A bit concerned
The giant sun Betelgeuse which has a diameter of approximately 744,000,000 miles and approaching the end of its short life of several million years and only 640 light years away I am wondering when it supernova which will be clearly seen with the unaided eye, even in daylight, will it cause a mass extension on earth
