The moon most likely used to be part of earth.
The huge large quasar group is the largest known structure in the universe. It contains a grand total of 73 supermassive blackholes and is 4 billion light years across, or about a million million billion (sextillion) miles across, which is four times bigger than anything in the universe should be.
There's actually something even bigger called the Hercules–Corona Borealis Great Wall. It's 10 billion light years across. If the sun were a ping pong ball, this structure would be about a billion miles long.
If two plates are in a vacuum, and they were close to each other, they would eventually be pushed together. Not by gravity, but by the casmir force, which is when virtual particles push on the plates.
Virtual particles pop in and out of existence randomly and are a mystery to science. They may be the cause of the expansion of the universe.
There are thousands of particles flying through you're body every second.
Protons and Neutrons can actually be broken down even farther into quarks. There are 6 different types of qaurks, and protons and nuetrons, which are baryons, have three. That means there could be 216 different types of particles like protons; except they all decay within millionths of a second. Even nuetrons are unstable if they aren't in a nucleus. Protons are the only stable one.
There are 17 particles in the standard model - six quarks which make up protons, six leptons, which include electrons, and five bosons which mediate the various forces.
Particles can act as a particle and a wave at the exact same time.
If you know the exact speed and direction of a particle, then you can't know it's position, and if you know the exact position, you can't know the direction it's moving. It's called the Uncertainty Principle.
What you do now can actually affect the past. If you passed a light through a double slit, and then observed the particle, it effectively has to choose which slit it went through right at the moment you looked, causing it to change the past. (This is badly explained but I dunno how to explain it better)
If you put a cat in a box with a bomb that may or may not go off (it's completely, truly random), until you look, the cat is both dead and alive at the same time. It's called Schrodinger's Cat.
You can send information instantaneously across the entire universe without breaking the speed of the light using quantum entanglement. If two particles are created, as particles are always created in pairs, they're properties always cancel each other out. So if someone were to force one of the particles to change properties, the other one would instantly change too, even if they were infinitely distant from each other.
Special Relativity states that time is different for everyone. There is no past, present, or future because of it. Only what each individual body undergoes as time changes depending on the speed one travels at.
Until we observer particles at the subatomic level, they are just energy with an infinite amount of possibilities, and by looking, we force it to choose a state.
The sun would explode without quantum mechanics since classical mechanics says it would give off an infinite amount of energy.
If you converted all the mass in you into energy, it would be the same as 30 fusion bombs.
