Well, there's time and geometry, two of A-G's favorite things. And, I read of a particle, detectable though it has no mass. It seems to me that there is much more than 'one more thing' that we, in reality, don't know.
But, it's not enough to simply say that we don't know everything, therefore anything is possible, even if it is true that definitive judgements are not possible about systems of which we know little. I don't know where some people get the idea that the fact that we don't know everything is used as an excuse not to look. I think maybe that accusation is more a hope than a thought.
"Is that why a Unified Theory has proven to be so difficult."
Is that what has the Masters of the Universe nervous? What might be found among the so-called hidden dimensions as the result of an attempt to integrate what we know with what we might find out? Permit no connections until it's certain there will be no uncontrolled, or 'surprise' consequence? Who cares what the consequences are; let the chips fall where they may. Do you know something here? or are you simply speculating? (no offense intended).
"Long ago in a far and distant planet in a far and distant galaxy far far away."
And once upon a time.
In the absence of time, there can be no event. In the absence of space, there can be no thing. Without space/time, there is no causality.
Thus space/time is more fundamental to physical reality than energy/matter.
So if the question turns on 'one more thing' then the answer is dimensional (either spatial or temporal).
YHAOS, You are asking some interesting questions. That does not mean there is always an answer for those questions.
When I state ""What if there is, in reality, one more thing?", I am referring to the Conservation OF Mass and Energy. That Law states there is only mass and Energy in the Universe.
Do you agree with that? Do you have any indication there is at least one more thing besides Mass or Energy?
Mass and Energy exist in Space/Time.
Without Time there is no movement.
With movement there must be Space to move in.
Mass is solid Energy.
Are you able to define Energy without a comparision, or without stating what it does. Just saying what it is.
In my humble opinion, using comparisons, with my small amount of insight into Energy I am aware there is something there we don't know how to measure, or test.
There is no need to go into all that here, but when one just deals with examining simple questions about life on this planet and in this Universe we immediately observe the untold beauty and complexity upon complexity in the smallest particle of anything. Our DNA is just made of Mass and Energy??? Then how is it that such a massive amount of Information is contained in those spirals.
I hope I am making myself clear.
I am not running from any questions. I am amazed how we can so easily leave out one major cause and then make Laws and Theories as if we know what we are talking about. Then within five years we can say , Wait a minute . We need to redesign our Theories and one of our Laws.
Here is what I do believe.
With God all things are possible.
With out God No thing.
It appears to me that what we call Science is very often an effort to explain "reality" with no mention of a Creator.
Just look at the inner ear of a child. That was no accident.
You see I have been using Mechanical objects for years. It is obvious to me that the inventors of many things have used the actions and abilities of the Human body to design there mechanical instruments.
Who designed the human body??? An Accident of mutation????
Really???
