Tony Antonelli says
space smells “strong and unique
,” unlike anything he has ever smelled on Earth. According to Eau de Space, others have described the smell as “seared steak, raspberries, and rum,” smokey and bitter.
Are there astronauts lost in space?
A total of 18 people have lost their lives either while
in space or in preparation for a space mission, in four separate incidents. Given the risks involved in space flight, this number is surprisingly low. … The remaining four fatalities during spaceflight were all cosmonauts from the Soviet Union.
Where is end of space?
No,
they don’t believe there’s an end to space
. However, we can only see a certain volume of all that’s out there. Since the universe is 13.8 billion years old, light from a galaxy more than 13.8 billion light-years away hasn’t had time to reach us yet, so we have no way of knowing such a galaxy exists.
Are there an infinite number of planets?
The universe may be infinite, but we can only see a finite section of it due to the finite speed of light. … So there
would be an infinite number of
galaxies and planets in an infinite universe.
What is the galaxy we live in?
We live in one of the arms of a large spiral galaxy called
the Milky Way
. The Sun and its planets (including Earth) lie in this quiet part of the galaxy, about half way out from the centre. 100 000 years to cross from one side to the other.
What is above and below the universe?
This metric function tells us the “shape” of the universe. Our universe has a well defined metric at every point. Outside of the space where the metric is defined there is just nothingness.
Nothing above it
, nothing below it, nothing on the right or left.
Is space infinite in all directions?
Space spreads out infinitely in all directions
. Furthermore, galaxies fill all of the space through-out the entire infinite universe. … The flatness of the universe means that the geometry of spacetime is not curved or warped on the cosmic scale.
What is beyond the edge of the universe?
But
“infinity
” means that, beyond the observable universe, you won’t just find more planets and stars and other forms of material…you will eventually find every possible thing.
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.
