Merging Neutron Stars Deliver Deathblow To Dark Matter And Dark Energy Alternatives (Synopsis)

“Dark matter is interesting. Basically, the Universe is heavier than it should be. There’s whole swathes of stuff we can’t account for.” -Talulah Riley One of the most puzzling facts about the Universe is that 95% of the energy in it, in the forms of dark matter and dark energy, are completely invisible, and have … Read moreMerging Neutron Stars Deliver Deathblow To Dark Matter And Dark Energy Alternatives (Synopsis)

Why don’t we have artificial gravity in space? (Synopsis)

“Designing a station with artificial gravity would undoubtedly be a daunting task. Space agencies would have to re-examine many reliable technologies under the light of the new forces these tools would have to endure. Space flight would have to take several steps back before moving forward again.” -Andy Weir Ever wonder, in those science fiction … Read moreWhy don’t we have artificial gravity in space? (Synopsis)

Why Neutron Stars, Not Black Holes, Show The Future Of Gravitational Wave Astronomy (Synopsis)

“This is going to have a bigger impact on science and human understanding, in many ways, than the first discovery of gravitational waves. We’re going to be puzzling over the observations we’ve made with gravitational waves and with light for years to come.” -Duncan Brown Detecting black holes and the gravitational wave signals from them … Read moreWhy Neutron Stars, Not Black Holes, Show The Future Of Gravitational Wave Astronomy (Synopsis)

Astronomy’s ‘Rosetta Stone’: Merging Neutron Stars Seen With Both Gravitational Waves And Light (Synopsis)

“It’s becoming clear that in a sense the cosmos provides the only laboratory where sufficiently extreme conditions are ever achieved to test new ideas on particle physics. The energies in the Big Bang were far higher than we can ever achieve on Earth. So by looking at evidence for the Big Bang, and by studying … Read moreAstronomy’s ‘Rosetta Stone’: Merging Neutron Stars Seen With Both Gravitational Waves And Light (Synopsis)

Are Space, Time, And Gravity All Just Illusions? (Synopsis)

“Something is happening here and this is going to have an impact.” -Robert Dijkgraaf, on Verlinde’s work There are many attempts out there to reconcile the quantum field theories that describe the electromagnetic and nuclear forces with general relativity, which describes the gravitational force. Certain questions, about gravitational properties in strong fields and on small … Read moreAre Space, Time, And Gravity All Just Illusions? (Synopsis)

The Nobel Doesn’t Mean Gravitational Wave Astronomy Is Over; It’s Just Getting Good (Synopsis)

“Wormholes are a gravitational phenomena. Or imaginary gravitational phenomena, as the case may be.” -Jonathan Nolan Yes, we detected gravitational waves, directly, for the first time! Just days after Advanced LIGO first turned on, a signal of a 36 solar mass black hole merging with a 29 solar mass black hole gave us our first … Read moreThe Nobel Doesn’t Mean Gravitational Wave Astronomy Is Over; It’s Just Getting Good (Synopsis)

Gravitational Waves Win 2017 Nobel Prize In Physics, The Ultimate Fusion Of Theory And Experiment (Synopsis)

“Well, I walked into Building 20 and looked in at the various little labs. There was a bunch of people doing something that looked to me to be sort of interesting, and since I knew all this electronics, I asked them, “Look, can you use a guy?” And I sold myself off as a technician … Read moreGravitational Waves Win 2017 Nobel Prize In Physics, The Ultimate Fusion Of Theory And Experiment (Synopsis)

Is the inflationary Universe a scientific theory? Not anymore (Synopsis)

“I know of no other scientist, no other theoretical physicist alive who has a clearer focus on whether our theories and ideas are relevant to the real world. And that’s always what he’s after.” -Neil Turok, on Paul Steinhardt The inflationary Universe is one of the most revolutionary new ways of looking at the cosmos … Read moreIs the inflationary Universe a scientific theory? Not anymore (Synopsis)

LIGO-VIRGO Detects The First Three-Detector Gravitational Wave (Synopsis)

“Einstein’s gravitational theory, which is said to be the greatest single achievement of theoretical physics, resulted in beautiful relations connecting gravitational phenomena with the geometry of space; this was an exciting idea.” -Richard Feynman For over a century after the publication of General Relativity, it was uncertain whether gravitational waves were real or not. It … Read moreLIGO-VIRGO Detects The First Three-Detector Gravitational Wave (Synopsis)

5 questions you were too embarrassed to ask about the expanding Universe (Synopsis)

“The more clearly we can focus our attention on the wonders and realities of the universe about us, the less taste we shall have for destruction.” -Rachel Carson The idea that the spatial fabric of the Universe itself is expanding, and that’s what’s behind the observed relationship between redshift and distance has long been controversial, … Read more5 questions you were too embarrassed to ask about the expanding Universe (Synopsis)
