I think one of the most common misconceptions about the universe is the distance at which radio waves and other communication media can be detected in space. A 100kw radio station's signal, typical of a century ago, would degrade due to the inverse square law, so it would only be detectable out to one light year. Below the level of about -192dB, signals become indistinguishable from background noise, so our radio bubble is actually far smaller than has been represented by well-known science educators
Just got in from my day and scrolling through my YouTube feed I have several other tabs that I came across that I'm going to watch but you wouldn't believe how fast the newest StarTalk episode automatically got pushed to the front of the queue!
The “empty space” inside an atom isn’t really a vacant room waiting to be filled. It is a strange quantum landscape where matter behaves in ways that are very different from the world we experience every day. Between the tiny nucleus and the regions where electrons are most likely to be found, there appears to be an enormous amount of space. Yet this space is not simply nothing. It is governed by invisible fields, forces, probabilities and energy.
An electron does not move around the nucleus like a miniature planet following a clearly defined orbit. Instead, quantum mechanics describes the electron using a probability distribution—a kind of cloud that tells us where the electron is likely to be detected. The electron can exist in different quantum states, and those states determine the structure and behavior of the atom.
This also helps explain why the electron does not simply fall into the nucleus. There is no tiny physical barrier holding it back. Instead, quantum mechanics places limits on how precisely an electron's position and momentum can be known. Confining an electron to an extremely small region would give it a very large uncertainty in momentum and therefore a much hig
Haven’t listened/watched startalk in a few years, and it’s very noticeable to me how much more knowledgable Chuck Nice has become. Getting in great info and little jabs of wisdom!!! “This guy a regular Einstein over here”!!! Love it ❤❤❤
A cool side show would be Neil showing us all the objects on his shelves, the stories behind them, one short per object, just a few raw vids, no cuts, and take a few months to get them all covered.

😂 you’re right Neil! We don’t HEAR lightning when we SEE thunder. Cheers❤
