A hypothesis is proposed whereby neutral tachyons would be particles created pairwise (or in more numerous groups) in a strong gravitational field near the cosmological singularity. The tachyon would be a nonstable particle. It would accelerate in response to its spontaneous emission of gravitational radiation, and, reaching infinite velocity over a finite distance in finite time, it would annihilate with its group partners. At this instant it would have zero energy; thus the energy of tachyons would never be negative, and the stability of a vacuum would not be violated. If the tachyon mass is comparable to or greater than the mass of baryons, its lifetime would be very much shorter than the age of the universe, thereby removing the causality paradox.
