Reply to comment by autoantinatalist in If collagen is a protein, and proteins are broken down during digestion, why would collagen or collagen supplements be beneficial? Is it just hype? by skepticated
Collagen is made from vitamin C? Tell me more!

Reply to comment by Michaelmrose in How do fusion scientists expect to produce enough Tritium to sustain D-T fusion (see text)? by DanTheTerrible
Thank you for posting that. Doesn’t seem like it’s too promising right now, but it’s being worked on and moving in the right direction it seems. Hopefully they make some leaps forward in the next 5-7 years.

That's actually a fair point, and, I'll admit, I occasionally fall into the habit of believing in the light of a single genius still: That's pretty much never true. Thank you for the correction.

Newton wasn’t they only person working on Gravity. Robert Hooke (and others) developed a lot of the theoretical backing for Gravity. He just didn’t know Calculus so he couldn’t connect theory to observations. Imo, the popular picture of Newton is largely of his own design; he used his position of power to take credit for things like Calculus and Gravity and downplay those who help contribute.
Gravity like most discoveries wasn’t divined in a single moment by a single person but was dozens of astronomers, physicists, and mathematicians asking questions and pushing the boundaries of our understanding. Newton once said he was standing on the shoulders of giants because he couldn’t have made the discoveries he did without those before and around him.

If death didn't occur until after crossing the event horizon, then this would be the best way to die, imo
As you cross you'd be able to watch the universe age and die. You'd get a conclusion to the story... Right before you cells started to unmesh themselves from your body.
Trade offs, amirite ¯\(ツ)/¯

Not really pulled, more like, each element has its natural place, and it’s essence is to find its proper place. There was no force to do the pulling or floating, it was instead an essential property of a the element itself to organize in this way.

Got to admit I've never had a good concept of ageing with respect to speed. I can imagine a change in ageing when there is a speed differential, but once any two objects become adjacent again, say two atomic clocks, everything about relativity suggests they should show the same time again. If that weren't true then somehow relativity would be asymmetric, not conserved and/or there would necessarily be an absolute reference against which time dilation occurs, like what you are suggesting.

Reply to comment by Only_Philosopher7351 in has the speed of light always been constant? by 2bornnot2b
All this does is reframe the original question, not answer it. OP could ask if vacuum permeability and permittivity have always been constant. Simply saying that they are considered constant in EM theory is not a satisfying answer.
