<color=brown>"That is very true, Riou. Many early scientists and physicists wanted to learn how the universe got to its present form. So they used telescopes to look deep into space for stellar remnants, background radiation from early celestial bodies. I know it may sound alien to you but, the light traveling from those distant stars traveled for 13.75 billion years before it would reach the Earth. Meaning those telescopes were viewing the universe as it was 13.75 billion years into the past. In a sense, the telescope was like a time machine that could view the past by looking very far away."
