The childlike answer is, “ Yes, it is possible to stop clock time. All you need to do is travel at light travel rapidly. ”
The rehearse is, true, a morsel more difficult.
Addressing this issue requires a more exhaustive exposition on special Relativity, the first of Einstein ‘s two Relativity Theories. ( limited – 1905 ; General – 1916 ). extra Relativity pertains specifically to inner light. The cardinal dogma is that light focal ratio is constant in all inertial reference frames, hence the reference of “ coulomb ” in citation to light. To phrase this dogma in a more friendly manner, it means that a light beam ‘s amphetamine remains unaltered even if the perceiver moves proportional to it. This consistency is wholly extraneous to us macroscopic world dwellers, because an automobile ‘s travel rapidly appears to increase if one is moving toward it and seems to decrease if one moves away from it. Light ‘s behavior is unlike.
We know that an object, or a light shine ‘s, speed measures the distance traversed over prison term. How can we reconcile this relationship with the fact that a light beam ‘s measured speed remains constant for all observers, moving or stationary ? Time dilation affects this reconciliation.
Time dilates on moving vessels : the greater the speed, the greater the time dilation. lone when such velocities * border on light accelerate do such effects become significant. If, and this one of those extreme IF ‘s, a vessel could attain alight accelerate, time aboard the vessel would cease wholly. Any person on that vessel would experience nothing at all. Though Spock and Kirk are able to trade barbs and witticisms at warp, in the real populace, they would experience no clock time at all. Let ‘s say, to play with this illusion world a piece, that a vessel moves at light speed from now ( 2014 ) to 2214. For us, two hundreds years would elapse. No time would pass at all on the vessel. What would be two centuries on Earth would be instantaneous on the ship.
Extremely strange, but, theoretically true.
now, we ruin the moment when some pragmatism : accelerating a ship to such a speed is not possible, at least not with our engineering. The trouble is that a vessel ‘s mass besides increases with increasing speed. A vessel at light rush would have countless bulk ! special Relativity indicates that a vessel ‘s mass increases, distance contracts with increasing speed. Time dilation is not the alone effect.
The fastest homo made vessels, the Helios Probes I and II, established heliocentric orbits that were closer to the Sun than Mercury. consequently, they attained speeds of more than 170,000 miles per hour. here, we extend ampere much credit to the Sun as to the engineers, for these impressive speeds. however, even the Helios probes moved at less than 1/3600th light speed : not particularly impressive by Starfleet standards.
Will we ever construct starships capable of light rush ? ( In so doing, we could send people to remote locations without worrying about them aging to dust or getting on each others ‘ nerves. ) We ca n’t today, but who knows what humans will finally accomplish ? We surely hope so.
* Using the terms ‘speed ‘ and ‘velocity ‘ interchangeably is not precisely an excommunication umbrage, but should be avoided. accelerate is a scalar quantity : 100 miles per hour or 90 kilometers per second are both speeds : values without focus. Whereas 100 miles per hour east of the police barracks is a meter of speed, as it includes a steering. We use them synonymously out of sheer indolence.
