The person traveling at the speed of light would experience a slowing of time. For that person, time would move slower than for someone who is not moving. Also, their field of vision would change drastically. The world would appear through a tunnel-shaped window in front of the aircraft in which they are traveling.

No, it is not possible for a human to survive travelling at the speed of light. Others have pointed out that it’s impossible to reach the speed of light, so they’re talking about the limits as you approach the speed of light. But at the speed of light, you experience singularity-like conditions.

Changes in speed are expressed in multiples of gravitational acceleration, or ‘G’. Most of us can withstand up to 4-6G. Fighter pilots can manage up to about 9G for a second or two. But sustained G-forces of even 6G would be fatal.

22 miles per hour

Each additional +Gz (blood flows from the head to the feet) that a person experiences multiplies that requirement: The body has to muster double that at 2g, triple that at 3g, and so on until they hit around 4 or 5 G’s, at which point most folks will pass out due to oxygen starvation because all the blood stays in …

— Steve in Davis, Calif. So far, the fastest anyone has run is about 27½ miles per hour, a speed reached (briefly) by sprinter Usain Bolt just after the midpoint of his world-record 100-meter dash in 2009. This speed limit probably is not imposed by the strength of our bones and tendons.

about 22 mph

Our universe works similarly, but we’re embedded on a three-dimensional space instead of a two-dimensional one. There is no ‘still’ that is not relative to some other object. So yes, you can be still with respect to one object, but you’ll be moving with respect to every other object.

you will need to constantly fire the engine to hold youself in position (this is possible, until you run out of fuel). Yes, it is possible to fire the engine and lift off earth into space, and then fire in the opposite direction to earths movement until you are still, relative to the sun.

No. Even if you manage to define a good universal reference frame, you still can never fully stop. Even if you are just “in space” you are already somewhere, which limits, by the uncertainty principle, the precision with which you can determin your momentum, thus you can never fully be at rest!

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.

Left unchecked, the inflated bubbles will cause significant tissue damage, but other things will kill you first. In space there’s nothing to insulate you, so eventually you’ll freeze to death. There’s no air in space (it’s kind of part of the definition), which means there’s no oxygen. But your blood doesn’t know that.

Near a black hole, the slowing of time is extreme. From the viewpoint of an observer outside the black hole, time stops. Inside the black hole, the flow of time itself draws falling objects into the center of the black hole. No force in the universe can stop this fall, any more than we can stop the flow of time.

There Are at Least 4 Ways a Black Hole Could Kill You

• Spaghettification. Black holes form when a massive object, like a star, collapses and squeezes all of its mass into an impossibly small point with infinite density, known as a singularity.
• Fried by Accretion Disk.
• Zapped by Plasma Jet.
• Incinerated by Firewall.

He has enough power to create life, or his own universe, for that matter. P.S. even the regular Superman can survive a black hole. Since nothing can escape a black hole after touching the event horizon,not even light Superman have to fly with a speed greater than that of light than he may have a chance.

The Sun. Our sun is one of the largest and heaviest objects in the universe, weighing in at 1.989 x 1030 kg. To get an idea of how big this is, this is 330,000 times the weight (mass) of Earth. In our solar system, the sun is by far the heaviest object.

Graphene Aerogel, world’s lightest substance.

Researchers from us-based Lawrence Livermore National Laboratory (llnl) have discovered that osmium, a metal, is harder than diamond. It withstands compression better than any other material. It is usually found that materials with higher bulk modulus are also hard.

The first chemical element with the lowest density is Hydrogen and the highest density is Osmium.

A material with more matter, or stuff packed into a given space, has a higher density than a material with less matter packed into the same space.
