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.

How far does space go?

When we take all of the available data together, we arrive at a unique value for everything together, including the distance to the observable cosmic horizon: 46.1 billion light-years. The observable Universe might be 46 billion light years in all directions from our point of view,...

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).

Where does space begin and end?

A common definition of space is known as the Kármán Line, an imaginary boundary 100 kilometers (62 miles) above mean sea level. In theory, once this 100 km line is crossed, the atmosphere becomes too thin to provide enough lift for conventional aircraft to maintain flight.

What is beyond 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.

A Mysterious Journey to the End of Space

Who created the universe?

Many religious persons, including many scientists, hold that God created the universe and the various processes driving physical and biological evolution and that these processes then resulted in the creation of galaxies, our solar system, and life on Earth.

Does the multiverse exist?

Even though certain features of the universe seem to require the existence of a multiverse, nothing has been directly observed that suggests it actually exists. So far, the evidence supporting the idea of a multiverse is purely theoretical, and in some cases, philosophical.

What is beyond the end of space?

If the universe is infinite, there is nothing beyond it, by definition. A finite expanding universe conjures up the idea that it would have a boundary or edge, separating it from something beyond.

Is there an end to 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.

Is there an edge of space?

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.

What was there before space?

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.

Can space not exist?

Special & General Relativity Questions and Answers

General relativity tells us that what we call space is just another feature of the gravitational field of the universe, so space and space-time can and do not exist apart from the matter and energy that creates the gravitational field.

What is outside of space?

Outer space is not completely empty; it is a near-perfect 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.

Does the sky go on forever?

As we pump more air into the balloon, we'd see the space or surface area expanding and every point or galaxy living on the surface getting farther and farther away from each other. That expansion might go on forever, but the universe itself is still finite.

Is there a center of the universe?

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.

Why can't we see stars in space?

The answer: The stars are there, they're just too faint to show up.

What will happen in 2024 space?

This article documents expected notable spaceflight events during the year 2024. The first two modules of the Lunar Gateway will be launched in 2024. NASA plans to launch the Artemis 2 mission on the Space Launch System, sending astronauts around the moon on a ten day lunar flyby.

Will space ever be empty?

So long as energy exists within it — even the zero-point energy of the quantum vacuum is sufficient — there will always be some form of radiation that can never be removed. The Universe has never been completely empty, and so long as dark energy doesn't decay entirely away, it never will be, either.

What is the farthest thing in space?

The galaxy candidate HD1 is the farthest object in the universe (Image credit: Harikane et al.) A possible galaxy that exists some 13.5 billion light-years from Earth has broken the record for farthest astronomical object ever seen.

Is space an endless void?

Ultimately, space could collapse back in on itself, destroying all stars and galaxies in existence, or it could expand into essentially an endless void. "The truth is that it's still an open scenario," said astrophysicist Steve Allen of Stanford University.

Is there a wall at the end of space?

It's a galaxy filament, a huge formation of galaxies that forms a border between the empty spaces of cosmic voids that together form the cosmic web. Hence, we call it a wall. Other, larger such walls are known. The largest is the Hercules-Corona Borealis Great Wall, which spans 9.7 billion light-years.

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 many dimensions exist?

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 many universes exist?

We currently have no evidence that multiverses exists, and everything we can see suggests there is just one universe — our own.

What is our universe called?

Universe is a name given to all the matter around us. Our universe is also called the cosmos. It is originally a greek word.
