Dark matter may have started as light-like particles that abruptly became heavy—a cosmic twist rooted in spin and ...
Researchers propose a new theory for the origin of dark matter, the invisible substance thought to give the universe its shape and structure. Their mathematical models show that dark matter could have ...
Physicist Alan Guth, the father of cosmic inflation theory, describes emerging ideas about where our universe comes from, what else is out there, and what caused it to exist in the first place.
such as near black holes or during cosmic events like the collision of neutron stars, the effects of gravity can be significantly different and would require Einstein's theory of general ...
These cosmic strings could stretch the length of the universe. A piece of this string only 1.6 kilometers long would weigh more than the earth. Others have added to the theory: That symmetry still ...
Astronomers thought the Perseus cluster was a massive-but-stable grouping of galaxies, until they found hints of a collision with another cluster — but no one had identified a cosmic interloper ...
It took a full year of testing, experimenting and calculating for them and another group of researchers at Princeton to explain the phenomenon: It was cosmic ... the Big Bang theory, first ...
Cosmic inflation is a faster-than-light expansion ... The first is that Einstein’s general theory of relativity famously makes mass bend space and time – so you’d expect a universe like ...
A study by Dartmouth researchers proposes a new theory about the origin of dark matter, the mysterious and invisible substance thought to give the ...
Dartmouth researchers propose a new theory about dark matter originating from high-energy massless particles colliding in the ...
