Government Health Care and Food Subsidies

"If the government were paying for our health care, the government would have a very strong interest in changing the way people eat." - Michael Pollan

So if the government was subsidizing your health care, they would probably become more interested in healthy food habits and promoting healthy food production rather than subsidizing the corn and cattle industries.
I know, how about making bad food expensive and healthy food inexpensive, instead of the other way around. It's just an idea.

The Center of Black Holes

data:
Approaching the event horizon of a black hole, time slows down.
Upon reaching the event horizon, time stops.
In black holes, matter has collapsed to a zero point; the matter is gone, but the gravitational effect remains.

suppose:
Going beyond the event horizon, time goes backward.
The farther in, the farther back in time you go.
The center of the black hole is the beginning of time: the big bang.
The center of all black holes is the beginning of this universe, or another universe.
What happens to the light that turns back on itself?
Since the gravitational effect of hyper-compressed matter remains in our space, how can the attributes of this mass exist in more than one physical state? Is it 'waiting' to be 'born' as part of a big bang in another universe?
And what about the slow, gradual dissipation of a black hole's mass? How does that effect these ideas?

And by the way, is the gravitational constant really constant? Or does it change over time? Same goes for the speed of light; has it changed since we first measured it?
