I am confused by this article. How the hell do they look back in time? Specificly 800 million years ago.
"Using space and ground telescopes, astronomers looked back to when the universe was only 800 million years old and found something that was out of proportion and out of time."
" spotted when the universe was relatively young."
Light takes time to travel. Looking at light that has taken 800 million years, or 12.9 Billion years to get to us, is looking back in time. We can see the Universe as it was, 12.9 billion years ago.
"As astronomers gaze deeper into space, they are looking farther back in time. What Ouchi found was from 12.9 billion years ago. Only three other objects have been seen that are from deeper in time and space."
