Approaching the Big Bang Debate
When tackling whether the big bang theory completely explains our universe's origins, you'll need to present multiple viewpoints systematically. Start by explaining what the theory actually claims - that the universe expanded from an extremely hot, dense point roughly 13.8 billion years ago.
The theory's strengths are impressive and worth highlighting in your essays. Leading scientists like Hawking and Einstein have supported aspects of this model, and we've got solid evidence backing it up. Red shift observations show galaxies moving away from us, whilst cosmic microwave background radiation provides the "afterglow" of the initial explosion.
However, don't ignore the weaknesses that make some question its completeness. Remember that it's still a working theory - if new evidence emerges, scientists will adapt or even abandon it. History shows us that scientific consensus can shift, and crucially, no human witnesses existed to verify these cosmic events.
Key Tip: Always evaluate whether "completely satisfactory" is too strong a claim, even for well-supported scientific theories.
