The Darwin Day Lecture 2017, with Lawrence Krauss | Cosmic Natural Selection

[@godisjust591]

How could some of the scientists permit themselves to make a claim that would necessitate knowledge as extensive as the scheme of the universe, when their knowledge of the total scheme of being is *close* to zero, when confronted with a whole mass of unknowns concerning this very earth and tangible, lifeless matter, let alone the whole universe? Do scientific discoveries and knowledge cause such a scientist to conclude that matter, *unknowing and unperceiving*, is his creator and that of all beings?

[@mephistounderwood4917]

I like this guy. he not only gets his point across, but he's funny, too. A little humor is good. I Used to teach at an adult education school. Humor kept the students engaged and they were able to learn in a more relaxed way. The humorous anecdotes were also relevant, so while laughing, they were learning. It drove the points home at the expense of others (in the comic form of "Never do what this guy did!") The humor relaxed them, kept them engaged and made the classes interesting, not boring. My boss couldn't understand why the humor was an important part of my teaching style, but the results were obvious and spoke for themselves. All was well, right up until he fired me because he thought I was sleeping with his wife (I wasn't and she had already left him and filed for a divorce because he was an a-hole and she was tired of dealing with the jackass). Then, after firing me for a reason that wasn't a legal reason (some irony(?) there,) he tried to file a cease and desist to prevent me from working for a competitor. Tried represent his own corporation, which is a crime (practicing law without a license) which resulted in his lawsuit for damages and the injunction against my having a job, all getting thrown out for failing to appear. He was sentenced for his crime and my counter suit was granted on grounds of no contest. His lawsuit and attempted injunction were both baseless, so no attorney would take the case. I represented myself, because I knew that his filings were baseless and in violation of all relevant laws and statutes. Even if the judge disliked me and liked him, the judge would have no choice but find in my favor, or have it go to the appellate court on grounds of failing to follow the law. But when he arrived on his own, with his brown nosing friend in tow, I knew I had him right I wanted him. I got money from the counter suit for the filing of frivolous lawsuits and harassment, he got no money, jail time and a fine. I guess, in the end, I was a bad employee.......... I only included the last paragraph, because it's funny. Karma can be a bitch! Not that I believe Karma is a real force, anymore than I believe God is real, but Karma can be sort of real when A-holes that are idiots set themselves up for a fall. Those are really the only times karma comes back around. My former boss was one of those people. Former cop, fired for incompetence and misconduct. Went on to become a PI. No one would hire him, because his first client wound up embezzling hundreds of thousands of dollars from the pension funds of a large new car dealership and used my former boss, the ex-cop, as the fall guy. He was an idiot, an a-hole, paranoid, controlling, narcissistic (after all of his obvious failure, he still believed he was better than everyone else at every thing and that he knew more than anyone about anything) and he was incapable of understanding that his failures were his own fault. When he was being taken from the court room for booking, by the bailiff, it was revealed that he was stupid enough to be wearing his sidearm in the court room, like he was still a cop. That earned him even more charges. The whole time he was yelling about how he was going to prove that there was collusion between the judge and I. That I had bribed the judge for this outcome. Didn't matter that everything he did and was trying to do was in violation of the law. By the way, he was also a "Christian." This is the mentality of some of the religious nut jobs. Too stupid to see or understand reality, so in their own minds, reality twists and bends to suit their fantastical ideas of how the world is.This mentality seems to apply to more than just creationism. My ex-boss is a perfect example of how they can be dangerous beyond just false beliefs and trying to destroy education. I think it was his intent to use firearm on me after we left the courtroom. I wound having to seize corporate assets and auction them off at his expense, to get my money. Be cause he "followed a higher law," he felt he didn't need to honor the judgments against him. He wound up losing everything, because his God wasn't as powerful as my god (I don't have one.) LOL I find these experiences funny. I seem to derive great satisfaction when the religious nut jobs find out that their God can't protect them from the consequences of their actions. They may not believe gravity is real, but it will still kill them if they jump off a roof that is 20 floors up. Immoral behavior because it is their divine right victimize those they feel deserve it.

[@vincehusband5570]

Thank you for uploading. Lawrence is as informative and entertaining as ever. Thank you BHA!

[@katiekat4457]

Excellent as always. I love Richard Dawkins and Lawerence Krauss. Always think after a lecture they couldn’t have fulfilled my mind and more and then other lecture comes and again I am a better person inside for hearing it. I love that the audience gave him such a great and long applause at the end. I don’t know if its because they loved it so much (which I’m sure they did) or if its a normal way the british people clap at the end of something. In America our claps are quieter, a little slower, and end much, much sooner even if we loved it. Although we do stand up for things we loved. This is why I love this present time, i am 50yrs old and it was until I was 27 that I got a computer. Young people don’t realize that if you eer had a question about something the only resources you had was your parents who generally didn’t know the answer, wait until you got to school and asked your teacher if you remembered, or wait until the next time you went to the library and look it up in the encyclopedia and hope the answer is there. So you really didn’t expand you brain very much or continue to learn as an adult. If you were especially lucky you might have a set of encyclopedias at you house but generally people didn’t because they were very expensive and the ones you bought because of price weren’t as big as the ones in the library. However let me say that the encyclopedias at the library were pretty big books but there was only about 20, give or take, books to the set in alphabetic order. That’s all there was to generally know to know pretty much everything. That’s terrible right? So my point is, thank you internet but my world has changed since KZbin has grown. All the wonderful lectures, documentaries and everything else the is expanding my mind. I am in awe, every time i say to my self “what is that” or “i want to know more about that” and I don’t have to wait for an answer. I can look it up immediately. Young people have no idea or appreciation for what they have being born when they were. I will look up something in wikipedia and then end up clicking a link on something I don’t understand and before I now it I am 20 pages into where I started. KZbin is the best.

If you're sitting in a spaceship, traveling at 1 meter per second under the speed of light, and you try to throw a ball forward at two meters per second, what happens?

[@GenXersJustWalkItOff]

I am a social scientist, so I've a relatively soft brain, but I'm going to throw this out there so I can learn from responses. Wouldn't we measure it as traveling one meter per second?

[@mvsawyer]

This is the same analogy as the laser beam in the car. Time and distance would be different depending on the observer. For you in the spaceship, you measure the ball moving at 2 m/s because your reference frame is constant. If you shot a laser beam in your spaceship you would measure it going 300,000,000 m/s. But Einstein says that a static observer must also measure your laser beam at 300,000,000 m/s, which they would. So what would the static observer see in respect to the ball, seemingly traveling at superluminal speed? Well, the static observer would see you spaceship's length as extremely contracted so would measure your ball's distance as very very short, and because the observer's second ticks faster than yours, he would also see the ball moving faster than you would. So the static observer would measure your ball moving at a fraction faster than your spaceship but still less than the speed of light. Krauss makes the most intuitive statement about relativity: Spacetime is the fourth dimension, and when it comes to distance, speed, and time, it's like parts of the model you're measuring are rotated into this dimension.

[@sensualarmpit3512]

For you the ball will follow the physics flying at normal speed, external observer would "see" the ball flying very slow. Basicalyy the speed of everythinf in your frame oc reference will be scaled down. Thats basically it.

[@ILuvMoogles]

Badly Drawn Turtle time within an object slows down as the object comes closer to the speed of light, so from your perspective it would look like the ball was moving at 2 meters a second but in reality everything aboard the ship would be slowed to such a degree that it couldn't surpass the speed of light.

[@paulsackery8692]

Badly Drawn Turtle I would think the ball would travel the speed of light plus 1 meter per second because of inertia. But scientists say nothing can travel faster than light.

Im watching so much of LK's stuff that Ive realised that this is more or less similar to his talk two weeks earlier at Seattle Town Hall (LK Why are We Here) but he has a roomier stage to walk about on, I was waiting for him to fall off this one. Bit of a H&S heart stopper and in the UK of all places! but whilst this is for a general audience, I must recommend Lawrence Krauss - The Secret Life of Physicists at NECSS (on YT too)..It is for a more "sciency" audience so gets a tad difficult if you're not from that background but it is great to see him show off his skills and it is damned useful too. Stick with it, let it wash over you and you will forever wish you had not done that arts degree...

[@bobbyb5710]

Why is meassure "weaker" than time?

[@ShalomFreedman]

There is something admirable in the ideal of pursuing the truth even if its revelation is against one's deepest wishes. And what Krauss stresses here is that our scientific picture of the universe does not accord with out deepest aspirations. His mastery of the worlds of astrophysics and particle physics is manifest throughout the talk. He also speaks with a great deal of ironical intelligence and humor. Unfortunately however he is not shy about repeatedly insulting those who disagree with him politically or religiously. His cheap and repeated shots show his very narrow understanding of what religious devotion and observance is all about. His irrelevant political comments are a pandering to the crowd and letting off steam which have no place in a lecture of this kind. But the weight and heart of the presentation are a very learned presentation of current scientific understanding of the development of the cosmos. This is so even though I am not sure it all makes sense to use the Darwinian idea of natural selection as principle here. There is so much not understood in our current understanding of the physical universe that it would have been wiser to focus on dark energy, dark matter, the unification of the four forces as part of their own story rather than fit everything on one principle from a very small albeit special part of the whole story.

[@afriedrich1452]

Smolin's idea is lent a little credence by James Gate's discovery that error correcting codes can be found in the supersymmetric equations associated with string theory. Error correcting 'codes' are found in DNA to prevent too much mutation from happening. Maybe error correcting codes are part of the fabric of the universe to control the mutations during reproduction of universes. You would not need error correcting codes if mutations were not happening at all. Error correcting codes control the rate and manner of mutations - too much and too little mutation is not good. Error correcting codes in DNA are also subject to evolution, meaning that the proper amount of error correction is selected for.

Some may recall the auto manufacturers' resistance to Ralph Nader's recommendations for safety features be built into cars by auto manufacturers, GM specifically complained about it raising the costs to build, etc, but with way more drastic sounding terms. But when insurers discovered how much less was the claims paid out for deaths and other more serious results of injuries in accidents, decades later there's a law to Buckle up, but do you suppose it was for the safety of people or the money made by less claims amounts paid to victims, so the insurers pushed lawmakers to make it almost mandatory to wear them, saving lives, yeah sure. Think back to finally removing lead from gasoline, and then you can read TheNation mag article Worse Than Lead tghat was out a few months ago to do with flame retardants. www.thenation.com/authors/jamie-lincoln-kitman/ But if lead is so bad for people why then do they sell it in 3rd world countries anyway? Sorry, hope I didn't put a damper on one of Dr Krauss great talks.

[@nash984954]

BTW I should mention that lead doesn't break down further, circulates around the atmosphere and they removed it only because it destroyed the catalytic converters that met Clean Air Act regulations, plus continued use of autos meant the pollution caused would be so much worse Listen to the interview of the author of 'Worse Than Lead' it's chilling, this whole story. awfradio.com/tag/worse-than-lead/ AND BIG SURPRISE IT'S ALL ABOUT THE FUCKING MONEY, KILLING US WAS SECONDARY TO THE PROFITS TO BE MADE...BOOM FLAME RETARDANTS ENTER THE PICTURE AND THEY'RE GETTING RICH WHILE WE DIE.

[@Costa_Conn]

The second law of thermodynamics requires that black holes have entropy. If black holes carried no entropy, it would be possible to violate the second law by throwing mass into the black hole. The increase of the entropy of the black hole more than compensates for the decrease of the entropy carried by the object that was swallowed. - Wikipedia (Black hole thermodynamics)

[@The22on]

I'm an engineer. I took 5 years of physics. I must say that I did not grasp a lot of what Krauss said. I suspect it's a combination of me, Krauss, and the difficulty of understanding quantum effects. The difficulty for me started with relativity and quantum mechanics from about 1905 to 1930. The discoveries involved more complex math than ever before. Even Einstein needed his math friend to do the math for him, so I don't feel so bad lol. I suspect I will never fully understand things like physicists do. I am glad we are understanding our universe more and more via experiments and space probes. The world of tomorrow will be interesting. I wish I could peek in at 2200. I suspect it will seem miraculous to me, but because I'm trained in science, I will attribute nothing to the supernatural. I believe that Arthur C. Clarke summed it up best when he wrote: Any sufficiently advanced civilization is indistinguishable from magic. I'd love to see the magic that lies in our future if we don't do something stupid on the way.

Operationally (in the here and now), we kinda understand how things work. Cosmologically (far far away, and billions upon billions year ago) we just don't. It's speculation upon speculation. But that is politically incorrect to say, as a scientist in this age of scientifical marxism.

Thank you for the cave analogy Professor Krauss. I often think about our current state of physics, as a lay person, and think that our most talented and esteemed thinkers have simply gotten stuck down a thought cul-de-sac. I think about three blind men describing an elephant they can touch. Each has a different explanation, but they are really just seeing varying aspects. As you point out, our minds can’t really understand quantum dynamics directly, so we never actually see the real world. I wonder what the real world looks like.

No. Don't open your mind so far that your brain falls out.

Evolution did take place from prototypes both on earth and in the heavens. Saturn and Jupiter were the bosses of the heavens and its evolution, their interactions deciding what stayed and what got kicked out, according to an interesting book I read whose name I don’t recall. There was a pattern or a prototype to evolve to, that is the point missed in this lecture.

42:20 seems so unrealistic, between watching spacecraft travel taking 40,000 years for a distance of 40,000 light years vs oneself travelling through that same distance will take only one week. Almost feels like he is lying but hey nature isn't what u look it to be.

I wonder if the Professor from Gilligan’s Island was replaced with Lawrence Kraus,if they would have made it off the island?

What boggles my brain is..... 1. Maxwell discovers there is a connection between the strength of electric and magnetic forces that dictates the velocity of light. EM force = velocity. So this explicitly demonstrates a connection between "velocity and force". But watch how quickly this point is forgotten by science, its further implications are not respected. 2. Consider that atomic clocks that measure the effect of time dilation associated with General Relativity for example. Time dilation effect is literally defined by an altered frequency of atomic electromagnetic processes. The thing is that an altered frequency can only be accounted for in two ways, altered velocity or altered distance. And science acknowledges neither as being associated with time dilation effect, which is defined by the altered frequency of EM processes. Talk about asleep at the wheel. This is a very simple lead to follow up on. 3. Let us assume the altered frequency of the atomic EM process that clocks demonstrate via GR, is due to an altered velocity. Velocity is related to force right, thats why we celebrate Maxwell's work. So if atomic clocks measure an increased velocity of said EM process, that thats empirically demonstrating an increase in atomic EM forces. 4. And here's the thing......... Atomic forces are equal to the sum of atomic mass. If atomic forces are not constant, then neither is atomic mass. Time dilation effect defines the variable atomic force and therefore also variable atomic mass. You're having a problem with predicting the motions of galaxies right, the rotation velocities for example. You've tried modifying the laws of gravity, and you've tried adding mass in the form of invisible particles that redistributes gravity, but neither quite fits the bill. Try variable mass dependant upon variable atomic forces, for which time dilation effect provides an empirical basis, force = velocity, as described above. Look at the proximity of stars to one another within galaxies, and the less crowded are stars within a given region of a galaxy, then the relative atomic forces, relative atomic mass is increased. Increased time is a measure of increased atomic frequency. Increased frequency caused by increased velocity which equates to increased force "atomic force". Atomic force = atomic mass. You follow me? Atomic force, atomic mass is not constant. Time dilation is literally a measure of velocity change of atomic EM processes, which is a reflection of a variable value of atomic force, atomic mass. All you need to realize to justify this is something you already celebrate Maxwell's work for, that Velocity = force. That's how he calculated the speed of light. You dont have to believe this to try it. and if you try it, you will see it presents a fit for anomalous galaxy rotation velocity, by redistributing gravity within galaxies via a variable atomic mass hypothesis. Relative crowding of stars correlates to anomalous galaxy rotation velocity. Thats what the Tully Fisher relation shows us. See? I'm going to die having convinced nobody to consider this, even though it's justified and simple to check. So it wont be me who history judges poorly
