Greyness
- You may be looking for the colour Grey or Grey (disambiguation).
According to the Book of Lies, a great empty greyness would fall over the universe in the far future.
As part of his attempt to resolve the Rutan-Sontaran War, the Doctor took Sontar and a Rutan ten thousand years into their future with his TARDIS. He intended to show them that their fighting would end in the destruction of both sides; however, when he turned on the scanner, the display was simply grey. Opening the door confirmed that the universe was a sea of grey nothingness. Sontar described it as "grey mist".
The Doctor tested the greyness with his instruments, but there was nothing for him to interpret: it was completely empty, lacking even the miscellaneous virtual particles, photons, and ions present in the most desolate parts of the universe, and it continued forever. This horrified him. (PROSE: The Infinity Doctors)
There's nothing left. No time, no space, no matter, no energy. The entire universe has gone.
The Doctor theorised that the greyness had been caused either by the Effect or the Time Lords' reaction to it. (PROSE: The Infinity Doctors)
The boy indicated to the Eighth Doctor that Faction Paradox intended to hasten the onset of the greyness. (PROSE: Unnatural History)
