I am currently applying for a grant to continue my research into what will happen both locally and cosmically 100, 1000, 10,000, 100,000, 1 million, two million, three million etc., 1 billion, two billion, three billion etc. years from now. I’m sure you will appreciate that this is extremely time-consuming work, and I’d be most grateful for your support and that of our readers. $1 million per annum for the next ten years would do me nicely.
