I really wish "the consensus to leading scientists" would just stop propagating the deception of "earth is a sphere". Even the most rudimentory research reveals that this place in space we occupy is flat.

We used to call the notional "opposite planet" by the name Nemesis. Pretty sure it's not there.

And this in an environment where we are all supposed to be in electric cars by 2030... That's seven years away. Where's all this electricity coming from? How is it to be transported? I have turned down what I can. The kitchen, heated only by the cooking of food. The den, unnocupied, unheated. The basement, unheated (seems to self maintain at around 40). The living room, moved temperature sensitive critters in with us, and it's staying warm. Bedroom, still heated, but turned low. It's amazing what two or three blankets and a nice thicc wife can do!

Suck, squeeze, bang, blow. The basic cycle of an internal combustion engine. So, the universe may be in the midst of millions upon millions of cycles. So? Can't know, don't care.

Look closely at the next Subaru you see. スバル = Subaru = Cassiopeia

We might not ever. Robotics continue their incredible advances. We may never need to send humans. At least, not until we can do it easily...
