I wouldn't call this observatory a "sun probe" because the L1 point is still 0.99 AU from the sun. For comparison, the Parker Solar Probe is expected to reach 0.046 AU.
I think you're confusing "galaxy" with "solar system", but presumably he could pick another suitable star, accelerate to light speed (or however fast he can go) in that direction, take a nap, and then use the destination star's power to slow down.
A lot of it's going to Europe as a replacement for Russian gas.
The main problem is that everybody's been switching from coal to gas instead of wind/solar/nuclear, as if drinking more water makes it ok to piss in the pool.
The hole would be 0.5m wide and >1000m deep, backfilled with bentonite clay and concrete. At the bottom, the path curves back upward, so waste is not stored at the bottom.
Even if geology doesn't collapse the hole, it's hard to imagine material climbing up through 1000m of clogged pipe.
What's the point of sharing your baseless speculation? I hope you're wrong, and that they're building passive safety systems without making any significant mistakes, but the amount of research required to refute your ideas would be enormous.
They should just turn the back of the plane into a ball pit and chuck all the kids back there before takeoff. The larger ones can take care of the babies.
Did I miss India annexing Europe and Canada?
