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 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!Oct 22, 2020.
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.
What happens if we enter another galaxy?
When the galaxies collide, it causes vast clouds of hydrogen to collect and become compressed, which can trigger a series of gravitational collapses. A galaxy collision also causes a galaxy to age prematurely, since much of its gas is converted into stars.
Will we ever travel faster than light?
General Relativity states that space and time are fused and that nothing can travel faster than the speed of light. General relativity also describes how mass and energy warp spacetime – hefty objects like stars and black holes curve spacetime around them.
Can light travel forever?
Light is made up of particles called photons that travel like waves. Unless they interact with other particles (objects), there is nothing to stop them. If it is infinite, the light would travel forever.
Will humans ever leave the Milky Way?
Our Galaxy, the Milky Way, is a disk of stars about 100,000 light-years across, and about 1,000 light-years thick. 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.
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.
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.
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 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 we can travel in space?
We believe in the free flow of information The closest star to Earth is Proxima Centauri. It is about 4.25 light-years away, or about 25 trillion miles (40 trillion km). The fastest ever spacecraft, the now- in-space Parker Solar Probe will reach a top speed of 450,000 mph.
Can light be destroyed?
6. Photons are easily created and destroyed. Unlike matter, all sorts of things can make or destroy photons. If you’re reading this on a computer screen, the backlight is making photons that travel to your eye, where they are absorbed—and destroyed.
How far can light travel in one year?
A light-year is the distance that light can travel in one year — about 6 trillion miles (10 trillion kilometers). It’s one way that astronomers and physicists measure immense distances across our universe. Light travels from the moon to our eyes in about 1 second, which means the moon is about 1 light-second away.
Does light take up space?
Yes, light waves can “collide” and interact with each other (rarely), but that itself doesn’t imply that they need to occupy space. It’s not even entirely clear what it means for a subatomic particle to occupy space.
Will the Milky Way collide with Andromeda?
Previous simulations have suggested that Andromeda and the Milky Way are scheduled for a head-on collision in about 4 billion to 5 billion years. But the new study estimates that the two star groups will swoop closely past each other about 4.3 billion years from now and then fully merge about 6 billion years later.
How long would it take to get out of the Milky Way in years?
At 17.3 km/s, it would take Voyager over1,700,000,000 years to traverse the entire length of the Milky Way. Even traveling at the speed of light, it would take nearly a hundred thousand years!Oct 22, 2020.
Will Voyager 1 ever stop?
How long can Voyager 1 and 2 continue to function? Voyager 1 is expected to keep its current suite of science instruments on through 2021. Voyager 2 is expected to keep its current suite of science instruments on through 2020.
