  Astronomer here, not necessarily. Generally, heat death just means entropy goes maximal, as in everything is as spread out as it can be and the heat everywhere in the universe is the same.

  Not sure if on those time scales all gets sucked up by BH

  Sure. Generally, it is a marker for life as we see it being produced by living organisms on Earth and it also should vanish quickly from atmospheres if it is not replenished. However, as you correctly put it, there may always be a non-biological explanation as well for any of these marker. So far I know, DMS has no non-biological explanation so far and is seen as a biological marker still.

  Alas, the possibility of it being proven non-biological or even (as happend here) not a real detection makes it even more important to get more data and be very careful about the statements made from it than as otherwise those statements and/or connected papers have to be corrected/retracted.

  Astronomer here, the “life detection” on K2-18b was dimethyl sulfide (DMS) and which is and remains a marker for life. What you get from the James Webb Space Telescope (JWST) is raw data that needs to be treated and calibrated to some extent to be usable in scientific study. This is called data retrieval.

  However, the lead scientist on this paper claiming they found DMS basically used his own very specific way to do it and found very very weak signals in that way. Other scientist tried to both reproduce it in the way he did it and also with their ways to retrieve the data, but couldn’t find anything. So it turns out, it was simply a misdetection.

  I guess that is one of many applications. Also strong magnets, levitation (that is more funny or futuristic depending on application)

• ⁨Comment⁩ on ⁨Black Holes⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  I think you explain it pretty well, but one thing to add. Due to the General Relativity and thus spacetime it is actually not directions that all point toward the singularity, but as soon as you cross the event horizon all of your future becomes the Singularity, not as a point in space, but a point in time

  What are its advantages in comparison to Heroic?

• ⁨Comment⁩ on ⁨The Plane That Crashed Yesterday Was the Same One a Dead Boeing Whistleblower Warned About⁩ ⁨⁨4⁩ ⁨months⁩ ago⁩:

  True, but that is what the whistleblower Warner about. He said the planes would fail randomly after around 10-12 Sears approximately.

  He was a quaility check engineer at the assembly lines where the workers were forced to assemble too quickly which caused a lot of small foreign bodies (residue) to enter components with wiring that would degrade due to this.

  He also said that would degrade those components much faster than expected and told to the airplane operators causing less checks and earlier failure (than was told by Boeing)
