I don’t get the 2nd method. You stated that we have an exact number for how long certain elements take to decay (like Carbon in your example), but isn’t it known that decay depends on the environments (like whether it’s dry or humid)? This can determine whether bones decay over a few years vs over thousands of years according to google. Please explain.

I have a huge problem with relative dating and argon potassium dating. Just because the rock/dirtv s next to the fossil, does not make them the same age. It only means they were deposited in that spot at the same time. The rock was likely formed much earlier

Well no, fossils can only be found in sedimentary rock. Sedimentary rocks are formed by a bunch of layers of sand or other material being stacked on top of each other. The pressure of all these layers compresses the lowers layers and creates stone. So when a dinosaur dies and decomposes and there is left are bones and layers and layers of sand are being laid on top of these bones eventually when the stone is formed the bones will be ingrained in the stone. And there for the fossil and the rocks in or around it will be around the same age.

​@@benjones5799they are wrong, and will not admit they are wrong. They claim agates are formed in a volcanic tube or void, this is not entirely true. Agates are from biological origins. Every agate is biology turned to stone just like petrified wood. And most rocks are also from a biological origin other than volcanic rocks. The rest were once living organisms turned to stone. Even meteors are from biological origins.

There are assumptions in the approach of radioactive dating that need to be admitted and addressed, but we’re not mentioned here. We assume we know the rock’s initial conditions and what percentage has decayed. We assume no outside circumstances that could contaminate any test occurred between the formation of the rocks and our dating. And we assume the rate of decay has remained constant throughout time. We do not know any of these things definitively and we were not there in the beginning or throughout time. How are these assumptions addressed?

I tried my best to figure out if there is any truth for scientists to accurately predict how old fossils are, and I still find it hard to believe if any fossil is millions of years old. To be honest, the scientific process in explaining things that are millions of years old sounds very fishy to me. In 200 years, most things vanish or go out of existence...

The half-life (t₁/₂) of a radioactive isotope can be calculated using the formula: \[ N_t = N_0 \left( \frac{1}{2} ight)^\frac{t}{t_{1/2}} \] Where: - \( N_t \) is the quantity of the substance that still remains after time \( t \), - \( N_0 \) is the initial quantity of the substance, - \( t \) is the elapsed time, and - \( t_{1/2} \) is the half-life. Let's rearrange the formula to solve for \( t_{1/2} \): \[ \left( \frac{1}{2} ight)^\frac{t}{t_{1/2}} = \frac{N_t}{N_0} \] Taking the natural logarithm (ln) of both sides: \[ \frac{t}{t_{1/2}} \cdot \ln\left(\frac{1}{2} ight) = \ln\left(\frac{N_t}{N_0} ight) \] Now, solve for \( t_{1/2} \): \[ t_{1/2} = \frac{t}{\ln\left(\frac{1}{2} ight)} \cdot \ln\left(\frac{N_t}{N_0} ight) \] For potassium-40, with a half-life of about 1.3 billion years, you can plug in the values to calculate the specific time.

5:55 (I'm just curious not judging guys) How you can estimate a bone's age by estimating the age of rock besides it, that rock doesn't belong to the bone sir, and even you suggesting that the particles of rock or bone got under the influence of rock molecules or particals, the outcome or estimation still come for a rock not a bone.🦴

Yes we are assuming the rock layer was undisturbed when it was formed so therefore the fossil is approximately the same age as the rock surrounding it that was dated numerically. It would be the same as your laundry that is next to other clothes in the laundry basket all having been placed there approximately the same time, oldest on bottom and youngest on top.

And we're again on same question mam.
