I find myself being all too active on Facebook these days, doing my best to discount various ideas, theories, and beliefs that have little or no basis in reality. The topic can be anything from evolution versus Creationism; to nanotechnology; to synthetic biology; to morality and ethics; to the physical nature of reality. Sometimes these inspire me to write an entire article (like my upcoming one on world peace and prosperity) and post it here, but from time to time, I like to post shorter rants.
Recently, in “Intellectual Discussion!!! and Philosophy”, someone asked the following question:
I’m seeking knowledge on interdimensional travel and time travel. As well as Philosophy on other beings and ancient civilizations. I’m talking any theories or knowledge you think that could potentially educate me and expanded my horizons please send it or share it with me. Whether it be personal Knowledge Or articles and books please message with me. It’d be greatly appreciated
Here is my answer:
You’re not likely to get a “scientific” answer to your questions here; these fields are not really science, per se. There is *some* scientific conjecture around both of them though, so I’ll try to point you in a direction where you can explore more.
First, the notion of “interdimensional travel” the way you’ve talked about it is really two things: 1) are there more than three spatial dimension?, and 2) are there parallel universes?
These are different and you need to be careful not to confuse them. Superstring theory uses 10 spatiotemporal dimensions, for example, though most of them are tiny and internal to each string. If space had 4 or 5 dimensions (not counting time, here) then our universe would be like a flat plane you could move out of. (Read anything on Flatland to better understand this.)
But I think you’re really talking about “parallel universes” which springs out of multiverse theories. Conventionally t.v. shows and movies picture closely-related universes that can be moved between. I have a LOT of problems with this kind of multiverse theory.
If individual universes have identical or nearly-identical physical laws, what separates them? Matter, occupying more or less the same space, and capable of interactions should interact. We should be able to detect it. Some people imagine that the other 3D universes are “stacked” in a fourth spatial dimension and all lie parallel (untouching) to each other. All we need to do to move between them is travel at right angles to our 3D space (in the fourth-dimension).
Some multiverse theories talk about a new “universe” created by each quantum decision, so a lot of universes, maybe infinite. One has to wonder about the energy required to duplicate an entire universe for every quantum decision. One also has to wonder if they stack in a big 4D array and do new ones push older ones farther away or go to the outside of the array.
In my mind, a more realistic approach would be to separate universes by physical laws. If the particles of one universe can’t interact with the particles of another, they can occupy the same “space” without knowledge of each other. This idea really highlights that space is relative (to the other matter of the universe), as there would be no way to tell the relative location of matter in one universe to matter in another.
However, in my novel The Reality Thief and in this blog post (https://www.paulanlee.com/…/could-a-virtual-particle…/), I argue that very few universes ever manage to form real matter and most of them remain virtual universes.
As to time travel, IMHO it is contrary to the essential nature of the universe. Quantum mechanics and elementary particles are highly probabilistic in nature; chaos lies at the heart of our orderly universe. Non-deterministic matter is completely at odds with the block universe where time is simply another dimension like space. Above all, I think this is the most devastating argument we can make for the notion that math *is* reality as opposed to math *represents* reality (except when it doesn’t).
Books like Andrew Thomas’ “Hidden in Plain Sight” series can give you more insight into these as well.
Ancient civilizations are in the realm of historians and archaeologists; I know nothing about these areas. “Other beings” may exist in the universe (indeed, they are likely to do so), but until we meet them, they will remain pure conjecture.
