Can you imagine life if the speed of light was a mere 3 km/s instead of 300,000.
Could #Tachyons Exist? Breaking the #SpeedOfLight
❛❛ a popular notion floated around by proponents of Tachyons is that Tachyons could be used to transmit #signals back in time, which opens up the door to some interesting #paradoxes. ❜❜

Colorful critters teach some basics of time travel #theory in this 11-min #animation (with ads). One concept not widely illustrated elsewhere is that everything is moving at the #SpeedOfLight within the 4 dimensions of #SpaceTime. As we move faster through #space, our time slows down proportionally (relatively?) If we #stop, our time speeds up to maintain the constant #velocity.
@jerry Having recently been read Max Tegmark's 2014 "Our Mathematical Universe", I strongly recommend it - not just for Max's fascinating perspective on the larger question, but for getting the reader (listener) to the point to be able to understand it. Your library system probably has a few copies.
Fifteen hours at 3× is "only" five hours.
From the frame of reference of massless particles such as the photon, there is no time. They experience every moment from the beginning to the end of their universe simultaneously. Consequently they can listen to audiobooks at any playback speed.
Concerning 137, see https://www.youtube.com/watch?v=RCSSgxV9qNw (and all the other videos on this channel).

#Harvard October 11, 2022 : Some spaghettified material occasionally gets flung out back into #space
. #Astronomers liken it to #BlackHoles
being messy eaters — not everything they try to consume makes it into their mouths.
But the emission, known as an outflow, normally develops quickly after a #TDE occurs — not years later.
The outflow of material is traveling as fast as 50 percent the #SpeedOfLight. For comparison, most TDEs have an outflow that travels at 10 percent the speed of light https://news.harvard.edu/gazette/story/2022/10/black-hole-burps-up-shredded-star-years-after-consuming-it/

We've had relativity, the physics of time, genius, the speed of light, the Grand Unified Theory, photons, black holes, quantum physics - but this is the first time Melvyn Bragg and his experts have considered Albert Einstein himself.
About time, you might say.
