I’m Ti (short for Tiana) and I, unlike many people really enjoy doing math.

I’m Nic and I ❤️ Math✌️

Anonymous said: Can please explain why time slows down when an object travels towards speed of light. Or even stops when travelling at speed of light? Thank you in advance.

astronomicalwonders:

So, as you know, we have a cosmic speed limit. That speed limit is 299,792,458 meters per second… That is very fast. I’m going to call this maximum speed, which is also the speed of light in a vacuum, ‘c’ from now on. The fastest speeds we have ever made by man/woman have been at the Large Hadron collider where we have sent electrons up to 0.99999991% the speed of light. Smashing together subatomic particles at these speeds help scientist discover what they are made of.

So your question is: why does time slow down for objects traveling at these speeds? Well, this phenomenon was actually predicted by Einstein and can be explained by his equations. Einstein called it a “time dilation”. So what you want to know is: how does speed cause a time dilation? This is actually a special case of a time dilation (yes there is more than one way to have a time dilation!) and is called a “relative velocity time dilation”

Nontechnical explanation of “relative velocity time dilation”:

"When two observers are in relative uniform motion and uninfluenced by any gravitational mass, the point of view of each will be that the other’s (moving) clock is ticking at a slower rate than the local clock. The faster the relative velocity, the greater the magnitude of time dilation.”

I the above graphic: From the local frame of reference (the blue clock), relatively accelerated clocks move more slowly. Now, one may ask “but from the local reference frame of the red clock doesn’t the blue clock seem to be moving slower?”. This question may seem to generate a paradox but, with an understanding of the technical aspects of a velocity dependent time dilation, it is not paradoxical.

File:Time dilation02.gif

For the above graphic: “The green dots and red dots in the animation represent spaceships. The ships of the green fleet have no velocity relative to each other, so for the clocks on board the individual ships the same amount of time elapses relative to each other, and they can set up a procedure to maintain a synchronized standard fleet time. The ships of the “red fleet” are moving with a velocity of 0.866% c with respect to the green fleet. The blue dots represent pulses of light. One cycle of light-pulses between two green ships takes two seconds of “green time”, one second for each leg.

As seen from the perspective of the reds, the transit time of the light pulses they exchange among each other is one second of “red time” for each leg. As seen from the perspective of the greens, the red ships’ cycle of exchanging light pulses travels a diagonal path that is two light-seconds long.

One of the red ships emits a light pulse towards the greens every second of red time. These pulses are received by ships of the green fleet with two-second intervals as measured in green time. Not shown in the animation is that all aspects of physics are proportionally involved. The light pulses that are emitted by the reds at a particular frequency as measured in red time are received at a lower frequency as measured by the detectors of the green fleet that measure against green time, and vice versa.

The animation cycles between the green perspective and the red perspective, to emphasize the symmetry. As there is no such thing as absolute motion in relativity, both the green and the red fleet are entitled to consider themselves motionless in their own frame of reference.

Again, it is vital to understand that the results of these interactions and calculations reflect the real state of the ships as it emerges from their situation of relative motion. It is not a mere quirk of the method of measurement or communication.”

Technical explanation of “relative velocity time dilation”:

here is Einstein’s equation for determining time dilation:

\Delta t' = \gamma \, \Delta t = \frac{\Delta t}{\sqrt{1-\frac{v^2}{c^2}}} \,

in this equation t represents time, v represents, c represents the speed of light in a vacuum, Δt is the time interval between two co-local events (i.e. happening at the same place) for an observer in some inertial frame, and γ represents the Lorenz factor which is given by the following equation (just a subset of the previous equation):

\gamma = \frac{1}{\sqrt{1-\frac{v^2}{c^2}}} \, .

The above is a graph of the Lorenz Factor as a function of Speed. With this it becomes clear how the Lorenz Factor causes time to pass faster or slower depending on speed.

I can hear some of you saying now “That’s not real, the math just happens to work out”…but what if I told you this has been tested hundreds of times? Our satellites, Smart phones and even the International Space Station have to operate under these rules in order to function. This has been proven with observation time and time again. (pun intended)

Great Question! it’s good that you are thinking of these things! DFTBA
