In the world of physics, the concepts of speed and motion are often discussed. Especially the speed of light, Einstein’s It is considered a limit together with the theory of relativity. Well, a person traveling at the speed of light on the train What happens if we are passengers and walk towards this train?

Come on, everyone together of light the depths Let’s find the answer to this question by investigating it.

Let’s first look at the speed of light.

The speed of light is a very important concept in physics and is approximately 1000 seconds per second in a vacuum environment. 299,792 measured in kilometers. According to Albert Einstein’s theory of relativity, the speed of light is the highest speed that can be achieved in the universe. highest is the speed limit. This limit applies not only to light, but also to all kinds of physical objects and information.

Let’s look at our topic according to the special theory of relativity.

This theory states that classic speed rules do not apply at high speeds. According to special relativity, the combination of any two speeds gives the speed of light. can’t get over it. So if two objects are moving at high speed relative to each other, the sum of these two speeds can be calculated by simple arithmetic addition. not calculated.

Instead of; The sum of the speeds ensures that the result never exceeds the speed of light. special A per method is determined.

Okay, let’s come to our train example.

Let’s imagine a train, at the speed of light It moves at a very similar speed. You are on this train and the direction in which the train is moving to walk Imagine yourself starting. You may think that you will instinctively add your walking speed to the speed of the train and get faster, but that’s not how things really work.

At low speeds under normal conditions two speeds Once you’ve collected everything, you can easily add the results. For example, imagine that you are riding a bicycle at a speed of 10 km/h on a road and that you are moving forward on the bicycle at a speed of 5 km/h. In this case your total speed is 15 km/h. However light at the speed This is not the case at short speeds.

As you approach the speed of light, adding speed requires another mathematical operation. But without diving into the formulas Ordinary To express; It doesn’t matter how much you add to your speed, your total speed your speed of lightYou can’t get over it.

Bonus: What’s the Fastest Man-Made Object?

The fastest man-made object launched by NASA Parker solar probe‘Stop. As this spacecraft approaches the sun, it travels approx 394,736 miles It reached the highest speed and became the fastest man-made object. This extraordinary speed was made possible by gravitational maneuvers around Venus.

Parker Solar Probe’s mission is to of the sun to study the outer corona and better understand the solar wind and energetic solar particles.
