# Quick Answer: Why Can T We Travel Faster Than Light?

## Can you travel faster than the speed of 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. Unlike objects within space–time, space–time itself can bend, expand or warp at any speed.

## What happens if a human travels faster than the speed of light?

If an object tries to travel 186,000 miles per second, its mass becomes infinite, and so does the energy required to move it. For this reason, no normal object can travel as fast or faster than the speed of light.

## 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.

## How fast is the speed of dark?

Is there such a thing as the speed of dark? 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.

## 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.

## Is it possible to travel back in time?

General relativity. Time travel to the past is theoretically possible in certain general relativity spacetime geometries that permit traveling faster than the speed of light, such as cosmic strings, traversable wormholes, and Alcubierre drives.

## Is there a particle faster than light?

A tachyon (/ˈtækiɒn/) or tachyonic particle is a hypothetical particle that always travels faster than light. Tachyons would also exhibit the unusual property of increasing in speed as their energy decreases, and would require infinite energy to slow down to the speed of light.

## Is a black hole faster than light?

Supermassive black hole bigger than 7 billion Suns is spinning so fast that it’s close to breaking the laws of physics. Messier 87, star of the first image of the black hole, is spinning between 2.4 to 6.3 times faster than the speed of light.

## What’s the fastest thing humans have made?

Fastest human-made object: 244,255 mph (393,044 km/h). Closest spacecraft to the sun: 11.6 million miles (18.6 million kilometers).

## Who created darkness?

First we ask, “Where does darkness come from?” God created darkness. Isaiah 45:7 says, “I form the light and create darkness: I make peace and create evil: I the Lord do all these things.” The word creates the means to form, fashion, or to permit.

## Why is darkness black?

Color paints are mixed together to create darkness, because each color absorbs certain frequencies of light. Theoretically, mixing together the three primary colors, or the three secondary colors, will absorb all visible light and create black.

## Can dark matter travel faster than light?

Dark matter interacts by gravitation, so it has nonzero mass. Therefore it can’t travel at, and nothing does travel faster than the speed of light.
