As far as I am concerned the Big Bang has been firmly established. Looks like Father Georges Lemaître was right after all! LOL 
Was Father Georges Lemaître Right?
We don't know. Why not simply admit that we do not know if the universe is finite or infinite?
But more is being revealed every day about the Little Bang that made the Solar System right here [Science 195, 208-209 (1977); Nature 277, 615-620 (1979); Geokhimiya no. 12, 1776-1801 (1981); Meteoritics 18, 209-222 (1983)].
Naked science readers may be interested in reading about the similarity in the one of the shapes allowed for electrons in the 3d orbital of the Hydrogen atom (two dumbbells passing through the hole in a doughnut) to the supernova debris that formed the Solar System five billion years (5 Gyr) ago, . . . .
And to the events that more recently formed SN 1987A and the Planetary Nebula Eta Carina:
Let's celebrate new information that is being revealed today and stop arguing about information that none of have yet.
