Wow, gold isn't all that rare relative to most of its neighbors.
The exaggerated cuteness makes it really hard to watch this video. My brain gets cringe paralysis.
I understand how the polariscope works, I am also a glass artist, however I do not know why the stressed material changes the polarization plane of the light. What is going on in the material to cause this? All I can find is explanations on how the polariscope works but not what is actually going on in the material to change the plane of polarization of the light. Please help! :)
Ok, it's been a year since these comments were written, but nobody has mentioned Rindler Coordinates or Born Rigid Body Motion... ok, so here's the thing about proper acceleration of rigid bodies... the material gets compressed if you push on one side of it. In an inertial reference frame everything is _weightless_ Change in velocity is acceleration, change in linear momentum is force. When a spaceship starts throwing reaction mass out of it's engine, the engine changes velocity relative to the rest of the spaceship... this "acceleration" propgates as a "force" through the metal (or whatever) at the speed of sound in the material. This compression wave is either higher than the elastic electrostatic forces in the material and the spaceship gets crushed into a pancake, or the material pushed itself back apart with *_force_* i.e. acceleration. Stuff inside the spaceship "falls down" towards the engine. The reason why any rigid object is feeling a *force* is because one side of the object is moving at a different velocity relative to the other side, and so the two sides of the object are either moving away from each other or moving towards each other. Inside one spaceship, the engine end, on the left in this diagram in the video, is moving right at a greater velocity than the front end of the rocket (where the string is attached). If this was the only engine accelerating, it would compress the string and then compress the right spaceship, pushing it to the right just like everything else. Everything would reach an equilibrium feeling the same compression force and the "same" time-delayed acceleration... Because proper acceleration is only meaningful between two parts of a material object. It's only "absolute" because it's local to the material itself, not the rest of the universe. If you have two rocket engines, both throwing exhaust out, and changing velocity relative to the exhaust i.e. accelerating. Rather than compression between the two engines, there is a tension force pulling them apart from each other. In this video, the string is the part feeling a streching force... because the two ends of it are moving at different velocities and the left side is slower than the right side. If you have one long spaceship with only one single engine in the middle. It will push on the front of the spaceship and *_pull_* on the back of the spaceship. If the spaceship is made from metal with enough tensile strength, it can change the velocity of the back end to catch up with the engine in the middle. If there's too much acceleration (force) from the engine then the back end of the spaceship will break off, just like as if it was held on by string. I you _don't_ want to break this string in this video, the rear (left side) engine must apply more thrust (force) than the engine of the right side spaceship. So... yes, there's time dilation between the ends of each spaceship, and each other spaceship, and everything in front of the spaceships and behind the spaceships. In fact, very far to the left side of this diagram is an event horizon, beyond which no light will ever reach these spaceships for as long as they are experiencing proper acceleration. This is also how gravity works, but the acceleration isn't the compression forces within the rigid object itself. (It's the inertial coordinate systems.)
I'm two years late but OMG you two are insanely cute!! Practically gravitational!
Didnt reallt hepl, maybe im juat frustrated but you went about two minutes and didnt get to the point and felt like you went away from the poin too much
I always think from these videos: can we consider general relativity an approximation to quantum gravity? I mean, the universe is so huge that you can say that's continuous when reality it isn't
Do you think there’s a remote possiblity that human agency as we perceive it is real or is “free-will” as we experience just an emergent property of complex, yet completely deterministic particle collisions?
This is a really good explanation
Imagine that inexplicably-conscious photon ending up in a black hole, thus becoming massive, thus suddenly experiencing a universe with spacetime out of friggin' nowhere.
I believe in retrocausality even though there is no evidence of it, because I don't think it's perceptible
Life-Desire is the Force or Motor of Life, our Consciousness is 100% Electric. Heat and Freeze, is the Two Legs, that All the Stuff-side 'walk on', Heat and Freeze is the Stuff-side of Eternal Ability-Kernels.
Huh?
You are confusing the world of pure Mathematics with the Real World. As a mathematician I cannot prove my own existence ... not since Descartes' "I think, therfore I am!" ass-ertion was shown to be an artifact of the subject-verb-object structure of Indo-European languages. In the language of the Dineh people, for example, you can have thinking all day witout a thinker in sight. I just consider myself "close enough for engineering" in the real world. It's much like the rational approximation of pi as 355/113 is close enough for buildings and even interstellar Astronomy 😂 !
well, current scientific theory is all made up, by themselves. or came from a black hole energy storage.
I reported your video for animal torture (the squirel...). Next I will do the same thing for all Schrödingers cat videos...
Conservation of energy actually isn’t really a thing…
I prefer the neo-Tychonic model, with the Sun as the centre of the rotating Universe, as it explains retrograde motion, stellar parallax, annual Doppler shift, and linear stellar motion. Not only do the stars and galaxies orbit with, unimaginable tangential speeds, once a day, each has their own slanted helix motion on top of that. The Crazy Helix Universe! It's mathematically consistent with modern astronomy. And, of course, it's a geocentric model that's more heliocentric than the heliocentric model.
why does the most insane possibility also feel like the most reasonable one at the same time
How electro and magnetic is proved ?
Oh that’s kinda lame, they should really add a new star color update
So aliens travelling across space, have another reason why they probably won’t….
I see”, said the blind squirrel… I was wondering wth this title was leading to…but you’re right!
Then would heat death still occur?
THANK YOU! As a programmer, I'm trying to understand tensors; I’m learning the math and computer science of tensors for applications with packages like TensorFlow (used for AI development). Breaking down each definition with visual aids helped me unclutter the confusion between what makes something a 2-rank tensor and how it can still be considered 3-dimensional.
0:30 you literally ruined the video at the start Let me get hype about possible time travel first 😂
In the depths of space, where darkness reigns, A mystery unfolds, where science strains. Dark matter, elusive, veiled from sight, Yet in its presence, stars dance in the night. How do we know it exists, you ask? Through cosmic dances, a celestial task. Observations keen, through galaxies spun, Reveal the grip of dark matter, not undone. For galaxies whirl with speeds untold, Yet visible matter cannot uphold The cosmic ballet, the gravitational dance, Without dark matter's unseen advance. In clusters vast, where galaxies thrive, Dark matter weaves its silent hive. Bending light, shaping space, A ghostly presence we cannot embrace. Through cosmic echoes and faint signals sent, We glean the truth of dark matter's descent. A mystery still, yet we persevere, To unlock the secrets it holds dear. So heed the whispers of the cosmic flow, For dark matter's presence, we now know. In the vast expanse of the universe's glow, Its silent embrace, we come to know.
In the fabric of space where mysteries roam, Entanglement weaves its intricate tome. A phenomenon profound, a cosmic ballet, Where particles dance in a quantum display. Entangled they are, in a quantum embrace, Bound by a bond that time cannot efface. Though separated by vast cosmic spans, They dance in unison, defying our plans. But how does it break the universe, you ask? In its enigma lies a daunting task. For entanglement whispers of connections unseen, A web of existence, where reality's keen. Break one entanglement, and chaos may ensue, A ripple effect, tearing reality askew. For in the quantum realm, where uncertainty reigns, Entanglement holds the key to what remains. It challenges our notions of space and of time, Revealing a truth that's profound and sublime. Entanglement breaks the universe apart, To show us the secrets at its very heart. So ponder this mystery, this cosmic affair, Entanglement's dance, beyond compare. For in its embrace, the universe bends, Revealing the wonders that time transcends.
I really enjoy your "How My Wife Reacts" format. Thank you!
Hi Nick, great video, but one question: are any primary elements created as a result of black hole collisions or quasars?
length contraction and mass increase are not real . Time dilation is real . On earth a moving object heading east undergoes time dilation and it can be verified. The earths time does not vary as the object moves because IT is the governing frame. All the energy of motion is used as displacement and to slow time . This slowed time must be then sped up on impact showing increased inertia . Mass increase is not part of that energy equation
😂surprise🎉
Tachyons are so convenient for great speed and communications across the Milky Way in Science Fiction stories. Stating that they don't exist will just motivate physicists to find them.
You’re the best!
So, having given us a few tasters, when are you going to find the energy to release your first album ?
I have pondered this myself and I'm glad this was a recommended video. I've never come up with a satisfying answer either, but nice try. Off to look at your later video now.
It clears things up for me, the end is not iron!
Pi doesn't exist, why, because I ate it...
Empty Space, Particles and Thought-Power, atoms is particles, it is the Condition/Position, (in the Stuff-Circuit) as defines the nature of the particles, all particles is particles.
If these particles are exact reverse copies of each other it is expected at a specific instant they have opposite signs, but do they still have opposite signs when one particle is measured at a certain interval after the other. Only that would mean they are actually communicating.
❤
OR THE AND WITH HOW SCIENTIDTS WORK❤
Wow...such a cute blast from the past!
It almost seems like stars are born in white hole phase, then evolve into stable suns, before ending their lives in black hole phase.
I love that this man is still making these excellent vidoes.
This video is absolutely terrible. Lol
Reacting Backwards in time leads to a deep mystery. Therefore I Love Quantum Physics, it is scientific Philosophie!
I’m trying to listen while brushing my teeth and the only thing that’s coherent is the “mhm” that female makes 60 a minute 😭
I have a question about photon not being able to experience time or space. If space bends, they bend with it. Meaning they are affected by space. They are also experiencing time, as they are not arriving the moment they are produced, from billions of LY away. So I don't understand how they are not affected by time or space.
I have been searching for this for quite sone time. I love that it is specific and discusses the science in a way that answers all my questions. Many KZread presenters give generic explanations but this is science gold.
