This along with your other posts is very helpful. Thanks to you and everyone who responded

This was also helpful. So point-like particles were only thought of as zero dimensional because of the math explaining them, mixed with their ambiguous properties below plank level? (uncertainty), but we also see that strings can operate at around this level being under QM, clear up some of the...

and if QM applies to strings then how come string theory can marry qm with GR? I was listening to the elegant universe and it was explained like point-like particles under QM < plank length where strings lay < and GR where mass behaves classicly like strings were in this Goldilocks zone

so yes it is true that particles are not 0 dimensional since they are manifestations of a string which has length in 1 dimension, even though they can be thought of as 0 dimensional because of their mathematical representation? I feel like I am close..

So fundamental point-like particles are expressed by the vibration of a string... yet a string is two dimensional? or even more? How can quantum mechanics not apply to strings?? I don't understand the size of strings vs the size of the particles they represent? Someone please explain!

So I was listening to a book by Leonard Susskind and he was explaining what it would be like crossing the event horizon of a black hole from two different reference frames. In the first, if you were actually crossing the event horizon you would feel nothing as it is just some mathematical...

So a particle is pointlike, meaning it could verywell be massless, but anything and everything we experience is 3d, so are there any examples of something that is 2d that is also in this 3d universe?

So okay, this intrinsic Angular Momentum.. is it expressed by the literal "spin" particles create after they collide? So far I understand that particles are "born" with this property of spin. Pauli Matrices I do not yet understand. I've wiki'd spin but would just like the layman's version please.

Two basic questions here, thanks and good karma to whoever helps. my questions are: The spin of an elementary particle, is it really the physical rotation of a particle on its axis? and Can I imagine that an elementary particle looks like a three dimensional wave packet laying/distorting the...

What maths are required for complete use this book?

Thank you, mgb, my intuition remains undefeated! Wikipedia almost had me convinced otherwise.

Is this something I just have to accept? How can there be no loss of energy/heat when I've always been taught otherwise. I imagine an elastic collision to be like the electromagnetic force field around an atom that just chimes when it hits another spherical force field around a different atom...

Was looking for a more helpful response

Question above. Also, do you imagine time as a substance inside space, or, like a consequence of distance? How do you think of it?

great response, thanks mapes!
