Revisioner SBA deployment instructions

Before reading this documents, you should be acknowledged that the deployment process should only be done by people that have sufficient knowledge in the Information and Communication Technology. Stupidly deploying this program in an unproper way can results in breaking your computer or even more. You are also told that the author of this deployment guide cannot be hold liable for any contents in this guide and the corresponding app as well, use it at your own risk!


If you find difficulties in deploying this application or you want to view the working demo, feel free to contact me via email My github username is michaellee8.


  1. You will proably need sudo access or admistrator access to perform the below actions.
  2. Running the app server requires internet connection that can at least connect to the npm repo and google firebase, and the server have to be accessible from internet with proper internet setting like firewalls so that the firebase auth server ha

# Theoretical Proposal of Gravitational Circular Transport System
## Inspiration
In the recent discuss with Professor Chu Ming Chung, we concluded that theoretically, if we can produce sufficient gravitational wave from a massive object that is moving in an extreme speed, it is possible to achieve faster-than-light travel relative to a inertial reference frame.

# Could this FTL idea with a fast moving large mass be possible?
I have recently come up with a possible way to achieve faster-than-light (FTL) travel by using a high speed singularity or large mass.
## Background
As everyone knows, according to relativity, under normal conditions, it is impossible for anything initially slower than light become as fast as light or even faster, because anything with mass requires infinite energy to approach speed of light.
However, speed is not the only factor of relativity, gravity will affect it as well. There was an [experiment]( shows that even light will bend as it travels near a strong gravitational field, for example Sun. That observation shows space can be stretched with strong gravity, and give some insight to this idea.
