This meant that the Higgs field still had a high value as particles and anti-particles were colliding and annihilating one another.
Shortly after inflation, the universe's growth slowed and the two kinds of particles (which are perfectly opposed in mass and charge and effectively cancel each other out) began colliding and annihilating one another.
But, they say, a better and more enticing explanation for the excess is that the particles are being spit out of the fireballs created by dark matter particles colliding and annihilating one another in space.
In the top panel we see the stable and unstable solutions annihilating one another as h is increased, as expected.
The primary deterrent to war is the chilling notion of mutual assured destruction, which requires Washington and Moscow to maintain sufficient nuclear firepower to annihilate one another.
Depending on the nature of the inhomogeneities, wave front fragments may annihilate one another, producing a nonsustained arrhythmia, or may spawn new spirals (multiple wavelets), producing fibrillation and sudden cardiac death.
According to some theories, these particles could decay or even collide and annihilate one another, producing a telltale gamma-ray signal in the process.
Dark matter particles floating in the halos around galaxies would occasionally collide and annihilate one another in tiny fireballs of radiation and lighter particles, theorists say.
If neutrinos and antineutrinos are the same particle, in some instances of this rare event the two neutrinos/antineutrinos would annihilate one another inside the nucleus and experimenters would see no antineutrinos emerging.
Such WIMPs floating in the halos around galaxies would occasionally collide and annihilate one another in tiny fireballs of radiation and lighter particles, the theorists Michael Turner of the University of Chicago and Frank Wilczek of M.I.T. suggested in 1990.
If Nature were perfectly balanced then nothing of 'solid' substance would exist; equal amounts of matter and antimatter would have annihilated one another and our universe could only be filled with light.
