4. The vast majority of mass in our universe is invisible, andfor a while,
physicists have been trying reallyhardto understandwhat this elusive
"stuff" is. Assumed to be some kind of particle, there are hopes that
the Large Hadron Collider might produce a dark matter particle or that a
space telescope might detect the obvious gamma-raytelltale signature
of dark matter particles colliding. But so far, hints have been few and far
between; a problem that's forcing theoretical physicists to think up new
ideas.
In a mind-bending2017 op-ed for Nautilus, famed theoretical physicist
Lisa Randall delved into one of the more extreme possibilities for dark
matter. Rather than thinkingof dark matter as one type of particle, might
dark matter be composed of an entire family of particles that create dark
stars, dark galaxies,dark planets and, perhaps,dark life? This dark
universe's chemistrymight be as rich and variedas our "ordinary
chemistry."
But don't go getting excitedabout havinga close encounter with these
"dark aliens"just yet.
The Dark Matter Problem
Our universe is a wonderful, yet confoundingplace.
In the last few decades, we've come to realize that 84.5 percent of the
universe's matter is invisible. Given the rather awkwardmoniker "dark
matter," this stuff exists in a state that doesn't interactwith "ordinary"
matter. Like "dark energy," these things are "dark" because we don't
understandwhat they are.
If there was a lump of dark matter sitting on my desk, I'd have no way of
knowingit was there. In fact, the dark matter lump couldn't "sit" on my
desk at all. It would fall through the desk and floor and down into Earth's
crust, speeding toward the gravitational well at the core of our planet. Or
it might zoom off inexplicablyinto space. Dark matter is so weakly
interactingthat the lump would pass through all ordinarymatter as if it
weren't even there.
5. On small scales, the gravitationaleffect of dark matter is minuscule, but
over cosmological distances,dark matter's presence is most certainlyfelt
— it can be indirectlyobserved from its gravitational influence on
clusters of galaxies and its impact on the spin of galaxies.So we know it's
out there, we just can't see it.
However, we don't know what "it" is, though there are theories.
Ordinarymatter — aka baryonic matter — interacts via the
electromagnetic, gravitational, weakand strong nuclear forces.These
forces transfer energyand provide the structure of all matter. Dark
matter, on the other hand, is usuallyviewedas an amorphous cloud of
"stuff" that cannot interactvia the electromagnetic, weakor strong
forces. It is therefore assumed that dark matter is "nonbaryonic."
(Although there are some theories that hint at a baryonic source of dark
matter — notably MACHOs, or massive compact halo objects. Only the
gravitational effects of nonbaryonic matter can be observed when
enough of the stuff clumps together.
The leadingcandidate in the dark matter search is the aptly named
WIMP, an acronymfor weaklyinteractingmassive particle. As its name
suggests, this hypothetical particle doesn't interactwith normal matter
— it is therefore nonbaryonic.
Establishedcosmological models predict that dark matter — be it WIMPs
or some other form like "axions" — gives our universe structure and is
usuallyoversimplifiedas the "glue" that holds our universe together.
Clumpinglike an expanding3-D web, dark matter influences the
evolution of galaxies.Like beads on a string, these dark matter clumps
gravitationallycorralledordinarymatter into clusters of galaxies with vast
empty voids in between.
Astronomer Vera Rubin, while observingthe spin of galaxies,first noted
that most of the matter in galaxies cannotbe seen. Only a small
percentage is visible as the stars, gas and dust; the rest is held in a large
yet invisible dark matter halo. It's as if our visible galaxy of ordinary
6. matter is merely the hubcapof a massive dark matter wheel that extends
far beyond the bounds of what we can see.
In research publishedby Randall and her team in 2013, a more complex
view of dark matter was exploredand applied to this massive "dark
galaxy" that our visible galaxyis embedded in. In this view, our galaxy's
dark matter halo isn't composed of just one type of amorphous mass of
nonbaryonic matter.
"It seems very odd to assume that all of dark matter is composed of only
one type of particle,"Randall writes in her op-ed. "... an unbiased
scientist shouldn'tassume that dark matter isn't as interestingas
ordinarymatter and necessarilylacks a diversityof matter similar to our
own."
