Cass...... if someone walked amongst a pile of motor engineers and said "I think the future of motoring, you know the noisy thing you use spanners on in a car, well I think the future is the flux capacitor"..... they too would instantly realise that this person does not understand the basics of engineering, or the parameters of fiction and reality in engineering.
I really don't know a better way of mirroring back to you what it is like to to have a good understanding of science and read such posts as yours.
It isn't that I/we are smarter or better than you. You are ignorant of basic science information. I was also totally ignorant of the basics, right up until about 7 years ago when I got stuck into the sciences to see what was true and what wasn't. What embarassed me more was how much the JW's hold us back because most people know the basic sciences and were were raised devoid of the basic appreciation of chemistry, physics and biology.
I hope you find these books helpful if you truly want answers..
