The universe energy's creation and its form, how many dimensions?: 2D or 3D?, a hologram?

[wickham]

Physicists have several theories on the creation of the universe. One theory is that all particles originated as waves of "strings", but were there different strings for different sub-particles? Waves and strings have to exist in something How did waves of strings somehow come into being in the void of time and space - how can this happen in a void?

Is the universe formed in 4, 5, 10, 11 or even 26 dimensions according to various theories?

Could there be a "brane" that contains the four dimensions (3 plus time) that we currently understand (more or less)? Are there many branes if there are many (even infinite) universes?

First there was the theory of the steady-state universe, then the Big-Bang universe. If we can only see 13.8 billion years into the past all around us because that is as far that light can reach us, we might think that we are at the centre of the universe Big-Bang. However everyone even on the stars 13.8 billion years from us can also see 13.8 billion years around him. It implies that everything is expanding from everyone everywhere and that must imply an infinitely large universe with an instant start everywhere at once. A Big-Bang everywhere and perhaps a infinitely large steady-state expanding for evermore!

What created the energy that enabled everything else to be created? Is the energy a finite amount? If other universes exist, do they have the same finite energy or a infinite amount? What is the nature of pure energy?

Is the universe the projection of a computer programme? Physicists has speculated that the universe we see and experience is a holographic projection. A similar theory is that the universe is 2D plus time but we experience it as a 3D projection.

A scientist says that his study of the universe has shown that it is composed of binary code which implies that everything we see and even our bodies are a projection of computer binary data.

Einstein said that space and time are inter-related, so would it be correct that these dimensions were created first and the sub-atomic particles afterwards, and then they formed into the large particles? Physicists have identified many sub-atomic particles that form the larger particles like electrons, protons and neutrons, but were they created in an order, or did all just came into existence at the same time? How were any sub-particles created?
