WSU: Space, Time, and Einstein with Brian Greene

Everything is motion

I love this video and I love that it has so many views.

The shortening of length as it passes by the observer is analogous to the Doppler effect, except in this case it’s the wavelength of light as opposed to sound.

I understand now your explanation! Thank you

Brian should ask for a refund on his education. 🌼🔥👀

Most physicists are called Brian

We teach our kids to bike with traffic and walk against it...

... Gracie and Johnny don't need to throw grenades at each other, bro.

What is the difference between this and the 12 hour video?

Brilliant presentation 👌thank you Brian

เอาอย่างนี้แล้วกันเอาเรื่องวิชาการเก็บไว้ก่อนมันมีหลักการทำงานง่ายๆอย่างนี้เขาใช้เครื่องยนต์ไอพ่นน้ำมันเชื้อเพลิงสูตรพิเศษสารกึ่งนำไฟฟ้าของเหลวผสมเข้าไปในน้ำมันเชื้อเพลิงทำการติดสตาร์ทเครื่องยนต์ไอพ่นใช้แม่เหล็กเหนี่ยวนำพลังงานย้อนกลับ8

Were atoms form thanks to electromagnetism ?
ChatGPT
Yes, atoms are formed and held together primarily due to electromagnetic forces. Atoms consist of a nucleus made up of positively charged protons and neutrally charged neutrons, surrounded by negatively charged electrons in orbit around the nucleus. Electromagnetic forces are responsible for the attraction between the positively charged protons in the nucleus and the negatively charged electrons, which keeps the electrons in their orbits. This delicate balance of electromagnetic forces allows atoms to exist and form the building blocks of matter.

So these atoms come from electrical distribution is space ?
ChatGPT
Atoms themselves do not come from electrical distribution in space, but rather, they are the fundamental units of matter that make up everything in the universe, including the matter in space. Atoms are created through various processes, including nuclear fusion in stars and supernova explosions. These processes generate the elements that make up atoms.

Electromagnetic forces are indeed at play in space, as they govern the behavior of charged particles, such as electrons and protons, and the interactions between them. These forces are responsible for the formation of atoms, as well as the behavior of matter in space. So, while atoms do not come directly from electrical distribution in space, the electromagnetic forces in space play a crucial role in shaping the behavior and interactions of matter, including atoms.

Thankyou for such a beautiful explanation... Physics is really interesting when presented with such clarity.
🙏

Fact: nothing in the universe knows what time is.

Brean Greene, forget Einstein and stand on your own feet, can you?

why don’t we lunch to objects out of earth’ orbit… set them at rest relative to earth… then separate the two objects apart at 300,000,001 meters, shoot a beam of light from one to the other and measure the result? Rinse and repeat at one meter further apart. Just to eliminate earths movement relative to space/time.

😂😂😂Nope. Not true. His illustration shows that the origin of the light is left behind by the target surface when in reality, both, the too and bottom, are traveling together and maintain the same position

I am ignorant àf 😂🎉

GOAT level science presenter

So.long as it is traveling through the resistance of space

I just want to say thanku for giving me hope to understand this ⚛️

Developing an intuition for this will make you crazy.

Clocks are not self adjusting, no matter how fast or slow a clock travels it will stay at one speed!

Nice !!! there is one problem. Enstine has put a stop to the fact that there can be anything faster than the light. This all is true unless until we have any thing faster than a light.
What is faster than a light.

its not that there is no absolute time..its because the quantum field exists independently of the material world, and is always constant. The speed of light C is the speed that energy propagates in the field.

the hand grenade oh noooo

I cant wrap my brain around why the speed of light is needed in an equation used to find the energy in mass.

LOVE HOW HUMAN INTUITION WAS PLACED INTO A PHYSICAL CONTEXT

The best!

Love you Brian Greene but my watch does not tick a minute a time lol. Rare goof on his part.

One of my fav vids of his though. He's so enigmatic in his delivery.

If motion is relative, i keep wondering how would this work if the person moving with the clock watches the counter so they are not in motion and should match the stationary clock while the person on the ground watching the counter in motion should show less time? Is that a paradox?

Brian may i please talk sometime!? Would be very interesting for a non phd to discuss with this. Example ive been writting aoftware since i was 9. Sometimes great insight comes out of our QA testers or none developers because they are thinking out of the constraints we are use to contemplating in. I woukd die to talk with ya gor like 15 mins on an episode! So many questions since i was a youth that still throw my off from modern relativity theory and some other stuff.

And for the example after where it is stated it didnt even get to tick to k yet. If light is constant the time it takes for up and down should always be the same even if the x axis moves more distance. Do they do this in labs or is it solely a visual thought experiment? I woukd love to see it in real action. Im asking these in seriousness. I have always thought something is off about the light examples.

I feel the moving light clock is not accurate. These people are very good but if you were to replace it with something else besides light it still has same affect. Is time really slowing or just distance increasing only per action? According to that thought experiment the further light has to travel time is based in lights traveling distance? Not sure what the clock example is suppose to show. And these experiments based on clocks in orbit etc, why is it not just affects physically on the mechanics of the clock due to gravity, force etc not actual space bending and so on?

❤ you prof . May the creator be on your side .

wow. the lag of that whiteboard is really... REALLY bad.

OMG. I GET IT . 😂😂😂

Brilliant but Brian sure does luv talking with his hands. Tik tok brought me here🎉🎉🎉🎉

wouldnt it be relative to the local star?

The train shrinking concept. To test this, they shoukd make a tunnel the exact length of a stationary train. Then have the train ho through and according to this theory the train should fit inside the tunnel in a moment correct?

The speed of Gravity = c (LIGO)
The speed of the electric field is c (speed of electricity)

c is not the speed of light, it's the speed of fields.

There is a Luminiferous Aether that is comprised of magnetic particles and the speed of light is actually the speed of the magnetic field which is, of course, c.

Thank you!

I do not think out of all lectures by Brian I have listened to he has eeeeeever muttered the words...
uh, or um.
expecting to hear those words from him is excruciating. Thank you Brian

1905 Einstein had a brain fart.

the light clock is amazing.

was watching seriously until suddenly the hand grenade hahaha

Thank you Brian for giving me hope that maybe I’ll understand this one day. I’ll listen to this another dozen times and get back to you!!

We experience-time relativity everyday. The faster we drive, the shorter the time.
