What's The Optimal Temperature For Uranus? (Serious)

Whats the best temperature for Uranus for inhabitable life, also is there anyway to negate the gasses to sustain organisms on this planet?

N/A, No.

Strangest question ever on these forums.

Depends on what sort of life you are talking about.

Life requires several things... including:

1) complex ordered systems for storing data (DNA and RNA for our form of life) which are stable enough to retain their patterns for years, but unstable enough to change almost instantly when new information needs to be stored.

2) chemical reactions that generate enough energy for metabolism and motility, but not enough to destroy the patterns mentioned above.

3) the ability to transfer or reproduce the information patterns almost perfectly (but not 100% perfectly, or evolution ends).

Here on Earth, chemical reaction based on Carbon compounds (especially nucleic acids) fit the temperature range. On hotter worlds, they would be too unstable. On colder worlds, they would not be unstable enough.

Uranian life would require a chemical basis that would not work on earth, because the chemicals would be too reactive in our temperature range... the lower temperatures on Uranus would make them just reactive enough to support life.

Not sure what you mean about negating the gasses. Here on Earth, we breath an Oxygen-rich atmosphere, and metabolize it to oxidize the reduced (meaning: Hydrogen-rich) compounds in our food. On Uranus, any natural form of life would breathe the reduced (Hydrogen-rich) atmospheric gasses like Methane or Ammonia, and metabolize them with Oxegen-rich compounds in their food... just the reverse of our own energy cycle, but with the same result... energy plus water.
