It's just a "Theory"

In a previous thread which is now closed, a member here had a terrible time understanding the use of the word "Theory" in scientific terms. I hope this video helps.

Here is how Theory is used in Science:
In modern science, the term "theory" refers to scientific theories, a well-confirmed type of explanation of nature, made in a way consistent with scientific method, and fulfilling the criteria required by modern science. Such theories are described in such a way that any scientist in the field is in a position to understand and either provide empirical support ("verify") or empirically contradict ("falsify") it. Scientific theories are the most reliable, rigorous, and comprehensive form of scientific knowledge,[2] in contrast to more common uses of the word "theory" that imply that something is unproven or speculative.[3] Scientific theories are also distinguished from hypotheses, which are individual empirically testable conjectures, and scientific laws, which are descriptive accounts of how nature will behave under certain conditions.[4]


You see when a scientific theory stands the test of time and peer review, it becomes proven, i.e. fact. The Theory of Evolution is as much Fact as is the Theory of Gravity.

It is the THEORY of Evolution and the LAW of Gravity! Two seperate scientific principles.

"The test of time and peer review" DOES NOT PROVE a theory!

'Facts' based solely on faith cannot be tested (unless you count a lack of proof, proof.)

Only one's own faith can be tested. And proven only to oneself.

Ok, let's just throw out Maxwell's Theory of Electromagnetism and while we are at it let's toss all this technology that we use every day that relies on it. Afterall, it can never be definitively proven since it's just a theory and all this stuff may just randomly stop working one day as the theory could be flawed.

Right?

The one's who have true faith don't need or want proof.
God's word, as written in the Bible, is good enough.

WRONG! Theories have their place in the scientific method. But they are not FACT, yet. They do an excellent job of explaining the evidence we have already observed. A good example of this is the Geocentric Theory (which by the way was not started by The Church but by a Greek named Ptolemy). It explained the movements of the planets very well and stood "the test of time and peer review". Even Galileo's Heliocentric Theory wasn't completely correct and was not PROVEN until 1838 (F. W. Bessel) using the principle of parallax.

Good point! Newton's law of gravity isn't even as strong as the theory of evolution.

"Laws differ from scientific theories in that they do not posit a mechanism or explanation of phenomena: they are merely distillations of the results of repeated observation. As such, a law is limited in applicability to circumstances resembling those already observed, and may be found to be false when extrapolated."

So you willingly want to stand in blinding ignorance?

The Bible has stood the test of time and peer review. Must be a fact that it is the Word of God.

You obviously don't understand how the scientific peer review and theories work.

Right and wrong, but mostly wrong, given the context you're thinking.

A scientific law describes a specific event in a specific situation. Newtons Law of Universal Gravititation lets us describe how an object falls, which way it will go, and how fast it will accelerate. What it does not tell us is why gravity acts, what creates gravity, or what is gravity. That is what the Theory of Quantum Gravity is being developed for.

You're thinking that the process of science is a progression from hypothesis --> theory --> law. That's not correct. There is no amount of evidence that turns a theory into a law. One is a pattern, the other is an explanation of how and why it works.

So, explain it to us ignorant believers.

Start with the once accepted theory that the Earth was flat.
Then tell us about how it was believed that the Earth was the center of the universe.
Please include the theory that an airplane could not fly faster than the sound barrier.
Don't forget the theory of "man made" global warming.

And finish up your presentation with the theory about how man evolved from animals and that there is no God.

When I went to college for Manufacturing Engineering Technology it was 50% hands on Machine Tool Practice and 50% Theory. Theory included college algebra, physics, statics, ect. Theory is the science that backs the practice.

Please state the LAW of gravity.

Depends on the mass.
