Why is this radiation so important for these studies, and why can't we use other forms of information (or can we and we just haven't done it yet)? The CMB radiation was emitted a few hundred thousand years after the Big Bang, whereas light can be only a few hundred light years old.

There hasn't been any other form yet because other forms of detections are relatively new. 2) Describe how the Heisenberg Uncertainty Principle and the Anthropic Principle help us to understand the formation of the Universe.
