Clock accurate to 1 second in the lifetime of the universe

I was really surprised to hear that one second in a million years is only just sufficient for the accurate functioning of GPS. But if you think about it light covers a distance of 300,000,000 metres in one second, which would represent a drift of 300 metres a year or nearly a metre a day for the accuracy of GPS.
So in order to maintain positional accuracy to within one metre and a clock accurate to one second in a million years, all the GPS satellites would need to be synchronised once a day.
A clock that can measure time to within 1 second in ~15 billion years represents an accuracy of 2 cm a year. This is is not very much slower than continental drift and is equivalent one wavelength of green light every 3 seconds.
I don't think clocks accurate to 1 second in 15 billion years will be required for day-to-day use like GPS for the time being, but I bet you a pint of frothy nut brown ale that someone will find some use for a clock that accurate some time soon. I wouldn't be surprised if that person is a cosmologist.

Astrology

Astrology predicts the destinations of billions of people around the world according to the positions of the stars and planets, accurately correlated to the time, date and location of their birth. Just as the sun and the moon affect the tides, the planets emit energy fields which synergises with the subquantum harmonics of your chromodynamic fluids. This causes and affects time-reversal in your aural spheres like a dimentially multitemporal mirror.
Through this the future and the past are reflected through the flux of zero point energy fields and when these decohere, your destiny is revealed.

WTC Conspiracy


I'm all for conspiracy theories which is why I don't think they are awfully funny.
But no one looks at the actual science behind them.
Let's take the infamous Word Trade Centre conspiracy theory where the confederalist government brought down the towers with an incendiary mixture of gasoline, paper, explosives, nano-thermite and molten aluminium.
Now I don't want to get into an arguement with anyone here, because I know someone who knows someone who was in New York a couple of months before the fateful day, and that would be disrespectful to them, but its quite obvious to me why the buildings fell down - the answer is in the fenestration of the windows.
If they had windows that opened like french windows or double hung sash windows, then the towers wouldn't have popped like they did. You see the pressure built up inside them from the heat and rising air and simply caused the towers to burst like balloons because the pressure couldn't get out through the double glazed fixed windows, which couldn't be opened to let the pressure out.
So forget about all these pancake demolition theories and think of the science!

Light Extinguishes Fire


Look, you see, if you're trying to light a fire in daylight you can't see the flames as well as you can when it's night.
This explains why it's harder to light a bonfire in the daytime. Also light makes the fire burn with a lot more smoke, so it's always better to turn off the lights and draw the curtains when lighting a fire, because you'll get a much warmer and cleaner burn.
How many times do you find a bonfire that was burning perfectly well the night before, just a pile of smouldering ashes the following day?
That proves that light not only makes fires burn colder and smokier, but also extinguishes them.
This also explains why the light of the flames from a bonfire can cause itself to be extinguished a lot faster...

Green Sky Thinking


Why is the sky blue?
We all know the sky is blue, but why is it blue? Why shouldn't it be green or purple?
After all grass is green and nobody has any problem with that, do they?
And crab's blood is purple... Bet you didn't know that!
