If there are particles in the vacuum which obey the heisenberg
relation e x t = h bar, then if they have a mass of 10^- 68 kg-an
energy of 10^ - 51 J-
they cannot lose this energy before 10^ 17 seconds have elapsed -
about the current age of the universe.When they lose their energy they
could do work.
Could they slow down an accelerating universe?
If these particles had a smaller mass this would give us the maximum
time the universe can expand for.And allow us to calculate its minimum
temperature.
Any thoughts on this?
