It's not that it takes hours to "hit." Every photon leaving the sun gets here in its own 8.5 minutes. But one photon will not trigger an earthquake - it would be an accumulation of "excess" photons over time that would eventually trigger an earthquake. So if we detect the rate of photon arrival increasing now, then we can start thinking that there might be an earthquake several/many/24 hours from now.

Right. But it wasn’t photons, it was protons I thought. I was thinking this was on the time scale of solar flares and ejecta

Musk keeps stringing this along by pretending that his startup cost will be less than $10B, but there is no freaking way that's remotely accurate.

So the motive is to ballyhoo and stay in the news to finance his next thing, which in turn will be snake oil for his next next thing?

Is this what Mars is too?

Is he just a bullsh-tter?

That would be disappointing. :-(

Yes and no. Tesla, Mars, and Hyperloop are BS.

SpaceX (you know, the one where their price is legitimately competitive with the market AND there are plenty of paying customers?) - definitely not BS.

I wanted Mars, godd-mnit. :-(

I wanted to see a human being on another planet before I died.
 
I think Elon’s mars push is a grift.

Doesn't mean we shouldn’t push for it via nasa. The moon landing advanced science and engineering by more than we think.

This, although I think Tesla is a bit more legit than Musk haters give it credit for, particularly the battery research arm. His cars do compete for some of the market segment that would usually just get another BMW or a Benzo.

Don’t worry. It’s only BS in that there’s no hope for a business case that would attract (and reward) standard/institutional investors. There’s still a non-zero possibility that Musk will convince enough gazillionaires that they want their name attached to such a project that they will shovel in the literal boatloads of cash it will require with no expectation of a return.

Yeah, Tesla is a tough one to pin down - what is the definition of “success” for them?

In 2019, Tesla sold 368k vehicles, which means that traditional car companies still own 98% of the market (17.1M vehicles) - and took home 100% of the profits.

But maybe Elon is being sincere when he says he doesn’t care if vehicles have a Tesla badge, so long as they are electric. The other manufacturers are certainly paying way more attention to the electric vehicle segment than they used to, but it’s at least debatable whether that would be different if Tesla did not exist.

Finally, battery tech is definitely nothing to sneeze at. It’s hard to state just how important just a 1 or 2% improvement in energy density or efficiency is for the economics of countless other battery applications. However, that probably does NOT include the luxury electric car market, where 1-2% reduction in battery weight or increased range would not be game changers.

Neutrinos from a long-theorized nuclear fusion reaction in the sun have been definitively observed, confirming the process that powers most stars.
 
Remember the whole Cubans are beaming sonic weapons at our embassy we should call it an act of war?

Welp, turns out it was exposure to pesticides used for Zika spraying.

It wasn’t a nice thing. It was cheap sheet metal and foam. Instead of something amazing like a billet of hastelloy, it was a cheap Walmart art installation. Typical of what this country has come to represent. Brilliant at first, garbage on closer inspection

One of the people who found it after the NPS did, said it was a major let down. "Bring your windex if you want a half decent picture." THe thing was covered in fingerprints and grime. The top was covered in blood spots where someone cut themselves trying to climb it.

My guess is the NPS removed it because it wasn't "great", it was embarrassingly cheap and someone was going to get very hurt trying to find it or climb it. IIRC, the NPS also said they didn't want to publish the location because if you got hurt trying to find it, your only option was airlift.

Well you're no fun!!
 
I don't have more time to post my thoughts on this but I wanted to get this out there because for me this is infinitely fascinating on so many levels.

Earth Is Among the Lucky 1%: The Solar System Follows the Galactic Standard – But It Is a Rare Breed

This is only a snippet but a good starting point:

The Earth is not particularly special – the number of planets in the system is what it is all about


What more than being an Earth-size planet in the habitable zone does it take to harbor life? What is really so special here at our Earth and in our solar system? As planet considered, Earth is not special – there are plenty of Earth like planets out there. But perhaps it could be the number of planets and the nature of them. There are many large gas planets in our solar system, half of all of them. Could it be that the existence of the large gas planets are the cause of our existence here on Earth? A part of that debate entails the question whether the large gas planets, Saturn and Jupiter, “directed” the comets to Earth carrying water when Earth was half a billion years old, enabling the forming of life here.

This is the first time a study has shown how unique it is for a solar system to be home to 8 planets, but at the same time showing that our solar system is not entirely unique. Our solar system follows the same physical rules for forming planets as any other solar system, we just happen to be in the unusual end of the scale. And we are still left with the question of why exactly we are here to be able to wonder about it.
