Multi Verse Pt.3


Ever since the beginning of String Theory, we have welcomed the fact that these special resonating strings create bubbles(Branes). Encompassing an attempt to synthesise a “Theory of Everything” where a set of mathematical equations that are able to describe all the particles that exist in our universe (Perhaps in others too) and the fundamental forces of nature and attempt to quantify and unify them in a beautiful equation. This has been dubbed the holy grail of theoretical physics. But the sheer difficulty has even alluded the greats such as Albert Einstein and Stephen Hawkins.

With String Theory at hand, these multi-dimensional strings allow anti gravitational force fields to synthesise out of nowhere. Which in turn are responsible for the these bubble (Brane) universes mentioned above. Which they then give birth to more universe, probably exponentially increasing in number.
We are suspected to be a small place in a much larger plane of existence. Living in a world of multi dimensions (More than 4). Being perhaps very small in size and scrunched into a configuration called the Calabi-Yau space plane. Noting that we could be wrapped around the a tea cup like handle in the Calabi-Yau space.

Though with any theory, it has its issues! These multi-dimensional stings are allowed to take a massive number of configurations and arrangements. This leads to a problem as it allows particles and forces to have incredibly different properties. Some numbers have been floating about in the excess of 10500 combinations. (10 with 500 zeros on the end) which is also known as the “string landscape”. Also that number is staggeringly high and far too large to realistically quantify. So this leads to massive controversy and some view string theory a charlatans game or a cop out.

In any case, String theory is still a young explanation of the universe as well as the quantum theory also. But in terms of hard conclusive scientific evidence, quantum mechanics is in the lead. But it only takes the right observations to throw quantum mechanics out of the water and place string theory in its place.

Multi Verse Pt.2


The String theory or M-theory, classifies that multi-verses are constantly budding of one another. Which uses Worm Holes as their doorway to these other universes. But the most interesting aspect of this theory is that it accounts for each universes own big bang. This leaves us with a very daunting question. Was our universe the first universe to have a big bang? Or were we products of another universe that existed eons ago. Not even in our own universe. But a much bigger one in which we stemmed from! This is really revolutionary thinking and the mathematical implications are astounding. Just the thought of this being even possible would have massive effects on the general populace. Religion would take a massive turn in its course. Quantifying this new information would open a whole world of new physics and dynamic understanding!

We have to remember that when the big bang happened. It came from a certain point. Known currently to be of a finite size and ever since it has been expanding. We have to assume that this expansion will always be of a finite size. Whether it was 12 billions years ago or yesterday. There might be more of the expanded universe now, but it will still always be a finite size, albeit huge. This leads to the question, is there anything outside of this universe? Was there anything outside of the dot before the big band. If it was infinitely small and infinitely dense it was still occupying space? Was there space outside of the dot. Or was everything that has ever existed been in that one dot? This is where string theory tries to quantify that our universe might of stemmed from a much larger universe. Making us a product of their existence. As we might do to another universe that has stemmed from us.
