  The bipolarity of Supernova 1987A can be understood through its very early
light curve observed from the CTIO 0.4-m telescope and IUE FES, and following
speckle observations of the `Mystery Spot' by two groups. These indicate a
highly directional beam/jet of light/particles, with initial collimation
factors in excess of 10,000 and velocities in excess of 0.95 c, as an impulsive
event of up to 1e-5 solar masses interacting with circumstellar material. These
can be produced by a model proposed in 1972, by Bolotovskii and Ginzburg, which
employs pulsar emission from polarization currents induced/(modulated faster
than c) beyond the pulsar light cylinder by the periodic electromagnetic field
(supraluminally induced polarization currents -- SLIP). SLIP accounts for the
disruption of progenitors in supernova explosions and their anomalous dimming
at cosmological distances, jets from Sco X-1 and SS 433, the lack/presence of
intermittent pulsations from the high/low luminosity low mass X-ray binaries,
long/short gamma-ray bursts and predicts that their afterglows are the pulsed
optical/near infrared emission associated with these pulsars. SLIP may also
account for the TeV e+/e- results from PAMELA and ATIC, the WMAP `Haze'/Fermi
`Bubbles', and the r-process. SLIP jets from SNe of the first stars may allow
galaxies to form without dark matter, and explain the peculiar,
non-gravitational motions observed from pairs of distant galaxies by GALEX.
