Expected Result:
The user should be redirected to the documentation page.

Actual Result:
An error occurs and the documentation page is not visible: 404 HTTP status code "Page is not found" is displayed.

An implementation has been written using a normal Python rather than Numpy, therefore it is too slower,because Python is slow language. If the implementation will be rewritten applying the power of Nympy, this will give a significant result related to performance.

When I install this module, several modules (ex) numba) are not installed.
I think you should make setup file by setuptools module

When I installed the package from pip, 2 dependancies were not installed, numba and pandas specifically. It's not big deal, but might be nice to just list them as dependancies.

in examples/2000body.py:

field.generate_random(3500,mass=[100,500],r = [-40,40])

in gravity_simulation/gravity.py:

def generate_random(self, N_bodies, mass=[20, 500], r_x=[-5, 5], r_y=[-5, 5], r_0=0, velocity=[-5, 5], alpha=[0, 360]):

So running this example causes unrecognized argument error

Thanks!
I just needed to write this thank you word, this is super helpful.

On the object Body, the math operators should be overridden, which will bring the reducing the quantity of code and quality will be better. Also in this way will open the more possibility for implemented of Numpy
