Message 806631 - Posted: 10 Sep 2008, 6:41:01 UTC - in response to Message 806630.  

Big surprise the webcast still isn't up. I saw mention of them using evo, but halfway through setting evo up I got too freaked out and stopped. Weird program with many errors on pages and incorrect certificates. Seems a bit strange for a multi billion dollar project to use something so cheap.

It says that you can use either WindowsMedia or FlashPlayer. I use Linux and can see both streams with Mplayer and FlashPlayer. If the stream is bad I shall switch to the BOINC tutorial session in Grenoble. Tomorrow is the start of the BOINC Workshop, with both David Anderson and Bruce Allen speaking.

This is all I could see:
Due to a huge interest for this live video feed of the LHC First Beam day, you may not be able to see the live video stream and we apologise for this.
Please try reloading the page, come back later, or check the other connection options available on this page.
Many thanks for your interest in CERN and the LHC!

If you are in the UK, BBC Radio 4 is doing a whole day of broadcasts from CERN.

http://www.bbc.co.uk/radio4/bigbang/programmes.shtml will take you to the guide.

I think most of this will be webcast too.

Also for those in Western Europe, you may be able to receive Radio 4 on 198 kHz AM Long Wave (1500m).

Thanks, but I 've gone to the BOINC Workshop in Grenoble, where my Linux-Seamonkey-Mplayer-Mplayerplug-in combination works beautifully and allows me to see a tutorial.

The first beam has gone round all 27km:

Working LHC produces first images

Protons have made their first complete lap of the world’s most powerful accelerator to cheers and high fives from assembled physicists.

At 1025 (local time) scientists sent a single beam of protons in a clockwise direction around the full 27 kilometres of the Large Hadron Collider at the CERN laboratory near Geneva, Switzerland.

The journey began at 0930 when LHC project leader Lyn Evans and his team launched protons into the ring. Progress was made in short steps of a few kilometres, so that physicists could learn how to steer the beam...

Now that it is the next morning and not 2am, I have been watching the webcast so it is of course up now. Though by the previous post I may have just gone to bed a few minutes too early.

Good news. The earth is still alive. LOL

Lots of people though, they will create a black hole, and destroy the earth.

Yes, but head-on collisions between clockwise and counterclockwise protons have not yet occurred. So we are safe, for a while. Cheers.

No, Judgment Day was not today, it will be in a couple of weeks.

I'm not worried about a black hole to absorb us, then we all will be gone, no, I'm more worried about eventual strangelings to be created, so maybe life is not what we supposed it to be here on Earth in a few weeks?

Maybe Star Trek won't be fiction then but reality? LOL

I seem to remember reading somewhere that blackholes emit hawking radiation and lose energy as they suck in matter. Not that I'm that concerned by what I read in the sun anyway, but it doesnt sound like tiny black holes pose much of a problem :)

I'm mostly worried about what they haven't thought of as far as escaping reactions. I have to wonder if large scale tests will send out unwanted signals into space that may be perceivable by aliens. Strange thought I know, but you never know.

I think those signals will take a long time to reach other worlds....remember the case of the Phoenix sonde on Mars: it takes about 40 minutes for just one way back to Earth/Mars.
As said before by scientists and physicists, the LHC is boringly the same experiment as Nature has been producing since the beginning of time/Big Bang:
the difference is this time we have more control over it, so we can see what happens, like the different laboratories at CERN and the computer grid system to analyze the results, which, by the way, will take some years from now.
It is also interesting to know that at CERN there´s now the coldest place in the Solar System...the -271 degrees Celsius or 1.5 degrees Kelvin, which is the coldest temperature that can be reached at all;
and the hottest place in the Milky Way Galaxy, with billions of degrees Celsius, far more that the core of our Sun.
All this has been achieved in a controlled way.

Physicists are insatiable for energy. Now that LHC has started, they are already planning a bigger machine, to be built in Russia. See this article on CERN Courier:

It looks like you must have BOINC 5.10.45 to run LHC@home. No 6.x allowed. I learned this from the LHC home page.
Tullio


I don't think this is correct. I downloaded version 6.2.1.4 on 4th August, and had my last WUs between 19-21st August. All went through fine.



Sorry, mis-read my latest version, it should have read 6.2.14.


It looks like they have resolved the issue they had with 6.* BOINC, I now have a LHC WU in my cache, and my BOINC client is 6.2.16.

I guess they are testing before the real thing.

Actually 6.2.18 resolves the issues LHC was having, please upgrade.

Even the upgrade plan is come out for LHC.
the machine will stop a while and run the upgrade operation at 2013 and finish at 2015-2016,from the news,the machine will be more powerful,sensitive and 10xefficiency.

The next generation collider ILC (International Linear Collider) where it going we don't know.

We don't having any capable to product such terrible unknown particle and destroy our solar system.What we capable in near term is send a man to cycle the planet jupiter and back without landing and not such create mini-black-hole or something.
