'Are there going to be many satellites in space ten years from now?'
Is it appropriate to change this sentence to '...in ten years?' and still mean the same thing?
Sorry, I've got confused. Does the phrase 'ten years form now' mean, for example, this year is 2011, then 'ten years from now' refers to the period of 2011 to 2021?
No, "ten years from now" refers to 2021.
Is there a difference between "in ten years" and "in ten years' time"?
