EDUCATION (Prof. Dr. A. Cuneyt Tas
One day, the
universe was born from vacuum by accident, ejected energy became physical
matters and stars were born by gravitational contraction. O/C/Si were born in
red giant, mixed in supernova and other stars were born again. Planetesimals
circled a star, integrated into planets and their surfaces were melted.
However, some remained without change and trapped the past of our solar system.
4.6 billion years later, a falcon (Hayabusa2) swooped down from the sky,
snatched off the fragments of the past and stuffed them into the capsule. It
passed for one year and separated the spinning capsule breathlessly. The
re-entry capsule shone in the starry night of Woomera, opened a parachute by
accelerometer trigger, was caught in a tree and dropped in. After the long and
winding journey, the samples arrived at last. Please show us, the human beings,
the past of our solar system.
