Types of "Holes" in the Cosmos
Not all cosmic "holes" are the same — and they’re not just empty space.

What are the relationships between #Blackholes / #Whiteholes / #Wormholes
and #Cones / #Spheres / #Hypercones / #Hyperspheres?
…"In general #relativity, a white hole is a hypothetical region of #spacetime and #singularity that cannot be entered from the outside … #Whiteholes appear in the theory of 'eternal black holes'. In addition to a #blackhole region in the #future, such a solution of the #Einstein field equations has a white hole region in its #past"…

I'm beginning to suspect that #HawkingRadiation or #WhiteHoles are not responsible for the leaking of energy from #BlackHole s. The energy is actually somehow sent into small #kids during the night so they wake up bouncing.

Thanks to my 5 year old #BeardGrabber wanting to watch a video from #ActionLab, #TodayILearned a bit about the theoretical concept of #WhiteHoles.

You want Black Holes, we have Black Holes, you want White Holes, we have you covered, thanks to Brian Cox Jeff Forshaw & Carlo Rovelli
Warning, "spaghettification" risk!

Absolutely. Worthwhile reading up on #Penrose's work on this stuff too (#WhiteHoles and Penrose Diagrams). Deals with how these related spacetimes are (would be) connected.

Un buco nero quantistico che deforma lo spazio-tempo. Non il solito buco nero: ecco il solitone topologico, con una "bolla" al posto della singolarità. L’oggetto emerso dalle simulazioni di tre ricercatori della Johns Hopkins è un’ipotetica costruzione matematica basata sulla teoria delle stringhe.

White holes: Facts about black holes' neglected twins
White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes. More recently, however, some theorists have been asking whether these twin vortices of spacetime may be two sides of the same coin.

Is it time to update the constellations? On this episode, Neil deGrasse Tyson and comic co-host Matt Kirshen dive into astrophysics, folklore, and our ancient connection to the stars with astrophysicist Moiya McTier, Ph.D.

A shout out to all my fellow nerds who learnt about the existence of #WhiteHoles, not from high-brow science programmes, but from #RedDwarf! :blobcatspace: #SciFi #ScienceFiction
