James Clerk Maxwell Error ?

What is the speed of light?

Light is faster than anything else in the known universe, though its speed can change depending on what it's passing through.

Around the turn of the 19th century, physicist James Clerk Maxwell created his theories of electromagnetism. Light is itself made up of electric and magnetic fields, so electromagnetism could describe the behavior and motion of light — including its theoretical speed. That value was 299,788 kilometers per second, with a margin of error of plus or minus 30. In the 1970s, physicists used lasers to measure the speed of light with much greater precision, leaving an error of only 0.001. Nowadays, the speed of light is used to define units of length, so its value is fixed; humans have essentially agreed the speed of light is 299,792.458 kilometers per second, exactly.

Electromagnetism suggest light has electrical and magnetic properties . However , how true can this be when present physics also implies the contradictory of this ?

A compass needle is attracted to the North and South magnetic pole because of the magnetic properties and electrical charge is always grounded by a body . What this implies is that if light was electromagnetic as implied by Maxwell , the light would be grounded by its own source and additionally affected in velocity by any magnetic fields . This information implying that if light was electromagnetic , it would not behave the way it does .

Additionally light passing through space has zero net charge , there is no evidence to suggest anything electrical . Also , the Suns temperature is too hot to sustain any sort of magnetic field .

In physics and materials science, the Curie temperature (TC), or Curie point, is the temperature above which certain materials lose their permanent magnetic properties
