Given that our first direct detections confirming the existence of black holes only took place in this century, humanity can be forgiven for not knowing a few things about these mysterious cosmic objects.

We don’t even know everything we don’t know – a fact that’s been made evident in a new discovery. While running equations for quantum gravity corrections for the entropy of a black hole, a pair of physicists found that black holes exert pressure on the space around them.

Not much pressure, to be sure – but it’s a finding that’s fascinatingly consistent with Stephen Hawking’s prediction that black holes emit radiation and therefore not only have a temperature but slowly shrink over time, in the absence of accretion.

“Our finding that Schwarzschild black holes have a pressure, as well as a temperature, is even more exciting given that it was a total surprise,” said physicist and astronomer Xavier Calmet of the University of Sussex in the UK.

“If you consider black holes within only general relativity, one can show that they have a singularity in their centers where the laws of physics as we know them must break down.

“It is hoped that when quantum field theory is incorporated into general relativity, we might be able to find a new description of black holes.”

Filmed from the final year of President Obama’s presidency to the present, the new documentary ‘Civil War,’ airing Sunday at 10 pm ET on MSNBC, examines how differing narratives about this pivotal, historic event shape our beliefs to this day. Joy Reid speaks with the filmmakers, Erika Dilday and Rachel Boynton.

DAOs, or decentralized autonomous organizations, are essentially businesses, charities, and other operations that operate decentrally via a blockchain.

A DAO is an internet-native organization that uses rules embedded in blockchain code to govern the behavior of the organization and its members.

Many DAOs leverage existing decentralized networks like Bitcoin or others in the DeFi space.

Your TV’s picture settings menu can be overwhelming, but that doesn’t mean you can’t make a few small changes to make watching your favorite shows, enjoying 4K HDR movies and playing video games even better. With a couple easy tweaks to your TV picture settings, colors can look more accurate, motion can look more natural and brightness can be adjusted for comfortable day and nighttime viewing. It only takes a few seconds to change your picture mode. You can even give TV calibration a try, if you want more options for optimal TV watching. 

A word of warning before we begin: Picture setting names are all over the place. A setting one TV-maker calls “brightness” could control something totally different on another set, for example. We tackle a lot of the variations below, but we can’t account for every TV-maker, especially on older models, so your mileage may vary.
