The Fabric of Spacetime with Neil deGrasse Tyson - Cosmic Queries
Ғылым және технология
Is it time to rethink string theory? Neil deGrasse Tyson and comedian Chuck Nice explore a mix of questions about the fundamental properties of the universe, particles, the speed of light and more!
Could we someday observe particles without smashing them? We take a question from a particle pacifist as well as discover why clouds stay up. Is everything actually floating? We discuss the mystery of electrons: how small are they really? We explore JWST and ponder the problem of primordial galaxies. What does this discovery change about our understanding of the universe?
Is space an emergent property of the universe and not fundamental? Find out how quantum entanglement may weave the fabric of spacetime and why it may be time to rethink string theory. We discuss time dilation while traveling to Mars, what to do when you have an untestable hypothesis, and how Einstein tested the equivalence principle.
Why are photons always moving at the speed of light? What is time like at the speed of light? Learn about the solar neutrino problem and how neutrinos decay. We also explore the dimensionality of parallel lines and how they can, in fact, intersect. All that and more on a another Grab Bag Cosmic Queries!

What are your thoughts on string theory? Is it still worth trying to prove it, or should we refocus our efforts on other scientific questions?

Consciousness can only be experienced. For example, if you had a tooth pain. Million Scientists with their Test tube(Deduction/induction via empiricism) can tell you there is no evidence of tooth pain. You will reject their scientific method because you are having direct experience of this pain. I have direct experience of existence. All i know with certainty is my experience ("Cogito Ergo Sum"). I know with certainty that this existence can only come from pre-existing Self-Sufficient/Perfect Existence(Allah the most Exalted).You have a direct proof of Allah(one/indivisible/self-sufficient/All-loving/unique) with every waking moment through direct experience of life. Once liberalism is replaced by the law of Quran/Sunnah all of the "strings" will come together in harmony/peace/justice and most importantly mercy.

isn't everything just energy vibrating at at its own specific frequency? Everything must have a specific wave form... which makes that object unique. Sound (frequency) passing through a glass sphere filled with water will create light at the center of the sphere. The ingredients are a perfect sphere, water (waves) and sound. (frequency) achieving light speed could just be a matter of finding the correct frequency... and vibrating in one spot at that specific frequency.

This is one of the best episodes of StarTalk.
Who is here that has realized that Lord Chuck could be taking some lessons/classes in Theoretical physics or experimental physics? Damn, the guy is so sharp nowadays and knowledgeable. Indeed birds that flock together stay together. Kudos Chuck,,,
When I have nothing I still have startalk. It’s a breath of fresh air to see people thinking outside of the boundaries of thought that it feels like we were meant to be trapped in. My brain only feels free during these times. Between thinking about work and my small family this is a light for me and I will be forever great full
Two of the funniest and intelligent men I’ve ever had the pleasure of watching. Keep up the good work.
Thank you gentlemen for another educational and entertaining episode. Chuck, the Cajun chef to whom you refer is probably Justin Wilson. He was indeed on PBS back in the days when dinosaurs walked the earth (I know because I too was there) and was also entertaining and educational in all manner of food.

23:13 bro we need a whole episode on this. And get Chuck a blunt. It’ll be your best video!
Great episode! One thing you could also say about clouds are that they are made up of very small particles of water, each of which is buoyant enough to follow air currents. However, when these collect together they form drops of rain or snowflakes that are ‘heavy’ enough to be affected by gravity and fall. In cumulonimbus clouds, sometimes the updraft of air is so severe that hail that is falling is sent back up to gain size. That’s why you occasionally hear of ‘softball’ sized hail. The forces in thunderstorms are amazing.

Very enjoyable session today Neil snd Chuck. Great stuff!
Chuck's deftly tuned wit always enhances Neal's style of delivery. More evidence for the hypothesis that learning new information seems to be more easily achieved while one is in a good mood.
I love seeing this wholesome, fun, black energy in the context of an educational science video- as well as how you treated each and every question as being just as valid as the next, always entertaining everyone's wonder and curiosity. I laughed a lot and really enjoyed this- you guys rock!

I'm just saying, I love to see it in this context especially when the field is often so dominated by white men with a very serious approach.

An imaginary phenomenon, as a smile tends to light up neurons & minds.
Archimedes gave us a good theory of buoyancy back in 200-and-something BCE, it seems to me. A very clever and productive human, he was. It seems to me we should be teaching the sciences in schools with historic scientific discoveries such as his, partly because we've had over 2,200 years if scientific observations to show some way in which he was wrong, and that's a good sign of a very successful theory :-)
Chuck deserves to live on this program full-time - I don't care if he can't pronounce names more complex than Mark and Chris, his humor fits perfectly.
This episode is amazing! So empty space could be like a field that's powering up everything inside the universe?
Hi Neil love your videos And they help me learn astronomy
Particles have rights!
That information on neutrinos is so cool! Neil always explains things in such an understandable way. 😊
Chuck and Neil are the perfect combo
Every time Neil talks about how quantum entanglement works, it sounds like its just travelling through a fourth dimensional pathway we have yet to learn to observe.
i learned by no mans sky that its actually faster to rise above the atmosphere to travel somewhere than to travel through it. so it would take longer to fly a jet along the surface of the earth than it would if you went some distance into the sky and then back down again. thats what the game taught me at least idk if thats reality :)
Dayum what an excellent episode. Great questions, more of these please
37:06 The guy you were referring too is Justin Wilson. The show was called " Louisiana Cookin' " on PBS. My mother and I loved watching his program back in the day and hearing his stories. I hardly knew what he was saying (other than, "I guarONtee"), but my southern mother understood his every word. 🤣
The whole neutrino oscillation discussion gets me thinking about the whole possibility that the universe keeps pulling a veil over our eyes to hide the truth from us... big galaxies in the early universe, neutrinos that change so we can't measure the original flavor, the inability to localize electrons. I feel like it's all connected to some elaborately woven conspiracy conjured up by the universe itself.

It is wrong. It is "Would have." The pronunciation gets in the way of the meaning. The pronunciation is a contraction: "would've" It is pronounced the same as "would of." That is how we end up with incorrect words. An English teacher these days would probably bury their face in their hands, roll their eyes skyward, and sigh helplessly at the fact that their students refuse to learn any semblance of standard grammar, syntax, spelling, and style.

Humanity's issues not "humanities issues." The nonsense term "humanities" is a woman(aka vague and useless) term similar to amenities in it being a worthless word for " useful items in a place or situation you are in" but more worthless as it is a super vague reference to "the state of affairs" in cultivating all the avenues of curiosity and general experience that is typical in the human existence. Intellectual males are just females in the bodies of men, they adore obnoxious vagueness and inventing useless terns to reflect their fragments~tangents of retardation or "perspective." So called "humanities" is just one such worthless perspective.
Watching these videos have really helped me because i would wonder a lot of these questions but wouldn’t know who or where to go for some explanation. I’m not sure if i can 100% agree upon all these answers but I sure can relate and just keep learning
The lecture series Niel is talking about on the Great Courses is his Inexplicable Universe series. So good I bought the whole series on amazon prime!
This is one of the best science sessions I've ever heard! Funny too!!!!
Neil, I’m glad you live in my iPad and teach me things while I’m at work.

Virtual particles linked by wormholes that weave the fabric of space and time blew my mind. And also the beginning of the universe still existing within the 4th dimension of time, the time arcs on the surface of the balloon. Losing sleep on this gumbo for sure.

this was an awesome episode
i want him to hit 100 million subs so everyone loves and respects astrophysics and science in general
The chef you’re talking about is Justin Wilson. Loved that dude.
so. i think my idea about the double slit experiment is actually correct. when you do the double slit experiment and cause the interference pattern to emerge the photon is actually slowing down through time but in space it becomes unstable and can appear in a random location. it fell beneath the electromagnetic spectrum and all we are left with is evidence the waves which the photon was once surfing on before the experiment "broke down" maybe this is how you explain vaccum energy? idk some random thoughts for ya
out of the bushes for that one. Thanks guys I enjoyed that.
