What is Cosmic Dust?

Cosmic dust is the detritus of dying stars, a deceptively esoteric substance which pervades the entirety of the known universe. While dust is often made of simple elements, the effect it has on our telescopes, spectrometers, our very understanding of the universe, is quite potent. Today we'll be discussing cosmic dust's history and how it continues to confound experimental physics. From mirroring nearby stars to scrambling cosmological distances, dust is as formidable to new discoveries as it is essential to our very way of life. Our connection to cosmic dust is described in the immortal words of Carl Sagan: “The cosmos is within us. We are made of star-stuff. We are a way for the universe to know itself.” Join this channel to get access to perks:    / @drbriankeating   📺 Watch my most popular videos:📺 Neil Turok    • Neil Turok Believes Physics Is In Crisis (...   Frank Wilczek    • Nobel Prizewinner Frank Wilczek: Beautiful...   Eric Weinstein vs. Stephen Wolfram    • Stephen Wolfram vs. Eric Weinstein: Mathem...   Sir Roger Penrose:    • Nobel Prize in Physics, Black Holes and Wo...   Noam Chomsky:    • Noam Chomsky: Consciousness, Elon Musk, & ...   Sabine Hossenfelder:    • “I Don’t Care About Your Theory of Everyth...   Avi Loeb:    • UFOs & UAPs: The Situation Has Changed! Av...   Follow me to ask questions of my guests: 🏄‍♂️ Twitter:   / drbriankeating   🔔 Subscribe https://www.youtube.com/DrBrianKeatin... 📝 Join my mailing list; just click here http://briankeating.com/mailing_list ✍️ Detailed Blog posts here: https://briankeating.com/blog.php 🎙️ Listen on audio-only platforms: https://briankeating.com/podcast A production of http://imagination.ucsd.edu/ ~-~~-~~~-~~-~ Please watch: ""I understand Quantum Mechanics after this discovery!"
