Just a couple random thoughts I had while contemplating the development of physics. It reads:

What is a god? Among other things, one who can alter reality—that display of alleged omnipotence, to change the very fabric of nature around it as it sees fit. Then to what extent does one need to wield such power to change reality to be considered a god of some sort? I mean, humans can easily alter their natural surroundings with buildings, roads, power lines, satellites, controlled burning, canals...we have changed the face of our planet for centuries. Are we gods?

No. We change what we see based on the principles of science that we have come to understand. Of course, introduce one of our ancestral cavemen to today's world, full of rocketships, cinemas, XBoxes, and iPhones, and we would appear to be gods. To the underdeveloped mind of that time traveler, everything around him today would be both dazzlingly magical and frighteningly mysterious.

So what about a few thousand years into our own future? What if we could suddenly warp ahead in time, as so many science fiction writers and physicists alike have dreamt of doing? What might we see? Well, the cutting edge of physics now has shown some very startling revelations that could, if harnessed in generations to come, could make our future offspring appear to be as godly to us as we might seem to our hypothetical caveman.

Consider the following developments in physics:

1) Retrocausality. The concept, currently undergoing preliminary testing, that an atomic particle can sometimes travel to point B before it has left point A. Currently, we're talking trillionths of trillionths of seconds of time, but still a measurable phenomenon. If found to be true, this would shatter so much of what we have held dear in science since its inception, because knowledge in science comes from logic and reasoning, which itself is something applied to observable cause and effect. If cause is shown to be retroactive—that is, if cause and effect can work going the opposite direction of what we consider a one-way street called “time”—then we would have to completely reexamine what we see as being cause, effect, and the science that stems therefrom.
2) Scenario/range laws. Physics is showing us that certain laws or theories that we take as being fact only exist on certain scales, or in certain phenomena, or in certain places. Gravity, for example, as we understand it currently, only explains forces that occur on very large bodies. It does not work, however, on smaller bodies. Consider that the Moon revolves around the Earth due to gravity, but I can't get a paperclip to revolve around my own body. And it seems to apply even less as the scale gets smaller. In fact, there seem to be a completely different set of rules to govern the atomic world and why electrons revolve around nuclei than what gravity can explain. Black holes, also, have created their own myriad of mysteries, many of which are still trying to be understood, showing that some rules only apply in certain scenarios. And for another example, certain new evidence is suggesting that the laws of physics and math that we take for granted as being the set rules of all existence, are themselves capable of evolution. Some physicists believe that the laws of physics were different towards the singularity of the big bang, and other thoughts have also been formulated that suggest these same laws may even now be different towards the outskirts of the known universe.

All these concepts, considered together, form an entire grocery list of possibilities for changing reality around us on a much more fundamental, seemingly magical level. What if we could take the tiny, nanoscopic wormholes theorized to exist for a fraction of a split second and expand them to create space-time travel? What if we could understand the nature of evolving, changing laws over space-time so that we could change those same laws—laws like gravity or thermodynamic—here? What if we could understand how retrocausality may restructure our concept of cause and effect and therefore change the past behind us, or better anticipate events ahead of us? Would this future society with this knowledge implemented appear more godly to our current generation? Would they be able to manipulate us? If retrocausality turns out to be true on a large and fundamental scale, could they be affecting us even now?
