A method that can easily exceed the speed of light in the backyard of the house is open

Einstein'sSpecial relativitySome people think that "in this universe it can not move faster than light". However, a movie explaining "How to Overcome the Light Speed" as "We can easily realize the speed exceeding the speed of light in the backyard" is on YouTube.

There may be many people remembering Einstein's special relativity theory in the form of "There is nothing that moves faster than light in the universe". But that is a mistake.


Einstein stated only that "light moves at the same speed from all reference coordinate systems", and it is guided by this that "objects with mass can not move faster than light".


However, this does not necessarily indicate the limit of speed in the universe.


Let's get out to the backyard for the time being to exceed the speed of light.


Andlaser pointerHold on to the moon with you.


Then twist the wrist holding the laser pointer quickly and shake the laser that irradiated the moon to the left.


Then, the speed at which the laser point moves from the end of the moon to the edge (about 3.5 million meters) is how much 0.0005 seconds.


How much this is 20 times the speed of light. In this way, we can easily move the laser point with speed that is beyond the speed of light.


If you think that "Why is this possible? There should not be anything that can move beyond the speed of light?", It seems that your head may overheat. Change the viewpoint here and think about how fast you can move pixels on the PC screen.


The answer is simple, zero. Pixels on the PC do not move.


However, with patterns such as lighting and erasing pixels, we can feel "visually" as if pixels are moving on the PC screen. We are as good as reversing the fact that "the speed of pixel movement is zero".


Actually, the phenomenon occurring at the laser point on the moon is the same.


Laser particles are going to the moon at exactly the speed of light as per the laws of physics. Only the point of the laser point reflected on the moon is just moving at a speed exceeding the speed of light.


In the phenomenon that "the laser point on the lunar surface has moved beyond the speed of light", there is no such thing as "there actually moved beyond the light" and nothing has been overturned in the physical phenomenon. Only "image" that can be observed as visual information exceeds light. Unfortunately, we can not send messages at speeds beyond light and teleporting is impossible.


Among those who came up to this point, there should be some people who are clueless thinking that "Even though it is a laser pointer, when you arrive in the moon, it has spread to a circle of considerable size?" .


Depending on the laser pointer you use, when the laser pointer from the earth reaches the moon it will be a circle about 500 to 5000 kilometers in size.


"Because the accident that" the astronaut walking in the moon has become blind! "Can not happen because of the laser pointer you irradiated, please rest assured that the movie will be relieved."
