Did you know that scientists have revealed the first-ever discovery of a cosmic string? Cosmic strings are like cracks in the universe that formed right after the Big Bang. They are so thin and dense that they can bend light and create double images of distant galaxies. This amazing finding could help us understand the origin and evolution of our cosmos.

Is the Great Attractor a loop of cosmic string?

Recent measurements of galaxy velocities suggest that the observed large-scale streaming1,2 may be attributed to a massive (M ≃ 1016 M⊙) 'attractor' located at a distance D ≃45 h−1 Mpc (ref. 3; h = Hubble's constant in units of 100 km s−1 Mpc−1). We explore the idea that the streaming was induced by a large, moving loop of cosmic string. A stationary loop induces a velocity field that falls off as r−1 where r is the distance from the loop. This is somewhat modified by the motion of the loop, but the r−1 profile still persists in much of the wake of the string. The standard gaussian δ-field (density perturbation) inflationary models of cold or hot dark matter predict, on the other hand, a velocity that should fall off as r−3 away from the density peak. Extension of this model to the Local Supercluster (LSC) allows one to understand its Virgocentric velocity field of r−1.

My year, #1983, puts me in a mixed company of words I wish we didn't need to have, such as #AIDS, #SeasonalAffectiveDisorder, #designerDrugs, deltaHepatitus, #DVORAK (j/k), #nuclearWinter, and #selfHarm.
But also words like #cyberpunk, #betaTest, #freeware, #screenshot, #supercollider, #mousePad, #megapixel, #newb, #cosmicString, #CDROM, #cellPhone and apparently #ringtone and #onesie.
Which words stand out for your year?
