The Principal of Invariant Light Speed

scinote:

Question:

Is it possible that outside of our frame of reference, we are traveling at the speed of light, but we don’t sense it because everything else in our frame of reference (the observable universe) is also traveling at the speed of light?

Asked by the-apiarist

Answer:

Great question! The Principal of Invariant Light Speed, one of Einstein’s postulates, states that the speed of light in a vacuum is constant no matter the frame of reference. Therefore, no matter the observer, the speed of light provides the same limitations on motion.

In short, probably not. It isn’t entirely impossible, but our current knowledge of the universe makes it highly improbable.

Invariant light speed is such a counter-intuitive concept so misconceptions about the things related to the speed of light is quite common. But people who are much smarter than us can explain these concepts to us in plain language, thankfully.

Happy July 4

July 4 is not just a special day for the Americans, it is also a special day for Physics and for Science in general. The discovery of Higgs Boson was announced at CERN 2 years ago today.

So, happy Independence day to all those in the United States, and Happy Higgs Boson day to all the Physicists, Scientists, and Science students and enthusiasts around the world. 

P.S. I was looking through July 4 events list on Wikipedia and i realised that July has been a good day for science on more than one occasion.
