White Holes Explained - Patreon Bonus Video
Added 2024-05-14 12:43:39 +0000 UTCDid our universe emerge from a white hole? How confident should we be that parallel universes exist? In this exclusive bonus video, the brilliant Prof. Geraint Lewis expands on some of the awe-inducing topics covered by our recent video on general relativity.

Youtube disallows adblocers. They've nnow disabled the player on browsers that use adblockers. Since I can no longer watch your videos on youtube, there's no point in supporting you on patreon. I hope you and the other patreon creators I support will make youtube understand this is a really, really bad move on their part. If they don't reverse that policy, I'll be cancelling all of my patreon subscriptions. Sad to do this. I hope you can make them change.

2024-05-20 15:47:47 +0000 UTCA special case of the "second universe" theory would be: If you wrap the "two squares and two triangles" picture on a toilet roll such that the squares overlap perfectly, then it would be just one universe..

2024-05-15 16:09:11 +0000 UTCThanks for the inside clip. It would be nice to get a definition of an "Universe". The conversation/explanation would be much easier to follow if the concept of "Universe" is defined before discussing the ideas of black holes and white holes connecting universes. To me Universe seems to be the space-time everything exists in. To imagine the possibility of multiple universeres there needs to exists another Superverse within which we can imagine Universes. Others may imagine a "Universe" completely differently. So, it will be good to get a baseline definition.

2024-05-14 18:55:13 +0000 UTCI think his point is that until one has a way to invalidate particular solves with a physical test -- such as your freezer example -- then it is valid until proven otherwise and cannot be flippantly thrown out.

2024-05-14 18:16:59 +0000 UTCMath isn't real ;-) I can calculate that -300°C is 300° colder than 0°C. But you can't get a freezer to -300°C. Physics does not give in to math.
