The big bang theory states that the universe began as an extremely hot, dense point in space and has since expanded into the complex structure seen today.
With the aid of a new radio telescope, a scientific team discovers that the universe is actually collapsing, not expanding, into a dense point. Which explains the most likely effect of this discovery on the big bang theory?
A. The new discovery might cause the theory to be dismissed since it contradicts it.
B. The new discovery might cause the theory to be modified since it adds to current knowledge.
C. The new discovery might further support the theory since it presents evidence that corroborates it.
D. The new discovery might further deny the theory since it presents evidence that contradicts it.
