Fortunately, a crucial step in the Harlow-Hayden approach to the firewall paradox, concerning the time available for decoding of Hawking radiation emanating from charged AdS black holes, can be made to work without relying on the unknown physics of black holes with extremely high temperatures; in...
Last year itwas shownthat if Hawking radiation is in a pure state, then either it cannot radiate in the way required by thermodynamics, or it would create a firewall of high energy particles near the surface of the event horizon. This is often called the firewall paradox because according ...
First quilter in space challenges students, crafters to stitch the moon 'Star Trek: Lower Decks' Season 5 episode 5: What's the problem with Starbase 80? 'Hawking radiation' may be erasing black holes. Watching it happen could reveal new physics.MORE...
Buddy of mine and I were discussing Stephen Hawking's "warning" to mankind dating back to a 2010 Discovery Channel comment that aliens we encounter may not be particularly friendly and meeting an alien species would in all likelihood be catastrophic to the human race. You, your buddy, and St...
When an atom is unstable, it means that it doesn’t have the right number of protons and neutrons in its nucleus. This can happen when the atom has too many or too few of either. When this happens, the atom releases radiation in an attempt to become stable. This radiation can be harm...
This unfortunate energy story is essentially a physics problem. Energy per capita and, in fact, resources per capita, must stay high enough for an economy’s growing population. When this does not happen, history shows that civilizations tend to collapse. ...
The engage and disengage events are spacelike separated, so they don’t actually have an order. From (any one of) the proper frames, the disengage event can happen first (right half of the image above). When that’s the case you find that: ...
The lack of atmosphere would also mean you’d be badly poisoned by radiation from the sun (which would look 2.5 times bigger in the sky than it does on Earth). On the plus side, Mercury’s gravity is only 38% of Earth’s, so you could jump around in a silly way as you died ...
If this theory is true, the big question is, Where in the timeline does the Great Filter occur? It turns out that when it comes to the fate of humankind, this question is very important. Depending on where The Great Filter occurs, we’re left with three possible realities: We’re rar...
Yet even Hawking doubts that his set of equations can yield a complete resolution to themystery of existence. “ What is it that breathes fire into the equations and makes a universe for them to describe?” he plaintively asks. “Why does the universe go through all the bother of existing...
