Core Drop As previously described, might one drop a 10x10x10 ft cement cube at 15-20 ft from Gulf of Mexico oil/gas conduit. The intent is to seal up such conduit extending down ~1000 ft below sediment surface. The non-compressible fluid collapsing and sealing soft metal casing and compressible gaseous fluid interior. What might be the velocity of such core drop; and might it extend even through the formation? Might this constitute a simulation for ANY core drop, such as for iron inner core of planetesimal hitting proto-earth? Likewise for final core drop of coalescing black holes? Scaling up of mass would not seem relevant for such core drops. Thus might the velocity of core drop be ~700+ mph for say 2 seconds for at 2000 ft water depth?
