Dark Andromeda?

Astronomers recently discovered a stronger-than-expected glow of gamma rays at the center of the Andromeda galaxy, the nearest major galaxy to the Milky Way. The signal has fueled hopes that scientists are zeroing in on…


Dark matter and another way of hide-and-seek

For decades, particle physics has been the domain of massive colliders that whip particles around at high speeds and smash them into one another while teams of thousands observe the results. These kinds of experiments…


Gray matter tackles dark matter

… The latest attempt to explain away dark matter is a much-discussed proposal by Erik Verlinde, a theoretical physicist at the University of Amsterdam who is known for bold and prescient, if sometimes imperfect, ideas….


Einstein and Planck Extended?

Erik Verlinde published his paper on gravity as an emergent property, not unlike temperature, making the need for dark matter obsolete. It’s tempting to look for this kind of solutions, as it’s never a satisfying…


A dark galaxy

Using the world’s most powerful telescopes, an international team of astronomers has discovered a massive galaxy that consists almost entirely of Dark Matter. Using the W. M. Keck Observatory and the Gemini North telescope –…


Dark matter gone before we’ve seen it?

In the final data sent by the Hitomi spacecraft, a surprisingly large X-ray signal previously seen emanating from the Perseus galaxy cluster did not appear. This casts a shadow over previous speculation that the anomalously…


Does dark matter exist? And how about gravity?

Erik Peter Verlinde (born 21 January 1962) is a Dutch theoretical physicist and string theorist. He is the identical twin brother of physicist Herman Verlinde. The Verlinde formula, which is important in conformal field theory…
