In case you didn't know, Albert Einstein was a scientist. He produced the famous E=mc^2 equation you've all heard of and probably never had to use (Unless you took a further Physics course beyond school)
This itself is intriguing because it shows something moving faster (Therefore has more kinetic energy) actually gets heavier.
But this is just the beginning...
You've all heard of the theory of relativity, right?
But do you know what it actually means?
[b][h2]Special Relativity[/h2][/b]
Special relativity states that time (and distance) measurements begin to change the closer you get to the speed of light. Thats right, the faster you go, the slower time goes for you. It's like motherfucking [b]time travel[/b].
Lets put this into an example.
Face has a twin called Punch. One day, Punch says:
[b]"Face, I really want to shift time a little just to mess with people"[/b]
[b]"lol no, herp, thats not fucking possible."[/b]
[b]"But it nearly is...I bet I can be younger than you in the future"[/b]
[b]"Why the fuck are you so retarded, we're the same age and it will stay that way. I hate you Punch."[/b]
So, Punch, being the most intelligent fucker you'll ever hear of, builds a rocket that can travel at 95% of the speed of light.
Punch leaves Earth at the age of 25 and travels at 95% of the speed of light for 5 years (In his time) and lands on a distant planet.
"[b]Fuck this I forgot to bring my laptop to play Minecraft.[/b]"
So Punch travels back to Earth to get his laptop at the same speed and it takes him another 5 years.
When Punch arrives, he is aged 35. He goes back to his house and finds Face walking around the house with a zimmer-frame.
"[b]What the fuck happened to you, Face? You look like a prune."[/b]
Face is aged 57, while Punch is only 35.
Another strange scenario would be if your parent left Earth one day and traveled at 95% of the speed of light for a few years then on returning, [b]you would be older than your own parents.[/b]
Total mindfuck.

"A. Einstein - The greatest troll of science ever?"
A real life example of this is an experiment where two atomic clocks were synchronized. One clock was flown around the world while another remained in London. When the two clocks were bought together again, they were very slightly out of sync.
:science:

snap, interesting stuff
i thought everyone knew about this already

If that last thing about the clocks is true than that sure proves something. Just not really sure what........................................

it proves the faster something goes, time changes around it more
that is what it proves...................................

"Thing with the clocks" and the twins paradox is called time dilation, by the way (Its a part of special relativity)
Very interesting. You should read up on it because I really only scratched the surface!
How about general relativity? I may add that to the OP...

YOUR LONG LINE OF FULL STOPS IS STUPID.
I think it means that...you know what, you're right. I dont know what it means.
[QUOTE=Opacity;28950304]i thought everyone knew about this already[/QUOTE]
I'm pretty sure we all do, but its still interesting to read nonetheless.
I remember reading about this in an astronomy book my parents bought me in elementary school
I didn't understand anything in it, but the pictures were cool
I think at more than a hundred years old this can be considered late. Also, you need derivations man, get this shit right.
Why is that the only picture of Einstein I ever see? Is there any other one?
Didn't Red Dwarf do an episode on this called "Future echos"?
[QUOTE=Oscar_SP;28950330]If that last thing about the clocks is true than that sure proves something. Just not really sure what........................................[/QUOTE]
Of course it's true. It has been proven tons of times.
I remember I learned this from Calvin and Hobbes
I honestly see no reason to call it a mind fuck. It is simple enough to understand. Time is not uniform. The real mind fuck is when you start looking into the creation of the universe. After a while shit does not add up.
Science is awesome. :science:
i remember learning this as a little kid and trying to run really fast so i could be a time traveler
So what would happen if you sent someone off at 95% lightspeed for a 10 year round trip (your time) and they were the same age as you?
Time doesn't dilate as much as the OP states at 0.95c.
Edit:
Ops sorry I was wrong! The change factor thing is at 3.2 so OP is correct. Sorry!
I thought everyone already knew this.
EDIT: Sure, it's late. So is the original post.
Time Dilation is pretty simple.
Hardly a mind fuck.
Since OP for whatever reason hasn't explained it fuck it i will.

The essence is imagine this is a box with a light beam going up and down. When the box is moved very fast the light doesn't have time to get the top again from the bottom of the box, as such so it has to go diagonal in order to keep causality (what we see is what we get basically as in apples can't be oranges for example :P). Since diagonal is a longer line than straight up and down the time taken to cover increases hence time dilation.
Simple geometry and time=distance / speed can be used in order to find the time dilation. Try it and become Einstein or something like, just simple solve for the time it takes to cross 2D looking at the diagram.
wow. just wow.

Hmmm, well, I (for one?) am a firm disbeliever in special relativity.
Speed can only be taken in a specific frame of reference. How can we say that there's a universal speed limit when we're probably surpassing that speed on a large enough level (that is, speed relative to the earth, then the sun, then the system, the cluster, the galaxy, the galaxy cluster, etc)?
In my opinion, his most important (imo) discovery/soolution wasn't the theory of relativity or special relativity, but rather the solution to the Photoelectric effect by using Planck's constants and introducing photons. It did win him the Nobel Prize in Physics after all.
[quote=Wikipedia]
In 1905, Albert Einstein solved this apparent paradox by describing light as composed of discrete quanta, now called photons, rather than continuous waves. Based upon Max Planck's theory of black-body radiation, Einstein theorized that the energy in each quantum of light was equal to the frequency multiplied by a constant, later called Planck's constant. A photon above a threshold frequency has the required energy to eject a single electron, creating the observed effect. This discovery led to the quantum revolution in physics and earned Einstein the Nobel Prize in Physics in 1921. By wave-particle duality the effect can be analyzed purely in terms of waves though not as conveniently.
Albert Einstein's mathematical description of how the photoelectric effect was caused by absorption of quanta of light (now called photons), was in one of his 1905 papers, named "On a Heuristic Viewpoint Concerning the Production and Transformation of Light". This paper proposed the simple description of "light quanta", or photons, and showed how they explained such phenomena as the photoelectric effect. His simple explanation in terms of absorption of discrete quanta of light explained the features of the phenomenon and the characteristic frequency. Einstein's explanation of the photoelectric effect won him the Nobel Prize in Physics in 1921.[/quote]
Don't forget about length contraction. In addition to time being relative to the observer, measurement is also.
Consider a timing device in which a light pulse travels from one end to the rocket to a mirror on the other end and is reflected back to a receiver near the source of light. Also, assume there is an observer in a lab frame of reference and an observer on the rocket.
[IMG]http://www.drphysics.com/syllabus/time/fig2.GIF[/IMG]
L' = length of stick in the "rocket"
L = length of stick in the "lab"
t1 = travel time of light pulse to the end of the stick (lab)
t2 = travel time of light pulse back from the end of the stick (lab)
t = t1+t2 = total travel time in the lab
t' = total travel time in the rocket
v = speed of rocket in the lab frame
In the lab:
L + v*t1 = c*t1
L - v*t2 = c*t2
t = t1 + t2 = (2L/c)/(1-v2/c2)
In the rocket:
2L' = c*t'
t' = 2L'/c
We know from the time dilation formula that
t' = t*√(1-v2/c2)
So,
2L'/c = (2L/c)/√(1-v2/c2)
L' = L/√(1-v2/c2)
L = L'*√(1-v2/c2)
The stick appears shorter in the lab frame since √(1-v2/c2)<1.

Moving faster than the speed of light is a violation of electromagnetic theory. You can't just add velocities like you can in Newtonian mechanics.

We aren't.
as you approach the speed of light, you become your own grandma!
'twas an interesting read, though like everyone's said it's pretty common knowledge for being such a complex concept"
