Is time relative? On this explainer, Neil deGrasse Tyson and comic co-host Chuck Nice explore facts about Einstein’s theory of relativity that keep them up at night. Does time always move at the same rate? Discover fascinating properties of the fabric of space and time. Is it true that the faster you move, the slower time ticks for you? What other variables affect the passage of time? Find out about the passage of time on objects orbiting Earth and how we compensate for that here on the surface. Does time dilation affect satellites? What is time like for an object traveling at the speed of light?

"If you can't explain it simply, you don't understand it well enough." Neil does it effortlessly. Amazing video.

To me, the craziest thing about this is how Einstein conceptualized these theories in his time. I wonder how much different things would be today if he had never lived and we had to wait 50 years for someone to come up with these in say the 1950's or 1960's. Einstein is the GOAT in science without a doubt.

This is what I got from this: “go fast, time slow”

So the analogy I’ve came up with to describe this is like when in a car on the highway looking out the window you can see things clearly and it’s like your going slow; yet when your watching a car drive by on the highway they zoom by super fast.
