Why didn’t the world fall into space?
The Earth revolves around the Sun in the great expanse of space. The orbit around the sun is around the sun’s equator. So, the question is whether or not it will go down if it goes around in this line. This is a question that many people ask when they see the Sun from Earth and the planets orbiting…
Can you time-travel and change the past?
In 1905, Einstein proposed the relativity theory. Since this time, among scientists (especially physicists later), time travel has been seriously discussed and researched. Some believe it is possible to time travel into the past. Most physicists believe that time travel to the past is “theoretically possible”. So here comes a question. If we could time travel to the past,…
Infrared What is infrared radiation?
Infrared, translated as infrared radiation, is actually an electromagnetic wave. This infrared radiation cannot be seen by the human eye. But its radiation waves can be felt as heat. Simply put, it’s a heat wave. It’s not exactly true. But for those who don’t have a physics background, it’s easy to understand because infrared radiation is compared to heat…
What is gravity?
“Gravity” is a kind of force. This gravity is the massive stars force, The force that pulls other objects from the planets to their centers. In theory, all objects with mass have gravity, but the gravitational force they exert is so weak that it can only be seen significantly in massive objects such as planets and black holes. This…
If the world stopped
The Earth spins on its axis once every 24 hours. This has been going on for millions of years. It will not be possible for the next millions of years to stop going around like this. To stop suddenly is even more impossible. But if the world stopped spinning, let’s think about what would happen as a consequence. There…
