Rutherford, planck , bohr jumpstarted the 20th century physics .

and they _always_ have few percent of protons and electrons — every single neutron star .

and they _always_ have few percent of protons and electrons — every single one of them .

protons can generate neutrons and neutrons can generate protons . why are there no nuclea with only neutrons ? — these could be as big as you want because there is no electric repu…

nucleus is extremely fluffy by general relativity standards . for black holes the mass and size are linearly proportional . the solar mass black hole has few mile size and has dens…

nonsense . heavy nuclea are bound states of many constituents . no different from grain of salt . grain of salt can be much heavier than planck mass (which is about few micrograms

Short answer: talk about quantum wells in this context is meaningless .

Not metaphors . We know these are out there — we just don’t know a lot about them. The situation is similar to atoms in second half of 19th century : we knew they are there , we kn…

the funny thing is that the calculation in this article misses the point, especially in the Feynman context. First, beyond all trickery, the log(alpha) answer might suggest that so…
