FLY2 10,108 Posted April 10, 2019 Report Share Posted April 10, 2019 I'll shine my torch out of the bedroom window. Will that help ! Â Actually, it just goes to show how minuscule we really are. 1 Quote Link to post Share on other sites
colly0410 1,181 Posted April 10, 2019 Author Report Share Posted April 10, 2019 Just watched the program, was very interesting. A new horizon has opened up, I wonder what new discoveries await us??? 3 Quote Link to post Share on other sites
PeverilPeril 3,279 Posted April 11, 2019 Report Share Posted April 11, 2019 Fascinating program. The volume of data was truly stunning - millions of gigabytes on a lorry load of hard discs. And the atomic clock that was developed! Accurate to within 1 second over 10 million years!! Mind boggling. Old Albert will still be smiling.... 1 Quote Link to post Share on other sites
Commo 1,292 Posted April 11, 2019 Report Share Posted April 11, 2019 Wonder who will be around to check if that clock is a second slow or fast in ten million years, don't think it will affect me! Quote Link to post Share on other sites
colly0410 1,181 Posted April 12, 2019 Author Report Share Posted April 12, 2019 How will they know if the clock is a second slow? Will it use itself as a reference? I expect they will have made a more accurate clock by then = 1 billionth of a second in 42 trillion years.. Quote Link to post Share on other sites

colly0410 1,181 Posted May 10, 2019 Author Report Share Posted May 10, 2019 In New Scientist that they discovered that anti-matter sub atomic anti-particles have particle/wave duality, so would the wave be an anti-wave? Oh dear, I'll be thinking about that in bed tonight if I can't sleep... Quote Link to post Share on other sites
colly0410 1,181 Posted July 31, 2019 Author Report Share Posted July 31, 2019 In science daily today... 'Einstein's right - for now'... A star orbiting near the massive black hole at the centre of our galaxy is doing exactly as Einstein's general relativity predicts it should. But they're saying general relativity can't be right as it doesn't predict what will happen when the star is gobbled up by the black hole. They're watching the star hoping it gets gobbled soon so they can see what happens, & see if general relativity still fly's, or if it crashes & burns. They have no idea when the star gobbling will take place... Quote Link to post Share on other sites

colly0410 1,181 Posted August 10, 2019 Author Report Share Posted August 10, 2019 I lay in bed thinking last night.... If a black hole can have a quantum superposition, & that superposition means said black hole can be in two places at once, then I speculate that the mass of the each BH would be halved as the mass would be shared out between them. If the mass of each BH is less than the BH forming mass then would the two superposition'd BH's then no longer be BH's? I'm wondering if this phenomena could explain gamma ray bursts or fast radio bursts as they could be superposition pair black holes going "POP." If however the mass isn't halved, or extreme gravitational fields prevents superposition then my hypothesis has turned to dust.... 2 Quote Link to post Share on other sites
Stavertongirl 1,719 Posted August 10, 2019 Report Share Posted August 10, 2019 Getting a bit worried, that last post makes some sense! I tend to lay in bed wondering why I am not asleep yet. 3 1 Quote Link to post Share on other sites

colly0410 1,181 Posted August 11, 2019 Author Report Share Posted August 11, 2019 Schrodingers equations take some working out, lol.... I'm wondering if a black hole is of such infinite smallness that some other sort of physics beyond quantum physics takes over? How we'd ever be able to prove this I have zero idea. I'm trying to get my head round the concept of 'infinite smallness,' you'd think there's a limit to how small something can be, but then when you think about it in a common sense sort of way you can always go a bit smaller.... I sometimes look at my cat Pix & wonder if he thinks about quantum physics & black holes, I wonder??? 1 Quote Link to post Share on other sites
Jill Sparrow 10,304 Posted August 11, 2019 Report Share Posted August 11, 2019 Schroedinger holds no mystery in this household. If there's a box, there's always a cat in it. That's a probability of 1. When I receive a wine delivery, there are usually 2 boxes...one inside the other...containing 12 bottles. Therefore, there will be two boxes each with a cat inside. That is also a probability of 1.  If I decide to push the boat out and order 24 bottles, there will be 4 boxes and herein lies the problem. I only have 3 cats! As a result, one box must be empty. Another probability of 1.  However, if we assume that the cats who have passed on now exist in another dimension,box number 4 may not be empty at all. In fact, there may be several cats in each box, the permutations of which could be considerable.  Cats, by the way, do not concern themselves with such theories. They are well aware that their owners are way down the pecking order when it comes to intelligence. Meeeow!  and as for maths teachers formerly in receipt of far too much remuneration from the Manning School...my only regret is that there was no box large enough for her! 4 2 Quote Link to post Share on other sites

Oztalgian 3,271 Posted August 14, 2019 Report Share Posted August 14, 2019 What about the infinite improbability drive The Hitchhikers Guide to the Galaxy's entry on the drive also states that it was invented "following research into finite improbability, which was often used to break the ice at parties by making all the molecules in the hostess' undergarments leap one foot simultaneously to the left, in accordance with the theory of indeterminacy". It further explains that many respectable physicists wouldn't stand for that sort of thing, "partly because it was a debasement of science, but mostly because they didn't get invited to those sort of parties." 2 Quote Link to post Share on other sites
Brew 5,409 Posted August 14, 2019 Report Share Posted August 14, 2019 Improbability is alive and well and all around us. It is highly improbable that you will win the Lottery. It is also equally improbable your neighbour will win. The lottery is won regularly,  therefore It is probable that someone will win. If we keep looking long enough and eliminate the improbabilites it's probable we will come across the next jackpot winner.... now you can pinch his ticket   1 1 Quote Link to post Share on other sites
colly0410 1,181 Posted August 15, 2019 Author Report Share Posted August 15, 2019 If something is not totally impossible then it can & will happen somewhere sometime in the universe no matter how improbable it is. It's pretty improbable that I'd win an argument with my wife but one day it will happen, probably sometime in the next 42 trillion years...  1 Quote Link to post Share on other sites
colly0410 1,181 Posted October 22, 2019 Author Report Share Posted October 22, 2019 I put on my Facebook page that I was trying to work out how insulated gate bipolar transistors (IGBT's) work, John (Ayupmeducks) replied "don't even go there Steve!" However I did go there: I was told on my army radio operators course that electrons went one way & holes the other in semiconductors. Been reading some advanced stuff & they actually work by almost pure quantum physics using a lot of quantum tunneling & other quantum effects for them to work, seems just about all electronic gubbins run on quantum physics from LED torch's all the way to supercomputers.... Quote Link to post Share on other sites

colly0410 1,181 Posted October 22, 2019 Author Report Share Posted October 22, 2019 Her name was Paula, she lived in Top Valley & worked at the Royal Hunt pub. It didn't end well as a couple of weeks later she was supposed to be working so I went to the Welfare on my own, I coped of with Tracy from Bulwell Hall, Paula's boss told her she could go as not busy, she came to Welfare & caught me with Tracy, there was shouting & fuss & I was dumped in the middle of the dance floor & that was that, lol...
