TY to the thread "a neutron star collapses - where's pauli?"

Specifically, what happens to the identical fermions in a neutron star as the neutron star collects additional mass that makes it into a black hole. Fermions cannot occupy the same state according to the Pauli exclusion principle, what happens to them in the black hole?

I found Science of Morality in Wikipedia, which was the right topic of my search. According to the Wikipedia article, "Here, moral scientists purport to possesses a more than adequate working definition: something is morally good if it promotes the flourishing of conscious creatures." On the...

Thanks, I read Wikipedia on Social Darwinism; it was interesting but not exactly what I had in mind. I'll check Evolution of Social Behavior--thanks.

Yes, it must be speculative, as the earliest code of ethics was probably during prehistory. Thanks, I am familiar with Jane Goodall''s work. I think there are many examples in the animal world, including all the apes but especially chimps. Thanks for the Yerkes and Social Darwinism...

Please include works of fiction as references; I do not intend to publish--just curious.

I am looking for references that explain how ethics evolved from human needs (e.g., community) and instincts (e.g., fight/flight).

I did not think of an infinite redshift and infinite wavelength within a finite universe as possible; thus, it took a while to wrap my mind around it. It makes more sense than anything I thought of. Thanks.

https://www.physicsforums.com/showthread.php?t=110906 says, "1) Theres no theoretical upper limit on the wavelenght of the EM-spectrum. On the horizon of our visible universe there's an barrier of "infinite redshift". Also, EM-radiation radiated by a body falling into a black hole will also...

First, is one light wave (or perhaps half wave) possible that stretches across the universe, such that each end of the wave (or half wave) is on opposite sides of the event horizon of the universe, which is the distance light has traveled since the beginning of the universe. Second, is this...

OK, what does it mean to us when a string ends as an N or D in one of our four dimensions? Can we observe such an end?

http://en.wikipedia.org/wiki/D-brane says, "The equations of motion of string theory require that the endpoints of an open string (a string with endpoints) satisfy one of two types of boundary conditions: The Neumann boundary condition, corresponding to free endpoints moving through spacetime at...

Which explains why dark energy. It is an enigma that is neither energy nor force. Maybe it is a random occurrence with no reason--something that cannot be known.

TY :biggrin: Either is possible, AFAIK, but I feel compelled to ask why is inflation accelerating--that seems to need a force.

Thanks for your reply. Ytivarg doesn't work quite right, as I understand it. Space-time can inflate faster than c, but gravity waves are limited by c. Thus, as I understand space-time could not inflate faster than c if (gravity^{-1} = ytivarg) were the driving force.
