After the Big Crunch ... is there life? Many scientists suppose that, if at some point the Big Crunch happens, the whole universe will be contained in that singularity, and the propitious scenario will be given to begin a new universe.
The truth is that the Big Crunch would be like rewinding a cassette: everything that has been built is gradually unraveling, until returning to the starting point. But this can do something redundant, since it is almost impossible for this theory to emerge. Today, 73% of the universe is dark energy, 23% is dark matter and common matter-planets, for example-only equals 4% of the total.
I see you've been working away for quite some time with very little recognition. There are ways forward for you as long as you can produce quality content. I suggest you go to @littlescribe and take a look at some of her tutorials. And as far as dark matter: dead in the water. Astro physicists have determined the theory does not work. You might want to go to suspiciousobservers on YouTube, there are some excellent vids on the subject. Blessings and good luck.
