Famed physicist Stephen Hawking recently predicted what he calls Starmus. He says that not just Earth, but the entire universe will some day totally self-destruct. And it could happen at any time ...a big bang... followed by nothingness.

With that sad fate in mind, we asked some of our most active senior travelers to choose how they’d spend that final moment. Some responses may amaze and/or amuse you:

Many of our senior career women readers are too familiar with glass ceilings. Now, travels can take them to sky-high places where they’ll enjoy glass floors and breathtaking views.

The venerable Eiffel Tower, celebrating its 125th anniversary, now offers visitors a high floor with a clear glass bottom that reveals the city of Paris 200 feet below. The millions of visitors who flock to the landmark each year can now stand and look down on the beautiful city. www.toureiffel.paris/en

Here are several other glass-bottomed attractions around the world:  CN Tower, Toronto, Canada: The see-thru walkway vision is 1,122 feet high, and first opened 20 years ago. www.cntower.ca

Skytree, Tokyo, Japan: At nearly a half-mile high, the world’s highest freestanding broadcast tower offers the glass-bottom Tembo Deck at its 1,148 feet level, surrounded by 360-degree views from huge window panels. www.tokyo-skytree.jp

On a recent flight, a self-appointed humorist told fellow passengers he had Ebola, then laughed and said he was just kidding. However, the pilot wasn’t kidding when he immediately returned to the airport and ordered a medical team in hazard suits. Result: A planeload of frightened, frustrated and delayed passengers, plus the jailed jokester faces legal, possible criminal charges.

We’re aware that many travel4seniors.com readers have spent responsible lifetimes in business, education and the military. Along with that serious career success, especially with ex-military, there’s often a creative sense of humor.

It’s on wheels and looks like a thinking bot. However, the self-propelled wheelie is actually just a live face on a TV monitor who answers questions from inquiring passengers. The Indy info expert sits in a studio somewhere in IND airport and operates a two-way sight and sound system.

Of course, some day everything will be run by real robots. They’ll actually steer ships, drive cars and fly airplanes. For veteran seniors who’ve been there and done that, there’s hope that armies of brave bots will also fight our wars. www.indianapolisairport.com
