There are no major revelations discovered or huge first-time pieces of information discovered, but it hit home hard the fact that we are connected. We can try to ignore the fact that our energies affect each other, but the hard cold truth is that they do.
In one part in the film, Tom Shadyac (the guy on the quest) is sitting in front a bowl of yogurt. The yogurt is hooked up to all of these various cords that register the energy in the yogurt. Let's all be clear. Yogurt doesn't have feelings.
So, the scientist would ask Tom questions that would evoke a negative/positive response (like, hey, Tom, have you talked to your agent lately? or hey, Tom have you talked to your lawyer lately?). Tom wouldn't say anything necessarily in response, but the machine registering the energy from the yogurt would move - recognizing a change in the energy.
It was powerful. It was crazy to see how the yogurt picked up the energy that Tom was feeling.
How did that happen?
We are connected. We feel what each other feels. We hurt when another hurts and we can't explain it. It's why we hate being around people who bum us out and we love being around people who have positive energy. It's why our heart physically hurts when someone else is in pain.
