I’m an engineer that makes those drawings and I can’t dispute this at all.

We would probably only ever get a real image like this if humanity becomes a multi-galactic race. And I agree, the odds of that are close to zero and sad.

The Cygnus Loop is a spernova remnant in the Cygnus constellation. The nebula is massive, much larger than the full moon in the sky. It is about 120 light years in diameter and over 2,000 light years away from the Earth. This data is a false color image consisting of Hydrogen and Oxygen emissions along with true-color RGB stars. Was taken over most of the month of July 2023.

This shows how effective nuclear weapons are as a deterrent. The threat of them is the only thing keeping the war going this long.

Same reason you see chevrons on the back of some modern turbofan engines

Sounds like these workers are extremely important and the company is dead in the water without them. The company should be well motivated to provide them a great deal they are happy with right? /s

What about tipping points? I hear about ice cover, ocean currents, and other systems where once we get past a tipping point, additional warming is self sustaining. At that point it doesn’t matter if we have our brakes on, we’ve gone over the cliff right?

Good. There’s no room for partisanship when it comes to ethics and accountability.

Nothing like subverting the will of your own constituents
