How much does that cause the diameter of Earth to expand each year?
I’m in this thread only for the anticipated entertainment of Freepers!! :-)
YOU may be Oprah, but not me!
NASA is still spotting junk fading into space they are to far away from the gravity field.
I thought the Earth was looking a bit chubbier.
Everything you are, know, will ever be, has existed, or will ever exist in the universe is stardust, from the alpha to the omega.
Ehhhhh atsa good one, boss!
When the last atom has died the great void appears.
