is this true???

I also wonder why it is so important for scientists to study about atomic particles colliding in a accelerator. Why do they need to know about quarks? stuff like that? to find good applications to be used in electronics? Are they trying to find better ways to split the atom? to be converted into a doomsday weapon? Scientists are even studying blackholes and are creating miniblackholes in their labs?

One answer is "experimentation". We've had theories about the nature of the subatomic quantum world for a long time - just over a century. But the real test of any theoretical science is the experiment. You never know for sure whether or not the theory is correct until you can run a series of tests to confirm it. Technology had to catch up with theory in order to run real experiments on relativity and quantum physics. As the technology advances, for instance, the ability to have an accelerator that can accelerate particles with energies on the order of 1+ Tev is just arriving.

But they're not trying to find a better way to split an atom. Modern colliders have the ability to accelerate particles far, far beyond the energies needed to split the nucleus of atoms. They're looking for particle "showers" - the particles created when two particles collide at very close to the speed of light. This process is as close as we can get to observing what occurs at the core of a star, a black hole or the Big Bang event. It's basic knowledge they're seeking about the nature of the universe.
