Why can an object not reach 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!
Why is it impossible for any object with mass to move as fast as the speed of light?
The length of moving objects also shrink in the direction in which they move. 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.
Can something fall at the speed of light?
No. Any object during free fall in any medium can’t be reached to the velocity of light. During the free fall, every object achieves Terminal Velocity which doesn’t increase further due to gravitational force and is much less than the velocity of light.
What happens if you travel at light speed into a black hole?
A black hole is a region of space that is so warped that not even light can escape. Nothing can go faster than the speed of light, so nothing can escape a black hole. If light could go faster than the “speed of light”, then it could escape the event horizon, and would no longer qualify as a black hole.
Can human travel at speed of light?
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 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”.
Does gravity accelerate faster than light?
Kopeikin and Fomalont concluded that the speed of gravity is between 0.8 and 1.2 times the speed of light, which would be fully consistent with the theoretical prediction of general relativity that the speed of gravity is exactly the same as the speed of light.
Could I become a black hole?
In theory, any mass can be compressed sufficiently to form a black hole. The only requirement is that its physical size is less than the Schwarzschild radius. For example, our Sun would become a black hole if its mass was contained within a sphere about 2.5 km across.
Can light be accelerated by gravity?
Yes, Light can be either accelerated or decelerated by motion of the Vacuum medium. According to general relativity theory, light too is affected by gravitational force. Thus, when a light passes nearby a black hole (which is super dense and has a strong gravitional field nearby it), light bends towards the black hole.
