back to article Scientists ponder mysterious source of cosmic rays

Scientists are pondering the possible source of an "unexpected surplus of cosmic ray electrons at very high energy", and suggest they're either pouring out of an exotic object relatively close to Earth or represent the fall-out from the annihilation of theoretical particles comprising dark matter. The observation was made by the …

Nothing to do with the LHC

Before conspiracy theories start - they haven't even got up to colliding things yet.

Obviously

It's a huge alien ship that is ready to invade earth. Using some dastardly black hole manipulation as a cloaking device so we can't see it. Also it won't suck us in, as they need something to invade and plunder.

Ah, that old bollocks

Sub-boffin: "Errr, there is something i cannot explain nor have a fucking clue about, what should i do?"

Head-Boffin: "Blame it on Dark Matter"

Sub-boffin: "Yay!"

Conversion

Unless I have got the numbers completely wrong that would make 6148 and a little bit olympic size pools (or 6141 using the reg's converter)

The Sun's Evil Twin

There was a story some time ago about how our solar system ought to have a second star as single star systems are very rare in the universe. It was suggested that during the orbit of this twin (probably a brown dwarf) it had a gravitational effect on the asteroid belt which caused large extinction event asteroids to change their orbit and eventually slam into poor old Gaia. Hence the regularity of extictions (60M Years?) on this planet.

Maybe that is what they've seen.

Where did I put my Cosmology 101 book. . .

Paris because all those nasty particles make a mess of your hair

Darn it! Now that you Earthlings have discovered our secret terra-forming* beam we will have to bring our invasion plans forward by a few millennia.

LHC to blame?

Units

"Yes, we know - that's not a proper standard and we want the figure in Olympic-sized swimming pools."

Volume of Superdome 3,500,000 cubic metres

Volume of minimum size olympic pool 2,500,000 litres. (50x25x2)

So the easy answer is 1400 ossp.

But that is a mimimum size pool. Proper Olympic pools (i.e. pools you actually want to use

for serious competition) are all deeper, typically 3 metres. That gets you to 3,750,000 litres.

The Beijing pool was also 5 meters wider as well as 3 metres deep. Length is clearly not allowed to vary from spec. So it held 5,250,000 litres. But that is an anomoly.

So as a near approximation one Superdome is about 1000 proper olymic pools. Which suggests that far from being an improper unit, a superdome should be added to the lexicon as an accepted alternative to the kilo-pool.

"Near"?

So is this "near", or "near" in cosmological terms - i.e. several hundred parsecs.

Re: LRon was right!

I wonder if it's no coincidence that the CoS have been doing covert adverts on British TV recently (under the guise of "The Way to Happiness").

Anon as I don't want Tom stalking my house for having said something against the CoS.

Evacuate!

I read "the possibility of a very interesting object near our solar system waiting to be studied by other instruments" and immediately thought of an alternative: "the possibility of a very dangerous object near our solar system waiting to wreak havoc on Planet Earth and the solar system in general"

Mine's the silvered one with matching tinfoil hat, "Deep Impact" DVD in the left pocket, and the "Space Shuttle Missions For Dummies" book in the right.

But very possibly high-energy electrons being spewed out by the black hole we've discovered at the heart of the worlds capitalist economic system. Either that or someone has copied and pasted the first three minutes from an episode of STNG into their PhD thesis.

LHC - hardly

Still offline getting expensive repairs and my last understanding is wouldn't be back online until January or so. I guess we'll have to wait until next year for that black hole to consume us.

Naturally.

pedantic tw*t or what

Am i missing something here?

A "pool" of water is a pool of water regardless of how large it is.

And besides even if 1000 pools or so could be put into the 'dome i bet most of them would leak away.

Right?

And what's so super about a dome when all their cities seem to have one.

At least here in Blighty we stopped after realising that the Milleneum Dome wasn't so super after all.

Swimming pools?

"Yes, we know - that's not a proper standard...."

The average mass is 68kg*, and the volume in cubic centimetres is V=453.95 x M **, where M is the mass in pounds (approx 150lb). Thus V = 453.95 * 150 = 68092 cubic centimeters or 0.068092 cubic metres.

Therefore, a balloon of about 850,000 cubic metres*** equates, in proper units of volume, to about 12.5 MSheep.

Those cosmologists....

They seem to have a completely different sense of scale to us.

"An object local to the solar system" = "no more than 3000 LY".

Now given that the nearest other star is about 4 LY away their concept of Local is a bit different to mine. Note to readers: Never send a cosmologist out to the local shops.

Oh, they seem to have taken my coat with them.

Local.. (@Those cosmologists.... )

If next door is 4ly and the local anomoly is 3000ly that is only a ratio of 1:750

Now convert to a scale of say terraced houses and you get 10meter:7.5Km which is probably about right for the 'local' Post Office!

Swimming pools? Superdomes? Pah!

Superdomes? Crazy American abortions of perfectly good Imperial 'standards'.

Everyone knows the true measure of volume for big things is Albert Halls. The trouble with Superdomes is no-one outside of the US knows what a super dome is. It's clearly like their pints, gallons etc, sounds the same looks the same -- totally different size. Olympic Sized Swimming Pools aren't even a ratified ISO standard size!

For the record, 1AH ~= 100,000 cubic metres.

Far more sensible I am sure you will agree!

You may think it a long way to the shops but compared to the universe, that's peanuts.
