Just for fun, let's do a little analysis. I'm referencing the "cricket" video
The video was purportedly taken on Friday last in western Canada. For the sake of argument, I'm assuming that the background depicts the sunset (as
opposed to sunrise). According to this
, sunset on May 21, 2010 in Vancouver, BC occurred at 8:56 PM PDT (Saturday, May 22, 2010 at 03:56:00 UTC). The star-like object in the
upper left would be Venus.
During the video, two "boom" (explosions) can be heard. The first (a soft "little boom") can be heard at mark 0:00: 29:00. The second ("big
boom") can be heard at 0:00: 37:00.
The object displays two events to consider. Event 1 occurs at 0:00:18:00 when the object starts to emit a spiral tail. Event 2 occurs at 0:00:19:00
when the object appears to explode. Notice these two events happen within one second of each other.
Let's assume the two events are the cause of the two "booms". The time between the first event and the "soft boom" is 11 seconds. The speed of
sound is 1,125 ft/s. This would put the object at a distance of 12,375 feet (11s x 1125 ft/s) or approximately 2.34 miles from the observer (camera).
Similarly, the "big boom" is heard 19 seconds after event 2 and thus calculates to a distance of 21,375 ft (4.05 miles).
Since the elapsed time between event 1 and event 2 is one second, the calculated speed of the object during that second would be (21,375 ft - 12,375
ft) / 1 sec = 9,000 ft/sec (1.7 miles/sec = mach 8). Pretty darn fast!
What about the size of the object?
Well, the apparent size of the object at event 1 is very nearly that of Venus. We know Venus has a diameter of 7,520 miles and has a mean distance
from earth of 67,230,000 miles*. For objects of the same apparent size, the ratio of diameter to distance is the same. So, (7520/67230000) =
(x/12375), or x=1.38 ft or about 16.5 inches in diameter.
In the end, we have an object about twice the size of a bowling ball that can travel at eight times the speed of sound. Very interesting … and more
than a little improbable (for any manmade object, that is).
•This is the mean distance. The actual distance varies from 23.7 million to 162 million miles. I wasn't able to find the exact distance of
Venus from Earth at the time of the video. Subsequently, the object size is most probably different than what I calculated.
