That implies that we eventually will, which is not what is currently thought, it is believed as I understand it that the observable universe is shrinking, because the rate of separation is rising, so the limit at which the speed of light is lower than the movement away of the expanding bits of universe is moving towards us.

I sort of expect that's all wrong, but I don't have the maths to work out how.
