reality is awesome
it looks like our ability with longterm memory and cognition is literally due to a viral infection waaaay long ago that was repurposed

reality is awesome way cool
hacking is ANCIENT
And we know this isn't the only time it has happened. In fact, this seems to be a part of how evolution operates. Life is cooler than we imagine. As always.
How do they pick up these static signals if there is no oxygen for sound to travel?...or is that a myth?A first possible glimpse of the beginning of stars, which means the beginning of the universe as we know and see it. And it may also give some new evidence about dark matter. Lots of work still to be done to confirm these findings, but it is definitely weird, cool SCIENCE! whatever it turns out to be.

Aha, makes sense now...thanks.It's not sound, it radio waves. Sound can't travel in space due to lack of any medium to carry them (BTW, any matter can carry sound, not just air, but their speed and other characteristics change based on the density of the medium) and is also far too slow. Electromagnetic waves like radio travel at the speed of light and a quantum field is their "medium", which exists everywhere.

awesome actual demonstration of some deeply strange aspects of our reality. just with polarized lenses.

Did you read about the new Pterosaur unveiled last week. As tall as a giraffe with wingspan of a Cessna? Yikes
