Details on my ScienceCode

As stated in the earlier post my ScienceCode is:

bb+/un ci0 eu+ dm+/sn de- 
mv/rp sm+ ss- st- lqg+ gr+ 
sr++ gut- fp++/gf  sh0


Here comes my explanation:

I think there was a Big Bang. But I don't know how it came about. There is the idea that the universe has zero total energy, thus making it possible to have been started by a chance quantum fluctuation. The so-called "universe from nothing", although conformal cyclic would be cool: bb+/un. 

I am indifferent about the initial inflation. With "superluminal speed" from Planck length to apple size sounds like a wild theory. Do regions really have to be able to communicate in order to develop the same conditions? (ci0)

I am fine with expansion and have my doubts about the acceleration. Might have been observation bias, so simply: eu+

I am undecided about the source of "dark gravity". I say 50:50 that it is something in our universe, e.g., so far unknown elementary particles. If I had to choose, I'd go with sterile neutrinos for now: dm+/sn

I am not convinced by the popular interpretation of dark energy, especially the part about 70% of the universe, etc. I think this is something else: de-

I am totally pro standard model (full disclosure: I may be biased because I worked on it in my master thesis). I have no problem with (too) many parameters. I don't understand why 19 parameters should be worse than, say, 3. Who can claim with authority that 19 parameters are "too many". Maybe 1000 would be "many" and 19 is already "few". I don't like renormalization, though. A satisfying description should do without. On the other hand, that's a kind of beauty argument. Maybe renormalization is what nature does behind the scenes all the time. On the other hand, physics beyond the Standard Model would be cool. As a science fiction writer, I cannot ignore the fact that "new physics" might offer new solutions. Maybe even small ones like solving the energy problem forever. Anyway: sm+

I don't believe in Supersymmetry. First, that's a lot of theory and necessary particles compared to the added value. Second, none of the supersymmetric partners has been found yet. Until then: ss-

I am critical of String Theory because it is hard to prove. But I see a big hole in other theories that might be filled by String Theory: why does energy clump together into different types of elementary particles. What makes a blob of energy a gluon and another one an electron? String Theory would explain it. But on the other hand, it could be completely wrong, so: st-

I like loop quantum gravity. It is hard to test like string theory. But I could imagine that everything is quantized, including space. Quantization always makes life interesting. Everything we know arises from quantization. A good principle. However, the scale is so small that it is practically irrelevant. That's a pity. I don't know why I like LQG more than ST. It is a bit unfair. I am blank on both. Anyway: lqg+

I think there are many universes, and we happen to live in one that supports life, obviously: mv++/rp

General Relativity nails it. I could (I mean I wish I could) imagine quantum-corrections which make General Relativity an approximation of a more general General Relativity. Incompatibility of General Relativity and Quantum Mechanics is not a practical problem apart from quantum black holes. And if primordial small black holes from the Big Bang are not a thing, then this problem lies 10^40 years in the future until stellar sized black holes evaporate (if they do). General Relativity is good enough for me: gr+

I am afraid that Special Relativity is the final word. On the other hand, 200 years ago everyone knew, that nothing can fly (with fixed wings) if it is heavier than air, right? Logically deduced, undisputed, any defiance a career ending stupidity. Here comes the wing effect. Even fixed wings produce lift. An effect completely unheard of and unthought of until it was invented. The wing effect circumvented a dogma that seemed logical at the time. I am hoping for a similar effect, that we just don't know yet. But I am afraid resistance is futile (and career ending in modern theoretical physics): sr++.

I could imagine that there is no grand unified theory of everything. For sure there is a consistent description of the universe. It may be very simple and emerge from new ways of thinking. But it may be as complex as the universe and not expressible in few symbols on paper. Maybe General Relativity and the Standard Model are independent. Why does it have to be a unified description of all forces? Maybe it's just three forces plus warped spacetime. Two fundamental structures with small modifications so that they work together even in extreme circumstances of Planck lengths and black holes. Modifications so small that we will never test them. Besides, if gravity is not regarded as a fundamental force, then the hierarchy problem disappears: the question why gravity is sooo much weaker than the other forces. The relative strengths of the forces look like: Strong force: 100%, E/M: 1%, weak force: 0.0001%, then nothing for a long time and then gravity with 37 zeroes hiding a very small 1. The first three forces are quite close. Gravity is far off. Much farther than you think because counting zeroes makes it logarithmically. A logarithm of 37 is nonexistent for all practical purposes. Gravity is a totally different beast. Good luck unifying that. The verdict: gut-

I think there are great filters like Rare-Earth and Rare-Intelligence, and we already passed them. In other words, no aliens, at least not in range. Billions of Earth-like planets per Milky Way or not, great filters squeeze the probability really fast. No aliens, too bad. On the other hand: having past the great filter, the universe is ours. Still undecided which great filter really hurts the most. So: fp++/gf

The real world or a very good simulation. It might be a simulation, but for sure not a computer simulation. We are primed to think of "computer" simulations because that's what we learned growing up. Even the real world could be regarded as a simulation run by the multiverse with certain standard model parameters. If it really is a simulation, then in a way we do not (yet?) grok. Like theorizing if God has a beard without being able to grasp the concept of God. Pointless: sh0

All together that makes:

bb+/un ci0 eu+ dm+/sn de- mv/rp sm+ ss- st- lqg+ gr+ sr++ gut- fp++/gf sh0
