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.
Will interstellar travel ever be possible?
Because of the vastness of those distances, practical interstellar travel based on known physics would need to occur at a high percentage of the speed of light; even so, travel times would be long, at least decades and perhaps millennia or longer.
How many years will it take to get 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
Is Cryosleep possible?
There are many instances of animal and human bodies found in the ice, frozen, yet preserved and not damaged by the extreme temperature. This makes the concept of a ‘cryosleep’ sound doable. The first person to be cryopreserved was Dr. James Bedford in 1967.
Can we see Andromeda from Earth?
With an apparent magnitude of 3.4, the Andromeda Galaxy is among the brightest of the Messier objects, making it visible to the naked eye from Earth on moonless nights, even when viewed from areas with moderate light pollution.
Do you age in Cryosleep?
Cryosleep is “sleeping” or “hibernating” for long periods of time in a controlled environment. Cryosleep is featured in the film Avatar, where Jake Sully and other passengers cryosleep while they travel to Pandora. While cryosleeping, or “in cryo”, a person does not age.
Can we ever reach Andromeda?
Highly unlikely. Andromeda is 2.5 million light years away. Even if we managed to build a ship that could go 99.9999999999999% the speed of light, it’ll take 2.5 million years to get there.
Is the universe infinite?
Does the cosmos go on forever, or is outer space finite? The observable universe is still huge, but it has limits. That’s because we know the universe isn’t infinitely old — we know the Big Bang occurred some 13.8 billion years ago. That means that light has had “only” 13.8 billion years to travel.
Will humans 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.
Can neutrinos travel faster than light?
Scientists working at the facility have discovered that subatomic neutrino particles may have traveled through the 17-mile (27 kilometers) long particle collider at faster than the speed of light. The only thing is… nothing can travel faster than the speed of light.
Is deep sleep in space possible?
So while it might be possible to induce humans into deep sleep by cooling the body, Heller said, a months-long spaceflight under such conditions is likely to be too damaging. “I think it’s probably not doable,” he said.
Can humans travel to other dimensions?
We have a universe with three dimensions and if you include space-time, four. So in Stranger Things, characters don’t travel to another dimension but rather another version of Earth in a parallel universe. Hypothetically, this holds true. If space-time goes on forever, it only makes sense that it must repeat itself.
Is Lightspeed travel possible?
Light can travel at about 300,000 kilometers in one second. Physicist Albert Einstein’s famous theory of relativity suggests that it is not possible to travel faster than light. They call for “hypothetical particles” and states of matter with unusual physical properties to permit faster-than-light travel.
How long would it take to travel to Andromeda?
How long would it take to get to the Andromeda Galaxy? Forget it! Although 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.
How fast can a human go without dying?
“Our bodies are surprisingly resilient in many situations, but rapid acceleration is not one of them. While the human body can withstand any constant speed—be it 20 miles per hour .”
What is outside the universe?
Outside the bounds of our universe may lie a “super” universe. Space outside space that extends infinitely into what our little bubble of a universe may expand into forever. Lying hundreds of billions of light years from us could be other island universes much like our own.
Is a wormhole possible?
Wormholes, like black holes, appear in the equations of Albert Einstein’s general theory of relativity, published in 1916. “From a mathematical perspective such a shortcut would be possible, but no one has ever observed a real wormhole,” the physicist explains. Moreover, such a wormhole would be unstable.
What happens if you go into 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.
Is it possible to travel back in time?
The Short Answer: Although humans can’t hop into a time machine and go back in time, we do know that clocks on airplanes and satellites travel at a different speed than those on Earth. NASA’s space telescopes also give us a way to look back in time. Telescopes help us see stars and galaxies that are very far away.
Does Cryosleep stop aging?
Cryo sleep essentially slows the aging process down to the point where any change is negligible by reducing the body’s metabolism.
What is the fastest we can travel in space?
But Einstein showed that the universe does, in fact, have a speed limit: the speed of light in a vacuum (that is, empty space). Nothing can travel faster than 300,000 kilometers per second (186,000 miles per second).
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.
