# Quick Answer: Will We Ever Travel Faster Than Light?

## How many G’s can kill you?

The body is designed to pump blood upward, but negative gs force more of the blood to the head, causing vessels to burst in the eyes — a condition called “red out” — and, eventually, the brain.

A extended force as low as negative 3 gs can prove fatal..

## How fast is 1G in mph?

about 22 mphAn acceleration of 1 G is equivalent to a speed of about 22 mph (35 km/h) per second.

## Can humans survive light speed?

So will it ever be possible for us to travel at light speed? Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no. … So, light-speed travel and faster-than-light travel are physical impossibilities, especially for anything with mass, such as spacecraft and humans.

## How fast can a spaceship go in space?

about 17,500 miles per hourA. Like any other object in low Earth orbit, a Shuttle must reach speeds of about 17,500 miles per hour (28,000 kilometers per hour) to remain in orbit.

## What is the most dangerous thing in the universe?

Supermassive black holes are strange. The biggest black hole discovered so far weighs in at 40 billion times the mass of the Sun, or 20 times the size of the solar system. Whereas the outer planets in our solar system orbit once in 250 years, this much more massive object spins once every three months.

## Can a spaceship travel faster than light?

On this scale, the distance to Alpha Centauri A would be 276 kilometers (171 miles). The fastest outward-bound spacecraft yet sent, Voyager 1, has covered 1/600 of a light-year in 30 years and is currently moving at 1/18,000 the speed of light. At this rate, a journey to Proxima Centauri would take 80,000 years.

## How fast can a human go without dying?

While the human body can withstand any constant speed—be it 20 miles per hour or 20 billion miles per hour—we can only change that rate of travel relatively slowly. Speed up or slow down too quickly and it’s lights out for you, permanently.

## What is the fastest thing in the universe?

Laser beams travel at the speed of light, more than 670 million miles per hour, making them the fastest thing in the universe.

## What is fastest cat?

Cheetah CheetahsCheetah. Cheetahs (Acinonyx jubatus) are not just the fastest cats… they’re the fastest animals on land! The latest research is revealing that it’s their extraordinary manoeuvrability that really gives them the killer edge. They can run faster, brake harder and turn quicker than any other predator on land.

## What can travel faster than light?

Albert Einstein’s special theory of relativity famously dictates that no known object can travel faster than the speed of light in vacuum, which is 299,792 km/s.

## Will we ever develop faster than light travel?

“What warp drive is doing is basically saying that there is no law of physics that says space-time itself can’t go faster than the speed of light,” says Dr Erin Macdonald, astrophysicist and science consultant for Star Trek.

## 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. … However, when we think of the phrase “time travel,” we are usually thinking of traveling faster than 1 second per second.

## Is light faster than darkness?

Most of us already know that darkness is the absence of light, and that light travels at the fastest speed possible for a physical object. … In this respect, darkness has the same speed as light.
