As Physicist and Mathematician James Clerk Maxwell put it, “Science is incompetent to reason upon the creation of matter itself out of nothing. We have reached the utmost limit of our thinking faculties when we have admitted that because matter cannot be eternal and self-existent it must have been created.”
As important as Maxwell’s works were, and his discovery, particularly in the 1860s, there are many more things he didn’t know and understand before his death, which were completed in the late 19th century, and then more so in the 20th century.
For instance, his work on electromagnetism was a major breakthrough, but it was still pretty much incomplete. And one of the vital pieces information he didn’t know about was the subatomic particle that give off negative charge: the electron.
Although, Maxwell understood electrostatic and electrical induction and magnetic flux, without knowing anything about electrons, there is a gap in his knowledge, and that’s what made his work unfinished.
It was George Johnstone Stoney who gave the name electron in 1891, but it was Joseph John Thomson in 1897 who discovered it.
With the electron, more groundbreaking discoveries were made in the next century, not just in EM and electrical and magnetic fields, but also in thermodynamics, nuclear physics, particle physics and chemistry. It also opened the door to Relativity and to Quantum Mechanics.
What you and Atanu don’t seem to understand, is science is always continuing to progress in knowledge, the knowledge is culmination of different knowledge. There is no ending to learning, no ending to knowledge and no ending to discovery in science.
The whole idea that science know everything or that there is a final mystery to everything, is nothing more than metaphysical BS claims.
Second, the Big Bang theory only covered subject on the expanding and observable universe. It make no claim to what occurred before the start of the Planck Epoch - the Big Bang - hence it doesn’t say anything about there being nothing or something before the beginning of the expansion.
The theory of the expanding universe (BB) isn’t about creatio ex nihilo (or something from nothing), isn’t about eternal universe, isn’t about Multiverse, isn’t about Cyclical Universe model, etc.
The Big Bang theory doesn’t explain everything, and there are yet some parts of the theory that remained hypothetical and theoretical at this stage, particularly the earliest epochs (eg from Planck Epoch to Inflationary Epoch to the Baryogenesis, events which all less than a fraction of the 1st second after the Big Bang). Some parts of the theory remained untested and undiscovered.
In another word, the Big Bang theory is ongoing theory, still undergoing testing. And it is the only theory on cosmology that we have some evidences for.
The other models on cosmology are still theoretical. The only reason why Multiverse, Quantum Universe and Cyclical model haven’t been trashed as failed hypotheses, is because the maths still make them feasible, even though we cannot test them at this time.
You have to remember sometimes theoretical concept eventually become experimental and empirical concept.
For instance, in 1964, Peter Higgs postulated the elementary particle known as the Higgs Boson. This particle have been purely theoretical for decades until its discovery by LHC experiments in 2012-13. With its discovery, HB is no longer theoretical.
Like Relativity were theoretical, until they found evidences or able to perform experiments to prove both Special Relativity and General Relativity.
The Nucleosynthesis of the young universe and Cosmic Microwave Background Radiation were predicted by team of physicists - Gamow, Alpher and Herman - in 1948, but it wasn’t discovered until 1964 by another team, Penzias and Wilson, thereby making the Big Bang model into a fully fledged scientific theory. Since then, over the decades that followed astronomers were able to get increasingly clearer images of CMBR, accumulating with the best images and measurements yet from WMAP and Planck spacecraft.
Maxwell didn’t have all the answers to electromagnetic fields and forces, nor did Newton with gravity and law of motion, nor Einstein with GR & SR, nor Planck with quantum physics.
They are all great geniuses and pioneers, but they all have incomplete pictures in the fields they work with. They didn’t know everything.
Your claims of neurotypical or ASD or suffering from autism to anyone who disagrees with you, to be brutally frank, is nothing more than your egotistic delusion.
