Double slit, yes we understand that well. What we think of as a particle actually behaves as a propagating wave. Even heavier objects such as a neutron has wavelength which is used to design some instruments.
Do you have an article or something showing they understand it well? (and who they is) From what I understood, there is still controversy over it. And why the behavior changes while it is being observed or while not (when being observed the particles arrive in 2 rows and the interference pattern disappears).
Dark matter and dark energy - I'm not convinced they exist. They are theorized to fit observations to physics models which don't match observations otherwise. I figure either the observations or the models could be faulty.
Well the scientists who make that claim seem to know enough about it that they can distinguish dark energy to be something different than dark matter.
But if you find a way to create something from nothing, you may have discovered God.
What makes you think all that 'nothing' is really nothin? Long time ago, we as humans used to think the space that exists between 2 people standing in a room was nothing until later we discovered there is actually a lot of oxygen and nitrogen and whatnot else right there in that empty room, detectable with instruments. Just because we don't have means to detect what we perceive as the zero bits in the universe, doesn't mean it is nothing to the observer outside that box.
It is not obvious to me that "spooky action at a distance" is anything other than synchronized clocks. I think someone said it was not, but I didn't follow why not.
I have read that the actual quote from Einstein was,
"I do not believe the Ancient One himself throws the dice."
Well, NIST believes in quantum entanglement:
BOULDER, Colo.—Einstein was wrong about at least one thing: There are, in fact, "spooky actions at a distance," as now proven by researchers at the National

And there are real applications already coming to the world using quantum entanglement like cryptography - Quantum Key Distribution (QKD):
An efficient entanglement-based quantum key distribution is sent from the Micius satellite to two ground observatories 1,120 kilometres apart to establish secure quantum cryptography for the exchange of quantum keys.

The national-security implications of China's interest in space-based quantum communications cuts several ways, posing a threat to U.S. intelligence capabilities but also raising the possibility of U.S.-China cooperation.

Entanglement based protocols:
The quantum states of two (or more) separate objects can become linked together in such a way that they must be described by a combined quantum state, not as individual objects. This is known as
entanglement and means that, for example, performing a measurement on one object affects the other. If an entangled pair of objects is shared between two parties, anyone intercepting either object alters the overall system, revealing the presence of the third party (and the amount of information they have gained).
These two approaches can each be further divided into three families of protocols: discrete variable, continuous variable and distributed phase reference coding. Discrete variable protocols were the first to be invented, and they remain the most widely implemented. The other two families are mainly concerned with overcoming practical limitations of experiments. The two protocols described below both use discrete variable coding.
