Is the universe fractal-like, even on large scales? A group of Italian and Russian scientists argue that it displays a fractal pattern on a scale of 100 million light years. Other scientists aren't so sure.
Many cosmologists find fault with their analysis, largely because a fractal matter distribution out to such huge scales undermines the standard model of cosmology. According to the accepted story of cosmic evolution, there simply hasn't been enough time since the big bang nearly 14 billion years ago for gravity to build up such large structures.
Are there many small galaxies, like the one just discovered just outside our own, orbiting the larger visible galaxies?
Three trillion years from now, the universe will be observably static, the Milky Way alone, and scientists of the day likely won't be able to "infer that the beginning involved a Big Bang".
According to the Ussher-Lightfoot Calendar, today is the 6,009th birthday of the universe. Based on James Ussher's interpretation of the Bible, God created "the heaven and the earth" on October 23, 4004 BC. Happy birthday, everything!
Note: I'm doing Mr. Ussher's precise chronology a disservice by fudging the Julian calendar date that he derived with the Gregorian calendar we now use. For that, I apologize.
Maybe the universe is a trillion years old and has experienced several big bangs and big collapses over the years. "People have inferred that time began then, but there really wasn't any reason for that inference. What we are proposing is very radical. It's saying there was time before the big bang."
