How Many Fundamental Constants Does It Take To Define Our Universe? (Synopsis)

“The joy of life consists in the exercise of one’s energies, continual growth, constant change, the enjoyment of every new experience. To stop means simply to die. The eternal mistake of mankind is to set up an attainable ideal.” -Aleister Crowley As we learn more and more about the Universe, we’d like to describe it … Read moreHow Many Fundamental Constants Does It Take To Define Our Universe?

Finding darkness in the light: how Vera Rubin changed the Universe (Synopsis)

“Science progresses best when observations force us to alter our preconceptions.” -Vera Rubin When you look at a galaxy in the night sky, it’s easy to imagine that it’s just a system of masses like our Solar System, except on a larger scale. Instead of a single, central mass, you have many stars responsible for … Read moreFinding darkness in the light: how Vera Rubin changed the Universe (Synopsis)

Could dark matter be powering the EMdrive? (Synopsis)

“…axions are potentially detectable through their weak coupling to electromagnetism…” -Aaron Chou We know, from hundreds of years of experience with the laws of physics, that momentum is strictly conserved, and therefore a reactionless drive is impossible. What’s not impossible is an engine that has a reaction that’s simply invisible, or otherwise undetectable to us. … Read moreCould dark matter be powering the EMdrive? (Synopsis)

Why Are Dark Matter And Modified Gravity In Such Conflict? (Synopsis)

“All we know so far is what doesn’t work.” -Richard Feynman The past month has seen a slew of papers out highlighting the tension between modified gravity and dark matter. Both recognize the same puzzles and problems with the Universe, and both ideas recognize that either one could be valid. In fact, if you look … Read moreWhy Are Dark Matter And Modified Gravity In Such Conflict? (Synopsis)

Why doesn’t dark matter form black holes? (Synopsis)

“All enterprises that are entered into with indiscreet zeal may be pursued with great vigor at first, but are sure to collapse in the end.” -Tacitus Dark matter makes up the overwhelming majority of mass in the Universe. With five times as much of it as there is normal matter, and the fact that it … Read moreWhy doesn’t dark matter form black holes? (Synopsis)

Dark matter rises to its biggest challenge… and succeeds! (Synopsis)

“Faced with the choice between changing one’s mind and proving that there is no need to do so, almost everybody gets busy on the proof.” -J. K. Galbraith Last month, tensions between dark matter simulations and galactic rotation observations reached a new high. Despite all the successes of dark matter on the largest scales — … Read moreDark matter rises to its biggest challenge… and succeeds! (Synopsis)

No Number Of Additional Galaxies Can Prevent The Universe From Needing Dark Matter

“In order for the light to shine so brightly, the darkness must be present.” -Francis Bacon If you had previously thought the Universe contained a certain amount of stuff, like stars, galaxies and matter, then you might think that learning it had ten times as many galaxies might mean it had ten times as much … Read moreNo Number Of Additional Galaxies Can Prevent The Universe From Needing Dark Matter

Dark matter faces its biggest challenge of all (Synopsis)

“Nothing in the standard cosmological model predicts this, and it is almost impossible to imagine how that model could be modified to explain it, without discarding the dark matter hypothesis completely.” -David Merritt Dark matter is a hugely successful theory for explaining a whole slew of observations about the Universe. Just by adding this one ingredient … Read moreDark matter faces its biggest challenge of all (Synopsis)

Dark Matter Proved Real By Colliding Galaxy Clusters (Synopsis)

“It may be that ultimately the search for dark matter will turn out to be the most expensive and largest null result experiment since the Michelson-Morley experiment, which failed to detect the ether.” -John Moffat Dark matter is a puzzle that’s now more than 80 years old: the presence of all the known, observable, detectable … Read moreDark Matter Proved Real By Colliding Galaxy Clusters (Synopsis)

Dark Matter Riches? Why Some Galaxies Have More Than Others (Synopsis)

“Motions of the stars tell you how much matter there is. They don’t care what form the matter is, they just tell you that it’s there.” -Pieter van Dokkum Everything in the Universe was born with the same ratios of dark matter to normal matter: approximately 5-to-1. It shows up in everything from the cosmic … Read moreDark Matter Riches? Why Some Galaxies Have More Than Others (Synopsis)
