Answer:

new scientific investigations lead to new theories

Explanation:

The investigation into the origin of the universe is a continuous one and new facts or hypothesis keep emerging everyday.

One of the characteristics of scientific theories is that they are subject to changes when new widely tested facts emerge concerning the theory.

Consequently, the existing theories keep getting modified or changed completely as new facts emerge from new scientific investigations.
