From what I've read, they've only made a few atoms of element 115, which had a half life measured in thousandths of a second.
Even that is disputed by many scientists.
Therefore, I can't understand where they would get all the element 115 to do all these things.
Kind regards

Perhaps you can harvest stable isotopes of Uup (Ununpentium, the real, albeit temporary, name of "element 115") from very dense and old stars, where heavier elements such as this would have had time to form in large amounts.
"But the problem is that were you to "harvest" as you put it something that's stable in that star but not on Earth, and you bring that something and put in on the Earth, it's now subject to the forces on Earth, which is, much lower gravity than the star where you got it from. Therefore you're still stuck with the same problem once you bring it from the star to Earth, if such a thing were even possible. That is, once on Earth, it's unstable, the fact that it may have been more stable on or in the star only helps while you're in that environment."

Generally speaking, a high-energy environment (core of a star) is less stable than a low-energy environment (mineral deposit in Earth-like planet). So basically, if there were an isotope of this special element that were stable in the core of a large old star, it should be stable in earth's lower-energy environment.
To my understanding the above is correct, though it might not be. Please correct me if so =)

A number of experiments have shown that decay rates of naturally-occurring radioisotopes (for decay modes other than electron capture) are, to a high degree of precision, unaffected by external conditions such as temperature, pressure, the chemical environment and electric, magnetic or gravitational fields.
That's not quite true. Take Uranium for example. Where was it created? As the best theories go, it was forged in the core of a 2nd-generation star that preceded our solar system. Same goes for all the elements. They were all created in environments wildly different than they currently reside (in some cases), and are entirely stable. Generally speaking, a high-energy environment (core of a star) is less stable than a low-energy environment (mineral deposit in Earth-like planet). So basically, if there were an isotope of this special element that were stable in the core of a large old star, it should be stable in earth's lower-energy environment.

Sorry about the double post I was trying to edit John Hutchinson's name into the floating bowling ball - anti gravity clip posted.
