Academia
The flaw in academia is that it tries to teach you what to think , when it should be teaching how to think .

If you haven't learned the tools of critical thinking, researching and presenting empirical evidence you won't function in academia. Select facts to bolster the answer in your back pocket and you'll get found out.

Don't follow leaders, watch the parkin' meters...

So he built a train set. A man stood on the platform with a beam of light shone past him. A train passes the station with a woman on it. As the train approaches the speed of light the beam might be expected to pass by the woman more slowly than seen by the man on the platform. Consistent with Newton but not Maxwell’s constant. Einstein turned the whole thing on its head by saying that the flow of time may not be the same for all observers. Einstein asked can events happen simultaneously? He imagined the man having two bolts of lightening hitting the platform at equal distances either side of him at the same time. That would be simultaneous. Then he put himself in the shoes of the woman on the train moving at close to the speed of light. As the train would be moving towards one strike and away from the other strike, time would elapse between the strikes. Therefore different observers cannot agree simultaneity which suggests that they cannot agree on the flow of time itself, concluding in the fact that there can be no absolute or universal time. So, this lack of simultaneity and the fact that to the man on the platform and the woman on the train the speed of light remains the same will lead to the conclusion that relative to the man on the platform, for the woman on the train time actually runs slower. Do the heavy duty mathematics and E=mc squared comes about.
