Guest Fashiontrance Posted October 24, 2003 Posted October 24, 2003 General Relativity states that a magnetic field cannot rotate faster than the speed of light in a vacuum, but the Hubble has observed some pulsars that rotate about once per second. They have strong magnetospheres that extend beyond the point where the magnetic field is rotating faster than light speed. Are the phenomena that occur at this circumference known?
YT2095 Posted October 24, 2003 Posted October 24, 2003 the "beam" that`s emited would become a curve, a bit like those rotating garden sprinklers, or if you pointed a laser at the sun and then swept across to point it at alpha centauri (4.7 light years away), if you did that in 1 second, the beam would still travel at light speed, but looking frome the top down, it would appear as a curve. on a pulsar a top down veiw would look like a swirl, with the outermost sprirals being tighter together.
aman Posted October 24, 2003 Posted October 24, 2003 If you do a google search for "Gravity Probe B" you will see a good explanation of the physics of rotating gravity sources and their expected effects on space. It will be launched in Nov. and its data is something to look forward to. Just aman
