Question

which uses more energy , a250 TV set in 1 hour ,or a 1200 W toaster in 10 minutes​

Answer 1

Answer:

The expansion of the universe is the increase in distance between any two given gravitationally unbound parts of the observable universe with time. It is an intrinsic expansion whereby the scale of space itself changes. The universe does not expand "into" anything and does not require space to exist "outside" it.
