Well, it has been studied and the answer is ...
COSMIC LATTE
Yes, "Cosmic Latte."
Cosmic Latte is the color of the universe, according to a team of astronomers from Johns Hopkins University. In 2001, Karl Glazebrook and Ivan Baldry determined that the color of the universe was a greenish white, but they soon corrected their analysis in "The 2dF Galaxy Redshift Survey: constraints on cosmic star-formation history from the cosmic spectrum", published in 2002. In this paper, they reported that their survey of the color of all light in the universe added up to a slightly beige white. The survey included more than 200,000 galaxies, and measured the spectral range of the light from a large volume of the universe.

I never realized it had a color, would've guessed black though.
I liked number 4., the Earth day is expected to be 55 times longer in 15 billion years.

Apparently the Milky Way tastes like raspberries.

The geological and paleontological record indicates that the number of days in a year is steadily dropping, as the Earth's rate of rotation around it's axis slows. Because of the need to preserve angular momentum in the Earth-Moon system, the Moon is slowly drifting away from the Earth.
Think of the analogy of the ice skater doing a spin. As she draws the mass of her arms inward, she rotates faster. As she extends the mas of her arms she slows the spin.
