Through extensive data collection and simulation experiments, I discovered this pair of brothers has significant differences. Our Sun is slightly smaller and very stable,
while its twin brother is much larger and unstable. Four billion two hundred million years ago, which is four hundred million years after this pair was born, the twin brother of the Sun exploded,
Note, this is not a supernova as we understand it; the companion star's mass did not reach the conditions for a supernova explosion, like a balloon, it didn't explode directly but leaked air."
Laughter erupted from the audience; this analogy was somewhat amusing to the astronomy students.
"Did you hear that? He started talking about balloons."
"The balloon leaked, a classic from Professor Zhao."
"I really doubt he's even an astronomy major."
"Wasn't someone just saying yesterday? He supposedly sells balloons at the park in his spare time."
