If you learned anything in this video, let us know what it was.
When making wishes, always add a requirement that the wish should cause no results that you would view as bad?
Without watching the clip, Iâd say gravity would be significantly higher, so the moon would revolve around the earth faster. I donât think it would affect the year much, since the sun is still significantly more massive. The planet would probably be smaller, due to the higher gravity. Life wouldnât have evolved (or would cease to exist). No atmosphere means no protection from UV. I doubt it would have a magnetic field, because radioactivity I think would be lower, so the core would not be liquid, thus not swirling and causing a magnetic field (but Iâm not sure about that). Thus hard radiation and particles from the sun would bath the planet.
OK, I watched the video. Really cute animation. I like the narrator. And it sounds like they did a lot of research. The main thing I learned is that if Midas touched the Earth, only the solid bits would turn to gold, leaving the oceans and rivers and whatnot liquid.
TIL that king midas is a klutzy planet-killer, no matter how the conversion to gold happens.
Supermassive blackholes from supermassive stars.
If there were such stars, they should have exploded in a special sort of supernova, and we should be able to detect these supernovae using the James Webb Space Telescope.
I learned that scuba divers can comfortably breathe air at 150°C while everything bakes around them. Although I mightâve misunderstood that part.
I do feel like they may have missed two effects in their analysis:
- The transformation is shown as spreading outwards from the point of contact, but the results they gave depended on an instantaneous change. The speed of the transformation spread would have an impact on how quickly everyone died.
- I have to wonder if the âspongy goldâ option would compress into solid gold quite that way. Even if theyâre entirely empty, would having all of those voids throughout the structure have an impact on the speed/extent of the compression?
(Yes, I put too much thought into it. But I already gave my quick-and-easy answer. )
Snow goons gold bugs are bad news.
Good point. Would everything collapse so fast (with enough kinetic energy) to form a neutron star? Or black hole?
Reminds me of cavitation, where vapor bubbles caused by sudden low pressures in fluid collapse suddenly, causing jets that can damage propellers (and mechanical heart valves). The collapse can also cause plasma formation due to the intense heat â and some people used to think fusion could result. But thatâs been pretty much discredited.
But could fusion happen with planet-driven cavitation-like behavior? That might lead to:
79Au + 79Au > Element 158 > ??? > large boom

I donât have access to the paper, but it looks like thereâs a lot of argument about the dating of the Alamo Wash dinosaurs.
Most recently:

Hrm.
As interesting as the simulation hypothesis is, this article seems to boil down to:
1: a simulation would have maximums imposed on it by the hardware it is on
2: a maximum speed of light exists
3: therefore, this proves we must be in a simulation
I feel like this begs the question, though, by trying to extrapolate maximum limitations of simulations within our universe to the universe itself. But logically, this would mean that a universe that is not in a simulation would have absolutely no similar maximums⌠and you would have to wonder why, then, the hardware within that universe (supposedly running our simulation, or a parent simulation) would be required to have these maximums that are then imposed on the simulations within it?
so, itâs a sort of planetary âwhen one door closesâ kind of thing?
âThe lesson learned here is that under rapid disturbances⌠tropical ecosystems do not just bounce back; they are replaced, and the process takes a really long time,â said Dr Carvalho.
