Likewise, if black holes act like information mirrors, as Hayden and Preskill suggested, a particle falling into a black hole would be followed by an antiparticle coming out — a partner with
the opposite electric charge — which would carry the information contained in the spin of the original particle.
He went on to assert that every particle has a mirror - image antiparticle with nearly identical properties, except for
an opposite electric charge.
The most recent addition to the tour, discovered just last year, involves what appears to be a giant plume of antimatter — a fountain of particles identical to ordinary matter except that they have
the opposite electric charge — shooting up from the core and straight out of the disk of the galaxy as far as 5,000 light - years, where the antimatter jet meets clouds of ordinary matter, and both are annihilated in a burst of energy.
Not exact matches
When voltage is applied to the capacitor,
electric charges of equal magnitude, but
opposite polarity, build up on each plate.
Unlike an
electric field, which can be obstructed by any material that has an
opposite charge, gravity can't be blocked.
That imbalance pushes oppositely
charged particles in
opposite directions to create a powerful
electric current.
But adding parallel magnetic and
electric fields introduces a chiral preference: The magnetic field aligns the spins of the positive and negative particles in
opposite directions, and the
electric field starts the oppositely
charged particles moving — positive particles move with the
electric field, negative ones against it.
(If the magnetic field orientation is flipped relative to the
electric field, the preference would be for left - handed particles, but still with
opposite charges separating.)
If a particle has other attributes (such as an
electric charge Q), then the anti-particle has the
opposite attributes (or a
charge of - Q).
