Matterwave's latest activity
-
Matterwave replied to the thread High School A simple Black Hole question I can't find an answer for.Sorry if me bringing in the singularity theorems derailed the conversation. I only meant to clarify what has been proven vs what has not... -
Matterwave replied to the thread High School A simple Black Hole question I can't find an answer for.Sure, agree on that. -

Which doesn't matter, because for black hole solutions (the Kerr-Newman family of solutions), we don't use the singularity theorems to... -
Matterwave replied to the thread High School A simple Black Hole question I can't find an answer for.I'm not trying to be restrictive in terms of "physically reasonable scenarios". My statement is only restricting what the singularity... -
Matterwave replied to the thread High School A simple Black Hole question I can't find an answer for."Typically". Am I missing something? -
Matterwave replied to the thread High School A simple Black Hole question I can't find an answer for.A few points of clarification here. "Curvature increases without bound" (assuming you mean some kind of scalar measure of it anyways)... -
Matterwave replied to the thread A question about quantum entanglement.I won't belabor the point on "spooky action at a distance" since I think it's a history of science question more than a physics one. I... -
Matterwave replied to the thread A question about quantum entanglement.Missing a word "local" here. Local hidden variables was proven invalid. -

##r^{2}=h^{2}+\left(r-a\right)^{2}\Rightarrow h^{2}=2ar-a^{2}=a\left(2r-a\right)=ab\Rightarrow h=\sqrt{ab}\quad\blacksquare## -
Matterwave replied to the thread A question about quantum entanglement.Am I reading "spooky action at a distance" totally different from everyone else? I read it as "non-local". Bohmian mechanics is about... -

There are other threads that discuss the similarities and differences between thermodynamic entropy Boltzmann entropy and Clausius... -
Matterwave replied to the thread Hi! Can someone explain about Differential Equations?.You already solved the differential equation here so it might be hard to tell what it was. The differential equation originates from... -

Ok thank you -
Matterwave reacted to Roberto Pavani's post in the thread Undergrad Question about increasing laser power with
Like.
The answers above are correct. Just adding a safety note: any laser above ~500 mW (Class 4) requires proper eye protection, not just...
