I think there is more evidence that gravity pushes than there is that it pulls.
For some reason scientists and non-scientists alike believe that that there has to be a single unifying Theory of Everything (TOE). This goes back to before Plato and is even reflected in the modern belief in the “one true God” rather than accepting the Greek concept of multiple deities or the Zoroastrian notion of dual deities, one good, one evil. Scientists feel the need to reconcile the classical theory of gravitation and its force with the other three forces defined by quantum field theory (QFT). Several interesting lines of investigation are under way including a holographic model that treats gravity as an emergent behavior of lower dimensional quantum processes. I look forward to their ongoing research. What I am virtually certain of is that whatever creation story scientists come up with, it will be the result of natural and not supernatural causes. There is simply no need to posit the existence of supernatural causes to explain the observed data. The mistake that scientists make is to think there is only one objective truth that everyone must accept rather than individual perspectives. People who must live and eventually die (truth) don’t want truth, they want meaning.
