The laws of physics will be the same. I don't what are getting at with the stuff about the elements. Hyrdogen will be hydrogen, Oxygen oxygen, and if two of the former bond with one of the latter you will have water. One of the interesting theories about life is one of the moons of jupiter, which has vast oceans of liquid methane. Is it possible that life is thriving in these oceans? Could be, would be very different that what we have on earth, and I don't see how we can practically ever find out.

What if there is no hydrogen? What if there are no atoms at all? What if building blocks aren't atoms with a nucleus filled with protons and neutrons and electrons don't orbit in the S,P,D whatever track they are on but matter is some other configuration of some other 'things'? Liquid water is so engrained in us as necessary for life, but what if that is not the case. And, further, what if there is no possible way water could even form as we know it? Would that prevent organisms from being?

I don't know, but getting more into the way they are looking for planets in the 'goldilocks zone' (where liquid water exists) through the Kepler, it made me wonder if it were possible to not be in a goldilocks zone yet still have a place where life could exist.

Or here's a better way to phrase the question....

Is the periodic table a result of the big bang or was it a foregone conclusion prior to that event?

All these worlds are yours except Europa. Attempt no landings there.

We know the universe pretty well, what you are describing would be something very different than anything that could exist in our universe.

While I think that's likely true, it's fun to wonder if there is something fundamental about our universe that we haven't observed yet that makes the speed of light the value it is. If another universe has different characteristics, would the speed of light change and how would that impact all of the things we've figured out about physics in our universe?

Okay, well then, let me ask you this. If it's not possible, within the universe, for matter to exist without consisting of atoms; is it possible for organisms to exist without being of the cellular nature? Or is it more along the lines of atoms:matter::cells:organisms and that must be true?

[jim]

Matter does exist that isn't atoms - quarks, leptons ...



That's the building blocks - the most basic particles in the universe as we understand it today.

As far defining life, I guess that's up to some interpretation. A virus has no cellular structure, but it's not universally accepted that it's not a life form. There is a gray area.

My guess is that other forms would be composed basically as we are - some DNAish elements to it.
