The technology required to travel between galaxies is far beyond humanity’s present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.
How long until humans get to another galaxy?
So, to leave our Galaxy, we would have to travel about 500 light-years vertically, or about 25,000 light-years away from the galactic centre. We’d need to go much further to escape the ‘halo’ of diffuse gas, old stars and globular clusters that surrounds the Milky Way’s stellar disk.
What happens if you go into another galaxy?
When you’re wondering what happens when two galaxies collide, try not to think of objects smashing into each other or violent crashes. Instead, as galaxies collide, new stars are formed as gasses combine, both galaxies lose their shape, and the two galaxies create a new supergalaxy that is elliptical.
Can we ever reach Andromeda?
In Andromeda FTL drives reduce the mass of your ship, allowing it to greatly exceed light speed. The reality: We can’t do this. Even travelling at light speed you’ll take 2.5 million years to get there.
How long would it take to travel 25000 light years?
So it would take 25,000 years to get there if you traveled at the speed of light. Actually, that’s the amount of time it would take from the perspective of the outside world. From the perspective of a traveler moving at the speed of light, it would appear to take no time at all.
Can we ever travel faster than light?
Physicists’ current understanding of spacetime comes from Albert Einstein’s theory of General Relativity. General Relativity states that space and time are fused and that nothing can travel faster than the speed of light.
What happens if 2 galaxies collide?
The merging of galaxies will radically affect their shape. For example, two spiral galaxies can merge and form an elliptical galaxy. Sometimes even more than two galaxies can collide with each other. Merging galaxies can also trigger the creation of new stars.
What is outside the universe?
To answer the question of what’s outside the universe, we first need to define exactly what we mean by “universe.” If you take it to mean literally all the things that could possibly exist in all of space and time, then there can’t be anything outside the universe.
What galaxy do we live in?
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. 100 000 years to cross from one side to the other.
How old is our galaxy?
Most galaxies are between 10 billion and 13.6 billion years old. Our universe is about 13.8 billion years old, so most galaxies formed when the universe was quite young! Astronomers believe that our own Milky Way galaxy is approximately 13.6 billion years old.
How fast is the Milky Way moving towards Andromeda?
And that’s going to happen someday! The Andromeda galaxy is currently racing toward our Milky Way at a speed of about 70 miles (110 km) per second. Ultimately, the two galaxies will collide and merge.
How many light years away is Andromeda?
Stars are found in large groups called galaxies. A galaxy can have millions or billions of stars. The nearest large galaxy to us, Andromeda, is 2.5 million light-years away.
How fast can we travel a light-year?
Saying we were a space shuttle that travelled five miles per second, given that the speed of light travels at 186,282 miles per second, it would take about 37,200 human years to travel one light year.
How long will it take Voyager 1 to travel a light-year?
A light-year is 9.5 trillion kilometers. By division, that means it’s going to take Voyager 17,720 years to travel ONE light year. That’s 80,000 years to reach Alpha Centauri, 4.5 light years away.
How far is Earth in light years?
A light-year is a measurement of distance and not time (as the name might suggest). A light-year is the distance a beam of light travels in a single Earth year, or 6 trillion miles (9.7 trillion kilometers).
Is a black hole faster than light?
Supermassive black hole bigger than 7 billion Suns is spinning so fast that it’s close to breaking the laws of physics. Messier 87, star of the first image of the black hole , is spinning between 2.4 to 6.3 times faster than the speed of light .
What is the fastest thing in the universe?
In modern physics, light is regarded as the fastest thing in the universe, and its velocity in empty space as a fundamental constant of nature.
Is hyperspace possible?
While hyperspace is not a current form of space travel, there is ongoing research to determine how viable it is — and what the experience would be like. In 2013, a group of physics students corrected the view of what happens when spaceships fly at the speed of light.
What will happen to our galaxy in 4 billion years?
In roughly 4.5 billion years’ time the Milky Way will smash into the rapidly approaching Andromeda Galaxy, and astronomers are still attempting to predict what it will be like when the two galaxies collide. That a collision between our galaxy and the Andromeda Galaxy is inevitable has been known for a little while.
Can the earth survive Andromeda collision?
Excluding planetary engineering, by the time the two galaxies collide, the surface of the Earth will have already become far too hot for liquid water to exist, ending all terrestrial life; that is currently estimated to occur in about 3.75 billion years due to gradually increasing luminosity of the Sun (it will have.
Has the Milky Way ever collided with another galaxy?
At least a dozen times over the last 12 billion years, the Milky Way collided with a neighboring galaxy and devoured it, swallowing up that neighbor’s stars and mixing them into an ever-growing stew of pilfered suns.
