Alright, there was already a recent proposal to nerf it. This isn't the same, so please read my proposal carefully before bashing it to hell and back.
What is Telescience?
Telescience is a Science mechanism that allows teleportation to and from a telepad to any given coordinates. If this sounds overpowered, that's because it is. For this reason, it requires a lot of math and is absent from Science roundstart, as a balance mechanism.
My proposal is that it is still overpowered, and should be removed, as the core concept of it is fairly flawed.
External Programs
As Telescience is mostly mathematical, it is possible for someone to create a spreadsheet or external program that does the math for you. In fact, this actually did happen on /tg/.
"But Tar," you say, "You're being a clown right now. Just ban external programs!"
Well yes, this could be done, and kind of already is thanks to the metagaming ban, except this would also ban scientific calculators. You know. The intended method of using telescience.
Unless someone writes down the math on an ingame sheet of paper or something, we can't very well go around bwoinking people saying "HOW DID YOU FIGURE OUT THE DIFFERENTIALS LAWBREAKING SCUM?".
Legitimate Uses
There aren't really that many legitimate uses for telescience. Basically just things like looting the armory, teleporting bombs into the AI core, teleporting bombs elsewhere...
Unless the AI is malfunctioning, there's not that many reasons for non-antags to actually use telescience. It's a solution without a problem.
I'm not sure if space loot is randomized (I've never gone exploring space before), but if it isn't then that's also a problem because you can essentially use telescience to get space loot without any effort.
Furthermore, there also isn't a real way to counter telescience. A traitor scientist armed with the math (or maybe one of those external programs) and the willpower to build a telescience set (which isn't that hard, it's just a telepad or two and a computer last time I checked) can snap their fingers and wipe out anything with practically no effort.
Can Telescience Be Saved?
Yes, Telescience is very overpowered. This is why it has been given it's downsides. Making it very hard has already been tried, and as I have shown, that won't necessarily work.
There aren't that many other ways to nerf it. You could, perhaps, make it frustratingly random, but then no one would use it and you might as well just remove it.
In conclusion, telescience is very easily exploited, is difficult to balance due to the very nature of it, has no real reason to be used by nonantags, and the main balancer (math) can be worked around.
For this reason, I am requesting that the telescience machines be made unavailable for building by the crew.
Thank you for reading.
