The Large Hadron Collider (LHC) is the world's largest and highest-energy particle collider. It was built by the European Organization for Nuclear Research (CERN) between 1998 and 2008 in collaboration with over 10,000 scientists and hundreds of universities and laboratories, as well as more than 100 countries.
It lies in a tunnel 27 kilometres (17 miles) in circumference and as deep as 175 metres (574 ft) beneath the France–Switzerland border near Geneva.

Carbon Dating
Carbon-14 (14C) is a naturally occurring radioisotope that is created in the atmosphere by cosmic rays. This
is a continuous process, so more 14C is always being created. As a living organism develops, the relative level of 14C in its body is equal to the concentration of 14C in the atmosphere. When an organism dies, it is no longer ingesting 14C, so the ratio will decline. 14C decays to 14N by a process called beta decay; it gives off energy in this slow process.
After approximately 5,730 years, only one-half of the starting concentration of 14C will have been converted
to 14N. The time it takes for half of the original concentration of an isotope to decay to its more stable form
is called its half-life. Because the half-life of 14C is long, it is used to age formerly living objects, such as fossils. Using the ratio of the 14C concentration found in an object to the amount of 14C detected in the atmosphere, the amount of the isotope that has not yet decayed can be determined.

Are we living in flat or round shaped earth ?
As we all have a different mindsets , similarity we believe on different inferences to arrive us at a conclusion that we assume to be true ,possibly in our perspectives .But this would rather leads to different conclusions for specific things , disagreement would follow at last. It's obviously known that we won't go to something better with out agreement.So everyone should have facts that's acceptable every where unlike of myth.
As far as we concerned there's still myth acceptable , specially by uneducated society , although science is what matters and which provides plausible knowledge about our universe.
Are we living in a flat earth or spherical shaped earth ?
Aristotle , a Greek philosopher concerned with these two good arguments for believing that the Earth was a round ball rather than a flat plate. First, he realized that eclipses of the moon were caused by the Earth coming between the sun and the moon. The Earth’s shadow on the moon was always round, which would be true only if the Earth was spherical. If the Earth had been a flat disk, the shadow would have been elongated and elliptical, unless the eclipse always occurred at a time when the sun was directly above the center of the disk.
Second ,Greeks knew from their travels that the Pole Star appeared lower in the sky when viewed in the south than it did in more northerly regions. From the difference in the apparent position of the Pole Star in Egypt and Greece, Aristotle even quoted an estimate that the distance around the Earth was four hundred thousand stadia. It is not known exactly what length a stadium was, but it may have been about two hundred yards. This would make
Aristotle’s estimate about twice the currently accepted figure.
They also have third reason not to believe earth as flat plate. "For why
else does one first see the sails of a ship coming over the horizon and only later
see the hull?"
