Interacting Galaxies Arp 194 by Hubble Heritage
Amazing
Though a doomed star exploded some 20,000 years ago, its tattered remnants continue racing into space at breakneck speeds—and the Hubble Space Telescope has caught the action.
The nebula, called the Cygnus Loop, forms a bubble-like shape that is about 120 light-years in diameter. The distance to its center is approximately 2,600 light-years. The entire nebula has a width of six full Moons as seen on the sky.
"Hubble is the only way that we can actually watch what's happening at the edge of the bubble with such clarity," said Ravi Sankrit, an astronomer at the Space Telescope Science Institute in Baltimore, Maryland.
"The Hubble images are spectacular when you look at them in detail. They're telling us about the density differences encountered by the supernova shocks as they propagate through space, and the turbulence in the regions behind these shocks."
The Cygnus Loop was discovered in 1784 by William Herschel, using a simple 18-inch reflecting telescope. He could have never imagined that a little over two centuries later we'd have a telescope powerful enough to zoom in on a very tiny slice of the nebula for this spectacular view.

What is physics of the gravitational force
General relativity and
Classics mechanics has their definition on gravitation and formulae accordingly to the context
The Hypothetical theory ...
With the consideration of string theory and models. Gravitation is taken into consideration and account for explanation.
How the gravitation is spread in every dimension.
With theory representing no. of dimensions ( like bosonic, M theory, and others)
Gravitation is spread ....
Speaking of dimensions in 5 6 7 8 9 ... The whole lot of conspiracy theory on gravitation and mystical answers can be solved.
Gravity and the space time tend to behave proportionally.
The gravitational force is formed with 2 bodies with a mass. And therefore the physics of it relies on the 2 mass bodies with the respective constituent and variations that are happening.
For example. Take 2 stars or 2 dwarfs or space time with a considerate light years of galaxy in and around.
And the mass and density with X( Gev) and Y ( Gev), corresponding a gravitational force or imbibing a force in the space time with the formulation perceived with the general theory of relativity and classical mechanics.
From research point of view : the physics of the force may clearly interchange with the mass and density of a celestial bodies which is included and comprised under the space time.
