When Is Now?

I love that physics just becomes philosophy when it gets deeper

Starting with a Spaceballs reference will always win me over.

Fun fact, the "view from nowhen" was believed by our ancestors to be the view that departed spirits had, which is why the ancients would ask the dead for advice and predictions about the future, since the greeks/romans believed them to be outside of time.

"that all moments are equally real and there's nothing special about the present moment except that you're experiencing it right now." I used to think of the world like that as a child, that everything is kept in it's own little place in history and once it happens it stays there, and isnt lost so the only thing that matters is that it existed once. Brings a lot of comfort

next time in an argument I say: "Well I guess you're right in your own reference frame."

"Time is what prevents everything from happening all at once." - Richard Feynman

For the first time in my life I was somewhat able to comprehend general relativity!!

Time is an illusion that helps things make sense~

When I saw the title, Spaceballs instantly came to mind... thanks for delivering on that thought!

I'm really grateful for videos like this because I used to talk about space time, and the illusions of reality in 7th grade, and I'd lose friends because I scared and confused them. I've found my people, and it feels nice.💙

Physicist Carlo Rovelli has a super interesting paper called “Neither Presentism nor Eternalism” that’s worth checking out if you’re interested in this stuff. He explains that while traditional presentism doesn’t make any sense with our modern understanding of physics, the “block universe” of eternalism isn’t the only philosophical alternative. It really comes down to what you truly mean by “present” and the ontological significance you apply to the idea of “reference frames.” Regardless of how you like to conceptualize time, I find his discussion to be very dope indeed 😎

“Now” doesn’t even feel like a word anymore

That spaceballs reference simply makes this video a 10/10.

The brain automatically synchronising discrepancies up to 100 metres is absolutely amazing! I had no idea it was doing that!

Then: Vsauce. Now: It's okay to be smart.

Pretty cool... kudos to all this team... the work in the script and visuals are stunning and awe inspiring.

Now is what is in between what is about to happen and what just happened. @ 6:40 I'm not sure if your model is right. You can not add speed to light but the light is moving with the train with means it moving faster than the speed of light to <- and slower than the speed of light to ->. The right model the center of propagation of the light should stay where the guy on the station is not move along with the train. This means that both observers would see the light reaching the back of the train first.
