Big Bang doubts.

Hey all!

I'm a Biomedical Engineering student but I love Maths, Physics and Philosophy too. My knowledge about higher physics is very limited though, so I wanted to ask a few questions and see if I can get closer to the truth :P

If I am correct, the Big Bang is the name we give to the events that created the world we live in. Before that, all space time and matter was condensed in a unstable singularity that some quantum fluctuation caused to explode.

My question begins here: If in the exact instant before the Big Bang, neither space time nor matter existed - just a giant singularity, how can it fluctuate, given that force carrier particles exist within space time? How is the information transmitted if there isn't space, time or matter? How can a singularity tell itself to fluctuate or how can interact with something that causes that fluctuation in a universe in which no space time or matter exist? If this fluctuation really happened isn't it a proof that matter and space time are just one state of the Universe and that the Universe has some other state in which it doesn't need space, time or matter (yet in this state it can still be dynamic, show some properties and indeed give birth to space time and matter)?

 

Also I'm curious to know if Black Hole Singularities are theoretically the same as the Big Bag (being the only difference the amount of mass they accumulate inside)?

 

If you want my personal opinion (and this of course is not science, I hope it's OK to write it down here) I think it's time to leave the paradigm of materialism aside and try another approaches. For example there's a lot of speculation about Black Holes (from time travel to whatnot...), but I've never seen an author seriously discuss that a Black Hole could be just decomposing space time signals into frequency components for example. I think that the idea of a dimensionless frequency domain scares most scientists away but a lot of experiments (quantum entanglement among others) point in the direction of information (AKA frequency patterns) priming over matter/spacetime...

Sorry if this is too speculative for this forum, I am aware of my limitations regarding the understanding of higher physics but I just want to engage in some serious but good mood scientific/philosophical discussion because these big questions have always bothered me! :)

A singularity is in theory a point in which the laws of physics start to break down. Nobody has proved they exist.

Hardly the big bang theory makes the assumption of most of the stuff in the universe piled into one small spot. It's singularity if it exists would be far more powerful than a much smaller black hole.

Kinda. It is a model of how the universe is expanding from a hot dense state.

 

Before that, all space time and matter was condensed in a unstable singularity that some quantum fluctuation caused to explode.

 

That is just speculation. We don't have theories that can go back to the "beginning" (if there was one). It is possible that the singularity is just a result of our theories not being applicable under those conditions. There are various attempts to add quantum theory to the model; many of these get rid of the singularity. And some of them show the universe to be infinitely old.

In the classical version of the model, with a singularity, the concept of "before" is meaningless (someone else described this as like asking what is further north than the north pole).

 

In other models, the universe existed in some form and something (unknown) started the expansion.

 

Basically, the answer to your question is: no one knows. (Yet.)

They are different in a number of ways. For example, a black hole singularity (which also may not be physical) exists in your future while the big bang singularity exists in your past.

 

Also, the usual model of a black hole is based on the Schwarzschild metric which describes a static, spherical distribution of mass in an otherwise empty universe. The cosmological singularity is a result of the FLRW metric which describes the universe as being homogeneously filled with matter.
