MMotore reacted to FreeResearcher's post in the thread Undergrad Rotation curve in spiral galaxy velocity and uniform velocity dispersion with
Skeptical.
Entropy is not an additional form of mass, but in some approaches it can produce an effective extra acceleration at low accelerations... -
MMotore reacted to Line_112's post in the thread High School Contradictions in the Distribution of Gamma-Ray Bursts with Skeptical.
Galaxies can appear and die. But overall, what we call the Universe must be much older than 13 billion years, since otherwise many...

MMotore reacted to Line_112's post in the thread High School Contradictions in the Distribution of Gamma-Ray Bursts with Skeptical.
Even ignoring the Milky Way's disk, the map doesn't have a very isotropic distribution. I've already learned intuitively to recognize...

MMotore reacted to Line_112's post in the thread High School Contradictions in the Distribution of Gamma-Ray Bursts with Skeptical.
The lack of weak bursts in the overall statistics is easily explained by the fact that, given a constant gamma-ray burst power, most of...

MMotore reacted to Line_112's post in the thread High School Contradictions in the Distribution of Gamma-Ray Bursts with Skeptical.
But the weakest flares no longer pass through the scattering medium of the galactic disk. Therefore, their number at the equator should...

MMotore reacted to Ibix's post in the thread High School Contradictions in the Distribution of Gamma-Ray Bursts with
Like.
Indeed. That's why he needs to do some maths. Gamma ray scattering by the interstellar medium is a key plank in his belief - he needs it... -
MMotore reacted to Dale's post in the thread Insights Thinking Outside The Box Versus Knowing What’s In The Box with Like.
After a severe thread cleanup, and several thread bans, this thread is reopened. Please remember that we want to keep PF productive...

MMotore replied to the thread Insights Thinking Outside The Box Versus Knowing What’s In The Box.And the correct solution to that will most probably come from the other knowledge and tools already in the box. That's the point. I have...

MMotore reacted to renormalize's post in the thread Insights Thinking Outside The Box Versus Knowing What’s In The Box with Like.
You've moved the goal posts by adopting an idiosyncratic definition of the "box". In reality, the box is simply the body of all the...

MMotore reacted to ShadowKraz's post in the thread Insights Thinking Outside The Box Versus Knowing What’s In The Box with Skeptical.
There is a difference between the 'box' and knowledge. It is in how one treats the knowledge. If it is assumed to be completely solid...

MMotore reacted to gentzen's post in the thread Undergrad Single vs. Double slit coherence clarification please with Like.
She is unhappy with the way popularizers use the double slit experiment to illustrate wave-particle duality. She seems to try to better...

MMotore reacted to FactChecker's post in the thread Undergrad Is this another "paradox" or a veritasium mistake? with Like.
IMO, Veritasium tries hard to be correct. It might be nice to leave a comment on the video about the mistake. UPDATE: I see that the...

MMotore reacted to A.T.'s post in the thread Undergrad Is this another "paradox" or a veritasium mistake? with Like.
I'm not sure if this is the case here, but I think it's common to have the graphics done by someone else. And at some point, one might...

MMotore reacted to Chiara's post in the thread Undergrad On the Quantum Mechanics of Entropic Forces with Skeptical.
"Black" means: "It does not shine". This is the prediction of general relativity. A non-zero BH temperature means: it does shine, it...
