How is space related to time?

Einstein, however, introduced the concept of a fourth dimension — time — that meant that space and time were inextricably linked. The general theory of relativity suggests that space-time expands and contracts depending on the momentum and mass of nearby matter.

Is time a function of space?

This formula shows by what factor time and space change for fast-moving objects, where length is divided by this factor, and its time is multiplied by this factor (slowing it down compared to the observer). So in short, time is a function of space.

How are space and time the same?

Thus, space and time are effectively interchangeable, and fundamentally the same thing (or at least two different sides of the same coin), an effect which becomes much more noticeable at relativistic speeds approaching the speed of light.

How do astronauts tell the time in space?

Q. How do they track time in space? A. Astronauts go by Mission Elapsed Time , or MET. In this time frame, the clock starts ticking when the astronauts blast off. Minutes accumulate into days, hours, minutes and seconds that have passed since liftoff. The clock stops when the Space Shuttle’s wheels again touch Earth, and the total MET is tabulated.

What is the longest time someone has been in space?

Polyakov’s record for longest cumulative time in space of 678 days over two missions stood until surpassed in 1999 by cosmonaut Sergei Avdeyev with a total of 747 days in space during three different missions.

Why does time move slower in space?

Answer Wiki. Now the reason that time runs slower in space is due to the earth being the heavy object that “weighs down” space time. It distorts it. And because space-time is responsible for how space AND time behaves, time is also distorted for the person in this bend zone.

What do astronauts do in their free time in space?

During free time, astronauts do things just like on Earth. They normally work out to stay healthy by sometimes using the treadmill while being stuck to the wall so they wouldn’t float since there is no gravity in space. they also practice their hobbies so once they go back to Earth they will be better at it.
