Mass is not increasing in the frame of reference of the ship, so no, it will not collapse into a black hole regardless of how much energy it received externally (e.g. laser beam from Earth) to accelerate closer to the speed of light.

It seems they intended to make a pause after "but". For that purpose "..." instead of the comma, would actually fit better.

Depends on the phone, high-end phones (iPhone obviously, but also Samsung S XYZ, et al.) have quite good "vibration" these days, since it is produced by more sophisticated mechanism [1] than just rotating motor. [1] https:/&

Indeed, glaciers are literally ice-rivers [1], they flow from mountains down. Melting downstream near the sea/ocean will accelerate their disappearance and yield to global oceal level increase. Ronne Ice Shelf is like an ice-gulf, melt

Update: since Ronne Ice Shelf, from which A-76 separated, has ice thickness of about 150 meters [1], if A-76 has the same level above the water as the Ice shelf, about the same surface underwater (which likely is not the case, but good enou

No idea. But the interesting fact is, that regardless of the depth (assuming that iceberg was afloat already before the separation), it will not increase ocean level at all. Melting of on-land snow and ice/glaciers leads to global ocea

Well, no, pulsars periods drift due to change of alignment and emission process over time. Thought special and general relativity will drive any "global/solar system/galaxy"-wide precise time useless on long term anyway.

Well, obliviously they do have a comprehensive model since they are able to: 1. start the most advanced rocket engines (full-flow staged combustion cycle engines [1]) 2. ascend to 10km gradually shutting down (and throttling) engines to kee

Actually the computing power of Ingenuity surpasses one of the Perseverance rover (and probably by a lot). The rover has a radiation hardened RAD 750 CPU (based on PowerPC 750 architecture, which was introduced in 1997 to compete with Intel

During disassembly what surprised me the most was that the back plate is really rigid, since that plastic is reinforced with a metal plate. Instead of fixing that plastic-metal assembly with excessive use of glue, some 6-10 screws on the pe

Interesting, a cup of sweet tea killed my A1243. Water got inside and shortened some pads or tracks, since pressing one key instead generated 3 or 4 others. I tried to dry it with rise and silica gel for weeks - didn't help. Then I tri

Actually A1243 has an internal USB hub with two ports on both sides of the bump underneath. Those ports are very handy for Logitech wireless adapters: wherever the keyboard is plugged to the mouse comes with it.

I wonder why can't they confirm the fact. Even if it is illegal, noone will go in jail for that, some fine and thats it. Plus given that it is a tourist atttraction now, the fine would likely not be that high. Bad excuse, I guess.

Yes. The drone was accessing the tower where cable has snapped before, so other cables there were under highest load. The fact that drone was there in the "right" moment likely just a coincidence, probability of which was increase

The dish has a phased array antena already, so it is already tracking the satellites. Likely such approach, unless integrated in a bigger dish of some kind to increase signal to noise ratio, already is much more precise and faster than any

1901 telegraph submarine cables [1] were more straight for a similar route. Likely because it was essential to make them as short as possible going underwater, so most of them were going from Ireland to Newfoundland. [1] https://

The extra distance for NY/NJ-Bristol cables to cover is "just" ~400-500km (extra ~7%), plus if you look at ocean floor map [1] it seems they prefer not to put the cable in the relatively shallow waters of Newfoundland or Nova

Iron has a specific energy of 4.9 MJ/kg (for comparison: wood 18, coal 26-33, natural gas 53.6, jet fuel 43, diesel 45.6, gasoline 46.4). So having ships, planes or even cars powered by burning iron seems to be unfeasible (at least fro

Yes, indeed, though this seems to be an experimental drone. Most common commercially available DJI drones fall if single motor or propeller fails, though in future they may gain such functionality, which would be great for safety. A nice ex
