Is String Theory the final solution for all of physic’s questions or an overhyped dead end?

if sting theory is a wave and wave is a signal then you can use a computer to manipulate the signal wave frequenzy to change the atom mass.

Please please make a video on Loop Quantum Gravity, Abay Ashtekar and Carlo Rovelli made such a fantastic work on that theory !!! Moreover on contrary to string theory it can be demonstrate experimentally :D So please make one of your fantastic video on the most advanced and wonderfull Quantum Gravity theroy !!! A huge thank you beforehand !!
S'il vous plaît je vous en prie faite une vidéo sur la Gravité Quantique à Boucles, , Abay Ashtekar et Carlo Rovelli ont fait un travail tellement fantastique sur cette théorie !!! De plus contrairement à la théorie des cordes elle peut être vérifiée expérimentalement :D Alors s'il vous plaît faites une de vos superbes vidéo sur la plus avancée et merveilleuse théorie de la gravité quantique !!! Un énorme merci d'avance !!

Yes, a photon is a particle, but they can also behave like waves, so I urge you read up on "wave-particle duality". And all ELECTROMAGNETIC (EM) radiation is photons, whether it's microwaves, infrared, visible light, ultraviolet, x-rays, or gamma-rays. But not all radiation is EM, for example, alpha particles and beta particles are often called radiation, but they are not photons.

@Jerry's Stories It's very annoying. I'm glad I'm not the only one who feels the same way. It's almost as if these people didn't even watch the video. I'll look for it thank you for using your brain.

Yeah, it's annoying. You end up having to wade through pages of crap to get to any substance. And the newest comments are always way at the bottom. Well, anyway, I posted a discussion comment about half an hour ago, so enjoy it if you can find it.

2.09 More wavelength means more energy??? Wait! What? :-o
Jerry's Stories
Jerry's Stories - преди 3 дни
They phrased that really poorly. They said more wavelengthS, plural, with an 's'. In order to pack more wavelengths into the same space, the waves have to be shorter. This is a great channel, but they could really use some professional editing.

@hkistreet I can follow the theory and the mechanics of it all but a mathematician i am not. Im more interested in the part about multiple dimensions and the possibilities they may pose.
hkistreet - преди 2 дни
Believe me, if you're not a big time theoretical physics nerd, then describing string theory is of no use to you. It's confusing AF. But there are other channels if you're interested, like PBS Spacetime, which have videos on the subject. Good luck :)

Technically yes, but technically no....the world turtle/tortoise has been a myth in hindu/chinese and north american history long before Stephen King even wrote IT...or was born for that matter. But he definitely got inspiration for Maturin from those myths that's a no brainer.

string theory is garbage and all theoretical physicists are idiots . this sham of a discipline is a shrine to the charlatans of pseudoscience.
JazzMac36251 - преди 7 дни
I'm sure this has been mentioned, but I'm not going to go through the 15,000 comments to find it.
I'm pretty sure your characterization of Heisenberg's uncertainty principle is not correct.
It is not that one cannot know both the position and momentum of a particle because our silly instruments keep changing them - or poking them, as was implied. It's not as though we could just fix our instruments to NOT poke the bird and thus the problem could be solved. It's that our universe goes to some pretty fucking insane lengths to ensure that it is impossible to have access to reliable knowledge of both position AND momentum simultaneously...IN PRINCIPLE. Period. It's less about the observer and their characteristics and more about a fundamental hard-limit on information imposed by the laws of physics; if you have information on one, the universe will bend over backward to deprive you of information on the other.
Kind of an important distinction.
