BUR #50209 is pending approval.
create implication half-life:_blue_shift -> half-life_1
create implication half-life:_opposing_force -> half-life_1
create implication half-life:_decay -> half-life_1
remove implication half-life:_blue_shift -> half-life_(series)
remove implication half-life:_opposing_force -> half-life_(series)
remove implication half-life:_decay -> half-life_(series)
All 3 of these are expansions to Half-Life 1 and should imply it specifically.
