5 physics revolutionary fantasy experiments by Einstein

Experiments riding on a beam of light, or paradoxes of twins are two of the five imaginary experiments that led to Albert Einstein's revolutionary physics proposals, one of the greatest minds of the century. 20.

According to Business Insider, this is the experiment Einstein thought of in 1895, when he was 16 years old. What if you chase and catch a beam of light?

According to Einstein, you will see light freezing in space. But light could not be frozen, so Einstein realized that light would never slow down and always move away at the speed of light. Therefore, another thing must definitely change. Finally, he realized that it was time. This conclusion laid the foundation for his special theory of relativity proposed in 1905.

Experiments on trains were struck by lightning

Imagine you're sitting on a moving train and a friend stands outside the train watching as it passes. If lightning strikes both ends of the train, the person standing outside will see two events occurring at the same time.

And the people on the ship are getting closer to the lightning in front of the train, so they will see lightning at the top first. This experiment has shown that time for people is different from the restless person, reinforcing Einstein's belief that time and space are relative, concurrency cannot exist. This is also a foundation in Einstein's special theory of relativity.

Paradoxical twin experiments

This is a famous variation from Einstein's light meter experiment.

Suppose you have a twin brother, born exactly at the same time as you. That person after birth was immediately brought up on a spaceship moving at nearly the speed of light.

According to relativism, two people will then have different ages. As time passes more slowly when the speed is higher, people on the spacecraft will age more slowly than people on Earth. When the ship returns to Earth, you may have retired, and the other one will be puberty.

Experiment on the box

Imagine you are floating in a box, not looking outside. Suddenly, you fall to the floor. What happen? Is the box pulled down by gravity or is it accelerated pulled up by the cable?

The two effects lead to a result that led Einstein to conclude that gravity and acceleration are the same. Along with previous assertions that time and space are not absolute, Einstein argues that if motion can affect space and time, gravity must have a similar effect.

The ability to space-time bending of gravity is a huge part of general relativity.

Experiment with coin toss

Einstein always opposed quantum theory and always thought of experiments to refute this theory. However, these are just experiments that challenge pioneering scientists in this theory to perfect it to the smallest detail.

One of those experiments was the experiment of quantum entanglement, which Einstein called "spooky effects from afar".

Imagine having a two-sided coin that can be easily split apart. You roll it up, don't look, give half to the other and keep the other half. The other will carry half that coin around the universe.

Then, just by looking at the face of your half-coin, you will know immediately the face of the other person's coin, regardless of whether they may be billions of light years away from you and without a physical connection. together.

If the sides of the coin are considered to be indeterminate, it is possible to change the state of the dial or face until the time is seen, meaning that the change of the coin faces is much faster than the speed of light Immediately affect each other (this side of the number must be the picture and vice versa), regardless of how far apart.

This is in contrast to Einstein's Theory of Relativity, which considers the speed of light to be the greatest. However, today this quantum entanglement paradox has been proved to be true and applicable in modern technologies such as quantum computing, quantum cryptography, quantum teleportation.
