This article in The New Yorker about the LHC was very good, and graspable, it is seven pages, so don't miss a one!

My question for the LHC is, are individual protonic energies of 7-14 Tev encountered in natural space-time? Are the individual proton energies in say the Crab Pulsar or Cygnus A's center, greater or much lesser than 7-14 Tev?

Not to confuse 'heat' with 'temperature', the LHC may be hotter than nature, but it will never have more heat.

What are the estimated eV energies in the;

Sun Solar Corona

Sun Solar core

Crab Pulsar

Cygnus A

and lots more; one has a time lapse of daily webcam photos of the 3 year construction of the LHC, like ants building a nest.

TeV cosmic ray events are apparently pretty common, since they've used them to run observations of the Sun's magnetic field, among other things.

LHC results

They are going to discover that quarks don't exist; that what they thought was a single "quark" is really a soup of many, many newly discovered smaller particles. This will lead the scientists to understand that "dark matter" is really "very, very tiny matter".

The most important new questions will be related to their discovery of the nature of different realities of vibrational frequencies. Scientists will prove that the vibrational reality in which humans reside, emanates from a higher vibrational reality. I understand many of you do not understand this yet.

Gravity wouldn't be an issue if you warped the Space/Time instead. :wink:

I guess molecules don't exist because they are just a combination of atoms. Oh, wait! Atoms don't exist because they are made of protons, neutrons and electrons. But those particles don't exist either. As a matter of fact, the universe doesn't exist at all and you aren't reading this.

Dear friends, I am new here and have a question to the great picture of today (sept, 9th). It shows the dwarf galaxy M31, but which is the great galaxy left? Is ist Milky Way or is it Andromeda?? The text doesnot tell explicitly. Thanks for answering, Hans

Sorry my mistake while asking my question. Here is the correct question:

Todays picture shows NGC 205. But which is the huge galaxy above - M31(Andromeda) or Milky way?

Thanks, Hans

It would probably be Andromeda.

BMAONE23, THANKS a lot for these phantastic links! Now it is clear: the huge galaxy in todays foto must be Andromeda. Really great!

<<"The Large Hadron Collider fired its first beam around the machine's full track at 10:28 AM local time (1:36 AM Pacific time).

No actual atoms were smashed today -- that won't start for weeks -- and no results are expected for months, at the earliest. Still, like first light in a telescope, the first beam in the particle accelerator is a landmark moment for a program that has spanned more than 20 years and involved tens of thousands of scientists.">>

<<"Both Fermi and CERN are looking for the Higgs bosun using similar methods of accelerating particle beams to near the speed of light, then colliding them with a force almost as powerful as the Big Bang. Whereas CERN will use high-intensity proton beams, Fermilab's DZero project is using one beam of protons and one beam of anti-protons.">>

Geeze...for something as important as this you can't trust the media. Go to an authoratative source:

http://qntm.org/?board

Or better yet, recognize it with your own eyes:

http://www.cyriak.co.uk/lhc/lhc-webcams.html

Billions of people around the world are still in denial because of the mainstream media, saying things like "but they haven't even started colliding particles yet." Oh yeah smarty-pants? Then how come the IEDAB is reporting the world has been destroyed?

So according to the IEDAB we are all dead... interesting... I had much higher hopes for after-life... I'm still at work. :(

But you know... you can't really trust things with ED in the name... never know whats to be expectED from EDs.

BTW - The quote you list is not mine... sorry I thought that the <<"___">> was an indication of quoting another resource. The quoted sentence actually comes from the link I list below the text. http://www.news.com.au/heraldsun/story/ ... 63,00.html Don't want to be getting crEDit for stuff I didn't say.

THANKS for the funnies! 8)

The God Particle (higgs boson)

The God Particle (higgs boson)

http://ngm.nationalgeographic.com/2008/ ... nteractive

How can you create a particle with 100 to 200 times the mass of a proton by smashing two protons together?

Sorry about the misquote EMC. Interestingly, the IEDAB didn't actually say we're all dead. It just said the earth had been destroyed. Draw you own conclusions. :lol:

Mass-energy equivalence and the fact that matter can "condense" out of high energy environments. The collisions occur at 14 TeV. This is equivalent to about 15000 times the mass of a proton.

The more puzzling question is how can a particle that gives mass to a proton have 100 to 200 times as much mass as the particle? I've heard this explained in a reasonable manner before, but I've forgotten the answer.

No prob

Thanks for clarifying IEDAB's position. Sounds a little bit political though. :wink:

I'm holding with being dead if the earth is destroyed. And still a little disappointed with my outcome.

Until we learn if this fundamental force can be controlled by some artificial means, long-term space travel will remain very difficult to attain. We need to find a way to neutralize the gravitational force around a spacecraft on a planet or moon so it can lift off the surface without so much energy and to create artificial gravity inside the spacecraft for people on long space travels. Otherwise, long space voyages will remain just a pipe dream.
Actually gravity is not what is preventing long term space travel. It's not a huge problem to go into space.

It's the unimaginable huge distances that prevent it the long trips and the energy needed to accelerate to close to light speed, and even at that speed, it is some very long trips.

Artificial gravity on a space ship is not a problem either. It can be created by rotation (centripetal force).

That doesn't really change the existence of quarks. It just changes the definition of a quark or actually just explains what a quark exactly is.

Remember what happened to the space shuttles Challenger and Columbia? Using chemical rockets to leave the Earth and atmospheric braking to return is too dangerous and inefficient. It also takes far too long to get the shuttle ready for the next flight. Better to be able to control gravity to take off and land gently. We can also use gravity control for air travels.

Accelerating to near light speed is not the only problem. Decelerating when reaching your destination is another problem that also requires a lot of energy. Then there is the time dilation problem.

Rotating a spaceship to create artificial gravity also creates all kinds of engineering problems, such as maintaining balance when internal loads shift from one side to another and stopping and restarting the rotation in order to do exterior maintenance during spacewalks. Then you need a non-rotating section for navigation, ingress and egress purposes.
