Question

Which of these is the most likely reason why the Steady State Theory of origin of the universe has been rejected?

it was too old to be used in modern times

it was too complicated for scientists to understand

scientists found new evidence to prove it invalid

scientists discovered a shorter theory to replace it

Answer 1

The Steady State theory was discredited when scientists found that it did not follow all the rules of physics. The Big Bang theory was further supported by the discovery of the temperature of the universe.

Therefore the answer that makes most sense is:

scientists found new evidence to prove it invalid

Answer 2

The correct answer is scientists found new evidence to prove it invalid

Steady state was very popular, especially in the 20th century, but it was proven to be invalid when more evidence about the universes age was found. The evidence was mostly observational so it was easy to prove it to be incorrect.
