Is there any evidence that our universe is -not- expanding into another timespace?

The tiny "seed" of the Big Bang must been surrounded by some huge environment that allowed it to expand. Isn't that a more logical explanation than some mysterious "spacetime" that came into being at the moment of the Big Bang?

What was the big blue streak in the sky? Did anyone in SC see it?

It was cloudy tonight when I was on the way home. I just happened to be looking at the sky when I saw a big blue/greenish ball streak right over the car. It only lasted for about 1 and a half seconds and dissapeared- not over the horizon, it just looked like the light was extinguished. It looked like it was right over the clouds- really close. I know there's supposed to be a meteor shower tonight but what I saw doesn't look like any picture of a meteor I've ever seen.
Did anyone else see it? (I live in Lexington, SC) Does anyone know what it could be?
