Blue Hole
- Researchers found evidence that Taam Ja' Blue Hole is the deepest in the world.

Quarks
- Scientists have reported that the inside of most massive neutron stars is most likely made of quark matter.
- Neutron stars are formed when a massive star runs out of fuel and collapses.
- About Quarks:
- These are elementary particles. Like the electron, they are not made up of any other particles.
- These can’t exist in isolation. They can only be found in clumps (groups) of two or three and such clumps of quarks are called hadrons.
- A quark’s antiquark clump is called a meson.
- These are the ultimate building blocks of visible matter in the universe.
- There are six types of quarks: up, down, top, bottom, strange, and charm.
