A neutronstar is typically 10-20km in diameter, yet can spin more than 100 times every second. I'm no math wizard, but rotating that fast, would make the speed of their surface pretty wild!
I'm so excited! I'm going to save this for bedtime for maximum effect though. Thank you for all you do for us SEA! There's so many of us who genuinely appreciate your contribution to our lives. 🙂
Reminds me of pink floyd: cirrus minor....bird sounds morphing into something cosmic weird. That tripped the hell out of me listening to it stoned once. ;)
The speed of sound increases as the density of a medium decreases, *but* counterintuitively is fastest in solids over liquids and then gases, where it is slowest. You want to think it has to do with the connectedness and distance of one constituent molecule/atom to its neighbors. Solids are very connected, liquids less so, and gases least. Lower density means a longer distance traveled with each jump to the next particle. So, the speed of sound in xenon < air < helium < bromine < water < ethanol < lead < ice < aerogel.
The work NASA and other institutions are doing in translating these waves into audible frequencies offers a way to perceive space in a way that feels immediate, almost visceral. It’s as if we’re being handed a different kind of “sensory vocabulary” to experience and understand the cosmos. Take “Earth Song” or the Whistler Mode waves, for instance: these aren’t just signals; they’re impressions of phenomena that shape our planet’s interaction with the universe. Sonification gives these signals texture, bringing them closer to how we naturally understand sound while still preserving the alienness of space. What’s especially striking is how this concept of sound in space redefines what we consider to be “silent” or “loud” on a cosmic scale. When we “listen” to space, we’re not just hearing-it’s more like eavesdropping on an endless conversation of forces, energy, and matter. That these recordings, such as gravitational waves detected by LIGO, can be converted into something we can perceive, essentially allows us to reach across the vastness of space and time. It’s a reminder that the universe isn’t indifferent; rather, it’s humming with stories, just waiting to be translated into sounds that our minds and hearts can grasp.
why do I have to be high to listen to @SEA ? I just feel like I get a deeper understanding....and @Astrum, both superb channels. but Sea uses no ambient music in the background....which is theuraputic ✨
You're swapping and changing between Metric and Merry Can Standard Units more. I know, you want to appease our neighbours across the 'pond', but just keep reminding yourself, 'Science is Metric, Science is Metric, Science is Metric' ;)
sound is air pressure fluctuations detected by the ear, while we can convert some signals from space into sound how can there be sound if there is no air pressure in space? if there is nothing around in the forest to detect the falling tree as it vibrates and displaces air, then it doesn't make a sound.
