If the universe is expanding at a rate of 68km/s then how is it possible to leave earth without earth leaving you?
Wouldn t it be like throwing a bottle out of a moving vehicle? I mean to say, if we left earth in a rocket how would it be possible to catch up with earth again if it and the entire solar system is literally flying away. I m not a physicist so I have no idea if this is a dumb question or not. Be gentle.
