Do you age if you travel at the speed of light?
That depends on how fast you’re traveling.
Thanks to Einstein, we know that the faster you go, the slower time passes–so a very fast spaceship is a time machine to the future.
Five years on a ship traveling at 99 percent the speed of light (2.5 years out and 2.5 years back) corresponds to roughly 36 years on Earth..
Can time be stopped?
The simple answer is, “Yes, it is possible to stop time. All you need to do is travel at light speed.” … We know that an object, or a light beam’s, speed measures the distance traversed over time.
What would happen if time stopped forever?
In zero seconds, light travels zero meters. If time were stopped zero seconds would be passing, and thus the speed of light would be zero. … Nothing can travel faster than light (let alone infinitely fast) without gaining infinite mass and energy, according to Einstein’s theory of relativity.
Do you age faster or slower in space?
With current technology severely limiting the velocity of space travel, however, the differences experienced in practice are minuscule: after 6 months on the International Space Station (ISS), orbiting Earth at a speed of about 7,700 m/s, an astronaut would have aged about 0.005 seconds less than those on Earth.
Does time dilation affect aging?
So depending on our position and speed, time can appear to move faster or slower to us relative to others in a different part of space-time. And for astronauts on the International Space Station, that means they get to age just a tiny bit slower than people on Earth. That’s because of time-dilation effects.
At what speed does time stop?
In the limit that its speed approaches the speed of light in vacuum, its space shortens completely down to zero width and its time slows down to a dead stop. Some people interpret this mathematical limit to mean that light, which obviously moves at the speed of light, experiences no time because time is frozen.
Can time machine be made?
Travelling in time might sound like a flight of fancy, but some physicists think it might really be possible. BBC Horizon looked at some of the most promising ideas for turning this staple of science fiction into reality. Ron Mallett has a dream: He wants to travel in time.
Can you live in space forever?
It protects the astronauts from the cold of space, gives them air to breathe, and protects them from all that nasty radiation. … Again, though, it’s not safe for people to live their forever, and being in space for a long time isn’t good for your body.
Can you get drunk in space?
“Alcohol is not permitted onboard the International Space Station for consumption,” says Daniel G Huot, spokesperson for Nasa’s Johnson Space Center. “Use of alcohol and other volatile compounds are controlled on ISS due to impacts their compounds can have on the station’s water recovery system.”
Do astronauts shower?
The astronauts wipe their body clean by using a wet towel, and wash their hair by using waterless shampoo. Since water does not flow in a zero-gravity environment, the astronauts cannot wash their hands under a faucet as you do on Earth. So, there are no sinks or showers inside the space shuttle.
Do you age faster or slower on Mars?
1 Answer. Short answer: Most likely not, but we don’t really know. There are theories about how gravity affects the physiology of our body, and we know what aspects get affected by lack of gravity. The overwhelming majority of effects noted due to low gravity are negative.
Could a human survive light speed?
“There is no real practical limit to how fast we can travel, other than the speed of light,” says Bray. Light zips along at about a billion kilometres per hour. … Therefore, humans should – in theory – be able to travel at rates just short of the “Universe’s speed limit”: the speed of light.
Why do we age slower in space?
This form of time dilation is also real, and it’s because in Einstein’s theory of general relativity, gravity can bend spacetime, and therefore time itself. The closer the clock is to the source of gravitation, the slower time passes; the farther away the clock is from gravity, the faster time will pass.

Who is the oldest planet?
PSR B12620-26 b The exoplanet known as PSR B12620-26 b is the oldest known planet in the universe, with an estimated age of about 13 billion years.
