    Doppler effect vs expansion effect on wavelength

    Could you please clarify for me how much each of these contribute to the red shifting of light from distant objects? It seems to me that red shifting of light from near by objects i.e. within our galaxy would be affected more by the Doppler effect whereas for intergalactic objects the red...

    Is there a maximum mass for a black hole?

    Oops, I found an error in my original calculation :eek:. New calculation gives me about 2e41. Yes, I only used Newtonian physics, thought about relativistic effects, but not sure what those would be or how to calculate. I ignored any effects from the mass in the rest of the galaxy, not sure...

    Is there a maximum mass for a black hole?

    I recently tried to calculate the mass of the black hole in the center of the milky way and it came out to 1.8x10e+53 kg, that can't be right, what's going on?

    Solving Speakers Popping Problem

    I believe you could just solder a small capacitor across the terminals of the speaker, as a low pass filter, though I don't know what size would be good, perhaps 1 pf.

    Can AI Truly Learn Independently Without Free Will?

    Because the universe started at a single point, everything in the universe can be traced back to that point, and because everything is based on cause and effect nothing is really random. Everything is based on what happened since the universe started at that single point and all the...

    Can AI Truly Learn Independently Without Free Will?

    I don't believe in free will, in fact what I am writing right now is based on more nuerons in my brain wanting to write this, than those that want not to. How my neurons got into that position, I am not sure, based on random events I suppose. But what is random? Randomness is events that...

    Could there be an edge to the Universe?

    How can there be an edge if it is 4 deminisional (at least), the universe is expanding 4 deminsionally, if time is the 4th deminision then we must already be on the edge. i.e. Since the universe was smaller in the past and will be larger in the future, that means that currently we must be on...

    Why does the permeability of free space have an exact value?

    permeability What if I told you that the permeability of free space was increasing due to the expansion of the universe? That would mean that the speed of light is also increasing. Which would mean that light emitted from distance stars billions of years ago would actually be traveling faster...
