Do you trust your own senses?

About the Earth

My personal experience tells me that I can usually trust my own senses, most of the time.  I wouldn’t be surprised if you feel the same way.  Granted, there are times when our senses struggle to make sense of certain things we see, “is that a mirage?” and other things that may appear distorted because of light, temperature and our own limited visual perspective.

We are told the mathematical formula for the curvature of the Earth is 8″ for every mile squared (i.e. 5 miles:  8″ x (5 x 5 miles) = 200″ or 16.7′ of curvature.  Think about that.  Then think about how that should effect what we see or don’t see.  Play with that curvature calculator for a bit.

Here are some things NASA tells us about the Earth:

  • Earth’s diameter is about 8,000 miles
  • Earth’s average distance from the Sun is about 93 million miles (WOW that’s really far away!)
  • Earth orbits the sun
  • Earth spins at just over 1,000 miles per hour at the equator (Really?  So how can an airplane land on a moving runway that’s spinning towards or away from it like that?)
  • Earth’s axis is tilted at an angle of 23.5 degrees
  • Earth is 238,000 miles from the Moon (That’s really far away, too.  So, how can we see craters on the moon if it’s really that far away?  How far can you really see?)

If these statements and questions have you shaking your head and feeling a little bit confused, that’s good.  But don’t stop yet…keep going.

What about the Stars.
