I wondered earlier after hearing of it regarding the Chinese expedition this morning.

This animation explains it very well, and emphasises just how much of an amazing coincidence the speed of rotation is.

The other amazing space topic this week is the New Horizons Ultima Thule viewing. Spotted by Hubble from 4 billion miles (or is it kms, it's still a long, long, long, long way away...), that must be like spotting a single grain or sand on a beach in Rio with a telescope on a Brighton pier!

...and only a few hundred years ago the Church of Rome was busy burning people that dared to think of what was beyond the confines of earth.

The same effect is also found with Pluto and it's biggest moon I just found out, 4 mins into the video.

The Chinese have a lot of catching up to do as they have only reached the other side of the moon, (I was i there years ago as it happen to be the name of a pub near where I lived).

the Americans reached the edge of the Solar system 6 years ago click here

The universe is a wonderful thing.

I heard recently - on a programme about energy - that the energy radiated from the sun in a single second would meet America's current power requirement for a million years.

The talk was of nuclear fusion, and how much energy was locked up in matter. An expert illustrated the energy potential by saying that the amount of energy a fusion reactor could theoretically produce from a single dollar bill was equivalent to five times the energy released by the Hiroshima bomb.
