Lisa Randall. How Physics Scales the Universe

Quantum theories help us to understand a reality that is hidden from our senses, but which affects our daily lives more than we can imagine. Lisa Randall is one of the most important female scientists of our time, author of seminal works that have contributed to our understanding of the universe (or universes) that we live in, such as "Warped Passages" (2011), "Knocking on Heaven’s Door" (2013) and "Dark Matter and the Dinosaurs" (2016). Lisa Randall is at K19 to explain how physics influences us at different levels and how we conceive the universe.
This lecture took place at Kosmopolis 2019 (CCCB, 24 March 2019).

Why she doesnt speak out about something... From we can learn things?

Welll... she is speaking out... in the video you are commenting on..???

[@mnrvaprjct]

easily one of the most important

Never. There are many other intellectuals

She’s explaining the phenomenon of hierarchy or scaling.

[@master_rajeev]

Interesting

[@GeeBeeMike]

She’s a lovely woman. I wish I could meet her one day. I enjoy listening to her thoughts and ideas.

[@jporterfield]

Certainly moments of brilliance and wonderful explanations but...BUT...this was a massively disorganized presentation. I'd like to hear from here again when she can be concise and cogent.

[@clapdrix72]

Really? What specifically did you find disorganized and/or incoherent? Remember she is speaking in a way that considers her non-native English speaking audience.

[@DonWayneMann]

She is amazing!

she is brilliant but over rated

[@ichangedmyself4362]

@@dougraddi908 NOW we have concord. My actual 2 points were: 1. in the long run, atheism is unfulfilling, and 2. she clearly demonstrates that lack of humanity when she takes cheap shots at the greatest nation on earth that has done more for mankind than any other, spent more money on other nations than any other, etc etc. ETC. How you can, with your obvious intelligence, disagree with either of those points, I cannot understand. To deny America's greatness in fact pulls the very rug out from under her own achievements.

Occasional sparks of brilliant hard work but as a whole this scale thing hovered on the ordinary. I have a feeling she trying to shed some light onto hidden secrets of quantum level but stopped short may be some kinda constraints

내가 몇가지 유튜브영상에서 본 물리학은 보편적인 기준은 분자와 원자이다. 그런대 이상한점은 분자상태에서는 파동이 없고 원자상태에서는 파동이 존재한다. 즉물질로 말할수 있는 분자상태는강력으로 파동이 멈춤상태이다. 우리는 물리학을 크게 3가지로 구분해야한다. 파동이 없는 분자 파동이 있는 원자 파동자체가 존재하지 않는 반물질의 세계 즉 입자는 파동이 가능한 상태이고 반물질은 파동이 불가능한 정도의 작은 상태이거나 파동이 적용대지 않는 상태인것이다. 즉 반물질은 강력이 작동하지 상태이기도 하다. 강력이 작동해야 입자를 구성되기 때문이다. 아인시타인의 시공간의 의미는 파동과 물질의 상태이고 중력의 영향에서 휘어진다는 말은 밀집된다는 말이고 밀집되지 않는 공간은 우주라는 공간이 늘어난다는 뜻이고 이말은 반물질이상의 상태를 가진 무엇인가가 소위 우주라는곳에 가득차 있다라고 추정할수 있고 빛이라는 광자가 속도가 존재하는 이유가된다. 반물질우주라는 공간이 없다면 빛의속도는 무한할것이다. 진공이란 상태는 광자가 갈수있는 반물질의공간이 있다는 의미이고 블랙홀은 이런 반물질의 공간이 빛이 지나갈수 없는 상태로 있는것이다. 즉 강력 핵력 전자기력은 수많은 에너지중에 질량에서만 존재하고 중력은 질량이 없는곳에서도 존재하면서도 중력이 약한이유는 간단히 중력을 만드는 어떤 반물질 상태의 무엇의 힘이 약한거 뿐이고 중력은 반물질 상태의 파동인대 그 파동의힘이 물질상태까지도 작동하는 것이다. 반물질의 세계를 다른차원인지는 잘모르겠다. 블랙홀을 통해서 알아볼수 있을것이다. 즉블랙홀의 중심에서 중력을 만드는 반물질의 무엇인가가있고 이것을 알고자하면 중력의 파동을 이해하는 방법밖에 없을듯하다. 초끈이론으로 우리는 물질세계와 반물질 세계로 구분할수 있으나 블랙홀이나 반물질 우주의 존재로 관찰가능한 상태로서 다른차원은 부정하고 광자가 영향을 미치지 않는 상태가 있고 질량이 존재하지 않는 상태가 존재하고 있다는 사실이다 중력파파동의 주파수가 새로운 물리학의 시작일것이다.

Either google translator is very bad for Korean, or you have very little knowledge about physics. But that is ok. You can always study and get better at it.

[@petervandenengel1208]

The fourth dimension is another time dimension: dark matter only works in either the past- or the future momentum, so the LHC will never spot these by using smaller timespace dimensions or higher energy. You can only theoreticly understand them.

[@ichangedmyself4362]

wrong: hold up a box. You are the fourth, fifth and sixth dimensions. Voila!

[@petervandenengel1208]

No, those are surfaces. The three dimensions are line extensions: up/ down, left/ right and depth: befor and behind. But in a way you are right, three us incorrect, because a point is the first dimension of space, a line the second, a surface the third and space aa a sphere the fourth. Time is not a spacial dimension/ but an action, which requires energy.

[@ichangedmyself4362]

@@petervandenengel1208 Yep, I concur, sir. Time is the measurement of movement in relation to the measurer right then or now or later or in the past....

[@privateerburrows]

Question: Has gravity been confirmed at the subatomic scale? Can you actually measure the weight (NOT measure the mass and calculate weight, but measure weight directly) of a subatomic particle? If subatomic weights are only statistically measurable, it would support the existence of a graviton; if subatomic weights are continuously measurable, on the other hand, it might mean there is no graviton. I'm asking because according to General Relativity, gravity is not a force, but rather a consequence of the deformation of space-time and the fact that we are traveling through space-time even when "at rest". If this theory were correct, the graviton would not be needed.
