>Two separate teams of researchers have found half of the universe's hidden matter, partially solving a mystery that has long troubled astronomers.
>The matter is made up of particles called baryons, heavy subatomic particles made up of three quarks.
>Astronomers discovered the missing baryons among strands of hot, diffuse gas linking the universe's galaxies together
How will physicists even recover?

What are dark matter and dark energy?

I read the wikipedia article but didn't understand.

Does is freak anyone else out that 80 percent of the universe's mass comes from a substance we can't explain or observe? Dark matter doesn't emit light or energy, yet it is rapidly growing through our universe and without it we wouldn't exist. The fact that we may never understand our own universe baffles me. We are the kin to this universe and deserve to know more.

What are some of /sci/'s theories as to what dark matter is and why we need it?

Does it exist? Is it the scientific equivalent of God?
>Solves a lot of astronomical/existential problems
>Can't be detected by modern science
>Permeates all of everything.

Also, what does their presence mean for theories like heat death of the universe?

Also isn't heat death a misnomer since the universe itself doesn't really go anywhere? It's too cold for life, yes, but all the matter would still be around.

>What if there was a theory that explains the observed universe without dark matter?
>A Chinese astronomer from the University of St Andrews has fine-tuned Einstein's groundbreaking theory of gravity, creating a 'simple' theory which could solve a dark mystery that has baffled astrophysicists for three-quarters of a century.
Dark matter is officially a defunct concept by """"""""""physicists"""""""""" who couldn't think outside of the box

What does /sci/ think of this?
