7 Mind Bending Physics Facts ...

My worst and least favorite subject at school was physics, but as Iโ€™ve grown older, I have gained more interest in physics facts.

I donโ€™t profess to fully understand many that I hear or read about, but Iโ€™m a very inquisitive person and love to know how things work and the science of potentials, would have, could have and should have, is far more fascinating to me these days than when I was made to study it.

Actually, I am pretty much in awe of the scientists who establish physics facts โ€“ such as these:-

1. The Speed of Light Varies Consistently

You know that light has a speed โ€“ yes?

It's 671 million miles/hour.

Thatโ€™s the fastest speed anything can travel, which was laid out by Einstein in his Theory of Relativity.

However, light does not always travel at this top speed.

The speed of light slows down in a medium, such as glass or water.

In fact, if the medium is dense enough, you can slow the speed of the light travelling through it right down to a trickle!

This is just one amazing fact about light.

I learned last night watching Stargazing on BBC2 that light also bends, which is another amazing thing about the universe, again quantified by Einstein and his theory which is the source of many fascinating physics facts.
