How does gravity affect time?

Gravity affects time through a phenomenon known as time dilation, which is a key concept in Einstein's theory of relativity.

Can you explain time dilation in simpler terms?

Sure! Time dilation means that time moves slower in stronger gravitational fields. So, if you're near a massive object, like a planet, time passes more slowly for you compared to someone far away from it.

Does this mean astronauts age slower in space?

Yes, that's correct! Astronauts on the International Space Station experience slightly less gravity, so they age a tiny bit slower than people on Earth.

Are there any real-life experiments that prove this?

Yes! One famous experiment involved atomic clocks on airplanes. The clocks on the planes showed less time had passed compared to those on the ground, confirming time dilation.
