A burst of energy occurs in some cases but not others, depending on mass and composition: https://en.wikipedia.org/wiki/Supernova#Core_collapse

Yes and no... If you maintain the same f-number then angle of view halves, field depth doubles and the amount of light collected decreases by 75%. To take the same photo on 4/3 as say a FF camera with an 85/1.4, you need two more stops, or a 43/0.7. That would be a bulky and very expensive lens if it existed. The 35-100/2 weighs (and when it was available, cost) twice as much as the FF equivalent 70-200/4, for example.
The system is perfectly fine, if you accept these compromises. FF (and larger) is still the answer if you need or want to gather as much light as possible.
Ver is a US citizen
Not since he renounced his citizenship six years ago.
And was then in 2015, according to Wikipedia, "denied a visa to reenter the United States by the U.S. Embassy in Barbados, which claimed that he had not sufficiently proven ties outside of the United States that would motivate him to leave at the end of his visit, causing fears he might become an illegal immigrant." Hilarious.
I'm not convinced it's an option today either. Adaptive optics work to improve the definitiion of incoming signals but signal power is still lost. They don't "unscatter" the original signal, they correct what remains of the signal at the receiver.
And if a laser beam has been bent up into the sky by the atmospheric conditions, there's not much you can do at the source to counteract that. You could aim it downwards but the earth is probably there...
Facebook is slowly being dragged, kicking and screaming, to running Libra like an ordinary, compliant payments processor — PayPal, but it’s Facebook — or Libra won’t be allowed to exist.
The only interesting things the blockchain parts could do is work around regulations — and there’s no way regulators will let Libra do anything like that.
Libra was founded on Bitcoin dreams — but none of those aspirations will ever happen, because they contradict everything about how finance works in the real world.
If you’ve looked over previous versions of the white paper, you’ll want to read this one afresh, closely.
Just focus on the bits about regulation. Ignore the wild crypto aspirations — because none of those are going to be allowed to happen.
Crypto dreams are tolerated when they’re put forward by weird small-time nutters — but not when they’re coming from a huge company with a continent-sized user base.
"The people that make the software and all the stuff that we use to record are sitting right now trying to figure out how Lars and James [Hetfield] and Kirk [Hammett] and Rob [Trujillo] can make a Metallica record from four different locations in four different states. That's obviously something that we're very excited about."
Literally, there are bands that have been doing it this way for 20 years or more and only congregating for live tours. It's done using a thing called the internet.
The Prime Minister of Australia now Listens and refers to actual science and qualified people in press briefing...Yeah... that's what's so puzzling.
Or perhaps it shouldn't be. He's following the science here because 1) it's politically convenient to do so in this particular circumstance and 2) he doesn't have a choice. Once this is over it'll be back to business as usual for the anti-science brigade. A leopard can't change its shorts.
Space programs live on OTA updates!
Seriously some of the post-deployment hacks that have been performed, either through necessity to save a mission or because improvements have been found, are legendary. Many of them have been covered here.
