Dr. Greene, I’m sorry I cannot share this program or you with my friends and family. If I did, it would demystify their idea of me being this knowledgeable phenom of physics. They would then be able to easily learn physics themselves by listening to you and I would have no purpose. Lol, I kid, of course. I share this show with everyone I talk to because you make learning physics so accessible that it is criminal. Thank you so much for all that you and your wife does with WSF.

If we move two entangled particles away from each other in our spacetime, the distance between them of course means nothing in the quantum world. Why wonder about spooky action at a distance, what distance, whose distance?

Also, in the presence of the blackhole even far from its center but inside the event horizon, why we don't measure a difference in the orbital behavior of the moon regarding the rotation around the earth?

The description of the relationship between motion through space vs time was especially interesting! I think I understand now how photons can move through space, and 'do things', despite time not passing for them. Still seems a bit weird though to talk about a situation in which a relationship between time and space changes, when the notion of change seems to then refer to some further notion of time - or what is the change with respect to in this case?

7:00 I dont understand this. Two things move away for each other, accelerating. If there is no third observer, then can one know who is the one accelerate? How do I know that it is me who changed the direction? We just saw that now we are moving toward each other. Feeling the acceleration depends solely on one's mass? Not depending on gravitation? The gravitational field is marked with coordinates? Why do I feel the acceleration and not he? I dont capture the difference, from which one may derive that the motion is not symmetrically relative, rather that one who can be considered the stable center of the system. Can anyone help me with this?

I like your comments and explanation 1:27:00 concerning Entropy as in the Second Law of Thermodynamics because finally there's something resembling sense appearing in popular media and in a social network concerning that subject. It's inspired. I've been stating for years to deaf ears, that the Second Law's Entropy only applies to Closed systems and not Open Systems. Nevertheless, it's only in Closed systems one can observe changes in matter and energy and without it, the universe would never change or would endlessly repeat itself. This means that Entropy means a lot more than just "Order to Disorder". What appears broken or shattered in the Worldview, or Closed system is not in the Cosmic View or Open systems. Nor has it lost its connection to many more things we could hardly imagine yet. The alarming sound of "the broken glass shattering" can be just as well be heard as bells of fanfare announcing it's freedom from a system that has no more control over it and can now either move-on to other things or move-up to greater things. Entropy is the only reference and insurance that the clock moves forward for the entire universe's benefit. Any sadness or inconvenience over some broken dish or machine is only, in the end, philosophical.

A Few Contrarian Thoughts (and a few critical): But first, good advice at 23:28 in that in the world of physics, Grueling comes before Glamor (which goes for being a celebrity, too), and good key observation at 24:28 with 'Contribute'. I would have said (to get philosophical), to keep asking questions and to keep being skeptical, but (on a higher and broader plane), to do so within the overarching guidance that the Philosophy of Broader Survival offers, i.e. to operate within the Problem Solver's Mindset, the Strategies of Broader Survival, the Great Struggle, the Pinwheel of Life, and the Ultimate Value and Goal of Life. So I would say to read, understand, and live by that philosophy, since future life (and artificial intelligence) (and physicists) will be using its broad, overarching, existence-guiding guidance. Also, at 24:57 on broad vs. deep and on learning physics by doing problems and problems (beginning with textbooks), a 'great' physicist (which every kid dreams of becoming) will have done ALL of the problems in the textbook, INCLUDING the difficult ones that a typical school course never gets to (having to go 'broad' rather than 'deep'). 'Great' in physics is 'deep'. This does not mean ignoring 'broad', since broad is where new insights come from (as you put things together from various branches for the first time in human history). So there is your 'great'. Note: if you want to avoid the grueling, then love your work (love overcomes all, as they say). 1. On Curved Spacetime 6:15 First, we have to get away from the 'groove/indentation/valley' mental visualization of curved space. That inadequate visualization comes from the bed sheet depiction, which works mechanically, but spatially it is wrong. It would be more beneficial to visualize curved space it as it is, which involves bodies (such as spheres) acting in all directions at once. Second, time does not bend, since time is an idea, not a physical property. It is a tool that we invented to track change. Sure, the clock's internal operations slow due to speed and gravity, but that is still just 'change' in the physical world. Silly physicists mistake time for a physical property, which misleads everyone else, beginning with science fiction writers writing about 'backwards time travel', which is barking up the wrong tree. You want to go back in change (meaning recreate it, since reversing it would be too destructive). Interesting explanation about objects "falling" at the same speed, that they are actually stationary and the earth moves toward them, but even that model has logical flaws (why isn't the earth stationary too, where nothing would 'fall'?). 2. On Our Universe Being in a Black Hole 11:30 First, If we were in a black hole, logic would have it that the universe would not be expanding, but it would be in the process of being crushed, or at least kept crushed, with no space between galaxies. You could argue that the external universe was expanding, which would include our crushed universe, but then you would have to factor in the speed of our being further crushed as the black hole that we were in draws in more stars and matter (the black hole's internal gravity thereby increasing). Second, let's suppose we were inside of a black hole. Nice model, but the question is, 'Now What?' and the answer is we try to escape in order to join the greater universe out there. Third: try to imagine a functioning universe inside of a black hole (or plastered onto its event horizon), and all physics breaks down. The final litmus test is engineering. You cannot successfully engineer to an erroneous model. 3. On Acceleration and Time Slowing 17:58 Acceleration is the ONLY criteria working on change (in that example, which excludes the effects of the environment such as strong local gravity wells), since acceleration is the same as gravity, and since it happens during changes in speed, and not just the change in direction, as you argued. (changes in speed and direction both involve action and reaction). 4. On String Theory 12:06 First, on "a one-dimensional vibrating filament". You do not realize how silly that notion is, and this is why String Theory is a mathematical dead end as a description of the physical world. Here, it is claimed that a physical object has only one dimension, which is not possible. You need three dimensions, or the object is just an abstract thought which itself doesn't even work. As for more than three dimensions, the only hope there is that the extra dimensions actually describe different parameters of a three-dimensional object. You only have three dimensions for an object, no more, no less. More or less is either fantasy or erroneously applied. Get over it. Second, you did not answer the question (on how a string produces a new particle), you went from how a string 'distinguishes' (which you should never have said) between particles to described how a string 'transforms' into a different particle (both by vibrating at a different frequency). So the answer then is that strings (even if they existed) do not produce new particles.

Imagine pre - bigbang neutra-matter when one Lepton lept on, one particle moving through neutra-matter would deflect/repulse other Leptons while a positive is created by the one Lepton leaving, then all the displaced negative Leptons are attracted to the positives, now created, their inertia doesn't stop when neutrality is reached, therefore an ultra negative is reached, repulsing all negative in the inverse square law neighborhood, starting the big bang that was time dilated, where nanoseconds took eons to evolve.

The purpose of life? To live. To experience as much as you can of this collective hallucination, with just a slightly different perspective than anyone else. To experience things and report back to the rest of Us such that we might also decide whether we also want to do the same.

This is Doug from Philadelpia Pennsylvania. I agree with Einstein that each person, tree, rock, or decaying mouse corpse has their own “time”. The two twin experiment were one stays on earth the other travels at light speed and returns is a classic example. My question is why do physical Process slow down at light speed and at light speed would all physical process stop?

Greetings from Nova Scotia.... tremendously interesting and informative as always Dr. Greene. I was fortunate enough to attend your WSF discussion “Beyond the Higgs” last June with my stepdaughter who aspires to be an astro-physicist, and after seeing you in person, now hopes to study at Columbia University. I can only hope that one day soon you’ll be her professor. Very much enjoying your sessions, and I’m wondering if you might be able to address in an upcoming Daily Equation episode, the proof put forth by Andrew Wiles on Fermat’s Last Theorem, specifically the nature of elliptic curves and modular forms. I still have to original Nova Episode “The Proof”, and I understood the logic of how they pertain to the proof (specifically, if Fermat was wrong, you can produce an elliptic curve that is not modular, but Taniyama-Shimura says that every elliptic curve is modular, therefore Fermat must be right) but I don’t really understand the nature of elliptic curves and modular forms on their own. Thank you again for all of your work here on KZbin, both personally and with the WSF. ~ Aaron Sampson

Coming from Welland, Ontario. Question - why didn't researchers find Higgs at Fermilab. Higgs "found" at 125 GeV range. Tevatron peak energy was well above this. Tevatron collided different particles than LHC, but isn't energy energy? Were the detector limitations?

Dr. Greene, first, thank you so much for your series. I forgot nearly all my higher math by now, so I’m just hanging on to this series, but enjoying it! Since I only remember a quarter of algebra, here is a basic relativity question from that perspective. I am floating freely in space and see two trains hurtling towards each other, one going 335 million mi/hr, the other going 336 million mi/hr. Since nothing else is around to give perspective, am I in my rights to say that one is still and the other is actually going 671 million mi/hr, or faster than the speed of light? Also, why is light the only thing allowed to go that fast, and why is that idea accepted?

I've seen a lot of explanations for the falling apple, that it supposedly is in rest and the rest of matter is accelerating towards the apple... but how do you explain it if 2 apples on the opposite side of the world are falling towards earth? The world can't move in opposite sides at the same time.

Just a quick question or thought in regards to time being warped. Isn’t it that movement slows down because of the strength of gravity? The stronger the gravitational force the slower things happen and so in our minds and the way we look at time, time then slows down. Time is only relevant to movement and the change from that movement even at the quantum level. No change no time? Is that basically it or have I got that wrong? Please forgive me if it’s a stupid question I’m pretty uneducated when it comes to science

Prof BGreene, in the Time-Space domain, with Time being, understandably (spelling?) more Intangible Concept, and thus Space being more Tangible, if we now think of Time as a Command, and think of Space, say, Commanded-To, much as Master Slave in Computer Network, is it possible that Time plays the major role, and Space is less effective?

I have a semi-jovial theory that time is caused by fragile time crystals born in the vacuum of space. Each tick is the time atom disappearing when it hits your atom so you get more in space than in high gravity. But also at high velocity a time crystal "shockwave" builds up, hence time slows down or possibly due to lower pressure like white water. The only way to prove or disprove this is to analyse 100 or so atomic clocks worldwide I heard they are networked. Sometimes one particular atomic clock goes out of sync, so all the others pick him up again. If time anomalies appear many atomic clocks at once across the globe mite register a speed up / slow down?! maybe this could be disturbance in this time aether liquid like space weather, normally is very constant but sometimes turbulent.
