I've heard claims that the Big Bang defies the law of conservation of angular momentum. For example, not all planets spin in the same direction in our solar system. I think venus is an example. How does this defy CAM?
I've heard this claim. It just doesn't make any sense whatsoever. It's completely and utterly incoherent.AdkinsJr said:I've heard claims that the Big Bang defies the law of conservation of angular momentum.

Well, in general, what happens is that if you have a cloud of randomly-moving particles that is collapsing, the total angular momentum will not be zero. But different clouds in different parts of the universe will have very different angular momenta.clamtrox said:Erm, wouldn't you expect things to rotate in different directions if you assume that the initial angular momentum was zero? So you would assume that something fishy was going on if everything rotated in the same direction.

First, the big bang theory really doesn't have much of anything at all to say about the formation of solar systems. The big bang theory is about the behavior of our universe on the largest of scales, beyond a few million light years. A solar system, by contrast, is just light-hours in size (and when we're talking about the parts of it that include Venus and Earth, we're just talking a few light-minutes).
Second, the retrograde rotation of Venus is easily explained by a collision from a large object early in Venus' history.

I don't see how these two statements are in any way related.justwondering said:Since it is considered a fact that NO information could have 'passed' through the initial Big Bang event, it sure is handy that we have the Atomic structure that we do, by pure chance.
Well, yes, this is most likely the case. And many physicists are looking into various possibilities related to this. It is difficult to test such theories, but not necessarily impossible.justwondering said:There may well have been a near infinite number of matter structure possibilities that could have taken place for this particular Big Bang started Universe.

A quick google search shows that this claim is creationist claptrap. They are misconstruing (and I suspect intentionally so) what conservation of angular momentum says. Conservation of angular momentum does not say that the angular momentum of some non-isolated object such as Venus is constant.AdkinsJr said:I've heard claims that the Big Bang defies the law of conservation of angular momentum.

There is no consensus on why Venus rotates the way it does. It is easily explained without a collision.

Angular momentum is a measure of an object's rotational motion. In the context of the Big Bang, it refers to the spinning motion of the expanding universe. As the universe expands, its angular momentum remains constant, which helps to explain the formation of galaxies and other large structures.
According to the theory of the Big Bang, the early universe was a hot, dense state that rapidly expanded. As the universe expanded, its angular momentum caused it to spin faster and flatten out. This led to the formation of the first galaxies and other structures.
Yes, the constant angular momentum of the expanding universe can help explain the distribution of galaxies, as well as the large voids between them. This is known as the "angular momentum problem" and is still an area of active research in cosmology.
Angular momentum is an important component of the Big Bang theory because it helps to explain the formation and structure of the universe. It is also a key factor in understanding the expansion and evolution of the universe over time.
There are ongoing debates and theories about the role of angular momentum in the Big Bang, particularly in relation to the distribution of matter and the formation of large-scale structures. Some theories suggest that the universe's angular momentum may be the result of primordial gravitational waves, while others propose alternative explanations.
