[2] Tipler has written books and papers on the Omega Point based on Pierre Teilhard de Chardin's religious ideas, which he claims is a mechanism for the resurrection of the dead.

His work has attracted criticism, most notably from Quaker and systems theorist George Ellis, who has argued that his theories are largely pseudoscience.

[7] With computational resources diverging to infinity, Tipler states that a society in the far future would be able to resurrect the dead by emulating alternative universes.

In that book (and in papers he had published up to that time), Tipler had offered the Omega Point cosmology as a hypothesis, while still claiming to confine the analysis to the known laws of physics.

[15] Scholars are also skeptical of Tipler's argument that if an immortal entity with advanced technology exists in the future, such a being would necessarily resemble the Abrahamic God.

[24] Michael Shermer devoted a chapter of Why People Believe Weird Things to enumerating what he thought to be flaws in Tipler's thesis.

[26] In a review of Tipler's The Physics of Christianity, Lawrence Krauss described the book as the most "extreme example of uncritical and unsubstantiated arguments put into print by an intelligent professional scientist".

Polkinghorne himself asserted that the hope of resurrection "lies not in the curiosity or calculation of a cosmic computer, but in the personal God who cares individually for each of His human creatures".
