comment Is there a symbol for “unitless”?
In fact, you could say it's zetta confusing.

@Gugg Whoops. Yotta and Yocto are too easy to mix up.

You should submit this to the "What If?" on XKCD.

comment Could a universe with purely Newtonian mechanics exist?
It is still a philosophical question about physics, though, which is why I put it here.

comment Could a universe with purely Newtonian mechanics exist?
It is somewhat about philosophy, but of a theoretical physical nature, so I put it here rather than Philosophy.

comment Could a universe with purely Newtonian mechanics exist?
It's this sort of theory I was looking for. I understand that we don't actually understand the universe in its entirety, but we understand it enough to know that our simplified, zero-limit approximations of the laws are inaccurate. What I wanted to know is whether a world could exist where they were accurate.

@MartinBeckett There are sleeping bags for two people?

I'm mulling over whether to put a bounty on this question, but I don't have enough reputation for it to be worth it.

The same way that people decided on the original fine-tuning principle, I suppose.

@alancalvitti Specifically, can that fantasyland rigidly adhere to the rules given to it, and still give rise to a stable universe, perhaps one that can give rise to life?

It doesn't necessarily need to be the Universe as we know it. Perhaps different solar systems could arise that supported life.

@alancalvitti I was asking about the entire universe, including things that move at or near the speed of light, and the "big bang" scenario.

Well, it was a great attempt. Thanks anyway.

"You could easily make fine-tuning arguments in a purely Newtonian universe." Yes, but only if such a universe is possible in the first place. My question is, could the fundamental laws of the Universe also have been fine-tuned, not just the constants involved in them?

Adding this tag because it seems appropriate.
