Can We Go To Another Galaxy?

How long would it take to travel to another galaxy?

To get to the closest galaxy to ours, the Canis Major Dwarf, at Voyager’s speed, it would take approximately 749,000,000 years to travel the distance of 25,000 light years.

If we could travel at the speed of light, it would still take 25,000 years!.

What galaxy do we live in?

The Milky WayThe Milky Way. 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.

How empty is space?

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.

Is hyperspace possible?

Technically, it would be possible for the Millennium Falcon to fly faster than light past Alderaan as it explodes and arrive at the Death Star in time to stop the weapon from firing in the first place. There are ways in which traveling through hyperspace would not require a violation of relativity.

Can humans survive light speed?

No, it is not possible for a human to survive travelling at the speed of light. Others have pointed out that it’s impossible to reach the speed of light, so they’re talking about the limits as you approach the speed of light. But at the speed of light, you experience singularity-like conditions.

What is the fastest thing in the universe?

Within the universe, light is the fastest things, light as no mass, things with no mass could reach light speed. A shadow is the next thing, which can travel faster than light.

Do wormholes exist?

Wormholes are consistent with the general theory of relativity, but whether wormholes actually exist remains to be seen. … A wormhole could connect extremely long distances such as a billion light years or more, short distances such as a few meters, different universes, or different points in time.

How long would it take to travel to Andromeda?

2.5 million yearsAlthough it may be one of the closest galaxies to our own, since the Andromeda Galaxy is 2.5 million light years distant it would take 2.5 million years to get there if (and it’s a huge ‘if’) we could travel at the speed of light.

Will we ever travel light years?

So will it ever be possible for us to travel at light speed? Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no. … So, light-speed travel and faster-than-light travel are physical impossibilities, especially for anything with mass, such as spacecraft and humans.

Can we ever reach Andromeda?

Currently there is no possibility but there might be a possibility in the future, Andromeda is about 2.53 million light years away from us and even if we somehow even travel at the speed of light, it would take 2.53 million years to get there.

Will we ever travel faster than light?

The fact is we’ll never be able to travel beyond the speed of light, at least based on our current understanding of established physics. … If a proton did achieve that speed, it would need infinite energy to go any faster, and we don’t have an infinite supply of energy.

How many galaxies are they?

Research released in 2016 revised the number of galaxies in the observable universe from a previous estimate of 200 billion (2×1011) to a suggested two trillion (2×1012) or more and, overall, as many as an estimated 1×1024 stars (more stars than all the grains of sand on planet Earth).

Will the universe end?

As long as the amount of stuff doesn’t go over a critical threshold, the universe will continue to expand forever, and eventually suffer heat death, freezing out. But if there’s too much stuff, the expansion of the universe will slow down and stop. Then the universe will begin to contract.

Will interstellar travel ever be possible?

Interstellar travel won’t be possible for at least 200 years, according to a former NASA propulsion scientist who has some new calculations. And by then, the spaceships we would design for the trip will be obsolete.
