There isn't really any radically new Big Bang theory; the Big Bang theory has undergone some changes, but many of those are minor.You may want to check the Wikipedia article on the Big Bang for details, as well as on more specific topics such as "cosmic inflation", "baryogenesis", and others.
Or you may want to check YouTube videos on similar topics. I suggest checking the "SciShow Space" channel; their videos are quite accurate.
That's the inflationary theory.
Inflation theory. This theory suggests that in the first moments after the Big Bang, the universe underwent a rapid and exponential expansion, causing it to grow exponentially in size. This concept helps explain certain observations of the universe, such as its large-scale structure and uniformity.

Hello i am minakshi answer is that the big bang theory is an example of old scientific theory as big bang theory explains that there was an explosion but the isotropy and the homogenity of the universe is not explained by big bang theory to explain his we connect inflatation theory with big bang theory to explain it so the big bang theory is also an example of old scientific theory.

Still now the most acceptable theory on the origin of universe has been the big bang theory. you can get more info on big bang theory from wikipedia.
The current prevailing theory is the Big Bang theory, which posits that the universe began as a singularity around 13.8 billion years ago and has been expanding ever since. This theory is supported by various lines of evidence, such as the cosmic microwave background radiation and the observed expansion of the universe.

The Big Bang Theory
I know of no such reference for a "natural" Big Bang Theory. Must be just another way of referring to the Big Bang Theory with a differing focus (i.e. kind of like the Hot Big Bang Theory).
