This is planet money from NPR.
Hey, folks, today we're going to share one of our favorite episodes of planet money from years past.
It's from 2019, and it's one that I love very, very much and I think about all the time, and we hope you enjoy it.
Here is something that I learned recently in the air above us.
Up at 35,000ft, it is the same time everywhere.
Universal time, which is the time at the Greenwich Meridian, is used all around the planet Earth today by every single airline and air force in the world.
This is Dick Henry.
Hes an astrophysicist at Johns Hopkins University.
And he said, think about it.
There are all these planes flying all over the earth at hundreds of miles an hour, and you don't want to get confused by time zones when you're trying to keep them from crashing into each other.
Dick has talked to his friend Steve Hankey about this for years.
Steve's an economist, a professor of applied economics at Johns Hopkins, and he says it is not just pilots who need universal time, investors need it, too.
You can trade 24 hours a day almost around the clock in gold, currencies, stocks and everything else under the sun.
And those are all times stamped using universal time.
Hanke and Henry were telling me about all this because they have this little proposal.
Yes, Steve and I want to abolish the time zones.
No more time zones.
We want 24 hours world time, everybody on the same clock.
You're fully serious about this?
Is this a serious proposal?
