This is...possibly my favorite episode, just in the first 10 minutes! Pretty good understanding of time and how we interact with it already, but thinking of it as Dr. Liu outlined just put it in a whole new "light". Truly is the final frontier of understanding our universe if we grasp that dynamic. Absolutely thought provoking in the highest order. And so many other points. I have so many questions to submit!

Great question i think they wouldve already turned on, in the exact moment that you reached 100% the speed of light if you intended on turning them on because; Time slows down when you travel faster and faster but time doesnt exist at 100% the speed of light, so for photons, so if you were going to turn them on they would automatically know and already be on and if you werent they never would be and their is no having them off and then turning them on at the speed of light because the information is exchanged instantaneously just like entangled particles in quantum physics thats my theory.

OMG I've never heard anyone else question how dreams might connect to the universe... For decades I've had the feeling that my dreams are just the actions of the me in some other universe. That I'm seeing them, experiencing them sometimes, via some property of quantum entanglement.

its pretty fun to think about the fact that racecar drivers essentially solve a more complicated version of the brachistochrone problem by learning a new track. also its fun to try to do the problem with angular momentum, like a wheel rolling from one point to another, does it change?

What amazed me about Star Trek years ago and how it came true is the communications, i.e. talk out loud and request things happen Hey Google, or Hey Siri. Thermal thermometers just to name a few. I LOVED all that and I knew that some day these things will come true. Thank you Space Program for these advancements! To me the program moved us forward in MANY ways that most people have NO idea where they came from. Love science & technology. NEVER boring!

Very interesting, mind provocative - and funny! Thanks for this excellent content!

Love the show guys!! I listen every night 🎉. But just curious, could you possible do a show on ghosts/pseudoscience? I trust science, but then there are people who say places are haunted like Alcatraz, old buildings, houses etc: places I would never sleep at. I would really love to hear the science of what these explanations could possibly be. Again, love your guy’s work! Both Chuck and Neil inspire all!

Another good 1 guys! It's also possible that we do see into our future in dreams. Not everything is explainable by our current understandings.

One argument *for* seeing the future, that neither NDT or Charles mentioned, is lack of free will, which has been discussed previously on ST. so if the future is predetermined, then why couldn't the brain foresee that? If anything, it should be more impressive that our brain dreams as randomly as it does and doesn't continuously foresee everything.

One of my favourite books (which was a film too) is Lathe of Heaven by Ursula Le Guin. Where the protagonist has dreams which rewrite the past and therefore reality and his psychiatrist attempts to use it to make the universe better with terrible consequences.

For me is the most amazing thing about dreams, that i see clearly people i have never ever seen i my life for sure

Entertaining and enlightening, great combination

It's fascinating how stars and their light that is going at the speed of light also move around the massive black hole so in that way the light they emit also goes around the center of the Galaxy(the massive black hole)also actually moving the light at those enormous speeds depending the stars location(far or distant to the center). Just fascinating 😅

Great discussion. The perception of time is subjective across the globe. However, in some parts of the world (more Western), there is a monochronic way of seeing/experiencing ‘time’… but in places like Africa and Asia, ‘time’ is seen as a polychronic occurrence of their experiences - while at the same time... ‘time’ moves regardless of our experiences. Hope that makes sense?...

I have had dreams that were so accurate that I knew what another person was going to say before they said it. I have only had this happen twice. It was shocking when it happened and I have never been able to make it happen on my own. That does not seem to be a retroactive modification of my memory.

The best way to put it, is that for instance the magnitude of motion of your car, is equal to the magnitude of motion of a photon of light. Both share the same magnitude of motion. What you still can do to your car though, is change the direction of its ongoing motion within the 4D environment known as space-time. If you are whipping down a highway, and make a sudden turn to the left, your body leans to the right relative to your car, and the opposite occurs if you veer off to the right instead. This is due to sudden change of direction. If you hit the accelerate peddle, your body presses against the back of the seat, and if you hit the brakes, your body leans forward. Here too, this body movement is due to sudden changes of the direction of the motion of the car. Anyhow, if you throw together a simple geometric motion vector and length scalar representation of your cars or spaceships motion within space-time, you can then use it to derive the special relativity(SR) equations, and complete this task in mere minutes, even if you have no physics education at all. They currently do NOT teach this specific geometric method in schools, since updates or minor changes these days that lead to seeing things differently or from a different point of view, often are not accepted for over a 100 years.

The explanation of space time and the fourth dimension makes "going back in time" make sense e.g. traveling from Italy to the US at the end of a vacation.

The realization that a rocket trajectory is just the brachistochrone problem was very cool

Love Chuck keeping it light for us lay people

I used to divide by zero on my Dad's Marchant mechanical calculator because it was fun to watch the gears and number wheels spin until they all reached their limit and stopped. That string of 9s was as close to infinity that the calculator could get.

You can go into your dreams if you train yourself over time. I know because I did the experiment. A physic type guy was on Johnny Carson years ago and explained how to interact with your dreams. The 1st time I was able to enter my dream, I couldn't believe it, but I was there. And I was part of the dream, I knew them, they knew me, we conversed and interacted. I did it a few more times and just kinda forgot about it ever happening. But it did, I could do it now if I prepped myself for a few weeks or days.

We all have a friend like Gary... No matter how scientifically you try to handle their "experiences", all they want to hear is "Yes, you are special." 😁

Welcome 😀

Great discussion 👏

36:25 The brachistochrone problem was posed by Bernouilli in the 17th century. In case anyone wondered.

For the first question, I'm a little bit surprised that this wasn't also framed as the way many people (like me) think of Time Dilation: the flatter your curve in the space dimension (faster speed), the less you can move through the time dimension, therefore you experience less time. The hyperbolic math comes out of the observation that the time dilation effect becomes increasingly extreme at an increasing rate as you approach the speed of light through space. Next, i would disagree that warp drive, such as an Alcubierre or similar, necessarily violates causality. While it's true that you might arrive at your destination before the radio signal, that doesn't imply that you arrived before the signal was sent. In the same way that when we eventually watch Betelgeuse go supernova, we will be observing something that actually occurred ages ago. While the Start Trek universe is full of timey-wimey hijinks, such as tachyons and Q, was drive isn't one of them. The warp bubble creates a pocket of spacetime within which time flows normally and is shunted to another place to be stitched back in. The bubble can move superluminally for the same reason that space itself is allowed to expand faster than light speed. The only piece of Trek tech that i don't see happening is the Heisenberg Compensator that allows the transporter to function without violating the eponymous uncertainty principle. My favorite, though, is the deflector dish. I don't know the details of the tech, but it sounds a lot like some of the ideas about how ancient Egyptians were able to move massive stone blocks that even today's cranes would struggle with.

hey Neill, great show! It really makes you think about the different topics. I've got a question for you, Regarding time. First let's set the playing field: Time, past present future. We asume that time goes in a line from the past through the present and into the future. Take the universe. There is a "now" all across the universe at the same time. We can get a glimps of the universe thanks to light that travels at it's speed through the universe. We are seeing "the past". Here comes the juicy bit. The question: Could the present "now" be the knifes edge that pushes through times probabilitywave. In it creating a seperation between the past and the future. But On just the right seperation of the past and the future. there are sparks akin to electricity sparks between the past and the future seperating the past and the future from the now? Wich would make virtual particles in a vacuum "lend" energy from the future to create the particles that imediately selfdestruct. It can not lend power from to far in the future because the "distance" is to great. What I'm trying to say is that : could there be a difference between spacetime and "time"? Great show thank you!

Amazing video!

A bit on the moving on spacetime at light speed I was surprised you didnt mention. Under this theory time dilation is very easily explained as moving diagonally on the plane (assuming light is on the horizontal). As if, if you move at like 0.5 the speed of light, that is also consuming your "time speed", thus you feel time significantly slower. Same as being near a dark hole, the warping of space is so massive, your using your time speed budget.

Lots of lighting here in Arizona. The higher magnitude strikes form fulgurites. Really powerful strikes can eject globs of molten glass and leave holes over a foot across. This happens in less than a second.

To put it more simply: Everything is moving through spacetime at the speed of light. If you're not moving through space, you're moving through time at the speed of light. And if you're not moving through time, you're moving through space at the speed of light. And everything in between is everything in between.
