Ask Ethan: Can the Universe ever expand faster than the speed of light?
Ethan Siegel

Hi, I want to thank you very much. Your articles and podcasts make my day. Although I am a total laic, after reading these I always feel as a child who sees the world for the first time. I really wonder how does it feel like to know so much about the universe? Another thing that crossed my mind is, If all we know about the distant universe is from information about the past, do we have a clue what the current state is at all? Thanks
