According to Tipler,<ref name="Tipler1994b"/> during the collapse phase of the universe, life uses gravitational shear energy by forcing a Taub universe collapse (named after physicist Abraham Haskel Taub), whereby the universe collapses along one axis into the shape of an oblate spheroid by life directing trajectories of mass, thereby creating greater heating along the axis of collapse and hence a temperature differential whereby usable energy can be obtained. The Taublike collapse in one direction, and then another direction (i.e., Mixmaster oscillations) is also used to eliminate event horizons by allowing communication across the universe along the axis of collapse, which is necessary for information processing (and hence life) to continue. This mode of collapse ends (in proper time, as in computer clock time it never ends) in a single c-boundary (i.e., causal boundary) point: the Omega Point. The gravitational shear energy thereby available to life diverges to infinity as the Omega Point is approached. That is, by making the negative gravitational energy go to minus infinity, the positive energy available to life goes to plus infinity, as the total energy of the universe at all times sums to exactly zero, as physicist [[Stephen Hawking]] has pointed out.<ref name="Hawking1996">[[Stephen Hawking]], ''The Illustrated A Brief History of Time'' (New York: Bantam Books, 1996), ISBN 0553103741, {{lccn|96019732}}, {{bibcode|1988bhtb.book.....H}}, Chapter 8: "The Origin and Fate of the Universe", pp. 166-167. Hawking writes:
<p>Now twice zero is also zero. Thus the universe can double the amount of positive matter energy and also double the negative gravitational energy without violation of the conservation of energy. ... As [physicist Alan] Guth has remarked, "It is said that there's no such thing as a free lunch. But the universe is the ultimate free lunch."</p></blockquote></ref>
Some have pointed out that the current acceleration of the universe's expansion due to the positive cosmological constant would appear to obviate the Omega Point. Although physicists Lawrence M.

<blockquote>The [[Standard Model|SM]] provides such a mechanism, which I actually discussed in the last section of the Appendix for Scientists in (<ref name="Tipler1994b" group="q">Frank J. Tipler, ''The Physics of Immortality: Modern Cosmology, God and the Resurrection of the Dead'' (New York: Doubleday, 1994), ISBN 0385467982, {{lccn|93045046}}, {{bibcode|1994pimc.book.....T}}.</ref>, p. 515). This mechanism is the creation/destruction of baryon number by electroweak quantum tunneling. (Baryons are the heavy particles made up of quarks. Examples are neutrons and protons.) In my book, I pointed out that this mechanism would be ideal for propelling interstellar spacecraft, but I did not discuss its implications for the Higgs vacuum, a serious oversight on my part. (An oversight which invalidates the second part of my Fifth Prediction on page 149 of <ref name="Tipler1994b" group="q"/>.) If the SM is true—ALL experiments conducted to date indicate that it is (e.g.<ref name="Wilczek2002" group="q">Frank Wilczek, [http://xserver2.lns.mit.edu/~csuggs/physics_today/phystoday/SMPIII.pdf "Scaling Mount Planck III: Is That All There Is?"], ''Physics Today'', Vol. 55, Issue 8 (August 2002), pp. 10-11, {{doi|10.1063/1.1510264}}, {{bibcode|2002PhT....55h..10W}}.

If the baryons were so created, then this process necessarily forces the Higgs field to be in a vacuum state that is not its absolute vacuum. But if the baryons in the universe were to be annihilated by this process, say by the action of intelligent life, then this would force the Higgs field toward its absolute vacuum, canceling the positive cosmological constant, stopping the acceleration, and allowing the universe to collapse into the Omega Point. Conversely, if enough baryons are not annihilated by this process, the positive cosmological constant will never be canceled, the universe will expand forever, unitarity will be violated, and the Omega Point will never come into existence. Only if life makes use of this process to annihilate baryons will the Omega Point come into existence.</blockquote>
