It is a verified and undeniable fact of the world we live in that he half life of Uranium to Lead is 4.47 billion years.
True
Radioactive Decay is an undeniable fact of the world we live in that has been repeatedly verified.
True
It is a fact of the world we live in that the Earth is billions of years old. Humankind knows that. The theory that the Earth is billions of years old is as much of a fact as the theory that the force of gravity exists is a fact.
False.
Comparing radiometric dating to gravity shows your lack of knowledge about how science works. We can observe gravity by simply dropping a ball. You can't observe rocks aging billions of years.
Now, here is the whole key, like I have mentioned dozens of times but you just plain won't listen.
Radiometric dating techniques make major assumptions. Specifically for U-Pb, the first of which is that 100% of the lead in the rock came from uranium. This assumption is a vast leap since there is obviously a chance that there was some lead originally in the rock. There is a chance that some of the lead came from the 26 radioactive isotopes that also are in the U-Pb decay chain, 8 of which are major step changes and therefore realistic possibilities. They also assume that over these billions of years as water has passed over/around/through this rock that ZERO amount of uranium or lead has leached in/out of the rock, that it has been in a hermetically sealed bag basically (yes, I am over simplifying).
Also, gravity is not a theory, it is a Law, which is much different. The Gravitational Theory is how gravity works, the Law of Gravity is the equations behind the fact that it exists. Basically the Law helps us understand what gravity does on a large scale, the theory tries to explain (with an unproven particle called the graviton) HOW it works on the microscopic level.
You are mixing up scientific laws with scientific theories.
The Laws of Thermodynamics are facts, how heat moves, entropy always increasing, etc.
The Law of Gravity is a fact.
Newton's Laws of Motion are facts.
Einstein's Theory of Relativity is a theory, a very good/well accepted model of how things work in the atomic sized world along with how things work as we approach the speed of light. It has never been proven and there are some competing theories as well as some "bridge" theories like string theory to fill in the holes between relativity and macroscopic laws (Newton's).
Gravitational Theory is a very good/well accepted model of a particle causing gravitational force. We KNOW the force is a fact (see the Laws of Gravity), what we have to theorize is how that force is created. It has never been proven and many particle physicists are still trying to find/observe said graviton.
The Big Bang Theory (not the TV show) is a very good/well accepted model of how the universe expanded fractions of a second after it started. It is not a fact and there are some other theories as to how the universe began.
Evolutionary Theory is a very good/well accepted model of how live transformed on this planet. It has not been proven and therefore not a fact.
I hope this helps in explaining the difference between fact and theory in the scientific world.
Before you jump up screaming about major scientific theory having a different threshold/definition than the normal English definition of theory. I am WELL aware, and you have yet to see where I have NOT said they are very well accepted theories.
However, there have been many scientific theories over the centuries that have eventually proven to be false.
One of which was that the Earth was the center of the solar system. Early astronomers saw the fact that it appeared that everything revolved around the Earth. They came up with fancy orbits that included orbits integrated inside orbits (like the picture) with the Earth off center to explain the path that the planets make in the Earth's sky. With what was known at the time, it was a good/viable theory as to the way the solar system looked. It fit the evidence they were able to measure and was widely accepted. However, it was obviously proved false once more modern measurements were able to be taken. It wasn't a small refinement of the model either, it was a MAJOR change to the theory. Just like when Darwin proposed evolution, it was a MAJOR change to the prevailing theories. There is nothing to say that there won't be another MAJOR change to how life developed as we refine our observation and measurement techniques in the scientific world.
