What happens if a needle accidentally hit the water at the speed of light?
That is a question many scientists have sought to answer for years. In Physics it is often called “light speed” and in pure hypothetical physics it is called “time”. In pure theoretical physics time does not pass, only as energy jumps from point A to point B.
In real life, how long does it take light to travel through a distance? It varies depending on the diameter of the needle, the subject of the needle, the distance from the source, etc. How long it takes for the same needle to bounce once on the ocean floor versus bouncing off each time and traveling in the opposite direction is also an interesting question. It seems that the bounce-back effect of a needle traveling at the speed of light must occur in the real ocean.
Is it possible to test this question? If a needle strikes the ocean at the rate of light, it would take a very long time indeed for the signal generated by the motion of the needle to reach Earth. As it happens, scientists are already doing experiments to see if this is possible. They have built special tanks which allow different sized needles to be passed through, then they attached time monitors to them. At regular intervals they can watch what happens to the samples of fluid contained inside these tanks.
As might be expected, if a needle strikes the ocean at the speed of light, there will be very little or no change in the fluid sample tested. The reason for this is that the molecules in this fluid are too large to become affected by the passage of the needle’s movement at the speed of light. So it looks as if what people mean when they ask what happens if a needle hits the ocean at the speed of light is actually not possible.
However, there have been studies that suggest that if a needle happened to strike the ocean at such a speed. Then it could cause tsunamis as it could generate enough force to even evaporate the water in the surrounding area. This is just measuring one needle with the speed of 99.999 percent the level of the speed of light. Which would be even more surprising when measured with 100 needles. As this amount has been said to create enough force to create a Saturn like environment. Pretty much changing the entire climate of the planet in an end game like scenario.
This is just based off of calculations as nothing has ever been able to match the speed of light. But, in combination with the physics of the planet and such a thing moving at that speed from space. The math states this could be the outcome. Let’s say it happened on a lower scale at a less distance, what would happen then?
The best revelation on what happens if a needle hit the ocean at the speed of light is to think of the ripples in the ocean bed as being more like pebbles rolling down a beach. When the ripples get large, they look like waves. If you stand on one of these waves, it will feel a bit like a pebble hitting you in the foot, except it will feel much faster. Think of the particle as being traveling along a similarly shaped wave.
And that is the way it would behave when it comes up against something like this moving at the speed of light.
