ELi5 If time is slower at space, would you still age at the same rate as you would on earth?
In: Physics
If time passes slower for you (can be caused by being in a high gravity field or moving at incredible velocities) you will perceive time as moving the exact same, even if it is not. This is because your brain would also function slower as well. If time appears to have passed 10 years, you will age 10 years, but someone on Earth where time moves differently, they would age a different amount in that same amount of time.
For example, if John is in a rocket where time only moves at 20% that of time on Earth, John will age only 1/5 the amount of time. If 50 years passes on Earth, John would only perceive that as being 10 years that have passed and will only have aged 10 years as well.
