  • Yeah but this is referencing the movie trope where the person has a fully stopped heart and they shock it back to life. In reality applying cpr is just keeping the blood pumping to supply the brain with oxygen in the hope the body restarts the heart itself. That’s why modern defib machines check the nerve impulses to see if shocking it would help. Of there is no heartbeat, it won’t help and will refuse to shock. Once the body restarts the heart but the rhythm isn’t correct shocking can help. The shocks also aren’t huge shocks where the person violently lurches up and putting in more energy won’t help either. The machine checks the rhythm and applies a series of shocks to help the nerves regain their normal pattern and thus tell the heart to pump in the right sequence and speed. Just randomly zapping will probably do more harm than good.

    It’s pretty nice the emergency defib machines we have all over the place these days are smart enough to help without needing to know how it does their thing. Because 80s and 90s TV and movies have muddied the water quite a bit.

    People call 911 because they are having a medical issue, cops show up and shoot them and their dog, plus the neighbors dog for good measure. Shitheads actually attempt a coup, try to hang congress people, invade government offices, somehow only one of them gets shot. It makes 0 sense.


  • That’s within a solar system, where distance, time lines and energy is relatively low.

    Any event with enough energy for something to leave the solar system, destroys all life, even microscopic. And even if somehow it does survive and leave the solar system, space is pretty much empty so it will probably never hit anything. But if it does hit something, 99% of what’s out there is stars. So it would end up in a star. And if it does hit a planet, coming in at intergalactic speeds absolutely destroys any life. None of that matters though, because the distance involved is so freaking huge, nothing living can survive that long. Travel times are so long, only fossils would arrive, that’s how long we are talking.


  • If aliens were to visit us it’s a miracle not only in space but also in time.

    Space is huge, for some aliens to randomly arrive here would mean they are just about everywhere. We would surely see signs of them in other solar systems, even if they haven’t visited here. There are so many solar systems out there, you don’t just randomly stumble upon ours. And the space in between systems is also so big our brains literally can’t fathom it.

    But time is huge as well. Humans as a civilization with electricity and technology has only existed for 200-300 years (being generous). Some say aliens have only been interested in us since the atom bomb, which is not even 100 years. However humans as a species has existed for over 100,000 years. And intelligent tool users have been around for about 1,000,000 years. If aliens visited anywhere in that time they would have laughed at the silly monkeys and have been on their way. For them to have randomly stumbled upon us just as we are enjoying our few hundred years of modern civilization is one hell of a coincidence.

    Space is mind bogglingly huge, time as well, for both to line up perfectly for aliens to happen upon us is impossible. Even if life is abundant in our galaxy, the separation of time and space pretty much excludes any chance for contact.


  • I’d go one step further. Not only does our current understanding of the universe not include any possibility for FTL, as far as we understand FTL would completely break reality. Science actively excludes FTL as a thing that can exist.

    Wormholes might be an idea, but they aren’t even at the theory level yet. More of a conjecture that fell out of some math, but can’t exist in the real world.


  • Really I’m gonna need a source for that old timey radio claim. Because that sounds like it’s made up and even if it’s not, correlation does not mean causation.

    There is no known mechanism for non ionizing radiation to have ANY effect on the human body or individual cells besides from a warming effect. And even the warming effect is quite small, there are normally a lot of other factors that have a way bigger effect on the temperature. See the Mythbusters episode where they tried to warm a chicken on a radar emitter. The turning of the radar cooled it down more than any warming from the radar did.

    If there is any truth to claims that non ionizing radiation harms humans, physicists would be all over that. That would mean new physics in an area where there hasn’t been any new stuff for a long time now.

    But it turns out we understand it pretty well and see no mechanism for any harm to occur. In that context all of the studies that find no relation are meaningful. If there seems to be no relation and there isn’t a mechanism to do anything, why would anybody think there is anything to find? Turns out it always comes down to FUD, to further some kind of an agenda.



  • A cancer on humanity? That’s a bit dramatic.

    You know you don’t have to have it dancing in rainbow patterns right? You can choose any color you like and even have it be static. I have most of my keys in blue, with the function and numpad in a soft white. This is a relaxing layout for me that helps me focus. But if you hate it so much, simply turn the lights off, that was always an option. Plus I think you are overreacting a bit, there are plenty of good keyboards out there without rgb that don’t cost much.






  • I did the exact same. Google Play Music was actually a good service back in the day. I hated it when they turned it into YouTube Music. I complained about all the broken stuff, so they gave me a home speaker for free and upgraded me to YT Premium for a year. After that year I stuck with YT Premium, since it was less than $2 extra. They also fixed a lot of stuff I complained about. Not everything, but a lot of it. I think YT Music was released a bit before it was ready. Now it still has some issues, but is mostly fine.

    Usually I watch 1 or 2 YouTube videos a day and without Premium I would most definitely not. I opened a YouTube video on a computer I wasn’t signed in the other day and it started with a 2 minute unskipable ad about crypto stuff (an obvious scam). So I closed it real fast, no video is worth sitting through that. Even with Premium I still need SponsorBlock. But with that combination watching videos is actually fun.

    Still listen to YouTube Music all day at work, so that’s a good value for money for me.
