Dark matter may have started as light-like particles that abruptly became heavy—a cosmic twist rooted in spin and ...

A study by Dartmouth researchers proposes a new theory about the origin of dark matter, the mysterious and invisible ...

A new study by researchers at Dartmouth College offers a fresh explanation about the origin of dark matter — the mysterious, ...

Everything we visualize about space, including stars, planets, gases, and even galaxies, make up just a small fraction of the ...

According to the study, published in the journal Physical Review Letters, dark matter could have formed in the earliest moments of the universe after the Big Bang from the interaction between massless ...

If space only contained known particles and radiation ... the key to understanding dark energy. Recently, a bold new candidate for dark energy has been proposed: subatomic-size wormholes.

Researchers have an explanation for how dark matter emerged - beginning with weightless particles and ending with massive ...

Axions, hypothetical subatomic particles that were first proposed by theoretical physicists in the late 1970s, remain among the most promising dark matter candidates. Physics theories suggest that ...

Researchers set a new lower mass limit of 2.2 × 10⁻²¹ eV for ultralight bosonic dark matter using stellar motion data from Leo II.

Dark matter makes up a large portion of the universe, but we've never seen it. Here's what we know, what it might be, and why it could change everything. More than 80% of the universe's matter is ...

A study by Dartmouth researchers proposes a new theory about the origin of dark matter, the mysterious and invisible ...

The study introduces a theoretical particle that would have initiated the transition to dark matter. But scientists already know that the subatomic particles known as electrons can undergo a ...
