Hilarious Reverse Physics Debate: String Theory vs Loop Quantum Gravity
About | Information | History | Online | Facts | Discovery
What's the correct theory of quantum gravity: string theory or loop quantum gravity? Hear world experts Raphael Bousso and Carlo Rovelli forced to attack their own sides during the 2014 Foundational Questions Institute conference "The Physics of Information" in Puerto Rico. See Raphael Bousso and Carlo Rovelli's conference talks here, https://www.youtube.com/watch?v=kq4_dyuy0cs https://www.youtube.com/watch?v=4Qy5Vdzps3g FQXi.org FQXi's 4th International Conference, "The Physics of Information" January 5-10, 2014 Vieques Island, Puerto Rico The past century in physics seems to lead in a surprising direction: away from physics as a description of objects and their interactions, and towards physics as a description of the evolution of information. Is this the correct way to think about physics and the physical world? What is information? What does the term "information" even mean? What role does information play in quantum gravity, cosmology, thermodynamics, life and consciousness, and what links does it provide between these areas? FQXi's international, interdisciplinary conference on the Physics of Information brings together leading researchers to discuss the significance, meaning, and uses of information in physics.

Wow yo momma has changed

I love this idea. Lol I wanna watch this for every possible debate

how did these goofballs ever get in the Navy, shap up or ship out.

To me, gravitons are a dumb way to think of things. Who says fluctuations in spacetime behave exactly the same as (and hence described by QFT) a particle? It's silly. String theory doesn't even explain why compactification exists. It doesn't even explain why one of the four dimensions is different from the others. (Most theories don't but, ok...)
I think maybe LQG maybe more on the right track but still not correct.
I don't believe string theory is correct. The ideas arise from the theories incompatibility with the classical limit of nature.
With String theory, they're shoving reality up the theory's ass.
With LQG, they're shoving quantization up the theory's ass.

More conferences should have this kind of finale.
-
maybe we should study the smartphone gravitational force this days.. people can't resist even in a public speech. Strooong force.
-
is it just me or are they both against string theory? ^^
-
"It's true by definition." You just can't argue with that. Flawless.
-
Extraordinary!
-
Guys, what does Carlo Rovelli say exactly at 6:24? "Imagine..." what?
-
When brilliant minds screw around!!! Hilarious! :)
-
string theory is only game in town...
-
This is one of the funniest videos I've seen in a long time, relaxes the tension a bit in the argument

Yikes. Leonard didn't age well!
Sheldon's cool now? And funny?
He's worked on his humour. -
I believe we the prominent scientists of the 21st century have marched far away from the reality by following the wrong foot paths of some scientists of the late centuries. The reality must be so simple that even a layman of the field could understand and we are struggling with man made paradoxes.
What is gravity to my mind?
Sir Isaac Newton has explained only the physical parameters of the phenomenon called Gravity. The phenomenon is explained whereas the ‘Mechanism of Gravity’, “how Gravity attracts things” is clearly explained. The scientists of the mediator period after Newton, have made it more complicated making a paradox out of gravity by their philosophic definitions which could never be proven practically or mathematically.
I firmly believe Scientists of the 21st century can solve this paradox unless they really want to conserve it as a paradox leaving for the future generations to solve.
Physical Science Students of logical thinking and open mind should ask the questions;
1. Why Gravity does only attract things and why it doesn't repel?
2. Why do Gravity attract only 'Atomic mass' and why not other masses like photon, electrons, solar wind etc?
Before answering above questions we have to clarify 'what are the three Fundamental Space Matter in this world?'. Solids, Liquids and Gasses must be the sure answer from a student of junior secondary level. But we know that they are the three phases of the same Atomic Mass. Then what matter is electron's, light, heat and solar wind etc? Do not they possess a mass?
Perhaps they are tougher and stronger than ‘Atomic Mass’. How about a lightning stroke? It can break even a rock boulder in to pieces but it don’t respond for gravity at all. That category of matter has to be simply recognized as 'Energy Mass' in the world. Solar wind too belongs to that category because it is made up of weakly charged energy particles emitted from Sun.
Then what is the third category of Matter? It is the 'Space Medium Mass'. The space is densely filled with this invisible static matter and that has a Density and a Pressure too (pl ref ‘Space Dynamics-V1/2009-for mathematical derivations). Let’s summarize the three fundamental space matter thence as;
1. Atomic Mass-(everybody knows it as internal rotary systems)
2. Energy Mass-(line projection of energy particles are so recognized but you don’t identify them when speed is lost)
3. Medium Mass-(densely packed particles of speed lost energy mass).
Now only the Mechanism of Gravity can be explained because the different behavior of ‘Energy Waves’ and ‘Energy Rays’ could not be distinguished until the Space Medium is defined well. Energy rays such as light, heat X-ray etc. don’t need a medium to travel because they are line projection of energy particles like photons. But waves such as, natural sounds, electromagnetic Radio FM or AM sounds, TV, Radar etc need a medium to travel. Natural sound simply needs atmospheric medium to transmit but other electromagnetic waves essentially need the free ‘Space Medium’ to transmit the signal. ‘Pressure’ is the most influential parameter of any medium for efficiency in transmitting of energy waves.
Gravity too is born due to a FM wave of high frequency and of the same speed of light. (pl ref ‘Space Dynamics-V2/2009-for frequency and speed analysis of the gravitational wave)
Put a fly in to calm water and you would observe tiny waves generating round and round. That is how atomic masses produce gravitational wave in the space medium due to vibration. A single atom can be considered as a massive rotary organization in which electrons are orbiting vigorously round the nucleus. Students know any rotary machine in the world make a vibration. You would be astonished if you could hear the sound and vibration of the atoms in your own body.
So an atom vibrates and a bigger collection of atoms makes a bigger vibration to transmit a stronger wave through the space medium. That is how gravitational waves are born but how on earth it can attract another mass?
When the waves strike upon any secondary atom in the field, the rotating electron cloud is a bit pushed more closer to the nucleus from the direction at where the wave strikes from. Thence the balance of Coulomb's electromagnetic force between negatively charged electron cloud and the positively charged nucleus is gone. The force from the side of wave strike becomes bigger because the distance to nucleus in that direction is decreased. The resultant unbalance force makes the atom move gradually towards the gravity source and Sir Isaac Newton has explain rest of the phenomenon explicitly.
The other most important thing that scientists of the modern era have to pay attention is the deviation of gravitational fields when the source is in motion. Dynamic behavior of gravitational fields has not yet even touched up to the 21st century. Only the static gravitation was addressed by the Newtonian Mechanics. But just imagine, Sun is rotating and its gravitational field is not static at all.
‘Theory of Gravity Deviation /2009’ explains how a lateral force component, recognized as ‘Orbital Motive Force’, is induced upon planets in the solar system to make them orbit in the same direction of Sun’s rotation. Precession of planets and all the other related paradoxes can be explained if the Scientists of the century are prepared to accept ‘Gravity Deviation’.(pl ref ‘Precession in Orbital Motion of Planets’/2013)
However ultimately the credit of ‘Gravity’ has to be shared between Newton and Coulomb as well because the Mechanism of a so mysterious magical force could never be explained by us unless the marvelous finding, ‘Electromagnetism’ was introduced to the world.
Besides that “Mass of Matter” could never be explained by any of us unless the ‘Theory of Energy Conservation’ is produced by the great scientist Albert Einstein.

Thx ^^ this made me laugh :-D

This is the best thing i've seen all week.
-
hahaha
-
Cool - on many levels! A dialogue like this shows that there is hope for humanity. I'm always very glad to find people who are open-minded enough to do this - between 'rivals' and even in front of an audience. I would love to see strongly religious people do this, too, with their respective religions! Are there any examples our there?
