Dark or Lumpy…

An artist’s impression of the cosmic web (Volker Springel/Max Planck Institute for Astrophysics/et al) Topics: Astronomy, Astrophysics, Cosmology, Dark Matter, Einstein, Research Q: Why does science seem to always change its mind? A: Because, the enterprise of science is about discovery, and a lot of discoveries happen when you have better instrumentation, apply The ScientificContinue reading “Dark or Lumpy…”

Esse Quam Videri…

Credit: Menno Schaefer/Adobe Starlings flock in a so-called murmuration, a collective behavior of interest in biological physics — one of many subfields that did not always “belong” in physics. Topics: Applied Physics, Cosmology, Einstein, History, Physics, Research, Science “To be rather than to seem.” Translated from the Latin Esse Quam Videri, which also happens toContinue reading “Esse Quam Videri…”

Imaging Infinity…

A new image from the Event Horizon Telescope has revealed powerful magnetic fields spiraling from the edge of a supermassive black hole at the center of the Milky Way, Sagittarius A*. Topics: Astrophysics, Black Holes, Cosmology, Einstein, General Relativity Physicists have been confident since the 1980s that there is a supermassive black hole at theContinue reading “Imaging Infinity…”

In Medias Res…

Image source: Link below Topics: Applied Physics, Astrophysics, Computer Modeling, Einstein, High Energy Physics, Particle Physics, Theoretical Physics In the search for new physics, a new kind of scientist is bridging the gap between theory and experiment. Traditionally, many physicists have divided themselves into two tussling camps: the theorists and the experimentalists. Albert Einstein theorizedContinue reading “In Medias Res…”

Liquid Squeezing…

That isn’t tea, but the paradox still applies: Dispersing gold nanoparticles in an aqueous chlorine solution. (Courtesy: Ai Du) Topics: Aerogels, Einstein, Materials Science, Nanomaterials, Soft Materials If you stir a colloidal solution containing nanoparticles, you might expect the particles to disperse evenly through the liquid. But that’s not what happens. Instead, the particles endContinue reading “Liquid Squeezing…”

Einstein Rings…

Multiple images of a background image created by gravitational lensing can be seen in the system HS 0810+2554. Credit: Hubble Space Telescope / NASA / ESA Topics: Astronomy, Astrophysics, Dark Matter, Einstein, General Relativity Physicists believe most of the matter in the universe is made up of an invisible substance that we only know aboutContinue reading “Einstein Rings…”

Heart of Darkness…

Topics: Astrophysics, Black Holes, Cosmology, Einstein, General Relativity In a triumph of observation and data processing, astronomers at the Event Horizon Telescope have captured the first-ever picture of the supermassive black hole at the center of the Milky Way Galaxy. The black hole is named Sagittarius A* (pronounced “A-star”), and the reveal of its image received anContinue reading “Heart of Darkness…”

Shadow of Infinity…

Topics: Black Holes, Cosmology, Einstein, General Relativity When galaxies collide, the central supermassive black holes that they contain begin to orbit each other. This supermassive black hole binary attracts gas, which flows through the system to form two disk-shaped structures, one around each of the supermassive black holes. The gas in these “minidisks” heats asContinue reading “Shadow of Infinity…”

Rogue Singularity…

Topics: Astrophysics, Black Holes, Cosmology, Einstein, General Relativity Each second, a brand new baby black hole is born somewhere in the cosmos as a massive star collapses under its own weight. But black holes themselves are invisible. Historically, astronomers have only been able to detect these stellar-mass black holes when they are acting on aContinue reading “Rogue Singularity…”

Cosmic Existentialism…

Topics: Astronomy, Astrophysics, Black Holes, Cosmology, Einstein, General Relativity “Small” black holes are estimated to make up 1% of the universe’s matter. Scientists have estimated the number of “small” black holes in the universe. And no surprise: It’s a lot. This number might seem impossible to calculate; after all, spotting black holes is not exactly the simplestContinue reading “Cosmic Existentialism…”
