i.e something happening out of nothing or was there no birth at all and all that exists today existed since forever?
Chronos said:The bounce scenario is an attractive alternative. It avoids the obvious paradox of the singularity. It creates, however, new problems. I'm unsure these are solvable if physical laws 'morph' with each cycle. Trying to figure out how physics 'works' in this universe is already difficult enough.

TungstenTesla said:Forgive me for being naive, but could someone explain how bounce models avoid the singularity? I thought the singularity was more or less assumed at this point.

John232 said:According to the laws of thermodynamics the universe would have had to always existed. The first law would have to be disproven before anyone could say how energy and matter was created in the Big Bang. I don't think anyone is going to have any luck with that.
Chronos said:That could be a clue something is amiss.
Driftwood1 said:Can you apply the 4 laws of thermodynamics to the initial big bang event? that is to a singularity?
Plebeian said:A random Universe scares me tbh. It could begin anytime and end anytime. The laws of physics could suddenly change and what we know would be of no use.
John232 said:Energy can't be created or destroyed, how could someone apply the laws of thermodynamics to the big bang if energy was created in the process? The first law would have to be shown to be violated in some way before anyone could apply a theory to the big bang that stated that energy was created in the process.
Scientists have observed that the Universe follows the laws of physics, which are based on probabilities and chance. This suggests that the events leading to the birth of the Universe were random and not predetermined.
The Big Bang theory states that the Universe was once in a highly dense and hot state, and then expanded and cooled over time. This rapid expansion and cooling suggests that the Universe's birth was a random event, rather than a deliberate creation.
While there are alternative theories, such as the Steady State theory, that suggest the Universe has always existed and did not have a specific beginning, the majority of scientific evidence currently supports the idea that the Universe's birth was a random event.
This is a philosophical question that has been debated for centuries. From a scientific perspective, the laws of physics and the concept of randomness do not necessarily conflict with the existence of free will in humans. However, this is a complex and ongoing discussion with no definitive answer.
As a scientist, I cannot definitively answer this question as it falls outside the realm of scientific inquiry. While some individuals may believe in a higher power or intelligent design, there is currently no scientific evidence to support this idea. The concept of randomness and the laws of physics provide a more widely accepted explanation for the birth of the Universe.
