Stuff that falls into black holes gets crushed down to nothing then emitted as single socks on the other side and through spooky action find their entangled pair that have disappeared from washing machines over many years.
-
In my Montessori school I learned a bit of the theory of relativity and got super hooked on black hole information. Maybe it was a bit over my head but it totally got me interested in space for life. Never underestimate how smart kids can be and what kinds of stuff they'll latch on to.
-
Concerning a "Solar Slingshot", let's not forget that the HARDEST part would be the YEARS it would take to get even remotely close enough to the Sun in order to start the maneuver. Getting close to the Sun isn't easy.
-
Fraser - re the black hole mass of the solar system question. I thought the answer would be if all the mass was ADDED to the sun, would it be a black hole. That is of course no, as the sun is 99.86% of the solar system mass, so,adding the remaining 0.14% is negligible.
-
I'd add a question mark to the answer that everything falling into a black hole becomes more black hole. As a layperson I'm aware that information is supposed to be conserved rather than fully destroyed, even in a black hole and that in principle; infalling stuff should be recoverable and reconstitutable (in principle) at some point in the far future.

Scavenger’s Reign was so great. Can’t wait for a second season.
-
I love this channel. The most interesting channel I listen to I learn so much. Thanks for sharing Fraser.
-
YAY nature background again!!
-
Great Episode
-
When one is younger, one feels that you may know almost everything. That maybe the case for knowledge, but knowledge is knowing a tomato is a fruit, but wisdom is knowing not the put it in a fruit salad….. wisdom only comes with age and is always evolving until we pass on…

When I were a lad, it was still thought possible that there was vegetation on Mars. Now, it's a real world. And quasars were bright things at the edge of the universe. Now we have images of the central black hole. And knowing this stuff doesn't make it any less magical.
-
Very cool!
-
Matter that passes the event horizon adds to the mass of the black hole.
-
Pls bring back the forest background, reminds me of the old days. 6 or 8 years ago ❤❤
-
Love the new green screen background!
-
"Mirab, with sails unfurled."
-
Fun fact, a black hole with a diameter of 1 Planck length would have a mass a bit above 0.00001g It would go kaboom instantly tho.
-
Scavengers Reign was so good, highly recommend as well.

"Astronomers question if the first picture of a black hole is accurate" "Back-reaction of the Hawking radiation flux on a gravitationally collapsing star II"

I watched a documentary (I wish I knew what it was called) that covered what we "knew" about the universe before the launch of Hubble compared to after. And it blew me away. The things we learn seem, I don't know, natural? Normal? And it's hard to remember not knowing them.
