Why Time Is Mystery In Physics | COSMOS in a minute #16

Time is weird. It slows down at high speeds and around massive objects. It completely stops at the speed of light and at the event horizon of a black hole. And finally, it doesn't even exist at the singularity, the center of a black hole. When Newton developed his laws of classical mechanics about 400 years ago, he assumed that time and space are absolute. This means that no matter where you are in the universe, time would be the same. One second on Earth must be equal to one second on any other planet. However, Einstein turned that around. His theory of relativity says that only the speed of light is constant, and space and time, intertwined in a cosmic fabric, are relative. What appears to be a second near a black hole could be thousands of years on Earth. So remember, time is not just a tick-tock on the clock, it’s a cosmic dance, a reminder that the universe never ceases to amaze.

The concept of time has always fascinated me. An incomprehensible, invisible dimension that acts like a universal clock, and can only be changed around a literal rip in reality.

Before this video i used to understand what time is, but now I don't

When newton blinked, I had the scare of my life.

"Time is an Illusion"

Sometimes it just feels like an illusion.

*"Time is discovered by clock mechanics to sell more clocks"*

This concept is actually literally mind-blowing to most people who cannot conceptualize it. And it is hard to do for sure.

One minute you're eating breakfast, the next minute you're already planning what to have for dinner. It's like time has a crush on the fast-forward button or something

The fact that interstellar illustrates this so well with gargantua and millers planet

"The Night of Mairaj" is greatest example to know and explain the Time on our Earth and the Time at Skies

[linmonash]

Can I use that next time I'm late for a meeting?
" Sorry folks, it's just that time is a cosmic dance... and I'm just 5 minutes less cosmic than the rest of you!"

Thank you, for reminding me that time is not just a tick tock

Hydrogen is hydrogen across the universe. But time is relative to where you are at.

[kimmagtulis]

"Time is a cosmic dance" is such a beautiful line tho 💖

[DarknessGamingAtYoutube]

Had to reply the video i thought i was seeing things haha that picture eyes were moving 😂

[helicopterpantherstudiosyt]

ah yes time is weird, it seems to slow down when your in school

[biblest]

It reminds us of how little we actually know about all.

[blackeaglenrzero]

So if you'd fall towards a black hole you'd feel agony literally forever? That's hell

Coordinate time asymptotes at the event horizon, this is the time you would see if you zoomed in on a clock crossing the event horizon. The proper time, which is the time the person holding the clock feels, continues as normal.
