This seems like a dated postulate. Do you have anything more current that has withstood peer review?

[Rb ver. 2.0]

From your link: “With all of this evidence in support, it does appear that there are about 20 snow comets weighing 20 to 40 tons each that crash into the Earth’s atmosphere every minute. The comets are no danger to life on Earth because they disintegrate in the atmosphere.”

20 per minute x 60 min/hr x 24 hours day = 28,800 per day x 365 = 10,512,000 per year.

That means 10,512,000 20-40 ton snow comets entering the Earth’s atmosphere earth each year magically avoid our orbiting satellites and space craft. Figure in nearly 50 years of space flight and we’ve avoided almost 1/2 billion, 20-40 ton missiles. Damn we’re good.
