Comment Precision and Relativity (Score 3, Informative) 31

Yes, this is proof of concept stage. The key issue with the laser approach is not just power, but aiming precision. The better they columate the beam to focus the transmitted power, the better they need to aim the beam to actually hit the receiver. A deep space craft is only so large, and 200 inch telescopes are also a tiny target to hit at these distances. The mass curvature of space and the motion of objects need to be accounted for, as distance adds signal delay.

I bought a SteamDeck because I wanted to play some games that normally required a Microsoft-ridden PC to play. They use a very similar immutable approach on the SteamDeck, making apps more like game cartridges and maintenance as easy as choosing between public and preview update streams. For Grandma who keeps getting p0wnd by banner scams, an immutable Linux PC with a bog standard screenshare could also be a relief to the IT Support grandkids.

The Vela pulsar is said to have a surface diameter of 12 miles. So, any point on its surface along the rotational equator, assuming rigidity, mass is moving hella fast. (2 pi (6 miles)) / ((1 / 11) seconds) = 667379 m/s That's about 0.2% of C, vs a point at its rotational pole. It's roughly 4x the fastest manmade object, the Parker probe, reaching 148000 m/s briefly while it did a gravity slingshot maneuver.
