@DungeonMaster, I’ll back up Geoff on the other half of that equation: Presuming to know the age of the universe.
We computed Hubble time in general relativity class and it can be done on the back of an envelope. It’s based on some pretty simple assumptions including approximating everything as homogenous and uniform. This in spite of now knowing the cool universe has some structure.
That said, on that scale not sure how else one would even come close to making an estimate otherwise!
This is where I find it hard to grasp anything physicsy. Especially like the age of the universe. it’s all based on assumptions that are based on our little knowledge and perception.
To my mind we are such a young species, yet we think we know so much.
I don’t think we know that much. Nor do most scientists I know.
Only a best guess based on what we know today. Just enough to get us into trouble. 
Yeah, definitely. We’ll be shouting our mouths off out there and attract unwanted attention.
Or do I just read too much Sci-Fi!? 
If we do it’ll make a great book.

Sept. 5th mind blowing random thought of the day: The last name of the British royal family is Windsor. However, royals who are descended from Queen Elizabeth II through the male line use the hyphenated surname Mountbatten-Windsor. This last name reflects both the surname of the royal family and that of the Queen’s husband, Prince Philip.
