Story time: The Sun.

Never knew how much I needed a daily dose of uncle bob

new single Stargazing just landed

This reminds me of a graduate study I read about years ago that analyzed the cost of brute-forcing a 256-bit key in terms of power rather than time, based on the Landauer limit that states a theoretical minimum power required for flipping a binary bit. The guy postulated a very simple prototype that merely flipped a single bit back and forth between one and zero, 2^256 times. Put it out beyond the heliopause somewhere to get it really close to absolute zero, so the Landauer limit is as small as possible. Such a "computer" obviously can't do any codebreaking, but at least it'll serve to put a lower limit on the power required. The guy figured out that if you could capture all the power from an average supernova and feed it into the bit flipper at a rate it could handle, it would be enough to power about 2^192 bit-flips. This means you could power it through the entire sequence just by capturing all the energy from a mere 2^64 (~10 sextillion) supernovas. And of course, once we're done with that, we can start building a computer that can actually try real encryption keys. Bada bing, bada boom, pretty soon we'll be able to break into anybody's Ethereum wallet, as long as we can accumulate enough supernovas.

delighted every day when this drops.

To play it safe I will plan my move to mars in 200 million years or so

There's an additional interesting detail: the Earth has a lot of land mass in the Northern hemisphere and a lot of water in the Southern hemisphere. If the Earth didn't have a tilt of 23.4 degrees then we would have had terrible a temperature asymmetry. We are saved by the tilt.

well. heh…

Or we move the sun

Maybe if we develop some kind of technology that controls the space distortion (since space is describe like a fabric but is more like a fluid) it would be more simple than move the earth, maybe refueling the sun is another alternative (I know people would say that amount of fuel need is immense, there's all other sort of problems that needs to be solved, but we have plenty of time for that).

Always learning something valuable from you, Uncle Bob @unclebobmartin . Thanks for sharing.

Really enjoyed this Bob, well done 👍
