New insights on the Hand of God Dave Darling 2025-08-23 | In 2009, NASA’s Chandra X-ray Observatory released a curious image: a pulsar and its surrounding nebula that’s shaped like a hand. Since then, astronomers have used Chandra and other telescopes to continue to observe this object. Now, new radio data from the Australia Telescope Compact Array (ATCA), has been combined with Chandra’s X-ray data to provide a fresh view of this exploded star and its environment, to help understand its peculiar properties and shape.Source: nasa.gov/image-article/x-ray-and-radio-go-hand-in-hand-in-new-imageA paper describing this work, led by Shumeng Zhang of the University of Hong Kong, with co-authors Stephen C.Y. Ng of the University of Hong Kong and Niccolo’ Bucciantini of the Italian National Institute for Astrophysics, has been published in The Astrophysical Journal and is available at iopscience.iop.org/article/10.3847/1538-4357/adf333.

Is dark energy getting weaker? Dave Darling 2025-03-20 | Ever since the Big Bang, 13.8 billion years ago, a battle has been taking place. On the one hand, gravity, acting between all the matter in the universe, has been working to slow down cosmic expansion. On the other, dark energy, which permeates all of space, has been acting in the other direction to make the universe expand faster. For several decades, scientists have widely believed that dark energy must eventually win and doom the universe to eternal expansion. But recent results have challenged this view.

LHS 3154b: the planet thats too big for its star Dave Darling 2023-12-04 | Astronomers have found a planet, called LHS 3154b, that seems to be far too big for the star that it’s going around. The planet in question is at least 13 times as massive as Earth but it orbits a star that weighs 9 times less than the Sun. The discovery seems to fly in the face of current theories of planet formation.My other YouTube channels:The Science Fiction Rock Experience (the music show I produce):youtube.com/@ScienceFictionRockExperienceDiscover Maths (with Juan Medina):youtube.com/@discovermathsScience World (with Emrah Polat):youtube.com/@ScienceWorld1My website:daviddarling.info

Edwin Abbott and Flatland Dave Darling 2023-11-14 | Edwin Abbott was an English theologian, educator, and author, born in London in 1838. After a brilliant career at St. John's College, Cambridge, Abbott obtained a fellowship, was master at King Edward's School, Birmingham and at Clifton College, and from 1865 to 1889 was headmaster of the City of London School. During that time he wrote several theological works, a biography of Francis Bacon, and a standard Shakespearian Grammar. But his best-known work is Flatland: A Romance of Many Dimensions, written pseudonymously by A. Square in 1884.My other YouTube channels:The Science Fiction Rock Experience (the music show I produce):youtube.com/@ScienceFictionRockExperienceDiscover Maths (with Juan Medina):youtube.com/@discovermathsScience World (with Emrah Polat):youtube.com/@ScienceWorld1My website:daviddarling.info
Prime numbers: building blocks of the mathematical universe Dave Darling 2023-11-13 | A prime number is just a natural number that can be divided only by itself and 1, without leaving a remainder. That mightn’t seem like a particularly big deal.

Robert Hutchings Goddard: rocket pioneer Dave Darling 2023-11-13 | Robert Hutchings Goddard was an American physicist and rocket pioneer. Although historians point to Konstantin Tsiolkovsky and Hermann Oberth as being the founders of rocket theory, Goddard, a native of Worcester, Massachusetts, is generally regarded as the father of the practical modern rocket. But it was only after his death that the true value of his work was widely recognised.My other YouTube channels:The Science Fiction Rock Experience (the music show I produce):youtube.com/@ScienceFictionRockExperienceDiscover Maths (with Juan Medina):youtube.com/@discovermathsScience World (with Emrah Polat):youtube.com/@ScienceWorld1My website:daviddarling.info
The mystery at the heart of the double slit experiment Dave Darling 2023-11-12 | By the mid-1920s, it was obvious – from the photoelectric effect, the Compton effect, and in other ways – that when light interacts with matter it does so as if it were made of tiny bullets of energy called photons. The rest of the time it goes about as if it were smeared out in the form of a wave. Apparently, light had an identity crisis, and nowhere was that crisis more evident than in an updated version of an experiment carried out long before quantum theory came on the scene.My other YouTube channels:The Science Fiction Rock Experience (the music show I produce):youtube.com/@ScienceFictionRockExperienceDiscover Maths (with Juan Medina):youtube.com/@discovermathsScience World (with Emrah Polat):youtube.com/@ScienceWorld1My website:daviddarling.info
Leptons Dave Darling 2023-11-11 | Fundamental particles of matter come in two forms: leptons and quarks. A big difference between them is that, unlike quarks, leptons don’t take part in strong interactions. They’re subject to gravity, the weak force, and, if they’re charged, electromagnetism, but they don’t experience the strong force.My other YouTube channels:The Science Fiction Rock Experience (the music show I produce):youtube.com/@ScienceFictionRockExperienceDiscover Maths (with Juan Medina):youtube.com/@discovermathsScience World (with Emrah Polat):youtube.com/@ScienceWorld1My website:daviddarling.info
Red dwarfs and their planets Dave Darling 2023-11-10 | Red dwarfs are the smallest, dimmest, coolest, and most common, type of main-sequence star in the universe. Main sequence means that they’re still making heat and light by fusing hydrogen into helium in their cores. The characteristic properties of red dwarfs stem from their low mass, which ranges from less than a tenth to about a half that of the Sun.My other YouTube channels:The Science Fiction Rock Experience (the music show I produce):youtube.com/@ScienceFictionRockExperienceDiscover Maths (with Juan Medina):youtube.com/@discovermathsScience World (with Emrah Polat):youtube.com/@ScienceWorld1My website:daviddarling.info

Bosons Dave Darling 2023-11-08 | Scientists currently recognise two main types of particles in the universe: bosons and fermions. And the property that distinguishes between them is spin – not spin in the ordinary sense but something that’s analogous to it in quantum mechanics. Bosons have a spin that’s an integer multiple of quantum units of angular momentum: 0, 1, 2, and so on. Fermions have an odd half-integer amount of spin, for example, ½ and 3/2.My other YouTube channels:The Science Fiction Rock Experience (the music show I produce):youtube.com/@ScienceFictionRockExperienceDiscover Maths (with Juan Medina):youtube.com/@discovermathsScience World (with Emrah Polat):youtube.com/@ScienceWorld1My website:daviddarling.info
Quarks: a quick introduction Dave Darling 2023-11-07 | All matter is composed of two types of fundamental particles: quarks and leptons. Quarks are the building blocks of hadrons, the two best-known examples of which are protons and neutrons. Hadrons that are made of 3 quarks, such as protons and neutrons, are known as baryons. Hadrons that are made of 2 quarks – a quark and an antiquark – are called mesons.My other YouTube channels:The Science Fiction Rock Experience (the music show I produce):youtube.com/@ScienceFictionRockExperienceDiscover Maths (with Juan Medina):youtube.com/@discovermathsScience World (with Emrah Polat):youtube.com/@ScienceWorld1My website:daviddarling.info

The X-15 was also a rocket-plane but instead of maxing out at 2½ times the speed of sound, it eventually reached more than Mach 6 and flew so high that for minutes at a stretch, on some missions, it wasn’t an aircraft but a spacecraft plunging through the near-airless void 50 or 60 miles above the ground.My other YouTube channels:The Science Fiction Rock Experience (the music show I produce):youtube.com/@ScienceFictionRockExperienceDiscover Maths (with Juan Medina):youtube.com/@discovermathsScience World (with Emrah Polat):youtube.com/@ScienceWorld1My website:daviddarling.info
Von Neumann probes: Where are they all?

Electromagnetism: one of the fundamental forces in nature Dave Darling 2023-10-19 | Electromagnetism is one of the four fundamental forces in nature. I’ve already made videos on the other three – gravity, the strong force and the weak force, if you’d like to check these out. Electromagnetism is the second strongest of this quartet after the strong force. Two features of it make it unique: it’s the only force that acts between electric charges and it’s the only force that can be both attractive and repulsive.My other YouTube channels:The Science Fiction Rock Experience (the music show I produce):youtube.com/@ScienceFictionRockExperienceDiscover Maths (with Juan Medina):youtube.com/@discovermathsScience World (with Emrah Polat):youtube.com/@ScienceWorld1My website:daviddarling.info
