“Is time relative or absolute”? There are two main factors time is dependent on, Gravity and speed.
Newton says that time is absolute and every event is synchronized with one clock.
While Einstein says that time is relative. It is different in space and on earth.
Einstein says that if a person is in such a frame of reference where gravity is highly effected so he won’t observe the slow down effect of time because everything is slowing down even signals from the brain slow down.
But a person looking form outside of this frame of reference will clearly observe the slow down effect.
The second reason which Einstein explains for the slow down effect of time is speed. If a person is traveling with the speed of light, time stops. But he won’t observe the effect until he is looking from a stationary point of reference.
Do Astronauts Age Slower than on Earth? Here is a famous problem of time relativity which is called the Twin paradox. Suppose we have two twins. One is set to free in a rocket with a 90% speed of light. For him, the clock speed remains 44%. If we increase the speed to 99% the speed of light, the clock speed remains 14%. And If we increase the speed to 99.99% the speed of light, the clock speed remains 4%. In this case, if the child returns after 100 years. He will be just 5. However, if he is traveling with the speed of light, time stops for him.
Clocks near a black hole would tick more slowly than those further away from the black hole. Due to this effect, known as gravitational time dilation, an object falling into a black hole appears to slow as it approaches the event horizon, taking an infinite time to reach it.
Do you know that Colonization of Mars will take place in 2020 by Elon Musk.
Does Time Exist in Space? If gravity is high time slows down. Black holes have the highest gravity; therefore, time stops in black holes. In 1971 two scientists made an experiment to prove that time is relative. They had two atomic clocks. They set one clock on a plane. After the observation, they found that one clock was 100 billion part of a second.
