What is at edge of universe?

The edge simply marks the dividing line between locations that earthlings can currently see and locations that we currently cannot. And although our observable universe has an edge, the universe as a whole is infinite and has no edge.


What is on the edge of universe?

The observable Universe is bounded by a 'cosmic horizon', much like the horizon at sea. Just as we know there's more ocean over the horizon, we know there are more galaxies (possibly an infinite number) beyond the cosmic horizon. Their light simply hasn't had time to reach us yet.

What is at the end of space?

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. But nobody knows for sure.


What is beyond our universe?

The trite answer is that both space and time were created at the big bang about 14 billion years ago, so there is nothing beyond the universe. However, much of the universe exists beyond the observable universe, which is maybe about 90 billion light years across.

What was there before the universe?

In the beginning, there was an infinitely dense, tiny ball of matter. Then, it all went bang, giving rise to the atoms, molecules, stars and galaxies we see today. Or at least, that's what we've been told by physicists for the past several decades.

What is bigger than universe?

No, the universe contains all solar systems, and galaxies. Our Sun is just one star among the hundreds of billions of stars in our Milky Way Galaxy, and the universe is made up of all the galaxies – billions of them.

How will the universe end?

Eventually, the entire contents of the universe will be crushed together into an impossibly tiny space – a singularity, like a reverse Big Bang. Different scientists give different estimates of when this contraction phase might begin. It could be billions of years away yet.

Can you touch the edge of the universe?

As far as we can tell, there is no edge to the universe. Space spreads out infinitely in all directions. Furthermore, galaxies fill all of the space through-out the entire infinite universe.


Where does space end?

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.

Will the universe go dark?

The known laws of physics suggest that by about 10100 (the No. 1 followed by 100 zeros) years from now, star birth will cease, galaxies will go dark, and even black holes will evaporate through a process known as Hawking radiation, leaving little more than simple subatomic particles and energy.

Does space have a smell?

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 ...


Is there a dead end in space?

In either case, you could never get to the end of the universe or space. 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.

Does the universe have a center?

According to all current observations, there is no center to the universe. For a center point to exist, that point would have to somehow be special with respect to the universe as a whole. Let us think about all the different types of effects that could create a center.

What is beyond the multiverse?

The Beyond is an unobservable space outside the Multiverse. It is the remnants of the Second Cosmos and is inhabited by the Beyonders.


Why is space infinite?

There's a limit to how much of the universe we can see. The observable universe is finite in that it hasn't existed forever. It extends 46 billion light years in every direction from us. (While our universe is 13.8 billion years old, the observable universe reaches further since the universe is expanding).

What created the universe?

Our universe began with an explosion of space itself - the Big Bang. Starting from extremely high density and temperature, space expanded, the universe cooled, and the simplest elements formed. Gravity gradually drew matter together to form the first stars and the first galaxies.

Can the universe RIP?

If dark energy remains unchanging, space will expand indefinitely while increasingly isolated stars will slowly fade away and go cold, a phenomenon referred to as Heat Death. And if dark energy keeps accelerating the expansion of the universe, space itself will eventually be torn apart in the Big Rip.


How many universes are there?

In a new study, Stanford physicists Andrei Linde and Vitaly Vanchurin have calculated the number of all possible universes, coming up with an answer of 10^10^16.

How many years are left in the universe?

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.

Will the Big Rip happen?

In their paper, the authors consider a hypothetical example with w = −1.5, H0 = 70 km/s/Mpc, and Ωm = 0.3, in which case the Big Rip would happen approximately 22 billion years from the present. In this scenario, galaxies would first be separated from each other about 200 million years before the Big Rip.


Will we ever be able to go back in time?

Time travel is possible based on the laws of physics, according to researchers. But time-travelers wouldn't be able to alter the past in a measurable way, they say. And the future would essentially stay the same, according to the reseachers.

What is the heaviest universe?

Black hole in galaxy NGC 4889. This unnamed intergalactic goliath is the current heavy-weight champion. Located in the constellation Coma Berenices about 300 million light-years from Earth, it has a mass 21 billion times greater than our sun.

What is Omniverse?

omniverse (plural omniverses) (science fiction) The entire set of co-existing universes, multiverses, etc.
