The Universe was and is and continues to be constantly expanding. Each millennium, century, decade, year, hour, minute and second, more and more of The Universe unfolds and stretches and simply becomes.
Fresh gorges of dust and stars and planets build up and up, forcing The Universe to grow, to push out in new, reckless directions.
If it was even possible to calculate the ever increasing mass of The Universe, it would be immense, beyond immense, beyond all human and other worldly comprehension.

Which, as the doctors had all concluded, was further proof that The Universe was severely obese.
