I only ask as I was in the garden this evening (just a few moments ago in fact) and I thought I heard something strange but when I turned there was nothing. Heard the same noise again and when I looked closely I could see two bats flying around the garden.

I always thought that human hearing couldn't hear the sounds bats make-or does that just apply to the echo location noises?

I know it seems strange but I definately heard them BEFORE I saw them (I was actually worried it was something smaller and furrier as we live in the countryside).

Thank you in advance for saving my sanity!

Light is fascinating with it particle/wave character, possibly no mass and speed. But if applying energy can speed matter up and can change light's frequency, why can light not be made to go faster?

After the big bang, the stars and other bodies are moving away from each other. As they are moving away from each other, gravitational force by each body on others reduce due to the increase in distance. When the pulling force reduces obviously there should be acceleration. Am I wrong?
