BA seems to have found a new place to lose luggage...

Lovely shot!

Hello Kevin, Yep, the last one on the write-up is the murky eclipse in the clouds view. The penultimate one is the woman in silhouette and the girls in the deck-chair are, spookily enough, the girls in the deck-chair. I noticed nothing on the policemen in glasses ! That last pic from my own set from...

Lots of mentions of people viewing from Hyde Park in the news afterward. There is a video on ITN's website here and at least one of the photographs on the slideshow available from a link in the upper right hand corner of this report from the Times should be familiar. It was a very enjoyable event.

I helped teach a visual basic course in our evenning classes for the first half of last term, but that's the closest I've come to it. Mostly Fortran and IDL at the moment (unless you count Latex). I think there's a basic handbook round here somewhere though, as the lab's accumulated all kinds of par...

Yep, the 21cm emission is a special one as it is only emitted by hydrogen and only in very, very small amounts (it is known as a forbidden line), which means it gets reabsorbed at very low rates. This allows us to get a translucent picture of the galaxy and with various analyses of what we're seeing...

I've seen the milky way from one of the more light-polluted towns, so any well shielded area should be suitably spectacular (as long as you avoid water pollution - either rising from the lakes and rivers or falling from the skies...)

Yes it's a spoof. Go to the homepage and look through all the pages.

In the scenarios being talked about, something does change to keep the speed of light invariant and that is the frequency of light. Einstein postulated something called the transverse doppler effect whereby the change in 'atomic clock speed' (as it was earlier put) between two frames of reference is...

Replies: 53

Gravity waves are predicted to have very low amplitudes, so some very fine measurements safely away from any other source of vibration are required to detect them. Interferometer experiments like LIGO and the future LISA are thought to be just on the edge of being able to get them, at the moment, GW...

We can detect them through their effects on the space around them, the trouble is conclusively proving that a particular object can only be a blackhole. Normally, within the observational error bars, they are close enough to the blackhole-neutron star boundary to be questioned. What we really need i...

The HST image in that case would remain a piece of evidence that could be scoured historically for other things happening in the field, as well as a piece in the jigsaw of whatever theory took over from dark matter. Analysis may well change, but the observation still has to be fitted in to the expla...

The trouble with that is a singularity is just a geometrical artifact of spacetime, so wouldn't suck spacetime into it. The 'bang' whatever mechanism would cause that, would then put more spacetime into existing spacetime, slowing down the acceleration. As we currently see things, at the moment of t...

Hi cliff, Would that be to do with Einstein's general relativity, the clocks running slower or even quicker than our clocks. I suppose if another galaxy is racing away faster than ours, time would slow down, 2 years to them may be like 10 years to us. i think I'm on the right lines somewhere, time ...
