"Neutrino ‘ghost particle’ detected in Antarctica leads to huge achievement in astronomy: DETECTED deep beneath the ice, scientists have traced a particle back to a volatile galaxy in an achievement set to improve our knowledge of fundamental physics" (South Pole) by Nick Whigham (+Nick Whigham +Nick Whigham).

Ghost particles and ice cubes should make for some interesting discussions at cocktail parties.

IN A groundbreaking achievement experts say will usher in a new era of astronomy, scientists were able to trace the origins of a ghostly subatomic particle that travelled nearly 4 billion light-years to Earth.

The incredibly high energy particle, called a neutrino but often referred to as a “ghost particle” because they’re so tiny and difficult to observe, was detected on September 22 last year by the IceCube observatory. The remote facility is located in Antarctica and has giant sensors that sit more than a kilometre beneath the ice of the South Pole.

For scientists, neutrinos can act like messengers from distant cosmic radiation. They travel at nearly the speed of light, can escape the densest environments like black holes and may be traced back to their source of origin.

Despite the fact that trillions stream through your body every second, they have no electric charge and therefore interact rarely with their surroundings making them really hard to find.

The Antarctic facility detected the neutrino during a rare interaction with an atom below the ice. Scientists were able to trace it back to a galaxy with a supermassive, rapidly spinning black hole at its centre, known as a blazar.

Scientists believe that back when the sun was a lot dimmer and Earth was still forming, the blazar spat out neutrinos and gamma rays towards our planet’s southern pole. And now we’ve managed to trace one back.

If i have a triangular structure of three rods of different materials different lengths and different masses. i heat them so that temperature of each increases and they expand to form a different triangle than before.

As there was no external force on this system there shouldn't be a change in position of COM but it does change as the structure changes.

Why so?

Or am i wrong in saying position of COM changes.
(Because i am not able to do the math to prove that the position of COM indeed remains same)
