What we had just studied are the major intellectual revolutions in the past. at present, what are the widely acceptable theory that could explain? need help for this guys​

I'll try to help as much as I can, however this is under the Spanish topic so erm.. I'll give you my answer in spanish and english I guess. Very sorry if this wasn't helpful at all!

English: There are a few theories that you start off with. Some simple ones are the Big Bang theories, or the theory of evolution by Darwin is another one. Celestial mechanics may be a good topic to use, and the Endless Void or Big Crunch theory. These theories have already been thought of, and you may use your own ideas to add onto theirs. This question may need research and facts that you may have to find on your own. This topic isn't really my strong suit nor have I ever heard about this question.

Spanish: Hay algunas teorías con las que empiezas. Algunas simples son las teorías del Big Bang, o la teoría de la evolución de Darwin es otra. La mecánica celestial puede ser un buen tema para usar, y la teoría endless void o big crunch. Estas teorías ya han sido pensadas, y puedes usar tus propias ideas para agregarlas a las suyas. Esta pregunta puede necesitar investigación y hechos que usted puede tener que encontrar por su cuenta. Este tema no es realmente mi fuerte ni he oído hablar de esta pregunta.

I hope this was helpful at all and may have started ideas! Sorry if I understood the question you were asking wrong.
