.I was wondering if anyone in the know on this site had any knoweledge of some strange things happening there. Like odd trips planned for the Pope, any attempts to begin storing away some of the valuable Vatican artifacts.
it would be total caos if it was actually gonna hit... but then again i dont think everyone would believe unless the government said so..
is there anyway to survive this.......
Anyone who lives near Greensboro NC U2U me if you are interested in helping me and a couple of friends surviving this, if it happens...
Impact Effects
Robert Marcus, H. Jay Melosh, and Gareth Collins
Your Inputs:
Distance from Impact: 1000.00 km = 621.00 miles
Projectile Diameter: 1818.55 m = 5964.86 ft = 1.13 miles
Projectile Density: 38 kg/m3
Impact Velocity: 222000.00 km/s = 137862.00 miles/s
Impact Angle: 30 degrees
Target Density: 1000 kg/m3
Target Type: Competent Rock or saturated soil
Energy:
2.95 x 1027 Joules = 7.04 x 1011 MegaTons TNT
The average interval between impacts of this size somewhere on Earth is 1.5 x 1011years
Crater Size:
What does this mean?
Transient Crater Diameter: 307.69 km = 191.08 miles
Final Crater Diameter: 651.76 km = 404.74 miles
The crater formed is a complex crater.
Thermal Radiation:
What does this mean?
Time for maximum radiation: 0.01 seconds after impact
Visible fireball radius: 2789.6 km = 1732.4 miles
The fireball appears 634.0 times larger than the sun
Thermal Exposure: 1.36 x 1011 Joules/m2
Duration of Irradiation: 3727 seconds
Radiant flux (relative to the sun): 36462.8
Effects of Thermal Radiation:
Clothing ignites
Much of the body suffers third degree burns
Newspaper ignites
Plywood flames
Deciduous trees ignite
Grass ignites
Seismic Effects:
What does this mean?
The major seismic shaking will arrive at approximately 200.0 seconds.
Richter Scale Magnitude: 12.5 (This is greater than any earthquake in recorded history)
Mercalli Scale Intensity at a distance of 1000 km:
IX. General panic. Masonry D destroyed; masonry C heavily damaged, sometimes with complete collapse; masonry B seriously damaged. (General damage to foundations) Frame structures, if not bolted, shifted off foundations. Frames racked. Serious damage to reservoirs. Underground pipes broken. Conspicuous cracks in ground. In alluviated areas sand and mud ejected, earthquake fountains, sand craters.
X. Most masonry and frame structures destroyed with their foundations. Some well-built wooden structures and bridges destroyed. Serious damage to dams, dikes, embankments. Large landslides. Water thrown on banks of canals, rivers, lakes, etc. Sand and mud shifted horizontally on beaches and flat land. Rails bent slightly.
Masonry B. Good workmanship and mortar; reinforced, but not designed in detail to resist lateral forces.
Masonry C. Ordinary workmanship and mortar; no extreme weaknesses like failing to tie in at corners, but neither reinforced nor designed against horizontal forces.
Masonry D. Weak materials, such as adobe; poor mortar; low standards of workmanship; weak horizontally.
Ejecta:
What does this mean?
The ejecta will arrive approximately 494.4 seconds after the impact.
Average Ejecta Thickness: 93.4 m = 306.32 ft
Mean Fragment Diameter: 1.0 cm = 0.41 inches
Air Blast:
What does this mean?
The air blast will arrive at approximately 3333.3 seconds.
Peak Overpressure: 25503062.5 Pa = 255.0306 bars = 3621.4349 psi
Max wind velocity: 3687.8 m/s = 8249.5 mph
Sound Intensity: 148 dB (Dangerously Loud)
Damage Description:
Multistory wall-bearing buildings will collapse.
Wood frame buildings will almost completely collapse.
Multistory steel-framed office-type buildings will suffer extreme frame distortion, incipient collapse.
Highway truss bridges will collapse.
Highway girder bridges will collapse.
Glass windows will shatter.
Cars and trucks will be largely displaced and grossly distorted and will require rebuilding before use.
Up to 90 percent of trees blown down; remainder stripped of branches and leaves.

Click here for a pdf document that details the observations, assumptions, and equations upon which this program is based. It describes our approach to quantifying the important impact processes that might affect the people, buildings, and landscape in the vicinity of an impact event and discusses the uncertainty in our predictions. The processes included are: atmospheric entry, impact crater formation, fireball expansion and thermal radiation, ejecta deposition, seismic shaking, and the propogation of the atmospheric blast wave.

I can't believe that there's actually 20 pages on this topic. Who would have thought? Take the points and run man.

SO I researched the pictures and found that there is indeed a gap of like 20 hours, but why the question of video editing and tampering as previously mentioned? The comet just looks to be further along than before.
I tried to post the pics, but couldn't do it, so here're the links for you
