What if you could fly through the universe and see dark matter? While the technology for taking such a flight remains under development, the technology for visualizing such a flight has taken a grand leap forward with the completion of the Bolshoi Cosmological Simulation.
After 6 million CPU hours, the world’s seventh fastest supercomputer output many scientific novelties including the above flight simulation. Starting from the relatively smooth dark matter distribution of the early universe discerned from the microwave background and other large sky data sets, the Bolshoi tracked the universe’s evolution to the present epoch shown above, given the standard concordance cosmology. The bright spots in the simulation above are all knots of normally invisible dark matter, many of which contain normal galaxies. Long filaments and clusters of galaxies, all gravitationally dominated by dark matter, become evident.
Statistical comparison between the Bolshoi and current real sky maps of actual galaxies show good agreement. Although the Bolshoi simulation bolsters the existence of dark matter, many questions about our universe remain, including the composition of dark matter, the nature of dark energy, and how the first generation of stars and galaxies formed.

THEY LOOK SO HAPPY
"the sun is our mommy and she is big and very beautiful!"
that was the cutest thing I have ever read
you know girls can tell when you look at their boobs
i don’t care how quickly you glance, 1 second is like 5 seconds in boob time

Human: “HAHAHA Animals are so dumb!”
*goes to war with its own species, uses up all of its resources, destroys its own environment, pollutes its own air and water*
Animal: *licks its own asshole*
human: *licks someone else’s asshole and calls it sex*

This is amazing!
"Cosmos: A Spacetime Odyssey," is a relaunch of Carl Sagan’s classic "Cosmos: A Personal Voyage." The show, hosted by astrophysicist Neil deGrasse Tyson, is designed to reach everyone with its broad, visually stunning approach to science.
Cosmos premieres Sunday (March 9) on FOX, and Monday (March 10) on the National Geographic Channel.
*shouts* ARE YOU READY?
Challenging white supremacy is not racism
Challenging patriarchy is not sexism
Challenging disproportionate distribution of wealth is not classism
CHALLENGING YOUR OPPRESSOR DOES NOT MAKE YOU “JUST AS BAD”
please don’t talk to my friends they’ll probably like you better than me and i’ll just turn into an old colleague of theirs
