So, you know David and Will who are our stalwart writing team have been actually having some conversations with proper real scientists because we're finishing up the Star Map which is another thing that we'll be sharing with you guys at CitizenCon and I think you guys will really like it – it's pretty damn impressive. So, we're consulting with real astrophysicists to try and flesh out the rest of... some of the science and the physics of the fiction, the universe, and the planets. So, we're definitely doing that. Tony is very keen on having quite a bit of scientific research and realism so we actually have some dedicated ships – we have the Endeavor that's coming up which will be its own science platform. We have a variant of the Reliant that will be more of a science/research based vessel. We have a few other things where there will be non-combat-based gameplay. So, one obviously is exploring and charting areas but another one will be actually analyzing – basically like getting on the tail of a comet and figuring out what the composition of the comet is when you're following behind it and then later on you can maybe – based on that, you take that data back to the UEE and sell that for money.So, we're going to have various parts of gameplay that involve science and research whether it's researching stuff down on planets or in asteroid fields or things like comets as I mentioned. Obviously we sort of have a science fiction universe so there's a certain amount of fantasy elements to the science fiction because if it was hardcore science, probably in 2900 it wouldn't look exactly the way it does in Star Citizen. Star Citizen's sort of more a... kind of our childhood-imagined cool SciFi universe. But we do try to infuse in various principles from science and various physical stuff to make it feel more tactile and more real.Don't know if we'll be able to solve the mystery of dark matter in the Star Citizen universe... but you never know.But, we are actually working and talking to people who know what they're talking about as far as all of this, to make everything feel more real than normal.
