isnt there a significant lack of lithium proving the big bang wrong?

1. i don't think you don't know what proof is, or how you would go about proving something wrong
2. the problem with lithum is that the classical big bang theory predicts a certain amount should have been generated, and if you measure how much there is now, we only find 1/4th as much as was predicted. But, remember that prediction is a prediction on how much was created 14 billion years ago, its not a prediction of how much there is now. A lot of stellar nucleo-synthesis has taken place in the last 14 billions years.

It would be like you going over to your friends house who has several small kids, and finding a grocery bag with 5 candy bars in it, and a receipt for 20 candy bars dated a week ago, and then proclaiming: This receipt is bogus!!! There are only 1/4th as many candy bars as the receipt says there should be! (meanwhile ignoring the candy bar wrappers scattered around the room, and the chocolate smears on the kids faces).

1 proof is in the pudding
2 are you implying we have used up 3/4's of the universe's lithium?

no i'm saying the universe is a complicated place, stellar nuclearsynthesis is not fully understood, even the strong force is not totally understood. The fact that the "lithium accounting" does not add up just indicates that the universe is not completely understood, which I don't think comes as a shock to anyone. Maybe the prediction is off, maybe the observations and their estimates are off, maybe there is a totally separate explanation that I can't think of.

What you are saying is like saying: We think George Washington had 20 uniforms, but now we can only account for 3. Therefore George Washington didn't exist. The world is a messy place and it can be very difficult to account for everything billions of years after an event, especially if you don't fully understand the processes that have been happening during those billions of years. This is one of the reasons why it is virtually impossible to prove anything about the real world.

i feel like thats fallacious but i see what you mean. its just hard figuring out where it all came from. what the universe expands into, what was there before it was there, if it has always been there, than are we early in the perception of existing life, or are we primal compared to whats out there. i hate those unanswerable questions damnit. thats why i love science.

The expansion is an internal thing, kind of like blowing up a balloon; it's not an expansion into anything.


The modern big bang theories all incorporate inflation. One of the nice things about this is inflation effectively erases the initial conditions, meaning they are not important to the process. This is nice because it makes doing the calculations much easier and it eliminating many of the fine tuning problems, and several other problems associated with the big bang theory. One of the bad things is that inflation effectively erases the initial conditions, making it impossible to probe beyond that point (to gather information about the universe before the inflationary period).

One of the problems with lithium is that to determine what a star is made out of, the spectral lines of the light coming from a star is checked to see what atom released the light. If you collect enough light you can work out the ratio of the elements present. However, this light always comes from the atoms on the surface of the star. It is assumed that the ratio of elements on the surface is the same as the ratio of elements of the interior; however, this assumption might not be correct. Kind of like licking a candy bar and tasting chocolate, and assuming the entire bar is solid chocolate.

All Evidence points to an intelligent designer ( God ) .

Godastrology: There was light, and then there was a source of light.

OrionGGology, human genome 3.5 billion letters in sequential order, all came by random chance by unguided mindless proccess's and natural select.

Seems legit
