What will Earth be like in 999 trillion years?

 As other answers have said, the Earth will be long gone.

Moreover you’re asking about a time that’s on the order of 100,000 times the current age of the universe. Extrapolating what we know today onward to a future that distant would be like trying to look at a sperm that’s within one hour of conception and use that to visualize how a 10 year old child will look.

Regardless of what various physical theories might predict, we actually know very little about what a time 1,000,000,000,000,000 years in the future would look like.
