If I got your question right, then what we today is a fully stretched extremely small point. Light cannot travel faster than light and this is a fact. However, the theory of relativity and quantum mechanics do not work at the very beginning of the universe. Stretching of the universe is already quantified but involves high level math. | |

I do have one question though. It was implied that the first light years have stretched a considerable amount a when compared in distance to light years today. Do we know if light travelled faster than 186,000 miles per second? or if those miles have just stretched in length since early universe? If it is the latter then shouldn't that stretching be quantified and updated like leap seconds? or maybe that's the same thing?.... mind blown... ok marked as answer. Thank you | |
