Millacol88 said:"What occurred before T = 0?" is an interesting one. I think questions like this are more suited to philosophy than physics ;)

Strange thing to say. Where did magic come into it?jadrian said:meh i don't think our universe needed any magic.

It is a very intriguing question what caused the universe to come into being. But there's no way we can expect any evidence that will illuminate it, which is the reason is will likely be a philosophical question for a long, long time.

I writ my reasoning: because there's no expectation of any evidence to be forthcoming of any events preceding the BB.Oldfart said:That seems to me to be a rather pessimistic appraisal, what is your reasoning?

No information from T < 0 will survive the BB. No information = no evidence. We can philosophize, but we can't make any models with any predictive properties. And if it can't be falsified, it's not a theory.
Drakkith said:Physics is a huge area with many different things being researched and discovered all the time. I'm not sure there is an argument like the one you are asking about.
At least I think there are some distressed faces today saying "Why didn't we check if that cable was properly connected?"."And now? How do we cope with this?"
hmmm - to me, it boils down to "what is a field?...[]"
The biggest question in all of physics is often considered to be the search for a unified theory that can explain all physical phenomena, from the smallest subatomic particles to the largest structures in the universe. This theory is often referred to as the "Theory of Everything."
Finding a unified theory is important because it would provide a complete understanding of the fundamental laws of nature and how they govern the behavior of matter and energy. It would also allow for a deeper understanding of the universe and potentially lead to new technological advancements.
While there have been many attempts to find a unified theory, such as string theory and quantum gravity, there is currently no consensus on a single theory that can explain all physical phenomena. However, scientists continue to make progress and advancements in this area of research.
Aside from the search for a unified theory, there are many other big questions in physics, such as the nature of dark matter and dark energy, the origin of the universe, and the possibility of parallel universes. These questions continue to drive scientific research and discovery.
Understanding the fundamental laws of physics can have numerous benefits for society, such as advancements in technology, medicine, and energy production. It can also help us better understand and potentially solve global challenges, such as climate change and sustainable development.
