XYZBlZuWa3warvin-ash-the-universe-doesnt-know-which-way-time-flowsArvin Ash | The Universe Doesn't Know Which Way Time FlowsIt's one of the deepest questions in science: What is time, and why does it seem to flow in only one direction? While everyday experience suggests that time moves relentlessly from past to future, modern physics paints a far stranger picture.

j5rwokGEPLUsabine-can-this-device-tell-us-how-time-actually-worksSabine | Can This Device Tell Us How Time Actually Works?In Einstein’s theory of general relativity, the time an object experiences depends on its acceleration. But time in quantum physics works more intuitively – it’s a universal parameter experienced by every object in the same way.
5Qfd6InbZDIscientists-ran-an-experiment-on-time-the-results-dont-add-upScientists Ran an Experiment on Time | The Results Don’t Add UpWe grow up believing that the world "out there" is solid and independent of us. We assume that a tree in the forest has bark and leaves and a specific location, regardless of whether anyone is looking at it.
8xp3Bs6nZ-Ythe-mystery-physicists-call-the-problem-of-timeThe Mystery Physicists Call “The Problem of Time"Time feels obvious, but physics tells a stranger story about its existence: Theoretical physicist Jim Al-Khalili explores why our sense of time may be incredibly misleading, including the idea that past, present, and future might all exist at once.

That’s one of the biggest questions in science. According to a pair of researchers from the Perimeter Institute, the answer to that is: a quasicrystal.
b86Yr0cR0YEphysicists-rethink-time-and-it-solves-several-big-problemsPhysicists Rethink Time and It Solves Several Big ProblemsEinstein’s general relativity predicts singularities, such as those found inside black holes. These are places where spacetime ends and the curvature becomes infinitely large.
6SLyxveaC_Ethe-day-time-was-divided-how-hours-minutes-and-seconds-beganThe Day Time Was Divided | How Hours, Minutes, and Seconds BeganTime feels like a natural part of life, but the way humans divide it into seconds, minutes, and hours is a surprisingly recent invention. For most of human history, time was not measured with clocks but observed through the movement of the sun, stars, and seasons.
OjxZL2T5EFwsabine-hossenfelder-what-is-time-reallySabine Hossenfelder | What is Time, Really?What is time? That question is hard to answer because it’s really asking a bunch of different questions, like “Why does it feel like time passes?”; “What separates now from the future and past?”; “Where does time come from?” and “What do we even mean by time?”

RuSbqFL6VcYsabine-time-ran-slower-in-the-past-physicists-findSabine | Time Ran Slower in the Past, Physicists FindPhysicists from the University of Queensland in Australia have found evidence that time ran slower in the past. In this video I explain how time-dilation is related to redshift, what that means for light from distant galaxies, and what happens to an observer who falls into a black hole.
