Is it possible to move an object at the speed of light?

Get to the speed of light (not really possible, but imagine if you could for a moment) and the object’s length would shrink to zero. This explains why nothing can travel faster than light – at or near light speed, any extra energy you put into an object does not make it move faster but just increases its mass.

How long would it take for a human to accelerate to the speed of light?

It would take 353,7 days of constant 1G (9,81 m/s^2) acceleration to reach the speed of light. In that time you would travel 4,58 billion Km. But the human body can take more than 1G, not sure what’s the limit, and for how long.

What would happen if you accelerated at the speed of light?

Because of this equivalence, the energy an object has due to its motion will increase its mass. In other words, the faster an object moves, the greater its mass. But if it moves at 90 percent the speed of light, its mass will double. As an object approaches the speed of light, its mass rises precipitously.

Is it possible to accelerate a massive object to the speed of light in a real situation?

No, it is not possible. Accelerating a massive object to the speed of light would require infinite energy. Objects may be accelerated up to but not beyond the speed of light because it is the ultimate speed limit.

Why can’t we exceed speed of light?

The speed of light in a vacuum is an absolute cosmic speed limit. 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!

Could the human body survive light speed?

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.

Why is it not possible to accelerate an object with mass to the speed of light?

As an object approaches the speed of light, its mass approaches infinity (see diagram). Because masses approach infinity with increasing speed, it is impossible to accelerate a material object to (or past) the speed of light. To do so would require an infinite force.

How much mass does it take to accelerate to speed of light?

This means that the closer the object is to the speed of light, the closer it is to having infinite mass. Therefore it will take an infinite amount of mass to accelerate an object with any mass to the speed of light.

Is it possible to move faster than the speed of light?

Updated March 10, 2018. One commonly known fact in physics is that you cannot move faster than the speed of light. While that’s basically true, it’s also an over-simplification. Under the theory of relativity, there are actually three ways that objects can move: At the speed of light. Slower than the speed of light.

Can a laser pointer travel faster than the speed of light?

If you point a laser pointer at the top of a distant object that’s 300,000,000 meters tall and then you rotate the laser pointer so it points at the bottom of the object in one second, wouldn’t the dot travel faster than the speed of light?

What are three ways to travel at the speed of light?

Three Ways to Travel at (Nearly) the Speed of Light. 1 1) Electromagnetic Fields. Most of the processes that accelerate particles to relativistic speeds work with electromagnetic fields — the same force 2 2) Magnetic Explosions. 3 3) Wave-Particle Interactions.
