Parth G | Einstein Didn't Invent Relativity! - Physics Explained for Beginners @ParthGChannel | Uploaded 4 years ago | Updated 3 hours ago
Find out who came up with the concept of relativity in this video.
Hey guys, I'm back with the final video on this channel for 2019! I hope it's been a good year for you.
In this video, I wanted to discuss relativity, in order to get away a bit from the usual quantum chat. A lot of you wanted me to make a video about relativity, so I thought I'd make one, but not focus on Albert Einstein's theories of Special and General Relativity. Did you know that Galileo was the first person (as far as we know) to come up with a way of dealing with relative motion?
He based his ideas on what we now call Newtonian (or Classical) Mechanics, which is full of "common sense" ideas about how the universe works. One such idea is that of "universal time", which says that everybody in the universe experience time in the exact same way. One second passing for me is the same as one second passing for you, even if we are moving at different speeds relative to each other. Now this seems to make sense to us, but this is not how the universe works.
When Einstein came up with Special Relativity, he decided to incorporate the idea of a constant speed of light, which dropped out of the mathematics of Maxwell's equations. Scientists at the time thought that this was a mistake, but Einstein decided to run with it and see where it took him. It turned out that his ideas were a better representation of how the universe behaves. We now have a lot of experimental evidence suggesting that the universe works the way Einstein thought it did, and not how Galileo thought it did.
Here's a nice video by minutephysics explaining Time Dilation and Length Contraction, which is what Einstein had to allow to be a thing in order for the speed of light to be constant in his ideas. https://www.youtube.com/watch?v=-NN_m2yKAAk
