Hawking proposed in 2010 that BH can't collapse beyond the event horizon, that there isn't one. https://www.pbs.org/newshour/science/hawking-meant-black-holes

In 2014 Vaz said the boundary is outside the Schwarzschild radius. http://arxiv.org/abs/1407.3823

If they're right, then there's no inside to be trapped in.

Isn't another location

"previous" and "subsequent" locations in space are memory phenomena, High-energy location changes are closer together in memory. Our "time" is a bookshelf of physical events in space, one following another. Of course they're sequential, so it was convenient to 'measure' the 'distance' between the books for purposes of prediction. But we've invented that ruler, then forgot we made it up. Many indigenous people have no 'time', and they manage.

If a one-ton boulder rolls down an Earthly hill in my direction and I don't move, what happens is not a manmade concept. Call it what you will.

Time on the other hand exists only as a useful mental tool to describe change. When I repeat the experiment of going to sleep, when I wake up it's still always now. That experiment -always- produces the same result.

If there's a 'Good Place', then there's one rule of ten that ALMOST EVERYONE ignores. Kings, popes, game hunters and every 'Christian soldier' pretends it's complicated. It's a very simple rule, with 4 words using only 16 letters. A 5-year-old can understand it. There's no escape clause. Ignore it and you'll not get there.

Spying on citizens began back in the early days of the telegraph. It took off big-time during WWI.

COINTELPRO wasn't just spying, it was a Federal program to frighten non-conforming citizens into silence and inaction. Pretty much refined disinformation ... just like today.

There is A LOT of radioactive matter below the earth's surface ... constantly generating heat.

"About 50% of the Earth's internal heat originates from radioactive decay. Four radioactive isotopes are responsible for the majority of radiogenic heat because of their enrichment relative to other radioactive isotopes: uranium-238 (238U), uranium-235 (235U), thorium-232 (232Th), and potassium-40 (40K)." - https://en.wikipedia.org/wiki/Earth%27s_internal_heat_budget

Didn't see that in the article, sounds interesting ... where can I read more?

 

"This road is long, and much of the map remains blank. The biggest problem is drilling miles through hot rock, safely. If scientists can do that, however, next-generation geothermal power could supply clean energy for eons."

Newton's classical observations have stood up well.

If anything, it's quantum that has been poorly treated by generations of explaining-away. The world of the tiny must be predicted with probabilities because there is no way for us to observe it directly. It's not rolling dice ... we -have- to.

While trying out models of what it's doing boggles our minds, our limitations mean we cannot decide whether it's really deterministic. Reality isn't limited that way. (Einstein was right.)

Some astronomers recently took a clever look for whether space is quantized into a 'froth'. They studied monochrome light from stars 18 billion light years away, at redshift z=2.34. They found evidence of quantization into froth in all that time. https://arxiv.org/abs/2001.06016

EDIT: That should have read 'NO evidence of quantization' in 18 billion years of travel.

 

It is estimated that 4 billion tons of cement are manufactured each year. To speed up CO2 uptake, "instead of mixing calcium oxide with sand, they mixed calcium oxide with another mineral composed of magnesium and silicate ions. The heat catalysed an exchange of ions, forming magnesium oxide and calcium silicate: alkaline minerals that react quickly with acidic CO2 in the atmosphere." Far quicker than most concrete, anyway...

Water scouring the surface? Or was it thousands years of wind-blown sand / dust? Dunes have ripples.

There is no water on Mars (not to be confused with liquid CO2) until somebody goes there and drinks some. Anything else is hoping for water to justify the $100billion price tag.

I'd learn to speak zombie. Doesn't take long, it's mostly throat noises. And walk like a zombie, just pretend a horse kicked you in the ass yesterday.

She puts on a good show ... does her promos ... then lambastes Californians because they didn't put out the fire with ocean water. Anyone who said 'Well, duh' to that belongs in her club ... the 'if I can talk really fast I must be smart' club.

For me, any office apps. Never worked in an office, never wanted to. None of that stuff. Even if it's free, if it gets installed with the distro, it's the first thing that gets tossed.

 

Article is a response to the paper:

“THE SUSTAINABILITY SOLUTION TO THE FERMI PARADOX”

https://arxiv.org/abs/0906.0568

 

Estimated heat energy in upper 10km of Earth's crust: 1 million billion Gigawatts

 

The period occured in 2024 between late winter and early summer. "Compared to the same period in 2023, solar output in California is up 31%, wind power is up 8%, and batteries are up a staggering 105%."

Link to the study PDF mentioned in the article: https://web.stanford.edu/group/efmh/jacobson/Articles/Others/25-CaliforniaWWS.pdf

One of the paper's cowriters is Mark Z. Jacobson, professor of civil and environmental engineering and director of the atmosphere/energy program at Stanford University.

 

""Too often over the last decade, courts have dismissed lawsuits against the oil and gas industry by saying that the issue of climate culpability should be decided by legislatures. Well, the Legislature of the State of New York – the 10th largest economy in the world – has accepted the invitation...."

 

"She was given a receipt that said 'plates destroyed.' But for the next four years, Ms. Koorey, 75, was entangled in state bureaucracy and caught in the zeal of “Star Trek” fans ..."

This great article begins with the best Fort bio I've seen, from an abusive father to travelling 30,000 miles when he was 19, to the book which brought him to considerable fame.

Damned if you won't like it!!

"The music industry has a moral imperative to keep its history archived, but we can’t trust it to do so. Old records are falling to pieces, and without proper digital preservation, they’ll be gone for good.

"Incredible music and culture is getting lost forever, even though we have the technology to preserve it."

 

"Earlier that evening, at 7:48 pm PT, Biesk’s son had released into the wild 1 billion units of a new crypto coin, which he named Gen Z Quant."
