Tonight we're in the Universe Sandbox, a physics simulator of cosmic phenomena. We start with some tutorials, then progress through terraforming, extinction-level impacts like the dinosaur extinguishing Chicxulub Asteroid, and we find out what life around hyper giant stars a million times the size of the sun would be like. 0:00 Intro to the Universe Sandbox and Ad  4:13 Tutorials: Destroying Earth, Terraforming Mars 31:16 Simulating Chicxulub Impact 1:27:44 UY Scuti solar system (Largest known star) 1:56:04 Light-speed impacts 2:15:23 Twin Hyper Giants 2:34:12 True Positions of the Constellations ▸ Want to leave a tip or connect?:   #intotheam #educational #letsfindout #ASMR #relaxing #space #science

It's not quite the original Sumerian Tablets of Gilgamesh, but this is BY FAR my oldest book yet. Tonight's book was published in 1658 by Dr. Thomas Brown, titled, "Pseudodoxia Epidemica: Or Enquiries into Very many Received Tenets, and Commonly Presumed Truths," also known simply as "Pseudodoxia Epidemica" or "Vulgar Errors." It's a work challenging and refuting the "vulgar" or common errors and superstitions of Brown's age. The work was in the vanguard of work-in-progress scientific journalism during the 17th-century scientific revolution and includes evidence of his adherence to the Baconian method of empirical observation of nature. And as we'll see throughout its pages, frequent examples of Browne's subtle humor can also be found. Browne's three determinants for obtaining truth were the authority of past scholarly works, the act of reason, and empirical experience. Each of these determinants is employed upon subjects ranging from common folklore to the cosmological. Subjects covered in Pseudodoxia Epidemica are arranged in accordance to the time-honoured Renaissance scale of creation; the learned doctor essaying on the nature of error itself (Book 1), continuing with fallacies in the mineral, vegetable (Book 2), and animal (Book 3) kingdoms onto errors concerning Man (Book 4), Art (Book 5), Geography and History (Book 6), and finally Astronomy and the Cosmos (Book 7). Pseudodoxia Epidemica was a valuable source of information which found itself upon the shelves of many homes in seventeenth century England. Being in the vanguard of the scientific writing, it paved the way for much subsequent popular scientific journalism and began a decline in the belief in mythical creatures. 0:00 Unboxing 14:15 Book Reveal 23:20 Table of Contents and Ceremonial Candle Lighting 55:50 Reading ▸ Want to leave a tip or connect?: history #books #letsfindout #ASMR #relaxing #mythology #science  

To birth the solar system, you must first invent the universe. - something Carl Sagan probably would've said. The creation of the solar system is a tale of cosmic evolution that spans billions of years. According to the currently accepted Nebular Hypothesis, approximately 4.6 billion years ago, a vast molecular cloud, possibly 65 light-years across and primarily composed of hydrogen, helium, and traces of heavier elements, floated in the dark depths closer to the center of our then-young Milky Way Galaxy. This enormous nebula, was the cradle of our solar system. A significant event, perhaps a nearby supernova explosion, disturbed the calm of this nebula, causing it to collapse under its own gravity. As it contracted, the nebula began to spin faster and flattened into a rotating disk. At the heart of this collapsing cloud, most of the material clumped together to form a protostar—the nascent Sun. As the protostar continued to accumulate mass, the pressure and temperature at its core increased until nuclear fusion ignited, and it began to shine as a true star. Surrounding the young Sun was a disk of gas and dust, where the remaining material started to gather into smaller clumps, gradually forming larger bodies known as planetesimals. In the hotter, inner regions of this disk, rocky planets began to take shape—Mercury, Venus, Earth, and Mars. Farther out, where it was cooler, the gas giants Jupiter and Saturn, along with the ice giants Uranus and Neptune, started to form. As the Sun continued to shine, it emitted powerful solar winds that swept away the leftover gas and dust, clearing the path for the nascent planets to settle into stable orbits. During this time, smaller celestial bodies like moons, asteroids, and comets also formed, many of them remnants of the early planetesimals. Over millions of years, the solar system gradually stabilized. The planets established relatively steady orbits around the Sun, which had reached a stable phase in its life cycle. This long process, spanning tens of millions of years, culminated in the beautifully ordered solar system we observe today, a testament to the dynamic yet orderly forces of cosmic evolution.   ▸ Music generously provided by: (Please go support their beautiful music)  desert sand feels warm at night https://youtu.be/dxO-DeAEZDM?si=dnRgBqoYfKwitxgc  Zerofuturism https://youtu.be/mPYBnlMafS0?si=m1qgtll8orHlvvFj  ONHVN  ▸ Image/Animation Credits: National Aeronautic and Space Agency NASA, Jet Propulsion Laboratory JPL, European Space Agency ESA, Goddard Space Flight Center GSFC, John Hopkin's Applied Ohysics Laboratory APL, National Science Foundation NSF Michael Y.

Tonight we're thumbing through an astronomy book published before the United States was founded, and before EITHER Uranus or Neptune was discovered.

Tonight is a look across the Universe. We begin with the first ever gravitational lensed galaxy found in the 1980's in the galaxy cluster, Abell 370 to another Hubble Deep Field and the size and characteristics of the Universe at the largest scales. Then we go down to the subatomic and see how light interacts with matter and how all electrons are possibly just one single electron moving back and forth through time and space. (that one is seriously fascinating).  Last we discuss the possibility of life in the universe using the parameters outlined by the Drake equation. This uses probabilities about stars, exoplanets, life, civilizations, and their technologies to estimate how many other intelligent living and extinct civilizations there might be in the Milky Way Galaxy.

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.
