Winchester White Posted December 20, 2020 Posted December 20, 2020 Time dilation is a serious head fuck. How do we have such clever people all over the globe that can understand and then push on with amazing science; yet we still fight wars, have poverty and folk called Karen on insta tell everyone vaccines are unsafe and 5G causes the Rona?

I read this short sci fi story called 'Radio Silence' a couple of years ago. It genuinely completely unnerved me and its stayed with me ever since! There's a recording of it here if you fancy listening to it? It's only 6 minutes - but by fuck it's creepy! Quote

If you drop an object in air it will accelerate to a certain speed and then gain no increase in speed once TV is reached. The value of g is independent from separate forces like friction. The resistance from the air puts a force on the object in the opposite direction to g and slows it down. Also have drag. Quote
kent_white Posted December 21, 2020 Posted December 21, 2020 I'm currently up Scout Rd attempting to get a fleeting glance of the great conjunction. Don't bother! 🤬ing British weather! Quote

Don't bother! 🤬ing British weather! Sacked it off a while ago when out with the hounds. Never going to see it, which is a shame as apparently, with binoculars or a telescope, you can see 4 of Jupiter's moons too. Ah well, just another 400 years to wait. Quote

gonzo Posted December 22, 2020 Posted December 22, 2020 Lad downloaded Solar Smash app earlier. Quite therapeutic. No aim to the game just blowing planets to pieces with black holes,laser beams and a host of other stuff. Quote

kent_white Posted December 23, 2020 Posted December 23, 2020 I listen to a YouTube show called Event Horizon. They were talking about this possible radio signal from Proxima Centauri yesterday. They're still betting on it being radio interference from earth at this stage but it's a fascinating discussion - particularly as they outline some of the strange things about the signal. I've never heard them be so credulous about something like this before. What was most interesting was their take on a potential signal from our nearest star. I assumed that this would be looked on suspiciously. Why out of all the trillions of stars would we get a signal from our nearest? Just sounds implausible statistically. Anyway - they explained that the SETI people always assumed that a star close by would be the most likely candidate. The reason being similar to how we communicate on earth. If you call someone on a mobile phone - you don't ring then directly because the power requirements would be ridiculously high. You bounce it off a series of relay stations. They're arguing that an alien civilisation would probably take a similar approach and therefore a signal from a star nearby should be exactly what we're expecting. Anyway - it'll probably still turn out to be birdpoo or someone microwaving a pot noodle on the ISS - but here's the programme if you fancy a listen. Quote
gonzo Posted December 23, 2020 Posted December 23, 2020 Quite mad how the length of signal was the same 40 years ago! Quote
Cheese Posted December 30, 2020 Posted December 30, 2020 This just popped up on my youtube recommendations. He's a bit fucking irritating and nerdy, but this is a great explanation of how they used to re-enter and land the Space Shuttle. Quote
Cheese Posted February 2, 2021 Posted February 2, 2021 Anyone see the SpaceX SN9 launch earlier? The launch was successful, the landing was BOOM. Nearly took out SN10 Quote
Cheese Posted February 18, 2021 Posted February 18, 2021 The Perseverance Rover will be landing on Mars in about an hour... Quote

Tonge moor green jacket Posted February 18, 2021 Posted February 18, 2021 Just came on to see of anyone has put this on. Got it on the box. Fascinating, and curious to see if a big fuck off Martian vehicle appears and swallows up the rover. Quote
Zico Posted February 18, 2021 Posted February 18, 2021 I always find it mad then when you can see that tiny red dot in the sky, millions of miles away, there's this remote control car going around controlled by someone on earth Quote
