Questioning the Big Bang Theory

Click For Summary
SUMMARY

The Big Bang Theory does not assert that the universe was created by an explosion; rather, it describes the universe's expansion and evolution over time. Key points include that the theory indicates the universe becomes smaller and denser as one moves backward in time. Importantly, the Big Bang Theory does not address what preceded the event or what caused it, as there is no evidence or theoretical framework to support such claims.

PREREQUISITES
  • Understanding of cosmology and astrophysics
  • Familiarity with the concepts of universe expansion and density
  • Knowledge of scientific theories and their limitations
  • Basic grasp of observational evidence in science
NEXT STEPS
  • Research the implications of cosmic microwave background radiation on the Big Bang Theory
  • Explore alternative cosmological models, such as the Steady State Theory
  • Study the concept of singularity in relation to the Big Bang
  • Investigate the role of quantum mechanics in the early universe
USEFUL FOR

Students of astrophysics, cosmologists, and anyone interested in the fundamental questions of the universe's origins and the nature of scientific theories.

I am having problem with understanding the concept of big bang theory. Actually I don't believe in the theory. How can we say that this universe was formed because of a big explosion? We can't answer the question what happened before that.
 
Earth sciences news on Phys.org
To the best of my knowledge (which is hardly good but anyway), it doesn't say anything about what happened before happenings could happen. ie, it doesn't claim the universe was formed 'because' of a big explosion.
More like, the first moments of the universe (from what we can observe now) looked like an explosion, localized somewhere.
 
To add to Jerbearrrrr's comment,

Dont think of the big bang as what 'created' the universe. The big bang theory describes how the universe has progressed over time. As we go back in time the theory states the universe gets smaller and more dense. The big bang theory makes absolutely no claim as to what 'created' the universe, what existed 'before' the bang, or what 'caused' the bang. There is no evidence for any of that, so there is no theory for it.
