What came before the big bang?
https://www.washingtonpost.com/national/...story.html

EXCERPT: [...] a “small platoon of physicists” who focus on figuring out such things as what happened at the very first moment of the big bang, whether time or anything else existed before it, and exactly how we distinguish the future from the past. And they expect, sometime in the next 50 years or so, to have some real answers....



Mysterious radio signals from space test Einstein's General Relativity theory
http://news.psu.edu/story/386147/2016/01...relativity

EXCERPT: A new way to test one of the basic principles underlying Einstein's theory of General Relativity using brief blasts of rare radio signals from space called Fast Radio Bursts is 10 times to 100 times better than previous testing methods that used gamma-ray bursts [...] Fast Radio Bursts are super-brief blasts of energy -- lasting just a few milliseconds. Until now, only about a dozen Fast Radio Bursts have been detected on Earth. They appear to be caused by mysterious events beyond our Milky Way Galaxy, and possibly even beyond the Local Group of galaxies that includes the Milky Way. The new technique will be important for analyzing the abundance of observations of Fast Radio Bursts that advanced radio-signal observatories, now being planned, are expected to detect....



Stellar revelations
http://www.eurekalert.org/pub_releases/2...010416.php

EXCERPT: Using a recently developed technique to detect magnetic fields inside stars, a group of astronomers -- including Matteo Cantiello and Lars Bildsten from UC Santa Barbara's Kavli Institute for Theoretical Physics (KITP) -- has discovered that strong magnetic fields are very common in stars. The group's findings appear in the journal Nature. [...] Previously, only a very small percentage of stars were known to have strong magnetic fields. Therefore, current scientific models of how stars evolve do not include magnetic fields as a fundamental component....

What came before the Big Bang?
The actually meaning of a Big Bang isn't that everything emerged from an Explosion, it was actually meant as a way to explain the speed of Expansion as being "Explosive". There is still a lot of misconstrued rationale because of that terminological mix-up.

I and some others assume what came before is actually "us". At some point in our future (perhaps when humanity actually knuckles down and gets on with it), the universe will be built. We will "simulate" the beginning, however the smart money is that we'll augment that reality into the one we already have so that both the simulated beginning and the world that we exist in become one in the same.

This will then mean that all time that occurs after it's inception is actually viewable by a future observational position which in turn then brings into question if that observation platform has then the capacity to interact further with the universe as it "evolves" or if it's mission statement would actually reflect about observation alone. (no interaction).

In any sense I don't believe that cosmologists are going to be able to unravel the universes beginning without understanding how to look from outside the box.

Thank you! I was almost on the verge of claustrophobia thinking the universe had already contracted since I last read about it!

As for what came before the BB, I'm thinking of a fractal metaphor now, and of time at every point in itself swirling up out of infinitesimal patterns to emerge as the here and now. The dilemma of preexistence before time is suspiciously linked to that of emergence and how novelty springs up at every moment. Time is saturated with infinity at every point in itself, and not just at the BB. Things can happen without a cause at any time, not just 12.5 billion years ago. We have never escaped that "beyond spacetime" edge where the New explodes out of nothingness. That edge has simply curled up within itself and embedded itself in the very fabric of all happening at every point.
