Does the universe have a center?
Space itself is curved, so as the universe expands from the Big Bang, it is somewhat like the two-dimensional space on a balloon.
But just like the surface of that balloon, there is no center in the universe..
What does space smell like?
Astronaut Thomas Jones said it “carries a distinct odor of ozone, a faint acrid smell…a little like gunpowder, sulfurous.” Tony Antonelli, another space-walker, said space “definitely has a smell that’s different than anything else.” A gentleman named Don Pettit was a bit more verbose on the topic: “Each time, when I …
Can the universe be infinite?
The observable universe is still huge, but it has limits. … That’s because we know the universe isn’t infinitely old — we know the Big Bang occurred some 13.8 billion years ago. That means that light has had “only” 13.8 billion years to travel.
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 is the bigger than the universe?
Galaxies come in many sizes. The Milky Way is big, but some galaxies, like our Andromeda Galaxy neighbor, are much larger. The universe is all of the galaxies – billions of them!
Do astronauts drink alcohol in space?
Alcoholic drinks are generally disallowed in spaceflight, but space agencies have previously allowed its consumption. NASA has been stricter about alcohol consumption than the Roscosmos, both according to regulations and in practice. Astronauts and cosmonauts are restricted from being intoxicated at launch.
What is beyond the edge of space?
Let us now go even beyond the edge of the observable universe. … The edge of the observable universe also marks what is called the particle horizon, the maximum distance one can see into the past.
What is the end of the 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.
Why is it dark in outer space?
Space is full of light, but it doesn’t look like it. The color black usually signals the absence of light. But inside the solar system, space is filled with light.
What is beyond time and space?
Beyond Time and Space is an anthology of science fiction stories edited by American writer August Derleth. …
What is space made of?
Outer space is not completely empty—it is a hard vacuum containing a low density of particles, predominantly a plasma of hydrogen and helium, as well as electromagnetic radiation, magnetic fields, neutrinos, dust, and cosmic rays.
What is the biggest star in the universe 2020?
UY Scuti. UY Scuti is the largest star in the universe and dwarfs all other stars. Astronomers working in Germany first discovered and identified the start in 1860 as part of their research at the Boon Observatory.
How old is space?
approximately 13.8 billion yearsAccording to research, the universe is approximately 13.8 billion years old.
What is the biggest thing in space?
The biggest supercluster known in the universe is the Hercules-Corona Borealis Great Wall. It was first reported in 2013 and has been studied several times. It’s so big that light takes about 10 billion years to move across the structure. For perspective, the universe is only 13.8 billion years old.
What is the oldest thing in the universe?
The search for extremely distant galaxies continues today. Astronomers have confirmed the discovery of one the oldest and most distant objects ever known in the universe — a star-forming galaxy 12.8 billion light-years away that started forming within a billion years of the Big Bang that kickstarted everything.
