March Photo Challenge - Entries (Post them here).

[Photo Challenge]

The topic this month is: "Gravity."

This thread is only for posting your entry and any comments you'd like to make about your own photo.
If you would like to comment on other entries please use the comments thread.
As usual, one entry per person and the image must be your own work.
Normal forum rules and image size applies.

The image doesn't necessarily have to have been taken this month but we do encourage you to go out and enjoy the challenge.
The winner of the poll, which will be run at the end of the month, will get to choose next month's topic and have their
photo posted in our "Photo Challenge Hall of Fame" thread.

Good luck and good shooting.

350 ton crain lifting one of two Cats to top of 16 stories for demolishing purposes, two Cats so they can help each other get down a floor at a time !
A bobcat was also lifted to push the rubble to the empty Lift Shaft where it fell to ground level where another bobcat collects for tiptrucks

F = G x m1 x m2 / r^2.
G = 6.673×10^-11 N
Mass of the Sun = 1.989 x 10^30 kgs
Mass of the Earth = 5.972 x 10^24 kgs
1 light year = 9.4605284 x 10^15 m
Distance to Alpha Centauri AB = 4.37 ly
Distance to Proxima Centauri = 4.24 ly
Mass of Alpha Centauri A = 110% Mass of the Sun
Mass of Alpha Centauri B = 90.7% Mass of the Sun
Mass of Proxima Centauri = 12.5% Mass of the Sun
Mass of exo-planet Alpha Centauri Bb = 113% Mass of the Earth

The force on the Earth due to the Alpha Centauri system is too difficult for me to calculate, so I got out the kitchen scales instead

Just returned from a wonderful camping trip to Kangaroo Island, South Australia.
(Brilliant dark skies !! )
Took this shot in Kelly Caves, on the South Coast.
An example of Gravity at work, over a large time.
