Harvard-Scientists Say They May Have Detected Dark Matter Annihilation
As you already know that gravitational waves have been
discovered and it is a top milestone. Now the next mystery to be solved is Dark
Matter. Felt but not seen, scientists don’t even know what dark matter actually
is—is it essentially a type of matter, or is it presently the gravitational
effect of mysterious higher-dimensional objects? Many astrophysicists incline
to the former view, and they even propose that it shares—along with gravity—the
matter-antimatter dualism of “normal” subject (that is, atoms and all the
living things, planets, stars & galaxies they form).
This theory suggests
that the presence of “weakly interact massive particles” (WIMPs), and if right,
the annihilation of matter-antimatter forms of these WIMPs would yield a
predictable signature. Which is exactly what a group of astronomers from the
Harvard-Smithsonian Center for Astrophysics (CfA) claims to have found.
Astronomers studied the center of Milky Way Galaxy, an extremely energetic
region—packed with exotic astrophysics, for instance a supermassive black hole,
many pulsars, frequent supernovae, and energetic star configuration.
But the astronomers concentrated on the signature of high
energy gamma radiation originating from the huge core of Milky Way, and in
particular, its scattering. Theoretical dark matter models counting WIMPs
suggest that, if the particles are actually annihilating one another, the cores
of galaxies would be a decent region to look; the gravitational concentration cause
dark matter, rxactly like normal matter, to specially sink into these region.
The CFA astronomers had to keep out the competing
theory—that the energetic photons are formed by fast-spinning pulsars. If the
latter idea were true, the gamma rays would cluster in areas where stars are
made; but the real signal is much more disperse, which settles well with the
distribution projected by dark substance models.
This discovery still expects approval, but if established,
it would be a giant step forward in our understanding of what our universe is actually
made of.
