In the past, scientists ranging from Prof Stephen Hawking, the Cambridge University physicist, to Albert Einstein, have argued that the universe eventually will stop expanding and then implode under the force of gravity, destroying all life. It's been determined that in 70 million years, the sun will burn out! I guess that means that the Department of Transportation will have to finish the Grandview Triangle in the dark!

I suspect that it will take a little longer than 70 million years.
