Is immortality mathematically impossible?

632 views

A couple of years ago, there was this information flowing around on the internet that “immortality is mathematically impossible”, and as an average consumer I just accepted it. Today, it randomly clicked me that I should ask why.

Q1: Is this claim even true? Because we already know that immortal jellyfishes exist and they can reverse aging (hopefully I’m not wrong here).

Q2: How does math play a role in this claim? (really curious about this one)

Lastly: I don’t know if i should flair this post as ‘Biology’ or ‘Math’?

You can have an individual organism that just keeps repairing itself or replacing itself, but that all takes energy. Life takes energy, and there’s only a finite amount of usable energy in the universe. Even if the only living thing in the universe were a single immortal jellyfish and the material required for it to sustain itself, it would eventually use up all the energy and it would no longer be alive.
