I mean even by the stuff he talks and the fcat Paps said Sans is into science. You bring up an interesting point, but what Cheeseskates and I are arguing is that these facts do not confirm a connection. They certainly hint at a connection. We do know, as you point out, that Sans is into science. We also know that Sans and Alphys know each other. We also know that Sans has some chips in the fridge and some instant noodles in his room. This information, though, can't actually get us to the definite conclusion that Sans knows or has been in the True Lab.

Allow me to propose a counter-hypothesis: Since Sans knows Alphys, and has a guard station near her lab, perhaps Sans occasionally goes to visit Alphys when he's in Hotland. On some occasions Alphys is willing to give him some food to take back with him, and since she has both chips and noodles (Alphys eats the chips as well, as she says at one point), that's what Sans takes back with him, thus explaining how these food items got into his house.

This hypothesis explains the same set of facts without saying that Sans knows about the True Lab or has been in it. Of course, the hypothesis I have put forward has the same merit as yours, since both are not explicitly proven. But without such definitive proof, we cannot say for certain that Sans does know about the True Lab. It's only a possibility.
