It all comes down to whether you think the speed of light is constant in SR, and experiments indicate it is.
it takes 1m yrs for him to get there, so 2m yrs before earth sees the traveller arrive.
The journey is not faster than light for the rest frame of earth and the planet, it takes 1m yrs for him to get there, so 2m yrs before earth sees the traveller arrive.For the traveller the distance to the planet is shorter and so is not faster than light. The elapsed time experienced by the traveller is only 3 yrs, but it is yr 1m for the planet (and earth) when he arrives.
No such thing has superluminal travel

I am sure not because it does or not exist, I am sure because it will never be allowed to exist.

It just seems odd that most forums defend theories as if definitive facts, as if the accepted theories are not aloud to be questioned, set in stone as such.

Most of us have a love for science and are trying to gain a better understanding than our for whatever reason inadequate education provided us with. Regular taught in schools science has developed through an ever changing understanding to where it is now. Although individual names stand out in a study of the evolution of science, the directions it takes in approaching the truth of anything, is driven by humanity. It has more to do with discussions over a coffee or a beer than the laboratory.For this to work there has to be a basic accepted system of mutual understanding of the basic conventions. Just for clear communication, the participants have to be using the same language with the same grammatical rules. This is especially true with the language of mathematics. If anyone is to present a new or in any way novel idea, they can't be doing it by expecting everyone to learn new definitions for an established language.Mathematics is structured enough that it can adequately describe multiple dimensions with different laws of nature to this one. I'm sure that in there exists the right form to clearly display what is in your imagination. For all I know you could be the modern day Einstein. But if no one can understand you, your talents if they exist, will never be available to the world.I strongly recommend you do some math refresher courses. There are a number of MOOKs available.Then when you can present your revolutionary or not ideas, at least the rest of us can understand what you are trying to say.Without having to learn your version of maths, and we can join into more positive conversation.
I use the present symbols, I put the symbols into sentences, I do not understand what is hard to understand about your own symbols.

Just like every other language, math has grammar. There is a way to use it that is understood. Using the same symbols in ways that do not make grammatical sense or attaching definitions to them that are contrary to what your peers use, just does not lead to communication. Whatever idea you are trying to communicate, gets totally lost in what is seen as drivel.Learn the language, not just the symbols.

But what if there is no present maths that describes what you are trying to describe, doesn't the maths come after the idea ?
