I am humbled by what science CAN prove, I find it amazing and wonderful. I'm just not sold on what it has yet to answer, or has answered using conjecture, then teaching it as fact to our fellow man.
Light elements like helium, deuterium and lithium formed in the first hot moments of the universe's existence, according to a theory called Big Bang nucleosynthesis, but from what we could tell, the actual levels of lithium in the in the universe were much different than the model would suggest. From looking at the oldest stars in our galaxy, it seemed that there was about 200 times more of the isotope Lithium-6 than Big Bang nucleosynthesis accounted for, and up to five times less of Lithium-7. "Using more sophisticated physics and powerful super-computers, we managed to remove the systematic biases that plague traditional modeling and have previously led to false identifications of the 6Li/7Li isotopic signature," Lind says in a statement. The team's observations of lithium levels were more in line with the Big Bang theory's predictions.
"Our findings remove much of the stark tension between 6Li and 7Li abundances in stars and standard BBN, even opening up the door for a full reconciliation," Lind explains. www.popsci.com...
Bu "science" isn't teaching the Big Bang theory in schools, human teachers are.
I'm not sure what schools you went to or what your level of education is and I don't want to make assumptions so... I've never had a teacher tell a class that it is a 100% proven fact.
It's always been presented as the prevailing theory accepted by the majority of scientists and knowingly has a few kinks in it. It has always been taught, to me at least, as the best scientific explanation we have and while there are some gaps, there is still an overwhelming amount of data to support it. What about Big Bang do you disagree with and why?
Well if that is the case, then it is just another example of the school system
misrepresenting truths abiout science.
I am certain that if the conventional wisom in schools was that our model of the universe was just a theory, and it has yet to be proven true, much more fascination would come from the student. Perhaps we would have more kids growing up wanting to solve the case.
Nevertheless, I am happy that this thread has turned into an education piece rather than a few people calling me stupid because I ask a few questions outside of the standard model of the universe.
IroncladFT But those human teachers are TOLD what to teach by a state or federally approved curriculum and teachers CANNOT deviate from it. And those teachers are given text books purchased by said states, ALL of which say, IN THE BEGINNING, BILLIONS of years ago, there was a big bang. NOT, MAYBE there was a big bang, NOT we THINK there was a big bang, it says there WAS a big bang. None of the books or teachers talk about what was BEFORE, except a few who throw out the M-Theory to try and explain it. For the most part, our educational institutions ignore what came before and their starting point is the small collection of mass (from where) that somehow gained its own energy, then enough energy to spin (as i was taught WAY back in the 80's), and spin so fast it eventually blew up, giving us what is now our universe.
The High School I went to in PA did in fact teach it as fact. It was the ONLY thing discussed as to how all of this came to be, and still is the ONLY thing taught. Now I will say this, I may have learned more in college had my majors not been History and Criminal Justice, but having had discussions with science professors and science majors on campus, they ALL said the BBT was fact and that is how the universe was created. There was no MAYBE about it when talking to them, even when they couldn't explain where the energy came from to create such a blast.
There are many misconceptions surrounding the Big Bang theory. For example, we tend to imagine a giant explosion. Experts however say that there was no explosion; there was (and continues to be) an expansion. Rather than imagining a balloon popping and releasing its contents, imagine a balloon expanding: an infinitesimally small balloon expanding to the size of our current universe.
Another misconception is that we tend to image the singularity as a little fireball appearing somewhere in space. According to the many experts however, space didn't exist prior to the Big Bang. Back in the late '60s and early '70s, when men first walked upon the moon, "three British astrophysicists, Steven Hawking, George Ellis, and Roger Penrose turned their attention to the Theory of Relativity and its implications regarding our notions of time. In 1968 and 1970, they published papers in which they extended Einstein's Theory of General Relativity to include measurements of time and space.1, 2 According to their calculations, time and space had a finite beginning that corresponded to the origin of matter and energy."3 The singularity didn't appear in space; rather, space began inside of the singularity. Prior to the singularity, nothing existed, not space, time, matter, or energy - nothing. So where and in what did the singularity appear if not in space? We don't know. We don't know where it came from, why it's here, or even where it is. All we really know is that we are inside of it and at one time it didn't exist and neither did we.big-bang-theory.com...
What about the experiments done in the late 1990's (while I was in the Army I tried to educate myself sometimes..lol) when they slowed light down and found out they could also speed it up. So if we can do such things with light, how do we actually KNOW light is a constant and reliable to use for answers we seek?
Red shift could then be completely different travelling from BILLIONS of miles away not? Same for Blue Shift, wouldn't that be possibly effected? Not to mention, if even the shifts ARE 100% accurate and fact, that still doesn't prove a BB created everything we know.

Another question for you guys.
If we see light that took millions of light years from the Big Bang to get to us, how did earth beat that light to the present time? It seems as is we would have to travel faster than light to beat its arrival if we all came from the Big Bang. Or am I looking at it wrong?
