Meteorite Muddles

Apparently an alleged meteorite killed a person in Tamil Nadu State, India. The following is a photo of the crater.

No one saw this meteorite crater being formed.

When we don’t see it we ‘know’ and when we do see it, or think we have seen it, (and then where is it), it is a landing.

 And then will the meteorite, or whatever it is, also produce a neat circular landing or crater, or are we missing something rather grave?

About Louis Hissink

Retired diamond exploration geologist. I spent my professional life looking for mineral deposits, found some, and also located a number of kimberlites in NSW and Western Australia. Exploration geology is the closest one can get to practicing the scientific method, mineral exploration always being concerned with finding anomalous geophysical or geochemical data, framing a model and explanation for the anomaly and then testing it with drilling or excavation. All scientific theories are ultimately false since they invariably involved explaining something with incomplete extant knowledge. Since no one is omniscient or knows everything, so too scientific theories which are solely limited to existing knowledge. Because the future always yields new data, scientific theories must change to be compatible with the new data. Thus a true scientist is never in love with any particular theory, always knowing that when the facts change, so too must he/she change their minds.
