High School Descending a Black Hole: Spaghettification or Compression?
Thank you. That explanation makes sense at one level. What has been confounding me is that the force you refer to is siad to result from a spacetime curvature, which varies as 1/r near the black hole. The 1/r indicates that near a black hole, there are sharp changes in spacetime derivatives...- Jiyong Chung

High School Descending a Black Hole: Spaghettification or Compression?
Thank you for the references. I will begin with Sean Carroll's lectures, and see how I fare.- Jiyong Chung

High School Descending a Black Hole: Spaghettification or Compression?
Thanks again, for being patient. At the start of the thread, I was seeking a simple layperson's understanding of some ideas. Based on your replies, it appears that understanding the math is required. I will look into the math.- Jiyong Chung

High School Descending a Black Hole: Spaghettification or Compression?
It seems to me that your "curved space" is the same thing as my "compressed space." If one maps a flat surface to a curved surface (e.g., say a plane on a sphere), the points on the curved surface would be closer to each other than on the flat surface, given a reference space. In the sense that...- Jiyong Chung

High School Descending a Black Hole: Spaghettification or Compression?
I have heard from, many attractive looking physicists on Youtube, that if I fell into a black hole, as I fell, I'd be stretched out or be "spaghettified. Is this correct? It seems to me that gravity compresses the free space, and that means, any object near a black hole should be compressed. If...- Jiyong Chung

Undergrad Why Can't Objects Travel Faster Than Light?
All - thanks for your replies and your patience. I know how frustrating or annoying a non-layperson's questions can be. I'm happy I learned few things!- Jiyong Chung

Undergrad Why Can't Objects Travel Faster Than Light?
That the speed of light is the same in all inertial frames - this is essentially an empirical fact, and not a theoretical one, correct? I suppose I'm asking - do the relativistic equations follow from the postulate that the speed of light is the same in all inertial frames, or is there another...- Jiyong Chung

Undergrad Why Can't Objects Travel Faster Than Light?
This seems like a compelling statement when it comes to the math. When you look at different experiments, though, such as the double slit experiment, oil-droplet experiments (in support of the pilot-wave theory) and see visual effects of the wave functions, there seems to be something physical...- Jiyong Chung

Undergrad Why Can't Objects Travel Faster Than Light?
Thanks! A few more questions (if you don't mind) - Is it even correct to think that an object is comprised of waves (e.g., at the quantum level)? Does a wave function (in the context of Schrödinger's equation) have a speed limit, and is that the speed of light also?- Jiyong Chung

Undergrad Why Can't Objects Travel Faster Than Light?
I apologize if this question is in the wrong forum section - but I could not find a proper place for what is a basic question or perhaps a nonsensical one. Is the reason why an object cannot travel faster than the speed of light because the object itself is ultimately made of waves? Is the...- Jiyong Chung

Graduate Photon direction as hidden variable in a double slit expt?
I see that now. Basically, I was pondering if there is any way that one can manipulate the hidden variables (i.e., the initial conditions) such that they cause the photons to behave differently from what is expected of them according to the standard QM. But setting the initial conditions as...- Jiyong Chung

Graduate Photon direction as hidden variable in a double slit expt?
Thanks for the reply. If I understand you correctly, you are saying that: (1) one cannot adjust the initial conditions to distinguish the pilot wave interpretation from the Copenhagen interpretation, and that (2) even if one could adjust the initial conditions, one would still end up with the...- Jiyong Chung

Graduate Photon direction as hidden variable in a double slit expt?
I was wondering if it would be feasible to set up something like the following experiment to validate the pilot wave theory. The idea here is to set up a double slit experiment, but control the initial conditions of photons emitted from a source (i.e., their directions) such that one can...- Jiyong Chung
