Submission + - Yes, Virginia, Black Holes Exist!

StartsWithABang writes: "And so what these three papers, in tandem, have done, is demonstrate that there is no firewall and that the resolution to the firewall paradox is that the first assumption, that Hawking radiation is in a pure state, is the one that’s flawed.

You won’t read about this in the popular write-ups because it doesn’t have a catchy headline, it’s complex, and it’s not work by someone that’s already very famous for other work. But it’s right. Hawking radiation is not in a pure state, and without that pure state, there’s no firewall, and no paradox.

There is still an incredible amount to learn and understand about black holes, event horizons, and the behavior of quantum systems in strongly curved spacetime, to be sure, and there’s lots of very interesting research ahead. These findings arguably raise more questions than they answer, although at least we know that black holes won’t fry you when you fall in; it will still be death by spaghettification, not by incineration!"

Listen to what the best science has to say, not just to the most prominent scientist who says things.

Comment Re:Pre-Roasted Coffee (Score 1) 76

Invalid argument. The coffee is chemically active so the flavor CHANGES after a short amount of time. If you have not had coffee just roasted and tried it over a period of days you would not know the difference. The easiest way to describe is that it gets mellower and less sweet. As to weather it really makes a difference that is subjective. If trying to brew the PERFECT cup of coffee however then it definitely makes a difference. Coffee being discovered in Ethiopia tends to give enormous credibility to the practices and methodology of Ethiopians regarding coffee. The initial period of 12-24 hours for degassing, standard practice among europeans is ignored since all the coffee is used right away. This mostly applies to bubbles that foam up during brewing but coffee that has not degassed has a wilder flavor also. In practice at home I usually use it within 2-4 days but after 5-7 days it is not the same. as before of directly after the 12-24 hour period; first getting mellower and then towards bitter.

Comment Pre-Roasted Coffee (Score 1) 76

What are your thoughts regarding pre roasted coffee versus roasting at home? (I personally roast at home with a popcorn popper and find that it produces better results at a lower price. The founding belief being that coffee being a chemically active substance after it is roasted makes it theoretically impossible to store roasted coffee and retain the original flavor since it can't be stored at absolute zero.)

Maybe it was an illustrative device but you would not need to use lead. The standard practice is to use a Faraday bag or case which could be made of lots of different materials including lead as long as it is electrically connected to the closure. Lead is used for radiation shielding but for electro magnetic shielding a Faraday bag or cage is used...
