Falklands ship-loss conspiracy claims fail on shipbuilding reality

Could HMS Invincible have been sunk and secretly replaced after the Falklands?

He rejects the theory, noting that ships cannot be built that quickly, hundreds of deaths could not be hidden, and an extra carrier could not be concealed.

The theory returns regularly, but it does not survive practical scrutiny. A replacement carrier could not have been built on the proposed timeline. Concealing the construction and substitution would have been equally implausible. The implied loss of hundreds of people adds another event that could not realistically have been hidden.
