\"LightSpeed<\/a>
\nCurrently the speed of light in a vacuum<\/a> is just a hair under 300,000 kilometers per second (more precisely 299,792,458 kps).<\/strong><\/p>\n

“In 1983, the metre was redefined in the International System of Units (SI) as the distance travelled by light in vacuum in 1\u2044299,792,458 of a second.<\/a>“<\/p><\/blockquote>\n

Because the speed of light (known as “c” to mathematicians and physicists<\/a>) does not exactly match 300,000 kilometers per second, it makes calculations for physicists and mathematicians unnecessarily tedious.\u00a0<\/strong><\/p>\n

The speed of light<\/a> is a law of nature<\/a> that we cannot adjust. By contrast there is no law of nature that defines either the meter<\/a> or the second<\/a>. Both are human ideas that comprise a human set ratio – which we have adjusted in the recent past.<\/strong><\/p>\n

There is no reason one of the two cannot be adjusted by such a trivial amount so that the speed of light in a vacuum is exactly 300,000 kilometers per second.\u00a0<\/strong> Many mathematicians already approximate it to 300k-kps anyway.<\/strong><\/p>\n

It would merely require shortening the definition of a meter, or lengthening the second — by a minuscule 0.0007 percent.<\/strong><\/p>\n

The General Conference on Weights and Measures<\/a> is the International body which determines Standard Units of measure. They change units of measure when they can be made more useful or more helpful.<\/strong><\/p>\n

Amazingly, they are working on changing several units of measure right now, but not the meter or the second<\/a>.<\/strong><\/p>\n

If you agree, why not let the General Conference on Weights and Measures<\/a> know. You can get them a note at (webmaster at bipm (dot) org).<\/strong><\/p>\n
