Fusion occurs when the right position of sub-atomic particles occurs. Heat and pressure speeds the process. All elements will fuse and become heavier elements. It just takes more time when heat and pressure are missing.
The extremely heavy elements will defuse and decompose and recombine in the center of stars. In planets the process occurs slowly but still occurs.l but is deterministic toward heavier fusion. There is no need to get the heavier elements from off planet sources. They will eventually appear here in the center of our planet and certain flows will bring them to the surface in small amounts.
In space most of the soup emitted by stars condense back into hydrogen over long periods of time. That is why it is abundant. It is much easier to combine the starry exhaust as it is sub-atomic and will easily combine into hydrogen. Hydrogen is simple and it is the first stage of sub-elemental combination.
The electromagnetic particle output of stars will combine over long periods of time and shift towards the heavier sub-atomic elements until they are hydrogen. Redshift is a good example of this. A
We, as yet, have yet to define the range of sub-atomic elements. We are just beginning to understand the sub-atomic forces that keep particles in close proximity. We need another Mendeleev to mentally organize these combinations.
It is right that we resist change. Resistance insures the forward momentum of ideas. Resistance cements the next step much like a check valve won't alow fluid to reverse through a pipe, so does resistance work to resist a backward step when the forward resistance has occured. The pressure of truth will insure the step forward remains. Resistance also allows us to better examine any change.
That is why theories like the Big Bang will have a lasting impression in the minds of most scientists. That and the fact that no better theory existed to replace it. Condensation or slow fusion does replace it. It explains why it's possible to have blue galaxies at the edge of our universe. These galaxies are just now beginning. Currently, an extension of the Big Bang, that is, multiple Big Bangs or multiple universes try to make sense of these blue galaxies.
Of course, if they are in process of formation it implies a beginning and also implies intelligent design of the universe as a whole.
Science leads to philosophy and philosophy leads to religion and religion leads to truth. We fashion our theories of our gods. We haven't accepted them as they really are. We live in a steady state universe where planets grow very rapidly and become stars and stars die and are reborn.
If the Universe disappears every few billion years then there is no intelligent design and life is a cold hearted master wielding fiery elements.
