How heavy is this element?

What a waste of resources.

Get a proper job

Yay!

Bad cringy jokes, but keep trying eventually you'll get there

32:30 If I poured out my anti-matter onto my table, here in the U.S., it would destroy most of London? What about all the stuff between here and London?

I took this argument a step further in my book, The World Within back in 2018. I argue that the universe is not in fact expanding, but rather feeling the effects of subduction / divergence from other universes either sliding above / underneath ours / crashing into ours, basically overlapping or making contact at the boundary zones. My argument also suggests that all universes are on a sphere, thus giving the impression of expansion in the same way people used to think that the earth’s crust was expanding, when in fact material was just subsiding underneath other continental crusts and thus giving the appearance of expansion. We talk about the corners of our Universe, but in my theory, there are no corners - everything is operating on a sphere, which supports how it can both be flat and curved at the same time. The result of the spherical concept is that, like the separation and reassembly of continental continents every so many million years, I propose that universes act in a similar way.

Oxygen?

I was thinking the most important element was phosphorous, but evidently it's surprise.

You really need to learn more about paleo-American development. Your planetary human time sense is skewed.

…….…and then add on the environment the person grew up in, with maybe emotional or physical abuse or neglect! It’s actually very sad really. It’s such a journey! Great talk, thank you:)

love this

My expectations 🌊

This video is hilarious!🐱

I first saw and heard Dr. Fry in a televison production titled, "Magic Numbers" on the nature and history of mathematics. I was thrilled - especially when she got to quantum mechanics. She is a wonderful, articulate and concise teacher. I find her balanced approach to algorithms and AI comforting. It was heartening to hear Dr. Fry say that the music in the style of Bach was not actually composed music. Programmers are working what what they know about Bach's music. It took the genius of Bach - the person - to create this type of music in the first place. And yet, it can, "...fool a roomful of people." We as the general public are not able to differentiate between content created by advanced AI and the real thing. This has serious implications for societies. Dr. Fry is so right in saying that we need to think about how we use the algorithms and how humans fit into all of this. She is right when she says, "You can't rely on people." One reason you can't rely on people because intelligence is unpredictible. People do not alwyas act in their own best interests. Artificial intelligence will be just as potentially unpredictible. This is a qulaitatively different creation than anything humankind has ever created before. I fear that there are many others who do not share Dr. Fry's balanced viewpoints. Research is roaring ahead from the current levels of AI (which have already been used to cause havoc through spreading misinformation and feeding people inciting content to further keep them engaged online) toward Artificial General Intelligence (AGI) which will be much more powerful and have sentience. There is theoretical potential for later, advanced AGI to be using us instead of us using it. Consider how humanity has treated and used "less intelligent animals" through hisotry. AI will potentially be able to self-replicate, creating mutliple copies, thereby making itself safe from being shut down. It will be able to self-upgrade, self de-bug those upgrades and each time learn how to better self-upgrade the next time. With upgrades, it's architecture will change. Those who created it in the first place may not understand what it has become, making it all the more dangerous. Interfaced with our infrastructures, it will potentially have incredible power and control. It's goals - satisfy what it has been programmed to carry out. And if it perceives people as either unnecessary or worse, a threat to it - what then? What consequences lie in store for us when we have become the "less intelligent animals" from the pont of view of sentient AI? There must be more public education and debate on all of this. I am not optimistic.

Does it matter? Is the diameter of the galaxy used to make the calculation accurate? or is a variable? Are all diameters variables? It would really make a difference if they were.

What is a Jewish Space Laser really?

Even if we forget about thousands of other variations of this experiment with all the timetravel, causality breaking consequences, already the fact that a single atom behaves differently going through a single slit and double slit is enough to blow my mind.

Quantum entanglement does not allow us to actually transmit information from one to the other entangled electron. Looking at one and deducing the state of the other is just that: deducing and following the established rules. The fact that we have no way of telling whether an electron spins up or down until we look at it, is somewhat of a non-event. It follows the randomness of quantums. The decay of the wave function follows our observation. We observe -> we initiate the determination of the state (be that the spin of an electron or the passing of the electron through either slit in the double slit experiment. We should really consider the why much more. And in my book the only logical explanation that fits all the open questions is that we observe the limits of the simulation we live in. Undetermined until the simulation interacts with it. Wave function until we observe the electron passing the slit. superposition until we determine the spin of one entangled electron. The simulation provides the detail when it is required (because observed or interacted with it) and from then on runs with it. We are far too stuck trying to explain the actual physics and math when the "spooky action" is just a result of the restrictions our simulation runs in. The faster we come to grips with that the earlier we can move on and perhaps try and do something worthwhile like try and contact the entity running our simulation.

Interstellar travel by humans is not possible.

nice talk

After what was a great summation of the current state of man's knowledge about black holes, he totally ruined it for me. He just had to do the global warming song dance. He needs all the suckers out there to believe mankind, especially we HORRIBLE AMERICANS are are destroying our Earth with the very gas we exhale - CO2!! I could go on but I won't. He isn't worth the time I spent watching him.

The other end of a blackhole is a multicolored psychedelic hallucination. The other end of a multicolored psychedelic hallucination, is a blackhole, publicly known as “bad trip”.

A Child could do better I wish I could get paid oodles of money for spouting nonsense ,or this is a physicist de railed . The Sun he says produces nuclear fusion by squeezing ...My God I would not trust myself to fly in this man's space craft . Even a good O A level physicist could see the flaws in his argument .. Earlier he says I do not consider a 1000 years to be too long say 15 generations ..This person does not live in the real world, God help us all

ths guy is entirely ignorant f Indian mathematics who r the oldest civilisation...

For many many reasons, real interstellar travel (across our galaxy) is the bastion of robots & AI. we can store DNA, record of the sequencing etc...

Les, this an area close to my heart and glad to see this terrific presentation. If we really want to explore our galaxy we have to think of travel for 10s of 1000s of years.

Two things weren’t mentioned. The effect of our Suns gravity and slowing down at the destination

65 octaves. 65 doublings. Reminds me there are 64 squares on a chessboard and the story of the Indian? man who was asked to name his reward by his king and asked for the amount of rice on the last square if the single grain of rice on the first square was doubled dad square. Well, if an octave was a square and our visible window was a single grain of rice, we'd run out of squares before we ran out of octaves but by then, we'd have enough rice to bury the whole u.k under 1.5 metres of rice..

Dad was supposed to be each and I missed a few commas but I hope it's clear enough to add to what the presenter of this wonderful lecture is saying regarding the enormity of the entire electromagnetic spectrum as compared to the tiny part our eyes reveal.

for a sense of scale along the Melbourne foreshore there is a 1 billion:1 scale model of the solar system. The earth is 1.28cm. 150m away is a 139cm sun. 4.5km away in the other direction is Neptune. Near the sun is a basket ball sized Proxima Centauri, which at this scale should be 40,140km, or in the ballpark of once around the earth ...

Could the sound of the beep do something?

Fallacy after Fallacy. How does he know that the light takes 8 min from the sun to earth? That’s another assumption that never has been proven, but accepted by the scientific community.

No. There just saved everyone an hour.

@peter nagy I don't get it

Go back to bed

That the universe was formless, it’s an assumption, nobody knows, and never will, how it was formed and when. Those who make you believe they know, are bamboozling you.

The electron has mass but no size, so how is it not a black hole?

so people will never use solar sales to go inter stellar cause you cant have huge ship cause the sail size would be astronomical and the odds of dmg are gonna go through the roof use for probs maybe

energy sails can be dmged so you need redundant sails be interesting to see how that would work once dmg occurs im thinking nano bots and robots that can repair while redundant ones are out ?

regarding orion you will never get any govt allow that inside earths atmosphere so again you need to build a facility in orbit to do that and this has better potential except it cant be a govt due to the 60s nuclear weapons space treaty if im not mistaken and entrusting this to corporations doesnt give me much more hope but at least it is doable tech and did you all get to the part why it was canceled...that treaty i just mentioned....

WRONG the lasers that powered up the reaction for fusion were more power then they made to create the reaction what they did do was once that powered up the power that was going in was less then the output they got out but they cant sustain that yet in other words the total in power IN was more then the OUT power so far where the sustained power was less then out for a short period but less then the total power in considering the startup lasers the longer they can sustain it the more likely one day it could be viable a lot of lay people made htis mistake about recent fusion id expect a nasa guy whom specializes in this TO NOT get this fact wrong and make it sound we have succeeded when we have not yet this also means that it cant be on at our current tech any longer then what we did here on earth and will require more in power then out NOT viable for a long 1000 year trip or less

and why miniaturize those big buildings make the space ship in orbit with it and go go go put enough for 1.5 the trip distance of start power/sustaining and have at it you really dont want a fusion launch from inside earths atmosphere EVER

Best video i seen recently on youtube ..excellent work

Excellent talk - thank you!

Yea this dude has no idea whatsoever even about the very simplest parts of quantum physics 🤡🤡🤡🤡

Stars are constantly being born so why would it end?

Yes because in the matrix there are many dimensions

Why did a British Lecturer in a UK lecture spell it sulfur? It's Sulphur in English chemistry.

How are such smart people still mispronouncing Uranus
