The Big Bang Theory

What if the big bang is not the beginning? It just happens in cycles where all the matter of the universe and beyond comes together and then explodes again every couple of 1,000,000,000,000,000,000,000,000,000 years? It has been theorized that black holes merge (when that happens galaxies merge) and become supermassive blackholes. In 5 billion years the milky way and andromeda will merge, and no doubt turn every molecule into atoms. What if all black holes eventually merge until it becomes one big blob of explosive mass? the big bang is the start of life for the current universe. and i guess it really doesn't matter because all things will cease to exist when it merges or explodes again. that is the end and start of all life.
