This was a very fun present to unwrap. When you called me and told me to turn the camera on I knew something weird was going to happen and you certainly delivered. As long as I’ve known you Derek you’ve been destroying assumptions. Thank you for this friendship. It’s certainly enjoyable from my perspective.

Great video. Despite getting a physics degree and teaching physics for years, I never came across this or thought about it. I was treating the video mostly as a 'fun to think about' sort of video, but your point at the end is really intriguing.
@mattmcbee
Fascinating video. A couple of thoughts: 1) c is defined by the permissivity and permeability of free space. If it has directional anisotropy then the way these physical constants are defined is wrong. 2) if c varies directionally, I I wonder if this would be detectable by astronomers. For example, perhaps we'd see different stages of galaxy evolution in different directions, or perhaps we would observe differences in the cosmic microwave background in different directions.

Should have wrote this in my physics exams, "It is neither a supposition, nor a hypothesis, but a stipulation that I can make of my own free will"

I love when Destin is presented with something he genuinely didn't know/understand before. His face lights up with extreme excitement and intrigue.

My real takeaway is that two clocks, regardless of precision, will never be truly synchronized. This explains why I am frequently late.

"So someone has measured the speed of light...or have they?" Huge Vsauce moment right there
@godzillaxred
4:06 - "Or have they?" I feel like this was a missed chance to put the vsauce theme on
@sandervanliempd851
I love how you worded the last part. Because that is exactly the words I would use to describe what I found. Though it doesn't have anything to do with measuring the speed of light. I do wonder why we never saw it before.
@ristopaasivirta9770
I like the extra effort you put into the short acting parts to visualize the concepts.

"so someone has measured the speed of light... or have they?" Hey, Vsauce... Michael here

I love how he called it right off the bat, “oh you’re talking relativity, you’re gonna something weird aren’t you?”
@fr3nchy226
This is the best explanation of "WHEN WILL THEN BE NOW?" I've ever seen.
@Birginio420
He said "or have they?" I was kinda sad no vsauce music played
@hobsdigree2
By this logic, do we really know the speed of anything? Did I just find a way to talk myself out of a speeding ticket?
