Time and relativity


The distance between the Midwest (US) and Windhoek, Namibia just got two hours shorter over the past month. To attempt to derive a physics-based explanation for this unusual phenomenon, please click here. However, for a logical explanation, read on...

When we arrived in Windhoek in January, the time difference between Nebraska and Namibia was 8 hours. Nebraska is GMT-6 (6 hours behind Greenwich Mean Time), and Windhoek is GMT + 2. Both Nebraska and Windhoek were on 'standard' time in January.

However, the States' Daylight Savings Time meant Nebraska jumped one hour ahead in March ("spring forward"). As of today, April 5, Namibia moved back an hour ("fall back") to observe "Winter Time". So, for the next few months, the time difference between Central Time in the States and Namibia is now 6 hours.

Doesn't that make you feel like we're that much physically closer? That's what Einstein was thinking when he postulated, "The physical distance between two locations on a spinning planetary body can be measured by the difference in the time at which individuals in the two locations eat breakfast." Or, something like that. My apologies, Albert.
