Every week, we do a little round-up of comments from the Big Think Facebook. Here’s some of the more intriguing ones of the week.

As wonderful as the evidence that supports or invalidates a theory is, it can never truly kill the ones that don’t work out. When it comes to science, we like to […]
The iconic physicist warns that we’d better find another planet in the next 100 years, or humanity is screwed.
If it weren’t just the three space and one time dimensions, what would be different? “There is a fifth dimension, beyond that which is known to man. It is a […]
If you haven’t finished your holiday shopping yet, consider these 10 gifts, good any time of year! One of the hardest things when it comes to holiday shopping is to find […]
The ELT, at 39 meters in diameter, will dwarf everything that’s ever come before. “There are so many people who are arguing or fighting over issues which don’t have much relevance. […]
If it’s the anti-version of normal matter, could it possibly fall “up”? This article was written by Sabine Hossenfelder of Backreaction. Sabine is a theoretical physicist specialized in quantum gravity and […]
The first stars formed almost half a billion years before we could see their light. Here’s why. At the moment of the Big Bang, the Universe was full of matter and […]
Why weightlessness is possible, even if there’s no place you can hide from the Universe’s longest-range force. “It was a strange lightness, a drifting feeling. Zero gravity. I understood that […]
A live-blog event happened a week ago, but you can catch the entire thing anew here, right now! “We have never observed infinity in nature. Whenever you have infinities in […]
The atoms, planets, stars, and even galaxies aren’t expanding, even though space is. How come? This article was written by Sabine Hossenfelder. Sabine is a theoretical physicist specialized in quantum gravity […]
With a journey of 130 million light years, both signals should move at the speed of light. So why did one get here first? On August 17, after a journey taking […]
From a Universe that went no bigger than our Milky Way to the trillions of galaxies in our expanding Universe, our knowledge increased one step at a time. “Gamow was fantastic […]
No matter what the science says, there’s no excuse for cruel behavior to a colleague. Look out into the distant Universe as far as you possibly can, and you’ll come […]
Loop quantum gravity gets the ancient atomist back into the loop, showing how black holes might explode, and that the Big Bang might be a Big Bounce.
When a phenomenon moves from “empirical correlation” to “theoretically explained,” that’s one of the biggest deals in science! “Space and time may have a structure as intricate as the fauna of […]
Falling into a black hole is forever… but could a tether to the outside pull you back out? “Nobody ever did, or ever will, escape the consequences of his choices.” –Alfred A. […]
Why the 2017 Nobel Prize isn’t the end, but the start, of something really, really big. “Wormholes are a gravitational phenomena. Or imaginary gravitational phenomena, as the case may be.” –Jonathan […]
A well-deserved award for the discovery over a century in the making. “Well, I walked into Building 20 and looked in at the various little labs. There was a bunch of […]
Very sure. Here’s how we know. You’ve no doubt heard that the Universe itself has been around for 13.8 billion years since the Big Bang, and that scientists are extremely confident […]
We’ve never seen an event horizon, nor directly imaged a black hole. Thanks to a worldwide effort, victory may at last be in sight. “Never look down to test the ground […]
Risks abound for those plucky few willing to put their lives on the line to populate the Red Planet.
If not for the indeterminate nature of matter, the Sun would never be able to shine. “The bedrock nature of space and time and the unification of cosmos and quantum are […]
Last week, Cassini plunged into Saturn’s atmosphere. Here are the top 6 things we learned from it while it was alive. “Being a scientist and staring immensity and eternity in the […]
Finding a warm-hot intergalactic plasma is amazing! But we still need dark matter just as much as ever. “There are stars leaving the Milky Way, and immense gas clouds falling […]
The results of this study help us better understand how stars are born and how they develop.
Is it conserved? Destroyed? Radiated away? 40+ years on, we still don’t have answers. This article was contributed by Sabine Hossenfelder. Sabine is a theoretical physicist specialized in quantum gravity and […]
A new generation of tabletop physics devices may be the next forefront for breakthrough discoveries.
Physicist Erik Verlinde’s theory successfully predicts the distribution of gravity around 33,000+ galaxies without relying on unobserved “dark matter”.
Why not just put your detectors in place of a giant mirror? “Look and think before opening the shutter. The heart and mind are the true lens of the camera.” –Yousuf […]
