One asteroid in the solar system's asteroid belt is so dense that scientists theorize that it has new elements that are off the (Periodic Table) charts. The asteroid's name is 33 Polyhymnia. CUDO's to the scientists for discovering this (CUDO is short for compact ultradense object, if you like to nerd out on that sort of thing). Asteroid 33 Polyhymnia is so dense it may actually contain elements never before seen on Earth, according to a new study
If Bohr’s theory and Einstein e=mc2 is correct, upper limit of possible elements is 137 before the electron v > c Humans have only observed 118. Science!
Must mean the electrons can only orbit the nucleus so high before they must exceed the speed of light in order to stay in orbit.
Makes sense. I assumed the V was velocity. So Velocity exceeds the Speed of Light. I wonder if the laws of physics could break down at the quantum level. Kind of like quantum entanglement.
Almost correct. It's not the upper level of orbit that is the problem, but the lowest one. This is a bit of an oversimplification, but the larger the nucleus of an atom the larger the positive charge (bigger nucleus = more protons). Therefore, the lowest orbit of electrons must spin faster to stay in orbit because of the increased positive charge. I don't remember the exact equation, but the Bohr model places the absolute upper limit at 137 where the 1s level of electrons are very near the speed of light. Electrons are not massless so they cannot actually achieve the speed of light. In theory, once we get to about Z=124 (largest in existence is Z=118), an element cannot exist for more than a split second before fission occurs.
Not necessarily. Gravity is dependent on mass and distance, not density. If you had two spherical objects of different densities but identical mass (the more dense object would be smaller), they would theoretically have the same gravitational field per Gauss' Law. The only place density really comes into play is on the surface of the object, but again it's more mass than density. You'd weigh the same on two identical mass objects with different densities, but weigh more on the more dense of two identically sized objects. Make sense?
Genius WDG. It could also mean that c trained an alligator to eat v, because c was more powerful and was going to destroy v. At least that is how I explained greater than/less than to my 2nd grader.
It's kind of a "what's heavier - a pound of lead or a pound of feathers?" situation. If two asteroids have the same mass, they would have the same gravitational field but the denser asteroid would take up less volume. You could get closer to it's center of mass and experience a higher 'surface gravity', but at sufficient distance (say 2 or 3 times the radius of the widest asteroid) they would exert the same pull.
