Why stars become bright then dim then bright, etc.

  1. About the argument about particles and such. The particles would make them twinkle because the light has to go through our atmosphere, plus all the junk hanging around there. And you have to remember that light can only travel so far. So the star light is gonna be extremely dim by the time it gets here. Compared to, say, the light it would give a planet in it's solar system.

    Anyways, the reason a planet wouldn't make them twinkle is because it would take longer for the planet to pass the star. It's not going to happen in a split second and make the star twinkle.

    BUT. A planet could still do it. Just not a planet in that stars solar system. So say your star is 100,000 light years away. It's going to look extremely small from earth, right? Now you've got a huge meteor (or planet???) 50,000 light years away. The light from the star is going to be thinning out and looking extremely small from earth.

    So a meteor (or planet) that is 50,000 light years away could easily cross the light path (for a split second) of a star 100,000 light years away.

    Keep in mind it probably won't happen with a planet because planets would most likely block out the light for seconds rather than a fraction of a second that a meteor, not in a planets orbit, would cause.

    I hope someone understands what I'm saying after all that typing lol
