CERN operates the Large Hadron Collider (LHC), a particle accelerator that was built to study fundamental subatomic particles and recreate conditions similar to those shortly after the Big Bang. The LHC accelerates beams of hadrons, which are particles composed of quarks, and causes the beams to collide within the 27 kilometer circumference accelerator. Scientists hope these high-energy collisions will help answer questions about the universe and allow observation of what occurred after the Big Bang and what may happen in the future evolution of the universe.

1. CERN’s Large Hadron Collider

2. What is CERN?

3. CERN is European Organization for Nuclear Research

4. CERN studies FUNDAMENTAL PARTICLES – the basic particles

5. What is the Large Hadron Collider?

6. The LARGE HADRON COLLIDER , or the LHC , is a machine built by CERN

7. Its point is to solve some questions about the universe

8. and to re-create the conditions after the BIG BANG

9. Then it will also be possible to see what will happen to the universe later

10. because it is approximately 27 km in circumference. Large Hadron Collider

11. Large Hadron Collider Hadrons are particles made only of QUARKS. *

12. because inside the machine, particles collide. Large Hadron Collider

13. * QUARKS and LEPTONS are FUNDAMENTAL PARTICLES

14. * Protons and neutrons are made up of QUARKS Electrons are types of LEPTONS

15. The first time it was lounged September 2008

16. During the first run, the magnets of the LHC cooled down, and the experiment couldn’t be carried out

17. It took over a year to fix the LHC

18. The next time it was lounged 20 Nov 2009

19. We do not know how long the experiment will last since no one has ever done it before

20. It might last for years

21. How does the LHC work?

22. STEP 1:

23. Electrons are taken away from hydrogen atoms, so that only protons are left

24. OR

25. By accelerating lead vapor, electrons are taken away from lead atoms, so that only the nucleus is left

26. STEP 2:

27. Beams of HADRONS in the LHC are shot in different directions

28. At certain points, beams collide, gaining more speed

29. The maximum speed that the hadrons can reach is 0.999999991 the speed of light

30. Nothing can go faster than light. However, there is no limit to energy

31. Scientists hope to gain so much energy that it will be enough to create a model of the

32. BIG BANG
