Do you get older 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.
If you travelled at the speed of light, how would you experience time? Travelling in space for three years at close to the speed of light would equal five years on Earth. This indicates how an astronaut might age on a long space journey.
Scientists have recently observed for the first time that, on an epigenetic level, astronauts age more slowly during long-term simulated space travel than they would have if their feet had been planted on Planet Earth.
If an object ever did reach the speed of light, its mass would become infinite. And as a result, the energy required to move the object would also become infinite: an impossibility.
Chou did the math, and it turns out that frequent fliers actually age the tiniest bit more quickly than those of us with both feet on the ground. Planes travel at high enough altitudes that the weak gravitational field speeds up the tick rate of a clock on board more than the high speeds slow it down.
Scientists estimate that the heart, blood vessels, bones, and muscle deteriorate about 10 times faster in space than in natural aging.
Light-year is the distance light travels in one year. Light zips through interstellar space at 186,000 miles (300,000 kilometers) per second and 5.88 trillion miles (9.46 trillion kilometers) per year.
The speed of light in a vacuum is an absolute cosmic speed limit. Nothing can go faster than 3.0 x 108 meters per second (that's 300,000,000 m/s or 1,080,000,000 km/h!). According to the laws of physics, as we approach light speed, we have to provide more and more energy to make an object move.
If you leave Earth at the age of 15 in a spaceship at the speed of light and spend 5 Years in space, when you get back on Earth you will be 20 years old and all your friends who were 15 when you left will be 65 years old. This phenomenon is known as "Time Dilation" in Physics.
Changes to time and distance
Perhaps one of the most famous effects of special relativity is that for a human moving near the speed of light, time slows down. In this scenario, a person moving at near light speed would age more slowly. This effect is called time dilation.
Why don't you age as fast in space?
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.
Darkness travels at the speed of light. More accurately, darkness does not exist by itself as a unique physical entity, but is simply the absence of light. Any time you block out most of the light – for instance, by cupping your hands together – you get darkness.
We can never reach the speed of light. Or, more accurately, we can never reach the speed of light in a vacuum. That is, the ultimate cosmic speed limit, of 299,792,458 m/s is unattainable for massive particles, and simultaneously is the speed that all massless particles must travel at.
No, humans cannot survive travelling at the speed of light. You see, if an object travels at the speed of light, its mass will increase exponentially! Consider this… the speed of light is 300,000 kilometers per second (186,000 miles per second) and when an object moves at this speed, its mass will become infinite.
In 2007, the retirement age for pilots in the United States was raised from 60 to 65 after medical reports concluded age had an 'insignificant impact' on performance in the co*ckpit and there were safety precautions already in place to prevent accidents in case of incapacitation.
- Oldest active pilot ever recorded: Cole Kugel.
- Age at record (2007): 105.
- Born: 1902, one year before Wright Brothers' historic flight.
- Year licensed: 1945.
- First plane: Piper Super Cruiser.
- Distance to ferry plane home: 1,250 miles.
- Technology used: Compass, road maps.
- Lifetime in-flight emergencies: 0.
There's technically no particular age limit before you can begin taking flying lessons. The main restrictions come with the pilot being at least 16 years old before being allowed to take a solo flight and 17 years old before they can obtain a private pilot's license.
Astronaut Thomas Jones said it "carries a distinct odor of ozone, a faint acrid smell…a little like gunpowder, sulfurous." Tony Antonelli, another space-walker, said space "definitely has a smell that's different than anything else." A gentleman named Don Pettit was a bit more verbose on the topic: "Each time, when I ...

The Earth is the only planet with an approximately 24-hour day.
| Planet | Length of Day |
|---|---|
| Earth | 23 hours, 56 minutes |
| Mars | 24 hours, 37 minutes |
| Jupiter | 9 hours, 55 minutes |
| Saturn | 10 hours, 33 minutes |
As for what determines a person's rate of biological aging, Milman said genes play a role. There are certain "longevity genes" that can help shield people from environmental stressors, to a degree.
Can we travel at 99 the speed of light?
To summarize, according to the immutable laws of physics (specifically, Einstein's Theory of Special Relativity), there's no way to reach or exceed the speed of light.
Sunlight travels at the speed of light. Photons emitted from the surface of the Sun need to travel across the vacuum of space to reach our eyes. The short answer is that it takes sunlight an average of 8 minutes and 20 seconds to travel from the Sun to the Earth.
So, according to de Rham, the only thing capable of traveling faster than the speed of light is, somewhat paradoxically, light itself, though only when not in the vacuum of space. Of note, regardless of the medium, light will never exceed its maximum speed of 186,282 miles per second.
Nothing can travel faster than 300,000 kilometers per second (186,000 miles per second). Only massless particles, including photons, which make up light, can travel at that speed. It's impossible to accelerate any material object up to the speed of light because it would take an infinite amount of energy to do so.
In order for you to stop time, you would have to be traveling infinitely fast. Nothing can travel faster than light (let alone infinitely fast) without gaining infinite mass and energy, according to Einstein's theory of relativity.
In short, space-time would contain the entire history of reality, with each past, present or future event occupying a clearly determined place in it, from the very beginning and for ever. The past would therefore still exist, just as the future already exists, but somewhere other than where we are now present.
In Earth's early history, a day was 23.5 hours and a year lasted 372 days.
Bottom line: The Holocene epoch, in which we currently live, has been divided into three new geological ages—the Greenlandian, Northgrippian, and Meghalayan. The most recent age, the Meghalayan, began 4,200 years ago during a worldwide megadrought.
Our current era is the Cenozoic, which is itself broken down into three periods. We live in the most recent period, the Quaternary, which is then broken down into two epochs: the current Holocene, and the previous Pleistocene, which ended 11,700 years ago.
Children perceive and lay down more memory frames or mental images per unit of time than adults, so when they remember events—that is, the passage of time—they recall more visual data. This is what causes the perception of time passing more rapidly as we age.
Do some people age faster or slower?
People really do vary in how fast they age, and the divergence starts in young adulthood, a new study suggests. The researchers found that by the tender age of 45, people with a faster pace of "biological aging" were more likely to feel, function and look far older than they actually were.
That's biological ageing at work. The study found that biological age is lower for recent periods across all age groups, but the difference varies based on age and gender. The scientists think that changes in smoking, obesity, and medication use are partly the reason.
This is called extrinsic aging. As a result, premature aging can set in long before it was expected. In other words, your biological clock is more advanced than your chronological clock. Controllable factors such as stress, smoking and sun exposure can all play a role in expediting extrinsic aging.

On the beach, half an hour was equivalent to approximately one year. Due to the rapid time change, their cells were aging rapidly. It became the reason for Agnes' death, who probably didn't die of shock but old age.
Re: do you age in the backrooms? Most likely you just age the same speed with certain exceptions(like being in levels or being a victim of entities).
No. The time-dilation effect of Einstein's relativity has nothing to do with space. The faster you're moving, the slower time goes for you. So if you were on some planet moving extremely fast through space, like in the movie Interstellar, then you could miss 7 years on Earth every hour.
Because astronauts like the ones on the International Space Station (ISS) are moving so quickly, they're also aging a bit more slowly than the rest of us. Due to a principle of physics known as time dilation, after a six-month stint on the ISS, returning astronauts are just a tiny bit younger than the rest of us.
It is by connecting to each other, and respecting our differences, contrasts, and nuances, that we make new meaning.
However, light travels at about 0.75c (75% light speed) through water. Some charged particles can move faster than 0.75c in water and therefore travel faster than light.
Is light faster than Sonic?
Despite his small appearance, Sonic the Hedgehog has a max speed of 186,000 miles per second and travels at a speed of 767 miles per hour. His light-speed shoes allow him to run faster than the speed of light and fight the evil genius who wants to use him in an experiment.
While 1% of anything doesn't sound like much, with light, that's still really fast – close to 7 million miles per hour! At 1% the speed of light, it would take a little over a second to get from Los Angeles to New York. This is more than 10,000 times faster than a commercial jet.
The three-crew Apollo 10 spacecraft in 1969 reached 39,897 km/h, significantly faster than an average bullet (2,736 km/h). Perhaps Yeager will have the last, fast laugh when someday, someone even Yeagerer will break the speed of light (1,079,252,848.8 km/h).
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.
Even though the force of gravity is still very much in effect, astronauts in orbit do not feel it because they're in a constant free fall.
Time travel is probably impossible. Even if it were possible, Hawking and others have argued that you could never travel back before the moment your time machine was built.
10G is ten times the acceleration due to gravity, which would be 320 ft/sec/sec. In simple words, this would mean, starting from zero, you would increase your speed to 320 ft/sec by the end of the first second.
Proxima Centauri is 4.2 light-years from Earth, a distance that would take about 6,300 years to travel using current technology. Such a trip would take many generations.
Exposure to light is a top cause of premature aging: Sun exposure causes many skin problems. Ultraviolet (UV) light and exposure to sunlight age your skin more quickly than it would age naturally. The result is called photoaging, and it's responsible for 90% of visible changes to your skin.
From getting enough physical activity to limiting alcohol and stress, these habits reduce the risk of chronic disease and slow the aging process – helping you look and feel your best for years to come.
How long would it take to travel 100 trillion light-years?
Some galaxies will have fallen over the cosmic horizon, where no amount of time would ever let you reach them. If you wanted to travel 100 trillion light years away, you could make the journey in 62 years.
In Star Trek: Voyager, it is stated that it will take 75 years to travel 70,000 light years to reach Federation space. It is stated that the Voyager can sustain a maximum crusing speed of warp 9.975.
