Universe in a bubble

Quote:
Maybe we don’t have to speculate about what life is like inside a bubble. It might be the only cosmic reality we know

Colliding Dead Stars May Explain the Milky Way's Mysterious Antimatter

https://www.seeker.com/space/astrophysi ... antimatter

Quote:
The majority of antimatter that pervades the Milky Way may come from clashing remnants of dead stars, a new study finds.

Wormholes Untangle a Black Hole Paradox

https://www.quantamagazine.org/wormhole ... -20150424/

Quote:
A bold new idea aims to link two famously discordant descriptions of nature. In doing so, it may also reveal how space-time owes its existence to the spooky connections of quantum information.

The Universe Should Have Destroyed Itself at the Big Bang. Why Didn't It?

https://www.seeker.com/space/astrophysi ... y-didnt-it

Quote:
The mystery of why the universe exists has deepened as an ultra-precise comparison of the magnetism of matter and antimatter shows no difference.

How Black Holes Shoot Out Lethal Plasma Jets Is Becoming Clearer

Quote:
Researchers are trying to understand the extreme physics of black holes, and are zeroing in on how they project bright columns of hot gas and radiation.

Physicists Hunt for the Big Bang’s Triangles

Quote:
The story of the universe’s birth — and evidence for string theory — could be found in triangles and myriad other shapes in the sky.

The Fuzzball Fix for a Black Hole Paradox

https://www.quantamagazine.org/how-fuzz ... -20150623/

Quote:
By replacing black holes with fuzzballs — dense, star-like objects from string theory — researchers think they can avoid some knotty paradoxes at the edge of physics.

Make the Cosmic Perspective Your Next Coping Mechanism

http://nautil.us/blog/make-the-cosmic-p ... -mechanism

Wow.

Of relevance from Douglas Adams's The Restaurant At The End Of The Universe:

Quote:
The Total Perspective Vortex derives its picture of the whole Universe on the principle of extrapolated matter analyses.
To explain—since every piece of matter in the Universe is in some way affected by every other piece of matter in the Universe, it is in theory possible to extrapolate the whole of creation—every sun, every planet, their orbits, their composition and their economic and social history from, say, one small piece of fairy cake.
The man who invented the Total Perspective Vortex did so basically in order to annoy his wife.
Trin Tragula—for that was his name—was a dreamer, a thinker, a speculative philosopher or, as his wife would have it, an idiot.
And she would nag him incessantly about the utterly inordinate amount of time he spent staring out into space, or mulling over the mechanics of safety pins, or doing spectrographic analyses of pieces of fairy cake.
"Have some sense of proportion!" she would say, sometimes as often as thirty-eight times in a single day.
And so he built the Total Perspective Vortex—just to show her.
And into one end he plugged the whole of reality as extrapolated from a piece of fairy cake, and into the other end he plugged his wife: so that when he turned it on she saw in one instant the whole infinity of creation and herself in relation to it.
To Trin Tragula's horror, the shock completely annihilated her brain; but to his satisfaction he realized that he had proved conclusively that if life is going to exist in a Universe of this size, then the one thing it cannot afford to have is a sense of proportion.

Astronomers Found a New Type of Cosmic Explosion

http://www.popularmechanics.com/space/d ... explosion/

Quote:
It could be a supernova, or a black hole shredding a star, but it sure is massive.

Astronomers Reveal Nearby Stars That Are Among The Oldest In Our Galaxy

http://www.astrowatch.net/2017/11/astro ... -that.html

Quote:
The team’s work increased the known population of old stars in our solar neighborhood by 25 percent. Among the new subdwarfs, the researchers discovered two old binary stars, even though older stars are typically found to be alone, rather than in pairs.
