Worked Solution & Example Answer:A quote from a well-known science fiction writer states: "In the beginning there was nothing, which exploded." Using your knowledge of physics, comment on the above statement. - Scottish Highers Physics - Question 5 - 2015
Step 1
Comment on the concept of 'nothing' and 'explosion'
Answer
The statement refers to the idea of 'nothing' that contradicts itself. In physics, 'nothing' implies a state devoid of matter and energy. The idea of an explosion suggests a sudden release of energy, indicating the presence of matter. Therefore, this quote opens a discussion about the nature of existence and the universe's origins.
Step 2
Relate to the Big Bang Theory
Answer
In modern cosmology, the Big Bang Theory posits that the universe began from an extremely hot and dense state and expanded over time. This aligns with the idea of an 'explosion' from a singularity—however, this 'explosion' did not occur in a pre-existing space as we understand it. Instead, space itself was created during this event.
Step 3
Discuss the laws of physics and origins
Answer
In considering physical laws, such as conservation of energy, one must understand that before the Big Bang, conventional physics may not apply. The limits of our understanding challenge our perceptions of 'nothing' and 'explosion,' inviting philosophical considerations regarding the origin of the universe and the role of physics in explaining such phenomena.
