Timely thread.
I’ve been working on a solar slab, guaranteed to withstand the heat of the sun at a distance of 4,000,000 miles from the surface, confirmed by a clandestine NASA mission, known as the Parker Solar probe. Long after you become a celestial vapor trail from global warming, your collection (assets) will be safe in a yet to be determined undisclosed location.
And to borrow a line from Gentleman’s Warehouse, “I guarantee it”. Just send me a SASE addressed to your anticipated location in the cosmos ten years from now. If nothing else, we’ll find out how good those “Forever” stamps are.
