Here's something that occured to me - we supposedly don't have 115 in our solar system because our part of the galaxy lacks the massive supernovas (hypernovas?) required to fuse this superheavy element right? However Zeta Reticuli (assuming that is where the Greys come from) is right in our cosmic backyard - a mere 39 light years from Earth...
Basically what I'm saying is that if the conditions for 115 aren't right here, why should they be right in a solar system that in relative terms is very, very close to us?

Well first of all I don't agree with you that Zeta Reticuli is "close to us," even when you bring the size of the universe into perspective.

I said it was close in relative terms - given that the Milky Way is between 80,000 to 100,000 light years in diameter and Zeta Reticuli is only 39 light years away this hardly seems like an unreasonable assertation.

I see what you are saying. It is a pretty short distance when you compare it to the big picture. However, one light year is roughly 6 trillion miles if I am correct... So regardless of how large the rest of the galaxy is, 234 trillion miles is plenty far for there to be all kinds of different elements and who knows what else...

Oh yeah, that's definitely true. However a hypernova is an exceptionally rare event (estimated to occur in our galaxy once every 200 million years) and should affect stars within hundreds of light years of the epicentre so if 115 does require a hypernova rich area of space to exist it might seem strange that those conditions exist within Zeta Reticuli and not here.
Of course this is by no means to say that its not possible, I just thought it was something interesting to keep in mind.

A very interesting thread.
I have given little thought to really heavy elements that are theoretically possible up to atomic number 137. Indeed, an area of space which had denser starting materials should very well form heavier elements than we see in nature. Our naturally occurring elements on Earth stop at uranium, element 92, I believe. I see no reason why the periodic relationship of the elements would not continue higher than we have here. I understand what John Lear is telling us about element 115 and it is very logical. As a scientist, but not a physicist, I only have a basic understanding of quantum theory, so the physicists here please forgive my bad science and correct me as required. I believe there are 5 possible isotopes of element 115, and the one with 184 neutrons would be the stable one.

As an example, suppose nucleosynthesis for the materials which formed our solar system had stopped before thorium. Would we ever develop nuclear fission reactors? No, never. Probably even nuclear fission itself wouldn't have been discovered for a while---probably spontaneous fission of accelerator synthesized elements, far earlier than chain reaction fission.

There's an assumption here that "Zeta Reticuli" or wherever ETs supposedly live is also where they mine the E115.
That needn't be the case. Japan has no petroleum. They buy it from Saudi Arabia.
Once ETs get some they can migrate and go live somehwere else, as long as they maintain some control over the E115 source.
E115 is like 'spice'.

From memory: (its been a while) didnt bob even go into some detail explaining (for example) that element 115 was an orange colour?
if this is the case how credibile is it that someone could guess such a detail?
The the actual element the colour that he predicted?
And is it easy for a scientist to determine this from theoretical calculations?

I wonder if the 115 Bob had (assuming that is what he had) could have "rusted" and become a 115 oxide? Plutonium for example is normally a silvery white metal, but when it undergoes oxidation it can have any of the following colours depending on the ion (source: wikipedia)
* PuIII, as Pu3+ (blue lavender)
* PuIV, as Pu4+ (yellow brown)
* PuVI, as PuO22+ (pink orange)
* PuV, as PuO2+ (thought to be pink)
* PuVII, as PuO52- (dark red)

However, as I recall, Lazar said it [Element 115] had anti-gravity properties... and he certainly missed the mark on that point as well as on other points.
