Study claims to provide first direct evidence of dark matter
The signal "closely matches the properties of gamma-ray radiation predicted to be emitted by dark matter," Totani told the Guardian. Details are published in the Journal of Cosmology and Astroparticle Physics.

The End Of Everything (The 1A)
With everything that’s going on right now, it can sometimes feel like the world is ending. There are massive wildfires that cause fire tornadoes, permafrost melts that explode, and…the coronavirus pandemic. But cosmologist Katie Mack says we should all stay calm, at least for the next several billion years.
In her new book, “The End of Everything (Astrophysically Speaking),” Mack writes about how the universe works and how it could eventually come to an end.
Here’s one theory she puts forward, as summarized by The New York Times.

In her new book, “The End of Everything (Astrophysically Speaking),” Mack writes about how the universe works and how it could eventually come to an end.
Here’s one theory she puts forward, as summarized by The New York Times.
Other possibilities involve dark energy, a still poorly understood business that seems to be the dominant component of our universe. A dark-energy apocalypse could “tear apart the very fabric of reality, rendering any thinking creatures in the cosmos helpless as they watch their universe being ripped open around them,” Mack says. Some paths to destruction arise from theories that involve parallel universes lurking in extra dimensions. A so-called “ekpyrotic” scenario imagines collisions of “branes,” three-dimensional universes ordinarily invisible to one another. At the fringes, the cosmological theories with the best jargon and cleverest names are often the most speculative.Whether it all ends in a bang or a whimper, Mack offers us a glimpse into what it all means — and how it all could conclude.

Inside the black hole image that made history | Sheperd Doeleman
At the center of a galaxy more than 55 million light-years away, there's a supermassive black hole with the mass of several billion suns. And now, for the first time ever, we can see it. Astrophysicist Sheperd Doeleman, head of the Event Horizon Telescope collaboration, speaks with TED's Chris Anderson about the iconic, first-ever image of a black hole -- and the epic, worldwide effort involved in capturing it....
