We can be grateful for great minds the world over, such as Dr Wadia, that leads us to understanding. A question that plagued most of our minds about gravity... was how could it attract everything regardless of an object's properties?... Magnetism works on certain types of metals but gravity, on the other hand, works on everything in the universe, or so it seems. In explaining gravity, Einstein showed us that space and time are a real thing... with physical properties... and now, string-theory may be an explanation of exactly what those properties are.... Pretty exciting stuff really.
If space-time is granular/fragmented, then there has to be some kind of bond between the grains/fragments to hold it all together. And if those bonds are also granular/fragmented, then there must be more "gluons" to hold those "gluons" together, ad-infinitum. There will come a point when you'll just have to admit that infinity/smoothness exists in there somewhere. Everybody keeps saying that "nothing" cannot produce "something". Therefore, there must be something there to make it "smooth". And don't compare it to pixels on your screen.
What ever is going on in space time is determined by the AREA encompassing it. This area is growing proportionally to the amount of information that goes 'in' to the volume. Therefore there must be some granularity in the makeup of spacetime. This holographic like feature is the weirdest thing ever.
Rule of thumb, if it is a TED presentation Do Watch it, if it is a TEDx presentation scan it, 90% or better of TEDx are long winded with low ROI value of your time.

that displacement explains the basic principle of quantum theory. because you cannot observe it directly, you can measure the displacement (ripples in space-time), you can 'almost' deduce the phenomena
I am a experimental scientist. TED talks, while I Do . I have found that , with any concept, a point of perspective leads to a point of view which then leads to an opinion. All of which hinder any true perception.
He jumps from one topic to another without finishing his first thought. Referencing slides we cannot see is like some drawing a white board session during a conference call.
Or like an off-track professor... I forgot I had youtube autoplaying, thought a class lecture recording was playing, and kept skipping this fuckin' page because I assumed it was a TED talk... I guess he didn't get the Rehearse-Yo'-Speech memo.
if you watch every single ted talk in a particular order. you find out something interesting. By the time ANYONE figures out what this is i will have already written my thesis and book on it. The x-men theory. Happy trails. Peace, love and prosper, Humans, aliens and Entities.
String theory is a location grid formation system that allows you to use forceable speed acelleration communication flying systems its devices travels through the GPS system geometric and geographical systems
Vishal Gore and his video is not very well said. He jumps around, and I already knew everything he was saying and I just started high school. Also, like you said, the topic is not too popular, but it is becoming more popular!
Gravity is the product of energy causing atoms to bond and magnetic is gamma energy to hold cores to spin continually in structural composition with our sun as the order of gravitational force, orbital theory says ordered clearly.
The idea emerged from the extension of the Newtonian gravity theory is that the Newtonian gravity is naturally a gauged quite 496 dimensional E8 x E8 mathematical object in 9 dimensional isotropic flat space superposed to 4 dimensional isotropic flat temporal space leading to (9 + 4) - dimensional supergravity. It means that the gravity makes the job regarding the reduction of dimensions and the creation of supersymmetry. It also means we live in 9 dimensional space superposed to 4 dimensional temporal space. But the space dimensions as well as the time dimensions are equivalent to each other because of the isotropy of the space and the time. The problems related to the Newtonian gravity at the galactic and the extra galactic scales are solved with the extension of the Newtonian gravity. It is then expected from the extension of the Newtonian gravity that the observable universe adheres to a 7 layered Multiverse gathering quite 496 universes of the same mass and the same size as the observable universe.
Right. I just talked with a college girl coming from the Eastern Europe and studying math here. She told me that whatever she is studying here in the college, she knew from the tenth grade in the country she came from...There are very few really good Universities in the USA (like Stanford or Berkeley). Many of them are like...the "Liberty" Baptist University!!! LOL
Reasons i think most (relativity/string theory) scientists don't understand what they are talking about: trust me its accurate calculations...that you won't understand...
By the way, did you know that General and special relativity can be combined through the fifth Dimension? Which every 5 year old could understand and could be Explained with under a minute?
the there is somethin with infinit as carateristic in reality there is a force such have some kind of infinite carateristic. why look like many fisics dont like it.?
He explained the black part but not the hole part. But he didn't avoid the subject as he said he wouldn't talk about the singularity. Because his point was to introduce the event horizon to make his later point, not to talk specifically about black holes.
He did talk of information loss, but what about the holographic nature of the black hole. It has no relation with the granular structure of space-time, but seems to be related to strings. Nice video.
That has nothing to do with string theory actually. He didn't even talk about what a string is at first to introduce the branes.. a brane is a 2 or 3 dimension of a string
I'm at minute 15 of an 18 minute talk about strings, and he still hasn't gotten to strings yet... Hey, history is fun and all, but shouldn't you get to your topic?
+Just Another Atheist The point made is that there is no force of gravity but a big ball such as sun kept in the center of a trampoline that creates a depth in the space-time fabric around which the planets revolve and rotate.
Just Another Atheist For that you have to cover the whole setup within the warp i.e, there is no escape for the object but to go near the center. The thing here is the rotation of the objects around a greater mass will ultimately make them to collide but it will take a lot of time. I think since big bang is possibly true considering expansion of the universe as we see. The death of the universe would be the collision of everything at the center of a greater mass since there is no escape.
Mighty Zeus Big bang theory says universe will expand infinitely and die in big freeze.. Since there is nothing outside universe and that nothing is infinite, universe will expand infinitely..
Just Another Atheist You yourself just said that nothing is infinite then how will universe expand infinitely? (maybe u meant nothing is finite). You should check out string theory though it predicts using mathematical equations that there are multiple universes. It has an equation for wormholes and black holes too which possibly has the best use for connecting multi universes and dimensions. So, you can't say that there is nothing beyond our universe. The thing is atom is not the smallest element anymore and our universe is not the biggest thing out there.
There are problems with our current (public) understanding of gravity, issues that bring into question the accuracy of GR. At Lockheed-Martin, they repeated Galileo's experiment with one difference. They took two rare earth magnets and bolted them together with north poles facing each other and placed the bolted magnets together in one box. They dropped it and an identical box at the same time. The one with the magnets in it landed AFTER the other box did. It suggests gravity and electromagnetism are connected. Which implies gravity is not curved space time. This was Tesla's contention, that space has no properties. Two entangled particles affect each other instantaneously - contrary to what this worshipper of Einstein states. Newton's laws and both SR and GR have problems. The Electric Universe model is a better way of explaining how the universe works. And if you use Maxwell's original equations, written in quaternions, rather than Heaviside's rewriting of them in Vector Calculus, you restore the Scalar component of light and will see that faster than light power and information transmission is indeed possible, contradicting a fundamental tenet of Special Relativity. Had we continued down the path Tesla followed we would have antigravity craft and travel to nearby stars. There is an indication that we have Top Secret projects at places like Skunkworks that use this alternate physics. Former head of Skunkworks, Ben Rich, said that we now have the technology to take ET home. He also said anything you saw on Star Trek we can already do. Both statements imply faster than light travel. Sorry Dr. Wadia.
Jeffrey Stewart the problem with your point is that the universe isn’t “electric” because QFT is a proven theory and that implies that maxwells understanding of electromagnetism as waves is incorrect. We have also proven that empty space does in fact have properties. For example, if you have a complete vacuum (0 particles/m^3), virtual particles will come in and out of existence, this is because space itself is a thing, it has energy. Also, we know space time curves because we can prove it. For example, your gps on your phone will never be able to work accurately without accounting for the curvature of the space time around the earth.
Jeffrey Stewart however, we also know that general relativity is not the correct picture because it is incompatible with qft for (maybe) obvious reasons. That is one of the main incentives in the search of the theory of quantum gravity. The universe is broken up into ‘bits’ which is in fact quite amazing!
"The one with the magnets in it landed AFTER the other box did. It suggests gravity and electromagnetism are connected. Which implies gravity is not curved space time. " No, it does not imply that at all. It implies that what you think curvature is, is not what it is. I suspect you learned your Relativity from cartoons, with "curves" signifying "curvature". It is not reasonable to expect that if you add electromagnetic forces into the picture that these electromagnetic forces will act as forces in addition to gravitational forces. Duh. "Had we continued down the path Tesla followed we would have antigravity craft and travel to nearby stars" Nutcase.
A story is not an account and a statement of gravity is not a stretch, thanks genius. I beg to disagree, step out of a thirty story office building and understand gravity immediately captain complicated.
Simultniouty does occurs in the quantum world. This fellow is simply saying what has already been said.. no new ground has been broken... I stopped watching.
String theory has to be closed as soon as possible forever. It is really a shame for scientists to develop this abstract conglomeration of non-understandable formulas...
Now I have made a pledge. I will never again watch a video not made by a native English speaker. Non English speakers, with those from India topping the list, don't seem to know the meaning of "Stay on the topic, fulfil what you promise in your introduction". Worse still, more often than not I don't understand their version of English, including their accent. This video was another example of time wasted.

Is space time fabric is curved only from one side? Which mean space is flat.
Divyanshu Hero it means it is a fluid
Great work
This is a presentation for high school kids...
48acar19 St Xaviers is a junior college and an university. Go figure
Right. I just talked with a college girl coming from the Eastern Europe and studying math here. She told me that whatever she is studying here in the college, she knew from the tenth grade in the country she came from...There are very few really good Universities in the USA (like Stanford or Berkeley). Many of them are like...the "Liberty" Baptist University!!! LOL
I learned most of this in high school your comment is so true
48acar19 I have just started highschool last month and I understood everything said.
Excellent.
It's Leaning Tower of Pisa...not Pizza.
Ha ha.
3.58 wrong! lighth is a disturbance of the ether like sound is a disturbance of the air
Is he from Swansea ?
Excellent talk!
Reasons i think most (relativity/string theory) scientists don't understand what they are talking about: trust me its accurate calculations...that you won't understand...
The complication is the transference of information of said results due to death.
Everything was going ok till he said "believe me"!
Yeah, such a cringeworthy presentation by a highly respectable string theorist of india. Ashoke Sen will not disappoint you however
😂😂😂
My theory is that a string has two ends with a bit of string in between. That's my theory and nobody else's.
HAHAHAHA ROFL
tedgrant2 You are wrong. A G-string has no ends. Google it.
Bazinga.
i exist in a world of TEDTOKS....one is just as real as any other...
By the way, did you know that General and special relativity can be combined through the fifth Dimension? Which every 5 year old could understand and could be Explained with under a minute?
the there is somethin with infinit as carateristic in reality there is a force such have some kind of infinite carateristic. why look like many fisics dont like it.?
His talk on the subject is too opaque. One example: He has not explained why a black hole is called a black hole.
He explained the black part but not the hole part. But he didn't avoid the subject as he said he wouldn't talk about the singularity. Because his point was to introduce the event horizon to make his later point, not to talk specifically about black holes.

+Khawar Tahir There is no camera man..just cameras positioned. So you are the stupid one.
He is in India 😁😁😁
And that's why the camera pans back and forth. Wow. So quick to call people names. The PowerPoint is usually edited in later dingle dong
2.56 wrong
The string theory doesn't work if we go more deeply we will stop because time is the creator and without time (creator) nth will move or work .
Theory and hypothesis.........gravity is density is,nt it???
Who thinks he sounds like Raj Koothrappali? :P
+PGN Piano Must be his dad
From the Big Bang Theory??
Maybe.
I think he sounds more like Apu Nahasaheemapetalon from The Simpsons. I kept expecting him to say "Thank you, come again."
Another Indian so called scientific presentation: full of trivial and historical facts but no substance.
scientists should not say "believe me".
"scientists should not say 'believe me'"
String theorists are not scientists.
I'm sorry, but he's just so all over the place. Amazing information, poorly delivered.
5.14 WRONG
I feel like his accent gets thicker as he goes on... Lolol
🤣🤣🤣
Two things are infinite: the universe and human stupidity...
I'm at minute 15 of an 18 minute talk about strings, and he still hasn't gotten to strings yet... Hey, history is fun and all, but shouldn't you get to your topic?
That trampoline representation doesn't show how Gravity is acting on a object around a warped spacetime fabric..
+Just Another Atheist The point made is that there is no force of gravity but a big ball such as sun kept in the center of a trampoline that creates a depth in the space-time fabric around which the planets revolve and rotate.
Mighty Zeus High mass can create warp in spacetime but what is pulling the low mass object towards high mass??
Just Another Atheist For that you have to cover the whole setup within the warp i.e, there is no escape for the object but to go near the center.

His concept of 'relativity' is not even close in terms of depth, complexity and mathematical technicality to Einstein's.
Here you go.
String theory has to be closed as soon as possible forever. It is really a shame for scientists to develop this abstract conglomeration of non-understandable formulas...
No, it needs to be modified, not closed down.
Why would you throw a Bible that was the stupidest example
The gravity well concept is nonsense.
This guy is nuts. Does he even have any clue about what he is saying. He is only vomiting in all of the directions at the same time.
