# Readers ask: You Are Standing By The Side Of The Road When A Car Traveling At A Speed?

## What would happen if you were in a car traveling in space at the speed of light and you turned on the headlights of the car what would happen?

If you drove a car close to the speed of light relative to the ground (neglect air effects) and turn on the headlights, light would leave your headlights at speed c the way it always does. To you in the speeding car, the light would be traveling away at speed c. The moving car actually gets squashed front to back.

## What happens to light when traveling at the speed of light?

According to Einstein’s general theory of relativity, as an object moves faster, its mass increases, while its length contracts. At the speed of light, such an object has an infinite mass, while its length is 0 — an impossibility. Thus, no object can reach the speed of light, the theory goes.

## What happens if you travel at the speed of light and turn on a flashlight?

The short answer is that light coming out of your torch instantly reaches the speed of light. Light can only ever travel at the speed of light — 300,000,000 metres per second in a vacuum, and a bit slower in air because it bumps into molecules. So why is light only allowed to travel at that one speed?

## When can a person move at the speed of a car?

Some states allow drivers to speed when passing slow vehicles. But, how fast can you go over the speed limit? It varies, but sometimes, when overtaking another car, you are allowed to exceed the speed limit by 10-15 mph. Typically, this applies to two-lane highways where the posted speed limit is 55 mph or higher.

## Does time stop at the speed of light?

The simple answer is, ” Yes, it is possible to stop time. All you need to do is travel at light speed.” Special Relativity pertains specifically to light. The fundamental tenet is that light speed is constant in all inertial reference frames, hence the denotation of “c” in reference to light.

## Can anything 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.

## Can humans travel 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.

## What is the fastest thing in the universe?

In modern physics, light is regarded as the fastest thing in the universe, and its velocity in empty space as a fundamental constant of nature.

## Is light faster than darkness?

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.

## Is speed of light relative?

The speed of light is constant relative to everything. Light differs only in that everyone perceives light to have the same relative speed; 299,792,458m/s in a vacuum.

## What’s faster the speed of light?

The speed of light, the fastest moving thing we know of, is 299,792,458 meters per second in a vacuum. That’s over 186,000 miles per second. But physicists didn’t always know light traveled at a finite speed. Traveling at over 186,000 miles per second in a vacuum, light is the fastest-moving thing we know of.

## Is warp drive faster than light?

A spacecraft equipped with a warp drive may travel at speeds greater than that of light by many orders of magnitude. In contrast to hyperspace, spacecraft at warp velocity would continue to interact with objects in “normal space”.

## When you are in a vehicle going 55 mph How fast is your body moving?

At 55 mph, your vehicle is traveling at about 80 feet per second.

## Does a photon experience space?

Yet despite this incredible journey, the photon itself experiences none of what we know as time: it simply is emitted and then instantaneously is absorbed, experiencing the entirety of its travels through space in literally no time. Given everything that we know, a photon never ages in any way at all.

## Is there a vehicle that can travel the speed of light?

The good news is that cars do not travel at the speed of light. Only massless particles, like photons, may travel at the speed of light, and in fact massless particles may travel at no other speed.
