In fact, people had talked about it for a long time, but they could never simulate properly whether it would work or not, and so it's through the advent of modern supercomputers that now you can simulate and see that, yes, with the right materials approach, this looks like it would work.
Padahal, orang-orang sudah membicarakannya sejak dahulu, namun mereka tidak pernah mensimulasikan secara layak apakah itu berhasil, jadi berkat kemajuan komputer super yang modern Anda bisa mensimulasikannya dan melihat, ya, dengan pendekatan material yang tepat, hal itu bisa berjalan.
