Important discovery on dark matter?

is this related to the recent experiments on the hadron collider tunnel at light speed in Europe?
No and yes , the LHC is investigating dark energy /matter on a "microscopic level" , this research was done on a cosmic scale , but they in essence are looking for the same .
Not really. Those experiments relate to quantum physics and why matter exists, by completing the standard model. Dark matter and energy are all about "what is space" and probably time too. We cannot grasp that we might be floating in empty space, so we've been searching for something tangible that would make up space, and possibly also explain gravity; and by extension, understand the boundaries of space and time, even manipulate both if we can manipulate dark energy. But when someone says there is a 99.996% likelihood it exists, I still take it with a grain of salt; if I can draw an example in the computer world, 99.999% uptime still translates to 5 mins of downtime a year; multiply that by billions of years and you still have a huge downtime number - which makes 99.999% in such a large scale still not good enough.
I went today to the open university day of nikhef ,the university in holland of physics research.

They had a speech of someone whos working on a future expiriment in italy at gran sasso ,on dark matter.
The expiriment consists roughly of a drum of XENON gas inside a big watertank deep under the mountains , they think dark matter will intertact sporadicly with the xenongas and they will measure the interaction
The earth has a mass of around a 6 with 24 zeroes kg.
The dark matter which consists inside the volume of the earth is only 0,5 kg , but because its everywhere including in interstellar space it makes up for so much mass in total .
The higgs(or somethinglike it) is there , another update from cern comes at the end of the year.
