Einstein's Special Theory of Relativity E=mc2 speed of light

The steps Einstein took to develop his special theory of relativity are as follows: First, Einstein tried to understand what must be implied by the fact that light travels at a speed independent of its source. From this, he realized that time and space are not simply two unrelated concepts; rather, they must be linked in a space-time system whose properties appear most dramatically when objects move very fast and are observed by two different observers moving with respect to one another. His final and greatest step led him to discover and clarify mathematically many new things about the world that are important in each and every frame of reference.
In each and every frame of reference, there are relationships that hold because of the nature of space and time. If space and time were to be reconceived in a new interactive way, then other things, like momentum and energy, had to be reconceived, too. In fact, momentum and energy are linked like
space and time.

Why isn't the train ... ( 3 weeks ago by GnarlyCharlie77)
Why isn't the train scenario considered simply an illusion. The lightning bolts did hit simultaneously but to the train rider it only SEEMS that oine happened before the other. The train rider could determine when the two strikes occured mathematically. Can someone help me out, I'm still trying to understand this stuff.

ColdFusion, black holes apparently do bend spacetime around itself so that nothing can escap, including massless things like light. It's very weird and im not even sure if I understand it yet, but thats what the scientists believe.

Yes, it is an illusion. But time itself is the illusion. If you believe that time is linear, then it will be impossible to understand something outside of that limitation. However, time cannot be measured, only perceived. The perciever is always right, and it two people perceieve the same thing differently, they are both right.

Theoretically if you could travel at the speed of light (like in star wars or something) would your body age? Would there be any physical changes? Maybe this question is stupid, too unrealistic?

Part of you is already aware of what it feels like to travel at the speed of light, assuming your body has energy. Do you feel all right?

so if the earth recieves 4.5 pounds of sun light/second.
4.5lbsX60/secondsX60 minutesX24/hours. does the earthes mass increase by 388,800 pounds every day??? assuming none of it is reflected back into space???
No. Photons have no ... ( 1 day ago by FizzyBublech)
No. Photons have no mass. When plants absorb them photosynthesis converts energy into chemical bond energies and other photons of lower energy in the form of heat. The heat is radiated back into space.
"If you are in a ... ( 1 day ago by FizzyBublech)
"If you are in a spaceship that is traveling at the speed of light, and you turn on the headlights, does anything happen?" Regardless of your motion, you will always measure the same speed for light, 186,000 miles per second which means, even traveling at the speed of light, when you turn on headlights, they light will travel away from you at speed C, regardless of your rate of motion.

"Would there be any physical changes? No, nothing would happen to you.Its a good question.

"ColdFusion, black holes apparently do bend spacetime" Light is not massless. Light can take the form of a particle or a wave. Black holes, are condensed mass whos gravity is so strong that light cannot escape. Think of stuffing all the mass of the earth into the size of an apple and you will have a black hole.If the gravity is strong enough, it can compress spacetime to an infinite degree hence, light will travel forever and never make it to earth.
"But time itself is ... ( 1 day ago by FizzyBublech)
"But time itself is the illusion." No, Time is not an illusion but it is not fixed either. The conductors motion compressed time in the direction he was traveling. They both experienced the same event correctly, just at different times. Neither can say, my point of reference is the correct one. To say it "seems" implies it didnt really happen, but it did. Its hard to wrap you head around I know, but you must accept both are correct. It struck both at the same time, and also one before the other.
if the lightning ... ( 1 day ago by pdxeddie1111)
if the lightning strikes both poles at the same time then the lightning hitting the second pole to conductor's observation would only appear later but not actually be later. same concept as a bullet hitting its target. you can see the bullet hit the target but you wont hear the shot until a fraction of a sec. later.
and some percievers ... ( 1 day ago by pdxeddie1111)
and some percievers are more right than others. lol If illusionist makes a ball disappear in front of someone that someone sees the ball disappear but to the observer at a better observation point sees the ball go up the illusionists sleeve. Which observer is correct?
An illusion is ... ( 23 hours ago by Locust59)
An illusion is something perceived that is misleading. Time is an illusion because you cant measure what you perceive time as, because it differs depending on the observer which makes it misleading. If it is misleading, it makes it an illusion. Of course nobody has a "correct" point of reference because "correctness" depends on a third party to comfirm. However, every perception is correct among the observer alone, so perception and relativity is everything in this case rather than correctness.
time is sequence of ... ( 17 hours ago by fikernafaka)
time is sequence of events some events come before the other event, so light come from a source say sun and it takes about 8 minutes, if i believe that time stops if some object travel as fast as light, in this case time for light should stop and obviously it should not take 8 minutes to reach on earth. can someone explain this to my.
Illusion: The ... ( 12 hours ago by FizzyBublech)
Illusion: The condition of being deceived by a false perception or belief. Your use of the word is incorrect. Time is not an illusion. With regards to correctness, lets say there was another conductor traveling in a train going the opposite direction You are saying that since now there is a 3rd party the correct perspective can be given? Problem is the 3rd conductors perspective is different from the other two, so who is right?
It depends on the ... ( 11 hours ago by Paulginz)
It depends on the reference frame. To us, on earth, it looks like light takes 8 minutes to reach us. But from the point of view of the light, the woyage is instantaneous.
Time is being ... ( 4 hours ago by Locust59)
Time is being decieved by a false perception sir. Since there is not a universal perception of time, creating or acting as if there is one would make time an illusion on a universal level. And about the correctness, you got me misinterpreted, I said "OF COURSE NOBODY HAS A CORRECT POINT OF REFERENCE." I still agreed that neither is right universally but both is right depending on perspective. Read carefully what I said, I had no contradictions.
