So is it confirmed that this was a Chinese spy balloon?

An F15 has shot down a orbiting satellite in the past, so I wouldn't say that's a good definition.

I count only 19 stars. The rest are galaxies. Wild

meh, it's not like the US had to purchase the missile specifically for this shootdown.

It was basically just a big training exercise for the US military.

The Kármán line at 100km is a fairly agreed upon estimate.

But it feels wrong to let anything just hover in place over one's airspace - it might be an idea to include a requirement for the object to be at an orbital flight speed.

Using balloons is an excellent way to hurt your rivals/enemies. It costs them far more to destroy a surveillance balloon that it does to build one and fly it over their territory.

Watching her show would be the worst kind of torture. I think it was specifically called out in the Geneva Convention as being too inhumane.

did you read the article?

Something is too low when a jet can shoot it down.

I believe it’s considered about 60 miles (100 km) above the Earth. That’s where conventional aircraft don’t have enough atmosphere to fly.

If you commit a crime on Miranda, they read you your Earth rights.

The only thing Nancy Grace should have named after her is a form of torture equivalent to watching her reprehensible show.

But if you had 500, think of all the TV shows you could catch up on! Lol.

On a more serious note, working until your 70 just to enjoy the last 10 years before you start getting frail, is kinda shitty. If we lived for 500 years, I could work till 80, and have enough retirement $$ to last the next 420 (heh). That would be like retiring at age 16 with a life span of 100. Imagine being able to retire at 16 and just enjoy the rest of your life to the fullest.

I think it's because the image is a combination of images taken at slightly different angles, and the position of the diffraction spikes is dependent on the telescope roll angle.

That area of sky was chosen because there are more images of galaxies than there are galaxies there. The lensing foreground cluster creates multiple images of the same galaxy. Edit: I see a third.

Dyson swarm, antimatter, kugelblitz etc.

This is such a far futute solution that there are a ton of ways to produce a ton of energy out of various violent cosmic objects...

Where exactly would you get enough energy for something like that

Social progress is being held back by the work of Adam Smith, and the Puritan belief that idle hands are the devil's hands.

In 1982, America threw out 40% of the food it served. In the same year and for 3 decades, America alone spent as much celebrating Christmas as it would take to feed the world per capita a very rich diet for a full year. That's just one example. We are a wealthy species and our society does not reflect it.
