Captain, dark energy sensor readings show dwarf galaxies orbiting the Milky Way

The dog ate it

Re: DE not DM

It is true that more "normal" (baryonic) matter has been found as technology has improved, people have thought of more things to look for, etc. But there is a limit to how much more there can be without it being visible in some way (either radiating or blocking electromagnetic radiation).

Note that dark energy and dark matter are hypothesized to explain very different phenomena. The only thing they have in common is the word "dark". In the case of dark matter, it is dark because it doesn't interact with light. In the case of dark energy, it is dark because no one knows what it is.

Dark matter is required to explain the unexpected orbital velocities of stars, gas and dust around galaxies (and galaxies in clusters, and gravitational lensing, and ...). The best explanation so far is simply that there is more mass in galaxies than we can see. It is *possible* that this is actually due to something like gravity not working quite as we think. But the more evidence that is gathered, the more likely it seems that it is some form of matter that doesn't interact electromagnetically (like neutrinos; but not neutrinos - for various reasons).

Dark energy is really a placeholder for whatever is behind the apparent (and unexpected) accelerating expansion of the universe. The simplest way of representing this is to plug an extra energy term into the Einstein Field equations (did I say "simple"?); hence the name. But no one really has any idea if it is some form of energy or something else completely. New physics: yay!

DE not DM

This is not about dark *matter*. The galaxies were spotted by a telescope designed to search for evidence related to dark *energy*.

These dwarf galaxies have nothing (directly) to do with either dark matter or dark energy. (And being outside the main disk of the galaxy, they wouldn't affect the rotation curves of the inner stars.)

Re: Hard to get anything done in Japan

I never experienced this in Japan. But the German and the Singaporean companies I worked for were terrible; no one would ever take responsibility for making a decision.

Re: Windows 7?

Thanks. Also found some on Amazon - some of which look very dodgy but some seem to be genuine.

And eBay ... pass me that bargepole, don't worry I'm not going to touch anything with it.

Is it still possible to buy a (kosher) windows 7 license? If so how/where?

Antarctic ice formed at CO2 levels much higher than today's

@Kevin Johnston

No, it is *not* a hypothesis or an assumption. It is based on measured data. It refines/corrects earlier measures but that doesn't mean any of it is just wild speculation.

There is a big difference between "not completely understood" and "we don't know". For most of the things you claim we don't know, we actually have a pretty good idea, within certain error bounds (which may, of course, be large in some cases).

To say it is all opinion or guesses is a little exaggerated.

Single-patent lawsuit hits Apple, Google, Amazon, Priceline...

Thumb Up

Very possibly...

... although, could you do such a thing in 2005? (I'm not really up with mobile technologies)

But I wasn't claiming that the patent was valid or even a good idea. Just that, as always, there is more to these things than even an august journal like El Reg would have you think.

I know that reading patent applications is mind-numbingly dull (you wouldn't want to do it for a living ... oh, hang on ... that's where I went wrong) but I do think the article could have been just a wee bit more specific about what the patent is actually for.

What is claimed

The key bit of the claim seems to be using the IP phone to buy from a merchant "wherein [the] user's contact and payment information is not transmitted to [the] merchants [but this] information is available to [the] merchants" (legalese stripped for readability)

So much narrower than "its a smartphone".

ASSANGE ARRESTED in London - in court later today

Is Assange some fighter for freedom and protector of democracy?

No, he is doing it to make money and to promote his own ego.

Robin Hood?

Or twat?

Just because he is some sort of folk hero to a few people doesn't mean that the judicial system should let him go. If he is innocent then let him prove it in court. I though he was all in favor of open processes, not running away and hiding.

At least they have given up the *pretence* of taking scientific advice.

Not forgetting, of course, that Chinses is a family of related (but mostly mutually-incomprehensible) languages, rather than a single language. Mind you, English may be going the same way in all its different incarnations around the world.

Much of recent global warming actually caused by Sun

A new low in reporting

A slightly more accurate summary can be found here:


"The effect is slight, but it could call into question our understanding of the sun's subtle effects on climate. Or could it? ..."

Note: "the effect is slight" - warming by about 0.05 °C in the current minimum - rather than "much .. actually caused by sun".

Not spin

Fair comment

I was struggling for a moment to see the point of the web apps if the company is already completely Windows/Office based. But you make a good point about centralization and control.

I am working at an engineering company where SharePoint is widely used but all the developers are mainly Linux based. So, nah!

Mystic Met closed Europe with computer model

Er, no.

CLimate models are _very_ different from weather models. This would have been based on weather models.

And, guess what, you _can't_ see the ash - even if you fly through it. Neither can the planes' radar. Which is why it is so (potentially) danberous.

You made them up.

What is "proper" forecasting then? Looking at a bit of damp seaweed? Asking gran if her joints ache?

Oh looking at weather stations: that would tell you what the weather _is_, not what it is _going_ to be; did you miss the "forecasting" bit?

BBC: Ash plane 'finds a lot of muck' in UK airspace

I assume this is part of El Reg's attempt to discredit the Met Office and anyone else involved in climate change and, although the BBC are part of the conspiracy too, I thought this was interesting...


"A high-tech plane with sensors calibrated to find volcanic ash has landed after finding 'a lot of muck' in UK airspace.

Aeronautical engineer Dr Guy Gratton of Airborne Atmospheric Measurements, said he would advise against flying passenger jets in those conditions. "
