Temperature in the center of a black hole

To most of us a black hole means are an infinite gravitation pull. Light travels a distance of a 186 thousand miles in a second or just under the equivalent of 300 thousand km. If we do the math's on this, everybody I've talked to agrees gravity slows light it has to be a variable speed but only up to a maximum speed limit. If do our math's projects a distance of 669 million 600 thousand miles by the time a TV program ( 669,600,000mph ) or just under 10 thousand and 80 million kilometers. ( 10,080,000,000kmph ).Black holes captures light speed and every below. There is no reason why not there is a escape velocity above light speed.  .

If we do some more math's we realize mathematics projects since there is no resistance in any vacuum light must have an infinite velocity. The fact is, despite no resistance light doesn't go any faster. If we do the math's considering gravity slows light the maximum speed limit we'd think has to be a reflection of the entire gravity of the universe keeping light at that constant velocity.

The math's of recent cosmological research the amount of gravity doesn't seem to add up holding the universe together. It is supposed to take mass for gravity exist. There doesn't seem to be enough visible mass to go round.

If we do more thinking we'd think the infinite gravitational pull of a black hole would the ideal source holding the universe together from expanding even stop light speed velocity completely.

Theretically everything shouldn't exist including temperature. If a black hole is really infinite ss we think should be infinitely cold in a black hole. In theory a litter of steam should freeze well past freezing, minus 273 thousand trillion digress Celsius in less than a second.

The fact is winter time temperatures on earth at minus 50 kills everthing it touches in less than seconds let alone minus 273.This figure is the absolute coldest temperature possible. It is a point all atomic activity in matter ceases.

Yet math says there is no reason why can add successive naughts to  it, minus  2 thousand 730 degrees,  minus  27 thousand 300 or minus 273 thousand or way below minus 273 thousand trillion degrees nowhere near infinite coldness. In other words minus 273 degrees is the coldest limit where atomic behavior ceases.  Activity can't get any colder. In other words if this can be applied including if velocity faster than ligh can escape to black they should be finite.
