I hear that cats sleep 16 hours in a day on average...

15%+50% = 65%, assuming approx equal distribution of sleep over the cats life, that equates to 15.6 hours a day. Your both saying the same thing

Have you people ever seen such a impatient fool like me?

great minds think alike... We just express differently

[ronthepon]

The total mass in the universe is around 10^55 Kg

Not impressive?

10000000000000000000000000000000000000000000000000 000000 Kg.

Bah... big deal.

[Jay-qu]

+/- a few 100 thousand trillion trillion trillion trillion kg... very large indeed

infact larger than the number of sub-atomic particles that make up all the water on all of earth (~10^48)
!but it is still less than the amount of atoms that make up the planet earth!

A frog's eye can register the light from one photon.
(It takes at least 5 photons to register on photographic emulsions).

We don't know what the frog thinks about this.

Question is: does the frog know what a photon is?

Possibly, I've seen one on a quantum physics textbook.

The Chinese are using wooden spaceships.
The wood works well for re-entry friction/temperatures

Sort of reminds me of this:

When NASA first started sending up astronauts, they quickly discovered that ballpoint pens would not work in zero gravity.
To combat the problem, NASA scientists spent a decade and $12 billion to develop a pen that writes in zero gravity, upside down,
underwater, on almost any surface including glass and at temperatures ranging from below freezing to 300 C.

The Russians used a pencil.

Neptune's moon Triton orbits clockwise while Neptune spins counter-clockwise.
