Law?

Wast the theory of relativity recently proven? doesnt that make it a LAW? —Preceding unsigned comment added by 68.121.84.218 (talk) 02:33, 8 April 2009 (UTC)[reply]

This isn't how science works. Laws are statements of fact, theories are explanations of facts.Triune (talk) 17:14, 13 April 2009 (UTC)[reply]

But the theory of relativity or better law of relativity is proven! So it has to be a law.--PaBraun (talk) 13:44, 12 June 2009 (UTC)[reply]

Gravity was proven by newton, until einstein proved otherwise. we generally leave theories as theories.Seeasea (talk) 17:58, 31 August 2009 (UTC)[reply]

If relativity is made scientific law this would supersede Newton's laws ( making them Newton's rules? ) maybe physicists are not ready to throw uncle issac under the bus just yet. OR MAYBE relativity has not been DIRECTLY observed. —Preceding unsigned comment added by 68.57.255.130 (talk) 03:12, 25 January 2010 (UTC)[reply]

Or * M A Y B E * you could take a course in physics, actually learn something, and stop speculating. Dan ☺ 07:30, 25 January 2010 (UTC)[reply]

biography

Albert Einstein was born in Ulm, in Wurttemberg, Germany, on March 14, 1879.Einstein died onApril 18, 1955 at Princeton, New Jersey.Albert Einstein married his cousin the same year he divorced his wife, Mileva Maric. —Preceding unsigned comment added by 24.90.186.233 (talk) 01:59, 21 December 2009 (UTC)[reply]

History

The theory of relativity, which has revolutionized the mathematical and physical concepts of modern times, is known to have been put forward by Albert Einstein early in the 20th century. However, we find that 1100 years before him Al-Kindi, a Muslim scientist and philosopher, had laid down the foundation of this theory.^[1]^[2]^[3] —Preceding unsigned comment added by Islamuslim (talk • contribs) 10:43, 22 March 2010 (UTC)[reply]

As these are not available online can you please quote the exact wording that you believe supports your assertion. Martin Hogbin (talk) 11:14, 22 March 2010 (UTC)[reply]

how to travel double the speed of light

If you are travelling at the speed of light and you are hurtling towards something that is already travelling at the speed of light, it would thrust you forwards therefore making you travel faster.

Scientists around the world, please may you look at this theory and put it into practise, because I am only 12 years old and i would like to know if my theory is correct — Preceding unsigned comment added by Freewebster (talk • contribs)

Velocities do not add up in the way that you think. Have a look here [1]. If you want more explanation I suggest that you ask a question on reference desk Martin Hogbin (talk) 17:43, 26 April 2010 (UTC)[reply]

Is it possible to have a Light Boom just like Sonic Boom after the "Light Barrier" is breached ?

1) Is Light Boom or a "Pressure wave" of Light possible if Light Barrier is breached ? If it did what could be the consequence of such a phenomenon ?

2) Is it valid to assume that Light will retain the "Wave" character for objects traveling at sub "C" speeds or will it be a case Light being considered as "Wavelet"/"Photon" ?— Preceding unsigned comment added by 61.17.93.121 (talk • contribs)

Please put these questions to the Science reference desk. This is really not the place for this. And don't forget to sign your messages. Thanks & good luck over there! DVdm (talk) 16:28, 27 April 2010 (UTC)[reply]

Also, look up Cerenkov radiation Martin Hogbin (talk) 22:04, 27 April 2010 (UTC)[reply]

time dilation

Shouldn't we talk about time dilation? Δt/ $(1-v^{2}/c^{2})^{.}5$
