In the late 1980s I was a passenger in an airliner at the gate in the Miami airport when I heard a horrendous continuous noise. It came from a taxiing Concorde. I am not going to claim that it was using afterburners, but I agree with the gp that the Concorde was loud.

Transport by earthworms?

What you say is true regarding motion. But even if you are stationary, the Coriolis is acting on the blood flowing in your arteries and veins.

Even if I didn't look outside the window, I wonder how my circulation system and sense of balance would adapt to a significant Coriolis force acting on my blood as it is pumped around my body.

It would depend on the weather pattern prevailing if and when radioactivity would be released. Looking at plots from the 00z March 4 GFS meteorological model dataset, the parent is, for the time being correct, it looks like the airflow is currently toward the east in that region.

We should think through what is going on here. If this technology were to get out of control, we can expect there to be major repercussions both in terms of scientific research guidelines and possibly society at large. Are there other examples of dangerous things that escaped from laboratories? Sure, we have secure facilities to do this work, but how secure is secure?
In order not to muzzle scientific progress, which could happen if a societal backlash resulted from a mishap, it probably is time to see major efforts made to develop and study ecosystems in space-based settlements, and then to do the more dangerous experimentation in those facilities so that our environment on Earth is not placed under serious risk.

Think of many invasive species, which were introduced because there were so many wonderful things they would accomplish. We now regret our decision to introduce them.

Like it or not, all of our "non-social" sciences, including computer science, have social implications. My field, atmospheric science, is a prime example. We should not carry forth our activity without considering the social implications of our research. Regarding the implications of AI, I'd recommend a book, published just before the pandemic, by Amy Webb entitled "The Big Nine: How the Tech Titans and Their Thinking Machines Could Warp Humanity." I don't agree with everything promoted here, but do think this contains a lot of good information.

If we go to permanent standard time, those of you who would rather have DST, you can get closer to that experience by choosing to live in the far western part of a time zone. For example, for the U.S. Eastern time zone, Georgia and the lower part of Michigan would work well.

The temperature and pressure at which water boils are interrelated. If you access a "steam table" from an engineering thermodynamics textbook, look at a table entitled "properties of saturated water, temperature table," you will find an entry called "saturation pressure." That is the pressure at which water boils at that temperature. If you look at something near your body temperature, say, 38 degrees C, the pressure is about 0.066 bars (or about .066 atmospheres). If you are in the upper atmosphere or in space with no pressurized suit and the pressure is below 0.066 atmospheres, your blood will boil.

This is not a complete answer to this question, however. There are concerns about bubbles of nitrogen ("the bends") due to rapid depressurization, etc. that also need to be addressed.

Who's going to build the coal-powered power plant to supply electricity for the chargers?

Why is this being reported now? The ozone depletion is a springtime phenomenon. The high exposure to UV at high latitudes would be experienced during the late spring and summer.
