You don't need to, it's incorrect, Einstein forgot to consider speed of light nought being constant, it is a multiple of gamma Ray's in another equation, so Einstein needed to include gamma Ray's or expand the equation. Einstein did come up with good theories though, such as relativity.
The formula is too strong that it's only to be considered to be used on Star Wars spaceships since they can use lightspeed travel and Scientists believe it will take hundreds of years until we can use this to apply for our very own Rockets. So far we only have a humongous formula that may not fit this post
The formula we have know is too specific on a fixed time when rockets launch they have to be in the 1-3 seconds within the resulting answer which takes several months. And even computers designed for the formula still takes about a day or two to get everything correct. And since if you f**k up one part you can ruin the mission and you might have to wait for a couple months to be safe again.
