returns to the concept of dark
matter, hailed as the most mysterious substance in the universe
next to dark energy. There’s a plethora of questions astrophysicists
are posing and working to solve in order to get closer to
understanding it once and for all.
What (we think!) we know about dark matter is how much
comprises the cosmos and how it behaves. What we’re still trying to figure out is what
it’s made of and where it actually came from. This issue, you’ll discover that a team
of astronomers at the University of Houston, Texas, and the University of Melbourne,
Australia, has an idea in mind – it could have been forged by ballooning cosmic bubbles,
which led to its abundance in the universe.
The team reasons that dark matter would have sprung into existence not long after the
earliest period of the cosmos’ formation. A time when it was a fiery soup of elementary
particles, bubbling like a searing pot of liquid, which cooled as the universe expanded.
The particles then grew further apart, with collisions becoming less likely as time wore
on. Dark matter would have been filtered out of the
bubbles of plasma, eventually taking its place in space
and time. Turn to page 14 for the full report.
See you next issue – have a great Christmas!
