I have always thought that the only thing that can enter into earth's atmosphere

[Maraya1969]

is the Sun's rays. Am I right?

I've had discussions with my right wing crazy climate denier brother and I wonder if he thinks that the universe is sending us clean air all the time!!!!


But I don't want to come out with that argument unless I am sure I am right.

1. there is shit from space raining down on us all the time

dust, rocks, metal, etc

3. I'm sure we aren't getting fresh air from some cosmic ventilation system though

2. I think the dinosaurs might have had a different opinion

however briefly they may have held it.

4. +100 Yup, we routinely experience space rocks and even satellite debris raining down on us.

It's all due to the gravity of our situation!

5. It's really a fairly massive problem, when you get right down to it.

7. About 100 tonnes a day of space debris, mostly dust

Let's start with natural stuff. The US National Research Council (NRC) has released the riveting Defending Planet Earth: Near-Earth Object Surveys and Hazard Mitigation Strategies, which tells us that around 100 tonnes of "very small objects", mainly dust, drops on Earth every day. There is no recent record of anyone killed by bigger bits, although a few cars in the US have been damaged this century and one, the famous Peekskill meteorite car, has toured the world.

Not clean air, unfortunately.

8. Thanks for this. 100 tons could explain why my house always gets so dusty.
