Medicare is a federally funded insurance program for eligible participants 65 or over. Medicare has two parts, Part A (Hospital Insurance) and Part B (Medical Insurance). Medicare does not cover 100% of all costs. CDI recommends purchasing a Medicare Supplement Insurance policy if you have traditional Medicare to help offset your health care costs. If you have questions related to Medicare, contact Medicare or your local Department of Aging (HICAP).
7. Temperatures in our universe range from about 3,500,000,000 Kelvin (a supernova) to about 3 Kelvin (space). Our Sun is a class G yellow star and has an average surface temperature of 5,600 Kelvin.
Note that as the energy (mass) increases here, the temperature goes down. For a black hole to form from the collapse of a star, the star must have mass at least about 3 times that of the sun. The mass of the sun is about 2x10^30 kg, so that means such a black hole must have temperature T<2x10^-8 K. So very low.
