Quick Answer: What Happens If You Reach The Edge Of The Universe?

What’s beyond the edge of the universe?

Technically, this is the farthest point in space and also the farthest in time that we can observe.

That essentially forms the edge of the “Observable Universe”.

What lies even beyond that is what is known as the “Opaque Universe”.

This marks the limit of what we can observe but not what we can imagine..

What is at the 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.

Does space have a smell?

As it turns out, space actually does have a distinct odor. … Astronauts returning from space claim that their suits smell, in a word, burnt. The lingering scent of space is “acrid” and “metallic,” reminding the astronauts of charred meat or welding fumes.

Who created the universe?

In his 1988 book, A Brief History of Time, Hawking had seemed to accept the role of God in the creation of the universe. But in the new text, co-written with American physicist Leonard Mlodinow, he said new theories showed a creator is “not necessary”.

Will the universe be reborn?

The universe could bounce through its own demise and emerge unscathed. A new “big bounce” model shows how the universe could shrink to a point and grow again, using just the cosmic ingredients we know about now.

Is space expanding faster than light?

And space doesn’t expand at a speed; it expands at a speed-per-unit-distance: a very different kind of rate. … The restriction that “nothing can move faster than light” only applies to the motion of objects through space.

How can the universe be infinite?

Space expands, and hence grows, by virtue of creating new space. … In this way of thinking, the expansion of space is reflected in the distance between two such galaxies growing larger and larger over time. And that characterization of the expansion holds true whether the universe is finite or infinite.

How does astronauts poop in space?

Tthe poop is sealed inside a plastic bag and hauled off the next space trash day, Whitson said. … When it’s too full, astronauts must “put a rubber glove on and pack it down.” That’s what happens when the ISS toilet is working.

How long will the universe last?

Assuming that dark energy continues to make the universe expand at an accelerating rate, in about 150 billion years all galaxies outside the Local Supercluster will pass behind the cosmological horizon.

What is on the other side of a black hole?

The event horizon is a proposed boundary around a black hole. On the other side of it, the gravitational pull of the black hole is so strong that, in order to escape it, an object would have to be moving faster than the speed of light, a feat that almost all physicists agree is impossible.

Do things exist when not observed?

An item truly exists only as long as it is observed; otherwise, it is not only meaningless but simply nonexistent. The observer and the observed are one.

Are there other universes?

Together, these universes comprise everything that exists: the entirety of space, time, matter, energy, information, and the physical laws and constants that describe them. The different universes within the multiverse are called “parallel universes”, “other universes”, “alternate universes”, or “many worlds”.

How big is the universe if you could reach the edge of it what might you see?

The comoving distance from Earth to the edge of the observable universe is about 14.26 gigaparsecs (46.5 billion light-years or 4.40×1026 m) in any direction. The observable universe is thus a sphere with a diameter of about 28.5 gigaparsecs (93 billion light-years or 8.8×1026 m).

What happens when you get to the end of the universe?

The expansion slows, the Universe reaches a maximum size, and recollapses, ending in a Big Crunch. Expansion forever. … The expansion rate drops but never reaches zero; the Universe expands forever and ends in a Big Freeze.

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 outside the universe?

In our own backyard, the Universe is full of stars. But go more than about 100,000 light years away, and you’ve left the Milky Way behind. Beyond that, there’s a sea of galaxies: perhaps two trillion in total contained in our observable Universe.

What is the farthest we can see into space?

In December of 2012, astronomers announced a Hubble Space Telescope discovery of seven primitive galaxies located over 13 billion light years away from us. The results are from survey of the same patch of sky known as the Ultra Deep Field (UDF).

Can you reach the edge of the universe?

There is no evidence that the universe has an edge. The part of the universe we can observe from Earth is filled more or less uniformly with galaxies extending in every direction as far as we can see – more than 10 billion light-years, or about 6 billion trillion miles.

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 …

Where does space end and heaven begin?

Karman lineSo where does Earth stop and the heavens start? According to a paper that was published in the Journal of Geophysical Research-Space Physics, the border between the two—the so-called Karman line—sits 73.2 miles (188 kilometers) above Earth’s surface.

Are galaxies really moving away from us or is space just expanding?

However, the galaxies are not moving through space, they are moving in space, because space is also moving. … 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.
