Atomic clock 30 seconds off in 20 billion years!:

http://www.physorg.com/news/2012-03-pendulum-ytterbium-clock.html

The old way, which I am familiar with because of my time at Goddard Space Flight Center on the Apollo Timing and tracking system, cesium beam and rubidium beam atomic clocks, now they are going way beyond the microwave signals these atomic beams generate and now are at optical frequencies, at the time of Apollo, the best clock was the hydrogen beam clock, accurate to one second in 6 million years, so this one is three thousand times more accurate than that. The hydrogen clock was about a thousand times more accurate than the cesium beam clocks (made by Hewlett Packard) we used to use.

Time marches on!

It means we can perform experiments about gravity, spacetime, and fundamental constants of science with much more certainty now.

Ah, so you finally admit the universe is billions of years old. About time.

Just make sure you plug it all in correctly, or you might measure nutrinos going faster than light 🙂

Too many mistakes for scientists.

Everyone makes mistakes, scientists included. The beauty of science however is that it is a process designed to discover and correct mistakes.

That is true. I just wish every one would take care to use the process correctly
so they would not make the mistakes to start with. It can cause animosity
when that happens.

It's actually far more complicated and subtle than a 'lose cable'.

Get out of science you religious whackjob.

I have things to say about science too. I am not a one trick pony.

If you simply must respond to the nutter, please don't quote him. I've got him obliterated and quoting him reveals the content. 🙁
