No it isnt! It may be how you reacted, but many people were perfectly aware of the fragility of our ball of rock in a hostile solar system. All the discovery of the Yucatan event did was validate that understanding.
Do you have ANY idea of the size of the sun? Even a big comet would make no difference, a mere drop in the ocean. Any solar flare would devour/vaporise a comet before it got close enough to make a drop mark on the surface.
Here is something for you to ponder, at least 1,300,000 earths would fit in the sun. but perhaps a comet the size of Jupiter would make an impression but a comet the size of a comet creating the damage you are so paranoid about is just laughable
More info to educate yourself with, debris is falling into the sun and just about every other object in the solar system all the time. Around 14 million tons of debris from space falls on the earth each year. I cant be bothered with the calculations but it is possible to use that figure to estimate given the surface area and colossal gravity of the sun how much falls into the sun.
As they say, a little knowledge can be dangerous and it is sure that you have little knowledge.
Actually you were the one pretending and what if and maybe, I was simply having a laugh at your expense
You mean you don't think my red rider bb gun,
can't destroy the moon? Gosh Darnit!
