These podcasts are just the audio from my Youtube videos. If you'd like to see visuals too, visit my channel, Let's Find Out:    An overview of the entire macroscopic, observable universe, from the cosmic microwave background and galactic superclusters to our local star, the sun. Part 2 will concern the microscopic universe: atoms, subatomic particles, electromagnetic/strong/weak/gravitational forces, relativity, and how structures emerge out of the quantum sea of probabilistic energy fluctuations.

The Macroscopic Universe | ASMR

Let's Find Out ASMR is here to help you nod off to something calm and interesting. Science, Philosophy, History, Maths... or personally interesting themes in each episode.

ASMR just means content specifically designed to be relaxing and peaceful. It's something to sleep to or just use to have quietly playing in the background while you work away.

4 Hours of Heavy Rain for Sleep

In 1983, two Japanese scientists, Masaki Morimoto and Hisashi Hirabayashi, pioneers in the field of radioastronomy and the search for extraterrestrial intelligence (SETI), got inebriated as they celebrated the Tanabata star festival. They decided to use a radio telescope at Stanford to send a message to one of the brightest stars in the sky, Altair. In the message was information about our planet, our evolution, the human species, and even a high-spirited sign-off, sending both the English word "TOAST" and the Japanese equivalent, "KANPAI" (乾杯). And I love the playful sentiment. 40 years later, their scientific progeny are listening for a response. Spoiler alert. We haven't heard back... yet. But we also explore the nature of these and other messages to possible intelligent alien life out there listening like we are. We touch upon SETI, the Arecibo message, and a few other attempts at establishing a first contact with an extraterrestrial alien species. Thanks so much for watching. ▸ Want to leave a tip or connect?:

That time we said CHEERS! to aliens in 1983 (and other SETI messages to extraterrestrials) | ASMR

Tonight we explore the strange reality of Einstein's General Theory of Relativity and what it means for 3 dimensional beings born into a 4 dimensional Universe. It predicts our birth from a singularity in an expanding Universe, the contraction of space at the speed of light, and both black holes and the infinite time dilation at their horizon. It's bizarre that space truly compresses and time actually slows down deep inside gravitational wells and near the speed of light. We literally observe supernovae billions of light years away exploding at half their normal speed. So let's find out about the history and basics of relativity.   ▸ Want to leave a tip or connect?:    Video credits: Carrol and Ostlie (textbook I used): https://amzn.to/3QtiABm TNG Simulations https://www.tng-project.org/media/ NASA/STSci/ESA Davis and Lineweaver (2003) https://arxiv.org/abs/astro-ph/0310808 Nolan, C.

The Basics of Relativity: Light Speed, Time Dilation, and the Expanding Universe | ASMR

Tonight we're drawing and explaining a spacetime diagram of the entire universe. The universe is far larger than 14 billion light years, and expanding way faster than the speed of light. Let's find out the true nature of the universe.   ▸ Want to leave a tip or connect?:    See youtube video description for full credits.

(These podcasts are the audio from my Youtube channel videos found here: ) Tonight we're browsing a really cool retro 1969 LIFE magazine I found at a local flea-market thrift store. It's main article is about the LEM (Lunar Module) which was the tiny spacecraft that detached from the Apollo Command Module in lunar orbit and sent Neil Armstrong and Buzz Aldrin descending onto the lunar surface to be the first ever humans to step foot on another world. We also browse the rest of the issue and look at some of the more interesting ads of the late 1960's. Lot's of unique and memorable marketing of clothing, appliances, insurance, and of course, booze and cigarettes. Additional context: This issue was from March 1969, and that Apollo 11 mission didn't happen until July of 1969, so it's fascinating to travel back in time and think about the anticipation of the event just 3 months later.
