- TeMPOraL 3y agoOkay, can we use it for cooling like in Sundiver by David Brin[0], where people (IIRC) used lasers to keep themselves cool while, as per title, diving their ship into the Sun? -- [0] - https://en.wikipedia.org/wiki/Sundiver https://en.wikipedia.org/wiki/Sundiver
- SAI_Peregrinus 3y agoLasers are often used to cool atoms & molecules to extremely low temperatures[1]. Bose-Einstein condensates are made via laser cooling, and it's commonly used in quantum entanglement experiments since it can get the involved particles closer to absolute zero than other methods.

- eru 3y agoNo, not like that. Sundiver makes a mockery of the second law of thermodynamics.
