Thanks to Einstein’s theory of special relativity, we can all agree that the speed of light is constant for all observers. We can also agree that, if you’re not a photon, approaching light speed comes with some pretty funky rules – namely, anyone watching you will see your length compress and your watch slow down.
But the slowing of time also occurs near gravitationally potent objects, which are described by general relativity. So if you happen to be sight-seeing in the center of the Milky Way and you make the regrettable decision to get too close to our supermassive black hole’s event horizon (more sinisterly known as its point-of-no-return), anyone observing you will also see your watch slow down. In fact, he or she will witness your motion toward the event horizon slow dramatically over an infinite amount of time; that is, from your now-traumatized friend’s perspective, you never actually cross the event horizon. You, however, will feel no difference in the progression of time as you fall past this invisible barrier, soon to be spaghettified by the black hole’s immense gravity.
So, who is “correct”? Relativity dictates that each observer’s point of view is equally valid; but in this situation, you can’t both be right. Do you face your demise in the heart of a black hole, or don’t you?

Spaghettification! Now you’re making’ me hungry! If I can just stretch out my snack,,,,,,,,,
Annnnnnd... It’s gone.
Ah yes, the old "Fly suspended in amber"......
“a daring claim: at certain scales, space and time simply do not exist”
Seems like a not-so-daring extrapolation from the Big Bang theory. Or even from the assumption that the universe derives from *something* not defined by time or space.
Something that is omnipresent, and without beginning or end?
“Something that is omnipresent, and without beginning or end?”
You’re onto something, but, judging by his books, Hawkings would likely demur.
Really, all we ever have is Here and Now.
Did they just forget to put an “A” in front of Holes in the title?
Black holes are outta sight!
Unfortunately, none of this will help dieters. Thanks BenLurkin.
Any of you a physicist published in a peer reviewed journal or know one? If so, please mail me. Had a project come across my desk and need one.
I don’t see how they got to the title from the text of the article.
Stephen Horndog sure changes his mind a lot. Like his women.
Jumpin' Jiminy Cricket! If they'd just pay attention to me and give me my Nobel Prize right now for LibWhacker's Law, they wouldn't be so confused. LibWhacker's Law says that if you are a pathetic weak and squishy little critter whose very life depends upon a dozen or more parameters being in some precise tight little range, then there is no way in Hell you're going to survive inside a black hole where those parameters are going to be all over the board (or even nonexistent)... Temps in the trillions of degrees, pressures that would crush a thousand-mile-wide ball of solid iron to a subatomically thin goo, no oxygen, no water, no booze, no ice, no steak, no burgers, everything flying around at the speed of light, etc., and then BOOM, suddenly time disappears, space disappears and... Why ARE you asking me such a dumb question such as "Could I survive it, Perfesser? Please tell me I could live through it." No, you could not. Not even. End LibWhacker's Law.
