The bipolarity of Supernova 1987A and other SNe can be understood in terms of its very early light curve as observed from the CTIO 0.4-m telescope, as well as the IUE FES, and the slightly later speckle observations of the ``Mystery Spot'' by two groups. These observations and the resulting kinematic solution can be understood in terms of pulsar emission from polarization currents induced beyond the pulsar light cylinder by the periodically modulated electromagnetic field, which are thus modulated at up to many times the speed of light (supraluminally induced polarization currents -- SLIP). With plasma available at many times the light cylinder radius, as would be the case for a spinning neutron star formed at the center of its progenitor, pulsed emission is directed close to the rotation axis, eviscerating this progenitor remnant, and continuing for months to years, until very little circumpulsar material remains. There is no reason to suggest that this evisceration mechanism is not universally applicable to all SNe with gaseous remnants remaining, forcing SNe into a geometry consisting of two polar jets and an equatorial torus, of which the former almost never encapsulate 56-Ni positron annihilation gamma rays well, and the latter, in the case of Type Ia SNe, only for those with the largest mass in excess of that lost to core-collapse. A large fraction of Type Ia SNe will therefore lie considerably below the width-luminosity relation as observed, complicating their usefulness as standard candles in cosmological interpretation, and possibly accounting for their apparent anomalous dimming with distance. Pulsar-driven jets from the SNe of the first stars also allow star clusters to form without the need for Dark Matter. SLIP also accounts for GRBs, the Sco X-1 and SS 433 jets, LMXBs, and predicts that GRB afterglows are 100% pulsed at 500/(1+z) Hz.
