What's the hottest place in the universe? What's it like inside a
Black Hole? This video climbs the power scales of the universe, from
the coldest and bleakest reaches of our galaxy on out to the hottest
and most violent places known.
How and where do Earth and humanity
fit within the immensely powerful scales that define our universe?

All across the immense reaches of time and space, energy is being
exchanged, transferred, released, in a great cosmic pinball game we
call our universe.
To see how energy stitches the cosmos together, and how we fit
within it, we now journey through the cosmic power scales of the
universe, from atoms nearly frozen to stillness. To Earth's largest
explosions. From stars colliding, exploding, to distant centers of
power so strange, and violent, they challenge our imaginations.
energy is very much on our minds, as we search for ways to
power our civilization and serve the needs of our citizens.
Energy comes from a Greek word for activity or working.
it's simply the property or the state of anything in our universe
that allows it to do work. Whether it's thermal, kinetic,
electro-magnetic, chemical, or gravitational.
The 19th century German scientist Hermann von Helmholtz found that
all forms of energy are equivalent, that one form can be transformed
into any other. The laws of physics say that in a closed system -
such as our universe - energy is conserved.
It may be converted,
concentrated, or dissipated, but it's never lost.
