Universe may end in a “big crunch,” new dark energy data suggests
A Cornell physicist has calculated that the universe may be nearing the halfway point of a total lifespan of about 33 billion years. Using newly released data from major dark…
Dark stars could solve three major mysteries of the early universe
A new study led by Colgate Assistant Professor of Physics and Astronomy Cosmin Ilie, working with Jillian Paulin ’23 of the University of Pennsylvania, Andreea Petric of the Space Telescope…
New research challenges the cold dark matter assumption
Scientists from the University of Minnesota Twin Cities and Université Paris-Saclay are calling into question a long-standing idea about dark matter. Their latest findings suggest that this elusive substance may…
A new theory of gravity could explain cosmic acceleration without dark energy
Why the universe is expanding faster and faster remains one of the biggest open questions in physics. Current theories cannot fully explain this accelerating growth. Today’s standard picture of the…
Scientists find dark chocolate ingredient that slows aging
A natural chemical in dark chocolate may play a role in slowing certain signs of biological aging. Researchers at King’s College London have identified theobromine, a plant compound found in…
Scientists may have found dark matter after 100 years of searching
In the early 1930s, Swiss astronomer Fritz Zwicky noticed that many galaxies were moving far faster than their visible mass should permit. This unusual motion led him to propose that…
We might have just seen the first hints of dark matter
Mysterious radiation from the outer part of the Milky Way could be a sign of dark matter Triff/Shutterstock An unexplained glow that appears to emanate throughout the Milky Way’s outer…
Dark matter acts surprisingly normal in a new cosmic test
Does dark matter behave according to the same physical rules that apply to ordinary matter? This question remains one of the major puzzles in modern cosmology, since this invisible form…
A new equation may explain the Universe without dark matter
For many years, scientists have believed that dark matter and dark energy make up most of the cosmos. But new research challenges that view, suggesting these mysterious components might not…
New quantum network could finally reveal dark matter
Detecting dark matter, the invisible substance thought to keep galaxies intact, remains one of the most enduring mysteries in physics. Although it cannot be directly observed or touched, researchers suspect…
