new supernovae

[harls]

i was reading in my astronomy magazine that scientists have discovered a new type of supernova that was thought only theoretically possible but a 2002 supernova didn't fit the stereotype (white dwarf exploding or the collapse of a highly massive star) but this supernova is relatively faint, quick and doesn't have the scattering of elements that other supernovas produce. and there is other info but it doesn't relate to my question, would it be possible that some of these supernovas that're weaker that regular ones have happened further than 13.7B light years away but produced a light dim enough to not reach the reaches of our sattellites? thus leaving our belief that our universe is so far only 13.7B old like we think?

Do you mean this?

If by “would it be possible that some of these supernovas that're weaker that regular ones have happened further than 13.7B light years away” you mean could stars have existed more than 13.7 bya, then the answer is no. We don’t have to subject the age of the universe to belief or assumption. We know it. Check out the timeline of the universe from WMAP.
