“Clues revealed by the recently sharpened view of the Hubble Space Telescope have allowed astronomers to map the location of invisible “dark matter” in unprecedented detail in two very young galaxy clusters. The team’s results lend credence to the theory that the galaxies we can see form at the densest regions of “cosmic webs” of invisible dark matter, just as froth gathers on top of ocean waves,”
“The clumped structure of dark matter around the cluster galaxies is consistent with the current belief that dark matter particles are “collision-less,” Jee said. Unlike normal matter particles, physicists believe, they do not collide and scatter like billiard balls but rather simply pass through each other.”
PEOPLE HATE SCIENCE CAUSE IT MAKES THEM FEEL SMALL
I ASKED A COMPUTER SCIENTIST FRIEND
WHERE ALL THE EMAILS TO SANTA CLAUS GO,
AND COULD I COLLECT THEM SOMEHOW ELECTRONICALLY,
AS TERRESTRIAL POST OFFICES DO,
FOR ANTHROPOLOGICAL STUDY
AND TAWDRY SENTIMENTAL FAWNING
HE LED ME TO THIS SECTION OF MY COMPUTER
