Doc Brown, as for the unknown elements for interstellar craft are concerned, perhaps this might shed some additional light on the subject...
THE DISCOVERY OF ELEMENT 115 PAVES THE WAY TO UNDERSTANDING GRAVITIC
CONTROL
http://www.abovetopsecret.com/pages/element115.html
Element 115, the key to understanding how the ultra-secret "Black
World" has created aircraft capable of manipulating gravity and
space/time, has been identified, and the recent discovery of element
118, which decayed INTO element 114, further helps identify the
possibilities.
The most important attribute of this heavier, stable element is that
the gravity A wave is so abundant that it actually extends past the
perimeter of the atom. These heavier, stable elements literally have
their own gravity A field around them, in addition to the gravity B
field that is native to all matter.
The Key To Gravity-Control Systems
No naturally occurring atoms on earth have enough protons and
neutrons for the cumulative gravity A wave to extend past the
perimeter of the atom so you can access it. Now even though the
distance that the gravity A wave extends past the perimeter of the
atom is infinitesimal, it is accessible and it has amplitude, wave
length, and frequency, just like any other wave in the
electromagnetic spectrum. Once you can access the gravity A wave, you
can amplify it just like we amplify other electromagnetic waves.
And in like manner, the gravity A wave is amplified and then focused
on the desired destination to cause the space/time distortion
required for practical space travel.
This amplified gravity A wave is so powerful that the only naturally
occurring source of gravity that could cause space/time to distort
this much would be a black hole.
We're amplifying a wave that barely extends past the perimeter of an
atom until it's large enough to distort vast amounts of space/time.
Transmutation
We synthesize heavier, unstable elements by using more stable
elements as targets in a particle accelerator. We then bombard the
target element with various atomic and sub-atomic particles. By doing
this, we actually force neutrons INTO the nucleus of the atom and in
some cases merge two dissimilar nuclei together. At this point,
transmutation occurs, making the target element a different, heavier
element.
As an example, in the early 80's, the lab for heavy ion research in
Darmshtot, Germany synthesized some element 109 by bombarding Bismuth
203 with Iron 59. And to SHOW you how difficult it is to do this,
they had to bombard the target element for a week to synthesize 1
atom of element 109. And on that subject, this same lab has projected
that in the future they should be able to bombard Curium 248 with
with Calcium 48 to yield element 116 which will then decay through a
series of nuclides which are unknown to them, but are well known to
the scientists at S4 located within the complex of the Groom
Lake "Area 51" installation.
The length of time which an element exists before it decays
determines its stability. Atoms of some elements decay faster than
atoms of other elements, so the faster an element decays, the more
unstable that element is considered to be. When an atom decays, it
releases or radiates sub-atomic particles and energy, which is the
radiation that a Geiger counter detects.
Alien Craft
The reactor found in the alien craft at S4, as widely mentioned by
physicist Robert Lazar is primarily based on a superheavy element
with an atomic number of 115. Element 115 will be designated
as "Ununpentium" according to IUPAC guidelines. Its periodic
designation and electron configuration appear in the diagram at the
top of the page.

Two new "superheavy" elements have been made by bombarding lead atoms
with energy-packed krypton atoms at the rate of two trillion per
second.
After 11 days, the scientists working at the Lawrence Berkeley
National Laboratory, US, had produced just three atoms of element
118. These contained 118 protons and 175 neutrons each in their
nucleii.
The new elements decayed almost instantly to element 116, which
itself was short-lived. But, for that brief moment, they were the
only three atoms of these elements ever to have existed on Earth.
Ken Gregorich, the nuclear chemist who led the discovery team,
said: "Our unexpected success in producing these superheavy elements
opens up a whole world of possibilities using similar reactions: new
elements and isotopes."
US Secretary of Energy, Bill Richardson, commented: "This stunning
discovery opens the door to further insights INTO the structure of
the atomic nucleus."
Unstable combination
Atoms consist of a central nucleus surrounded by a cloud of
electrons. The nucleus consists of protons and neutrons.
But not all combinations of neutrons and protons are stable. In
nature, no element heavier than uranium, with 92 protons and 146
neutrons, can normally be found.
Scientists can make heavier ones by colliding two large nuclei
together and hoping that they will form a new, heavier nucleus for a
short time.
One of the most significant aspects of the new elements is that their
decay sequence is consistent with theories that predict an "island of
stability" for atoms containing approximately 114 protons and 184
neutrons.
"We jumped over a sea of instability onto an island of stability that
theories have been predicting since the 1970s," said nuclear
physicist Victor Ninov. He is the first author of a paper on the
discovery submitted to Physical Review Letters journal.
Atomic structure
Synthetic elements are often short-lived, but provide scientists with
valuable insights INTO the structure of atomic nuclei. They also
offer opportunities to study the chemical properties of the elements
heavier than uranium.
I-Yang Lee, scientific director of the atom smasher at Lawrence
Berkeley National Laboratory, said "From the discovery of these two
new superheavy elements, it is now clear that the island of stability
can be reached.
"Additionally, similar reactions can be used to produce other
elements and isotopes, providing a rich new region for the study of
nuclear properties."
Fast work
Element 118 takes less than a thousandth of a second to decay by
emitting an alpha particle. This leaves behind an isotope of element
116 which contains 116 protons and 173 neutrons.
This daughter is also radioactive, alpha-decaying to an isotope of
element 114.
The chain of successive alpha decays continues until at least element
106.
