    Do the bottom one first. Then as next step, do the math of singularities with a paper cylinder and a paper cone, falling through curved spacetime. That’ll take a little more time and effort but you might just start blowing their minds a little deeper with the same pencil and paper folded in 3D.


  • “Well I think these strange scientists should stop wasting their time peering over microscopes when there’s more important things to do… you know… things that common folk like us can understand and relate to immediately” - any typical anti-reason anti-science (probably religious) dolt, ignorantly vulnerable to things like cholera because they draw their water from the same river where people piss, shit and litter upstream.









  • Among so many other wonderful things, Roger Penrose contained in a single image the mathematics of infinity in our universe, which then can be folded open mathematically further, to reveal a chain of universes in a multiverse.

    An adaptation or upgrade of the Minkowski 4D space diagram (extremely useful in Einstein Relativity, integrating movement through space and time), it’s now called a Penrose Diagram, no less.

    Look at it for a minute. It is deceptively simple. It took generations of great minds to slowly distill to maximum visual simplicity a mathematical expression that encompasses something as wildly vast as an infinite universe with finite speed of causality/information.




  • The thought of Quark Stars have fascinated me ever since I first read about them, about maybe fifteen years ago, a supernova remnant that is dense enough to overcome neutron degeneracy pressure, not dense enough to become a singularity.

    The Cosmic Microwave Background was emitted when the Universe was around 370,000 years old, the oldest light in the Universe but the way space expands and accelerates, the distance at which the photons we detect now were emitted and when they reach us, is all distorted and crazily stretched. If you want to visualize how light moves as slow as a snail in the grand scheme of things, look no further.

    Neutrinos, as far as we know the closest a particle with mass approaches zero, to the infinitesimal point that it’s thought it doesn’t derive its’ mass from the Higgs Field. Then there’s the as-yet elusive Cosmic Neutrino Background, emitted when the Universe was less than a second old.
