The discussion explores the implications of the universe potentially originating from nothing, questioning whether this means the universe is conceptual rather than physical. Participants argue that if the universe came from nothing, it challenges the definition of "physical entity" and suggests that "nothing" cannot possess properties, thus leading to contradictions. Some contend that the concept of "nothing" is more complex than simply the absence of matter, while others argue that science cannot adequately address the origin of the universe. The conversation highlights the philosophical nature of these inquiries, emphasizing that definitions of "thing" and "matter" are crucial to understanding existence. Ultimately, the debate underscores the complexities and paradoxes inherent in discussing the universe's origins.

I think we can do better. We can simply realize that the question makes no sense, stop asking it and move on to questions that do make sense.


No, he's right...the only "conclusion" is an answer which cannot be contradicted by further questioning...

So, if I have a box with nothing in it*, and I place a box of plumber's putty in it, have I not destroyed the nothing?

You just moved nothing out of the empty box and put in where the box of putty used to be.

No, you're taking an empty box and putting a box of putty inside it..you haven't destroyedd the nothing...It's still there as much as the putty is.

So you're saying that the universe can't come from nothing? That the universe had no beginning?

If so - then the universe has always been. Not for x number of years, but for an infinity of years. Yet here we are as time passes, which implies an incomplete infinity, which brings us back to ... the universe had a beginning and that it came from nothing.

All infinities are not equal, however, and such can be proven mathematically. I am uncertain as to where that leaves the argument, but it seems vaguely pertinent.
