For instance, if your health plan has an 80/20 co-insurance rate, (coinsurance rates of 70/30 90/10, and flat rates of $5.00 to $20.00 per doctors office visit are also common) your insurance plan pays for 80% of your eligible medical expenses and youre responsible for the remaining 20%. Zip.
The Schwarzschild radius of an object is proportional to the mass. Accordingly, the Sun has a Schwarzschild radius of approximately 3.0 km (1.9 mi), whereas Earth 's is only about 9.0 mm. The observable universe 's mass has a Schwarzschild radius of approximately 13.7 billion light years.
A black hole is that which is surrounded by an event horizon. An event horizon is that which surrounds a region of no escape, i.e. a black hole. In contrast, the mass within its own Schwarzschild radius prescription is of a different and, in a sense, more ambitious nature.or one thing, the overall negative curvature of the universe in these models is inconsistent with the idea of the universe as a black hole. More fundamentally, we need to distinguish between the general notions of an event horizon and the boundary of a black hole.
