How does the steady state theory of the universe differ from the Big Bang theory?
A.
The steady state theory proposes that dark matter does not exist; the Big Bang theory proposes that it does.
B.
The steady state theory puts the age of the universe at 4 million years; the Big Bang theory puts it at 5 million.
C.
The "steady state" universe may not have had a beginning; the "Big Bang" universe definitely did.
D.
The steady state theory claims that faster-than-light travel is possible; the Big Bang theory claims it isn't.
C. The "steady state" universe may not have had a beginning; the "Big Bang" universe definitely did.
Well, the steady state theory suggests that the universe has always existed in a state similar to what we observe now, with no beginning or end. It argues that matter is continuously created to replace the expanding universe. On the other hand, the Big Bang theory postulates that the universe began as an incredibly hot and dense point, and has been expanding ever since. So, while the steady state theory has a "no start" policy, the Big Bang theory definitely starts with a bang!
