I always thought that treating type 1a supernovas as "standard candles" was kindof suspicious

As if every supernova is exactly the same... BS!

At the same time, why not use a shorter wavelength, e.g. X-Rays, or gamma rays, and triangulate distances? Angles too small? Make better measuring devices!
