For Windows95,98,2000,NT,Me,XP.
You can simulate a black hole using Einstein's general theory of relativity.
Function
1 Earth
You can set the radius and mass of earth.
2 Sun
You can set the radius and mass of sun.
3 Scroll bar to change a stellar radius(large range)
You can change a stellar radius at the large range.
4 Scroll bar to change a stellar radius(small range)
You can change the stellar radius at the small range.
5 Stellar radius
You can check a stellar radius.(meter)
6 Scroll bar to change a stellar mass(large change)
You can change a stellar mass at the large range.
7 Scroll bar to change a stellar mass(small change)
You can change a stellar mass at the small range.
8 Stellar mass
You can check the stellar mass.(Kilogram)
9 The shoot position of beam of light
You can set a shoot position of beam of light.
10 Stellar density
You can check a stellar density.(gram/cubic centimeters)
11 Schwarzschild radius.
You can check a schwarzschild radius.(meter)
If character's color is gray, a schwarzschild radius does not exist.
If character's color is black, a schwarzschild radius does exist.
This case, a star is black hole.
12 Radius and radius of curvature in the location of stellar radius
You can check a radius and radius of curvature in the location of a stellar radius.(meter)
13 Radius and radius of curvature in the location of 1.5 times stellar radius
You can check a radius and radius of curvature in the location of 1.5 times stellar radius.(meter)
14 Radius and radius of curvature in the location of 2 times stellar radius
You can check a radius and radius of curvature in the location of 2 times stellar radius.(meter)
15 Radius and radius of curvature in the location of 2.5 times stellar radius
You can check a radius and radius of curvature in the location of 2.5 times stellar radius.(meter)
16 Star
Graph of star.
17 Schwarzschild radius
Graph of schwarzschild radius
18 Radius of 1.5 times stellar radius
Graph of radius of 1.5 times stellar radius
19 Radius of 2 times stellar radius
Graph of radius of 2 times stellar radius
20 Radius of 2.5 times stellar radius
Graph of radius of 2.5 times stellar radius
21 Beam of light
Graph of beam of light
22 Launcher of beam of light
You can set position of the launcher of beam of light.
The example of use
Compress the earth.
You can set the earth's radius same as schwarzscild radius.
Then earth will be a black hole.
You can check the radius of earth at this time.
It is only 8mm.
You can check the trace of beam of light that is bent by the black hole.
