Hi, This is Swan. Last day I was replying to a physicist in one of my thread when we suddenly got onto the topic of the galaxy's (and the Universe's,
for that matter) missing mass. As y'all know, we are still wondering why we can detect only 10% of the Universe's mass, and where the heck went the
rest - a whopping 90%. But we do know there's more mass than what we measured; the reason is simply that otherwise, the galaxies would fall apart.
So we searched for this missing mass. At first we accused the neutrino of carrying mass behind our back - neutrinos are nearly undetectable, they go
straight through the Earth without (almost) never interacting with matter; so we thought, maybe neutrinos were carrying this 90% missing mass without
us being able to detect them. But we later discovered that those neutrinos's mass were hilariously too small...
So now one of the theories is that quantum jitter is the holder of this 90% missing mass. It's actually quite clever: according to quantum theory,
particles have a level of uncertainty at the quantum level. That means, they can't have both a defined position and a defined velocity; in order to be
described, we have to consider those particles as "virtual". As a virtual particle can't be directly observed, its position may be virtually anywhere
in space. And, as a virtual particle's level of energy can't be directly observed, this level can virtually get kinda high. This means that what we
see as total vacuum can actually be filled with energy, which would come from these virtual particle's activity. In other words, according to quantum,
even total vacuum hold energy at the quantum level, and this phenomenon is called the "quantum jitter". If you believe in God, you might say this is
his version of space disco dance. I see some folks calling it "dark energy" too. I don't mind, as long as you don't confuse dark energy with dark
matter or dark nebulaes.
Anyway, I was reviewing all this with a friend when suddenly, I realized an important fact: We are in motion! All these galaxies... their stars are
following orbits around their core, some at very high speed.
This is very important: everything which we observe in space is affected by some sort of momentum, of velocity.
That means, part of their rest mass is converted to kinetic energy. This part... gets concealed to our detection.
Imagine that we are watching Galileo, on top of Pisa tower in Italy. He drops, at the exact same time, two different masses, let's say a 70 kg object
(object 1) and a 7 kg object (object 2):
As you know, these two different masses will travel at the same speed once dropped (the reason why object 1 won't drop faster than object 2 is because
object 1 also has 70 kg of resistance to movement instead of only 7 kg). But if you were to be the 70 kg mass as it fell alongside the 7 kg mass, and
were to try and determine the object 2's mass based on its behaviour relative to yours, you could calculate it as (erroneously) the same as yours, as
nothing would prove you otherwise.
As stars orbits around the galaxy's core, their rest mass is converted to kinetic energy, a bit like in our Galileo-drops-two-different-masses
As two stars travel in space alongside, they are following the same principle than the two Galileo's falling objects. Kinetic energy is equal to KE =
1/2 mv^2 . So, as their rest mass is, in a way, concealed to our detection because it is converted, they could be a lot more massive than what we
detected from them... and maybe their actual rest mass could prove to hold the missing mass in our galaxy! This theory (I'll let you guys think of a
name for it) of mine definitively needs investigation. If it could at least explain part of the universe's missing mass, it would still take a bit of
weight (pun intended lol) off the shoulders of Quantum Jitter!
