No, and no.
Dark matter may or may not exist, but it's not a hoax.
It's conceivable that we could create heavier elements than those already discovered, but their half-lives would be measured in fractions of a second.

dark matter was thought up as a way to explain certain unexplainable gravitational phenomena. dark matter has been proposed as a certain undetectable matter that is a gravitational link between stars, planets, galaxies.
it seems kind of far fetched yes, bt we already know of some matter that only interacts with gravity and weak nuclear force. for instances neutrinos have been proposed as what dark matter could be.
and any elements above about 90 are man made. meaning the only place that we find them is by firing protons at other atoms in big huge chambers. its very possible that somewhere in the cosmos these elements exist. their half lives would be extremely short, minutes at the very most, tiny fractions of a second at the least. so we couldnt possibly detect them because their half lifes are insanely short. and if there was a planet with them at its core it wouldnt exist for more than a few days maybe, the core would decay into radiation and other elements.

Dark matter can't be classified as a hoax, scientists have predicted that 90% of the matter in the universe is unaccounted for and the universe is expanding for this reason, but no success has been attained in locating this Dark Matter. Now science proposes that there must be Dark Energy causing the epaxansion, but they readily admit that if there is such a thing as Dark Energy they have no idea of where it came from, The periodic table of elements is unshakeable in it's accuracy of listing elements, heavier elements are unlikel to be fornd.

dark matter theory has been invented due to the very simple premise there is not enough mass/stars to hold any galaxy together at such great distances/speed of movement. By all accounts our galaxy should have dispersed given present accounting of speed/mass. Now here is the problem with dark matter, It does not absorb any energy/radiation. It has gravity. does not interact with normal matter other than mutual sharing of gravity fields. So they can't be 'heavy elements' because that would still be normal matter. As to what it is. there are many theories. Mond (Modified newtonian dynamics) tries to account for this blatant discrepency to the bahviour of galaxies. Wimps (weakly interacting massive particles) is the current favored theory that i just described. and Macho is another competing theory. However there is evidence of darkmatter halo's (bullet nebulae) dark matter ring around a cluster of galaxies that offer tantalizing hints that maybe wimps are more likely. But this is astrophysics in the process of being discovered. There is no real answer i can give you yet as the data is still way to inconsistant at this time. but it is DEFINITELY not heavy elements.

Dark Matter is science from laziness. Lazy scientists do not want to deal with the fact that gravity may be it s own dimension, which would change Eintstein s Special Theory (not disprove it). The matter isn t in our three dimensions, which for all practical purposes means it doesn t exist for us. That may also make Faster Than Light (FTL) travel possible - but that s another puppy in the litter.
