Unfortunately,
we’re unlikely to ever make contact with life in other galaxies
. Travel by spaceship to our closest intergalactic neighbor, the Canis Major Dwarf, would take almost 750,000,000 years with current technology. Even a radio signal, which moves at close to the speed of light, would take 25,000 years.
Will interstellar travel ever be possible?
As of 2022, five uncrewed spacecraft, all launched and operated by the United States, have achieved the escape velocity required to leave the Solar System, as part of missions to explore parts of the outer system. They will therefore continue to travel through interstellar space indefinitely.
What happens if we go to another galaxy?
The Milky Way Galaxy — home to planet Earth — is on a collision course with another interstellar body, a spiral of stars known as the Large Magellanic Cloud (LMC). When the two finally meet
it will not only create a massive black hole, but it may also fling our solar system thousands of lightyears away
.
How many years would it take to reach 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!
Will humans ever leave the Milky Way?
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.
Is time Travelling possible?
In Summary:
Yes, time travel is indeed a real thing
. But it’s not quite what you’ve probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second.
Is warp engine possible?
“
None of the physically conceivable warp drives can accelerate to speeds faster than light
,” Bobrick says. That is because you would require matter capable of being ejected at speeds faster than light—but no known particles can travel that fast.
Is Lightspeed travel possible?
Based on our current understanding of physics and the limits of the natural world,
the answer, sadly, is no
. According to Albert Einstein’s theory of special relativity, summarized by the famous equation E=mc
2
, the speed of light (c) is something like a cosmic speed limit that cannot be surpassed.
How fast can a human go without dying?
This is a well documented field, and the average maximum survivable g-force is about
16g (157m/s) sustained for 1 minute
. However this limit depends on the individual, whether the acceleration is applied to one’s entire body or just individual parts and the time in which the acceleration is endured over.
How far can we go in space?
That
~18 billion light-year
figure is the limit of the reachable Universe, set by the expansion of the Universe and the effects of dark energy.
Can we reach Andromeda Galaxy?
With present technology it is impossible
.to go to another galaxy.
What’s inside a black hole?
At the center of a black hole, it is often postulated there is something called a
gravitational singularity, or singularity
. This is where gravity and density are infinite and space-time extends into infinity. Just what the physics is like at this point in the black hole no one can say for sure.
How far away are we from the next galaxy?
At
2.5 million light years
from Earth, it is the nearest galaxy to our Milky Way.” Thank you, Randy!
What planets are in Andromeda?
Does the Andromeda Galaxy have planets? There is currently only one very strong candidate planet in the Andromeda Galaxy, temporarily named
PA-99-N2
. It was detected because of a microlensing event in 1999.
How far is a black hole from Earth?
In 2020, a team of astronomers with the European Southern Observatory (ESO) discovered the closest black hole to Earth in the HR 6819 system, just
1,000 light-years
away, only to have other scientists dispute the findings.
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. The radioisotope thermoelectric generator on each spacecraft puts out 4 watts less each year.
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 …
What do scientists think will eventually happen to the two galaxies?
Milky Way and Andromeda merger has begun
But one day, far in the future, Andromeda will be bright in our sky, growing larger and larger … as it gets closer and closer to us. And even though the two galaxies are still 2.5 million light-years apart,
the eventual merger of our two galaxies has, in fact, already begun
.
Can a wormhole exist?
Einstein’s theory of general relativity mathematically predicts the existence of wormholes, but
none have been discovered to date
. A negative mass wormhole might be spotted by the way its gravity affects light that passes by.
Has a time machine been invented?
In fact,
a time machine has already been built
. Scientists, however, are still working on how to make it as efficient as possible, like in the Back to the Future movies.
Where does space end?
It extends
about 20 miles (32 kilometers) above the Earth
. Floating around the atmosphere is a mixture of molecules – tiny bits of air so small you take in billions of them every time you breathe.
Is NASA building a warp drive?
According to Popular Mechanics, the NASA warp drive will expend a massive amount of energy that will “warp” (contract and twist) space time behind the spacecraft, which will create a space time “bubble.” This bubble, which will be created around the ship and curved behind it, will theoretically reduce the distance that …
Is NASA working on a warp drive?
DARPA and NASA Scientists Accidentally Create Warp Bubble for Interstellar Travel.
A Defense Advanced Research Projects Agency-funded research project at NASA’s Johnson Space Center may have accidentally discovered how to build a warp drive engine
. The scientists published their findings in July.
Are scientists working on a warp drive?
Seriously. Humans are one step closer to traveling at faster-than-light speeds. A new paper proposes a fully physically realized model for warp drive.
Is bending space possible?
“We know that
space can be bent
. If space can be bent by, say, gravity, then spacetime can be bent,” Beacham said. To clarify, space is the three-dimensional body in which all things in the universe move. Spacetime, however, is the combined concepts of space and time into a four-dimensional continuum.
What is the fastest we will ever be able to travel?
The fastest ever spacecraft, the now- in-space Parker Solar Probe will reach a top speed of
450,000 mph
.
