# Question: Can Anything Travel At The Speed Of Light?

## Why cant you travel at the speed of light?

According to the laws of physics, as we approach light speed, we have to provide more and more energy to make an object move.

In order to reach the speed of light, you’d need an infinite amount of energy, and that’s impossible!.

## What is the fastest thing in the universe?

And, while light is still by far the fastest thing in the universe, moving at a staggering speed of 299791.82 km/h, the following list contains some of the other closest things to reach that title of “World’s Fastest.”

## What is the 30 30 rule for lightning?

Use the 30/30 rule! Go indoors if you see lightning and can’t count to 30 before hearing thunder. Stay inside for 30 minutes after hearing the last clap of thunder.

## Is lightning hotter than the sun?

Lightning is four times hotter than the sun. … A return stroke of lightning, that is, a bolt shooting up from the ground to a cloud (after a stream of electricity came downward from a cloud) can peak at 50,000 degrees Fahrenheit (F). The surface of the sun is around 11,000 degrees F.

## What does being struck by lightning feel like?

A jolting, excruciating pain. “My whole body was just stopped—I couldn’t move any more,” Justin recalls. “The pain was … I can’t explain the pain except to say if you’ve ever put your finger in a light socket as a kid, multiply that feeling by a gazillion throughout your entire body.

## How fast is the speed of light in Mach?

Since sound needs a medium to travel I can only assume you mean in atmosphere. The speed of sound in air is 343 m/s (Mach 1) the speed of light in atmosphere approximates at 3×10^8 m/s. So to answer your question the speed of light is approximately Mach 874,635.6.

## Can anything travel faster than the speed of light?

There is no limit to how fast the universe can expand, says physicist Charles Bennett of Johns Hopkins University. Einstein’s theory that nothing can travel faster than the speed of light in a vacuum still holds true, because space itself is stretching, and space is nothing.

## Can matter travel at the speed of light?

All massless particles travel at the speed of light, including the photon, gluon and gravitational… … Moreover, anything that’s made of matter can only approach, but never reach, the speed of light. If you don’t have mass, you must move at the speed of light; if you do have mass, you can never reach it.

## How fast is the speed of dark?

54 meters per secondThis mysterious energy makes up 80 percent of all matter in the universe. In a 2013 study, scientists determined that dark matter should have a speed of 54 meters per second, or 177 feet — slow compared to the speed of light [source: Armendariz-Picon and Neelakanta].

## What happens to time at the speed of light?

Einstein’s theory of special relativity says that time slows down or speeds up depending on how fast you move relative to something else. Approaching the speed of light, a person inside a spaceship would age much slower than his twin at home. Also, under Einstein’s theory of general relativity, gravity can bend time.

## How fast is a lightning bolt?

about 3,700 miles per secondIts can depend on air conditions, but the typical lightning bolt moves at 224,000 mph — or about 3,700 miles per second. However, the light you see from the lightning obviously travels at the speed of light, which is roughly 670 million mph, or 186,000 miles per second.

## What happens if we travel faster than light?

But if something can travel faster than light, it can travel backward in time, according to the theory. In this case, an “effect” could travel back to a point before its “cause” had occurred — for instance, a baby swinging before he gets a push.

## How fast does light travel in a vacuum?

670,616,629 miles per hourThe theory of special relativity showed that particles of light, photons, travel through a vacuum at a constant pace of 670,616,629 miles per hour — a speed that’s immensely difficult to achieve and impossible to surpass in that environment.
