The Mind-Blowing Science of Time and Light

⏳Time slows down as you move faster. The fabric of space-time slows down time under certain conditions.

⚖️Gravitational fields also slow down time. The stronger the field, the slower time ticks.

🛰️GPS satellites need to pre-correct their time signals to compensate for the effects of relativity.

💡Particles that travel at high speeds, like in particle accelerators, also experience time dilation.

☄️Photons, the particles of light, have no internal clocks and do not experience time. They travel through space without aging.

How does time dilation work?

—Time dilation occurs when the fabric of space and time slows down under certain conditions, such as high speeds or strong gravitational fields.

Why do GPS satellites need to pre-correct their time signals?

—GPS satellites orbit in a gravitational field that is different from the Earth's surface. To ensure accurate timing, the satellites need to compensate for the effects of relativity.

Do all particles experience time dilation?

—Particles that travel at high speeds, such as in particle accelerators, can experience time dilation. This is due to their motion through space-time.

Do photons experience time?

—No, photons do not experience time. They have no internal clocks and do not age as they travel through space.

Can time travel be achieved through time dilation?

—Time dilation allows for differences in time to exist depending on the speed or gravitational field. While it's not exactly time travel in the science-fiction sense, it does create interesting effects.
