Is possible that our standard model about universe is wrong if gravity cannot be explained in terms of a particle-based standard model and prediction of quantum mechanics contradicts our common sense? Writer and business owner Franklin Veaux tackled this question on Quora by going into detail about it.

There are actually two different questions here, and they need to be unpacked and answered separately.
First, the surface question: Is it possible the Standard Model is wrong?
No, it is not possible that the Standard Model is wrong, it is certain that the Standard Model is wrong. There are things we observe that the Standard Model does not account for. Therefore, we know for a fact that it is incomplete.
But hold off celebrating, because the second, subtextual question is the one you really seem to care about, and I’m afraid I have some bad news for you.
In your details, you say
If gravity can not explained in term of particle based standard model, and prediction of quantum mechanic about electron behaviour contradict our common sense, it is not the sign that our current standard model of universe susceptible to erroneous
Basically, it appears that the real question you’re asking is “is particle physics wrong because it violates common sense? The things it says make no intuitive sense.”
And that is true. But it’s your “common sense” that is wrong.
Common sense is what tells you the world is flat. The universe is under no obligation to obey common sense. Common sense is nothing but a crude, low-fidelity intuition about the way the world works.
But here’s the thing: your intuition formed in an extremely limited environment of relatively large objects moving quite slowly with respect to each other. Your intuition is absolutely wrong outside that environment.
Particle physics makes no intuitive sense because your intuition is that particles like electrons are little round hard things like tiny marbles that behave like marbles do in the macroscopic world.
They aren’t and they don’t.
Subatomic particles are nothing like macroscopic objects and they don’t behave like macroscopic objects. They are not little round hard balls like marbles only smaller. The Standard Model violates common sense because your intuition does not work at the levels the Standard Model applies to.
Common sense said that no heavier than air machine could ever fly. Common sense said that any person in a carriage going faster than a galloping horse would suffer traumatic injury. Common sense says that the human mind is perfectly rational and always exhibits, um… common sense.
Actually, those are beliefs and not common sense. Common sense is something that most people, regardless of what time period they lived in, would agree is a given. Common sense is certainly not an opinion that some folks had at some point in history.
For example, common sense says that if I stab myself in the arm that it’s going to hurt. Or if I go outside in the winter in Minnesota without a coat I’m going to get cold. Those are common sense.
