Why general relativity would’ve been discovered without Einstein | Sean Carroll

“Consciousness is fundamental. It's a fundamental property of the world that we inhabit, a fundamental property of the universe.” Subscribe to Big Think on YouTube ► https://www.youtube.com/channel/UCvQECJukTDE2i6aCoMnS-Vg?sub_confirmation=1 Up next, Sean Carroll explains why physics is both simple and impossible | Full Interview ► https://www.youtube.com/watch?v=_TBNJyztai0 What does it mean to be conscious, and why does it feel like something to be you? Neuroscientist Anil Seth argues that consciousness isn’t a mysterious spark but a deeply biological process, one that depends on prediction, perception, and the body’s constant negotiation with the world. In this conversation with philosopher Jonny Thomson, he explores how our brains don’t passively observe reality but actively construct it. 0:00 Einstein — underrated? 1:00 The network of genius 1:16 Classical mechanics 1:48 Space and time 2:21 Electromagnetism 2:59 The speed of light 4:20 Spacetime 5:38 Special theory of relativity 6:31 Inverse square law of gravity 7:56 General theory of relativity 9:07 Schwarzschild solution 10:12 Quantum field theory 13:22 Quantum mechanics 16:16 Why physics is a conversation Read the video transcript ► https://ift.tt/iVI10vT ---------------------------------------------------------------------------------- Go Deeper with Big Think: ►Become a Big Think Youtube Member Get exclusive classes and early, ad-free access to new releases without leaving Youtube. https://www.youtube.com/@bigthink/membership/ ►Become a Big Think Web Member Get the entire Big Think Class library, premium print issues, live events, and more. https://ift.tt/KncoRuH ►Subscribe to Big Think on Substack Get all of your favorite Big Think content delivered to your inbox. https://ift.tt/3YLI8ql ---------------------------------------------------------------------------------- About Sean Carroll: Dr. Sean Carroll is Homewood Professor of Natural Philosophy — in effect, a joint appointment between physics and philosophy — at Johns Hopkins University in Baltimore, and fractal faculty at the Santa Fe Institute. Most of his career has been spent doing research on cosmology, field theory, and gravitation, looking at topics such as dark matter and dark energy, modified gravity, topological defects, extra dimensions, and violations of fundamental symmetries. These days, his focus has shifted to more foundational questions, both in quantum mechanics (origin of probability, emergence of space and time) and statistical mechanics (entropy and the arrow of time, emergence and causation, dynamics of complexity), bringing a more philosophical dimension to his work.
