Scientists have had a hard time explaining how any global darkness from debris clouds after such an impact could have lasted long enough to cause the widespread extinctions.

The site was deliberately detonated to shift the Moon from a collision course with Tora, a proto-planet still forming in the centre of a debris cloud.

An engineer in Texas came up with the idea of deliberately crash ing the Lunar Prospector and ob serving the debris cloud to determine whether there is water on the moon.

The vulnerability of satellites to debris and the possibility of attacking LEO satellites to create debris clouds, has triggered speculation that it is possible for countries unable to make a precision attack.

The Geminid shower has been observed for about 150 years, but because the debris cloud is gradually changing position, there will come a time when its orbit no longer intersects with Earth's.
16.
The disintegration of the planetesimal generates a debris cloud which passes in front of the star every 4.5 hours, causing a 5-minute-long fade in the star's optical brightness.

They ll be here in a thousand years .'A few weeks later, from that same street, I watched them crumble and was running with a thousand screaming people away from a debris cloud rapidly chasing us.

"In our model, when the parent body explodes, it puts a debris cloud around every fragment, " said Dr . Thomas Van Flandern, publisher of the journal Meta Research, who developed the theory.

Simply put, a single missile could deliver a volley of three to twelve warheads to the target where they could each detonate at approximately the same time, thus dispensing with the disruptive debris cloud that Dense Pack relies upon for protection.
20.
Every other warhead targeted on that missile field would have to travel through that debris cloud to reach its target, and it was theorized that the act of traveling through that debris cloud would " trash " the warhead before it could detonate.
