A new celestial wonder has stolen the title of most distant object ever seen in the universe, astronomers report. The new record holder is the galaxy MACS0647-JD, which is about 13.3 billion light-years away. The universe itself is only 13.7 billion years old, so this galaxy’s light has been traveling toward us for almost the whole history of space and time.
During a panel discussion at the SETIcon II conference in Santa Clara, Calif., over the weekend, scientists discussed the Big Bang and whether there was a requirement for some divine power to kick-start the Universe 13.75 billion years ago.
Unsurprisingly, the resounding answer was: No.
"The Big Bang could’ve occurred as a result of just the laws of physics being there," said astrophysicist Alex Filippenko of the University of California, Berkeley. “With the laws of physics, you can get universes.”
