Is it Possible to Travel at the Speed of Light?

Since the first episode of "Star Trek" was broadcasted in 1966, human thoughts always had problems; fans, children and scientists are the same. For some people this is just a fantasy of fantasy thought but for others the goals and ideas pursued may not be taken so far. If so, why do humans try this method? If not, there are some restrictions on the movement at light speed, researchers are trying to solve them.

You heard already that the speed of light is the fastest speed allowed by physics, but only when the light moves in a vacuum it can reach its maximum speed - just like the universe. As long as the light passes through the transparent material, its speed will be slow. Although not mentioned in detail, air slows down the air, glass, diamonds, water decelerate it. In addition, each time a ray passes from one medium to another at an oblique angle, its direction changes. It is the same as the car's wheel hits the soft shoulder and the car is pulled away from the road. Is the same. The lens is designed carefully so that the light passing through the center does not change, but the light passing through the part between the center and the end is systematically curved and focused.

This is a method that is smaller than the speed of light. Therefore, the speed limit of a car running on the most likely roller coaster on Earth is not the speed of light, but the escape speed of the earth. Therefore, the speed set for the roller coaster must be lower than the escape speed. But for fun, let's see what happens if you pass the escape rate itself to the formula. Oh, this is very interesting - it's a negative range! How is this possible? Is our roller coaster ring underground? Well, it is not exactly. One of the things I forgot to talk about universal law of gravity: it assumes that all qualities are point quality. In other words, when we use the Earth for computation, we assume that its overall mass is concentrated in one point in space.
