Here's a thread of reviews of #EndOfEverythingBook -- because they've honestly all been really fantastic and it makes me SO HAPPY to see how much people are enjoying my book now that it's officially out there in the world! ✨📚✨
"'The End of Everything' is a pleasure. Mack’s style is personal and often funny ... I found it helpful — not reassuring, certainly, but mind-expanding — to be reminded of our place in a vast cosmos." -@nytimesbooks
"...like an animated discussion with your favourite quirky and brilliant professor. ... If you need a moment to be distracted from everyday life and journey to the deep cosmic future, I highly recommend 'The End of Everything.'" -@newscientist
“Mack takes an otherworldly subject—the death of the universe—and brings it down to earth....'The End of Everything' will delight both casual science readers and those looking for more in-depth analysis of theoretical astrophysics.” -@bookpagebookpage.com/reviews/25397-…
"Mack’s account mixes a sense of reverence for the wonders of physics with an irreverent sense of humor and a disarming dose of candor.... Reading Mack’s prose feels like learning physics from a brilliant, quirky friend." -@ScienceNews
“Mack’s endlessly entertaining survey is infused with a palpable love of her subject, and will transmit to readers the same joy she finds in exploring the wide and fascinating universe.” -@PublishersWkly (starred review)
"Mack uses humor, metaphor, and personal experience to offset her often technical descriptions, creating a delightfully unsettling narrative that explains big ideas in modern physics and cosmology through the lens of end times." -@KirkusReviews
“In Mack’s hands, this speculation makes for a fascinating story. … She is a talented communicator of complex physics, and the passion and curiosity about astronomy that have made her a popular speaker and Twitter presence are evident here.” -@nature
"All in all, 'The End of Everything' serves as an outstanding, levelheaded guide to a horrific medley of ways the Universe might expire. The book is the perfect antidote to the malaise of mundane worries." -@ScienceMagazine
“Beyond her deep expertise, Ms. Mack’s infectious enthusiasm for communicating the finer points of cosmological doom elevates 'The End of Everything' over any other book on the topic I have read.” -@WSJ
The news is out! The @NANOGrav pulsar timing array collaboration has detected a background of cosmic gravitational waves rippling through our Universe! Let’s talk about it!
(Full press conference tomorrow, ) 1/n https://t.co/5jd4mp989Wnanograv.org/news/2023Annou…
@NANOGrav Q: What does this mean?
A: Whenever violent gravitational events (like colliding black holes) happen in the cosmos, it causes ripples in space itself: gravitational waves. This is the 1st detection of a “stochastic background” of these waves, coming from all over the cosmos.

@NANOGrav Q: What are pulsars?
A: Pulsars are ultra-dense neutron stars (remnants of dead stars) that have jets of radiation coming from their poles & rotate rapidly. Typically the jet isn’t aligned with the pole, so it sweeps around. When it hits us, we get a pulse.

Nothing exemplifies a complete failure to understand the point of science like demanding to settle a scientific issue through the medium of emotionally persuasive public shouting
We actually do a lot of arguing and debating within science! But — and this is pretty important context — we do it with knowledge and expertise already in hand, having read and understood the relevant literature, and for the purpose of improving the work. Not to win via applause.
Scientists don't do everything right & our methods aren't always unimpeachable.
But there's really not enough awareness that most of us spend a HUGE amount of our time trying desperately to find flaws in our own & each others' work. And we are very well equipped for this!
We don’t call Trump a liar and criminal because we don’t like him. We don’t like him because he’s a liar who does lots of crimes.
He has explicitly bragged that his fans would happily excuse his crimes even if they were murders in the streets; let’s not pretend the righteous indignation and claims of innocence are genuine.
I don’t think the right wing seriously believes he’s not a criminal. I think they just understand that it’s more socially/politically acceptable to play-act outraged credulity than to admit they don’t care about rules or honesty as long as their guy is winning.
I applied to Twitter for verification in 2016, when I had about 40k followers and was starting to have a voice in the online astronomy/physics community. The checkmark suddenly appeared shortly after a snarky tweet of mine went super viral and my following doubled in a week.
I don’t know how much of it has been due to going viral, or to my science, or just to how I tweet in general, and I don’t know how much verification helped, but I built up a wonderful little network of amazing people here whose work I admire and whose friendship I truly value.
Twitter has had its bad aspects for sure but for me, it’s been a doorway into a room full of my heroes, & a chance to listen to voices I might otherwise never encounter. I don’t know what it will be when so many people whose company I treasure find it no longer worth their time.
The point of Twitter verification is that for certain individuals/organizations it’s useful to be able to verify their statements are coming from them. (This is why so many journalists/reporters are verified.) It’s supposed to help combat disinformation, not be a status symbol.
People think of it as a status thing because a lot of people with status are verified but the causality is that if you’re well known, you’re more likely to be a target for impersonation and/or there’s more public interest in being able to verify that your statements are yours.
(This is not to say that Twitter verification is always applied sensibly/fairly. It certainly isn’t. And the verification distribution system has been bad in many ways for a long time. But turning it into purely a vanity accessory for pay would in fact be worse.)
This is an image of the Cosmic Microwave Background (CMB). It's a projection of the whole sky onto an oval, aligned such that the center of the image is in the direction of the center of our Galaxy, and the edges are the opposite direction.
The CMB is often described as the afterglow of the Big Bang, but it's actually a DIRECT view of the Universe around us -- of parts so far away that the light has been travelling for about 13.8 billion years, so we see those regions as they were when the cosmos was STILL ON FIRE
In the early universe, all space was filled with hot dense plasma: space was aglow. Then, as time passed & the cosmos expanded, that plasma cooled & the gas became dark. So we see the bright plasma THROUGH the dark gas; the Cosmic Dark Ages are *closer* to us, backlit by the CMB
