How do you know its just biological chemistry occuring on a sub molecular level, if you can't prove that molecules even exist, let alone knowing a whole organism called a "human" exists.

Yeah, that is what I was saying, except instead of saying, "But at a time it was the real reality as well," I said "It could definitely be that it was reality while it happened." So basically what we are saying is that the time traveler lived in reality up until the time he traveled, and in...

Yeah, when I put that idea forward I was thinking of having that effect through orbits, thinking I could design it and back up the idea with a design, but I haven't seen a way for that to be possible.

Also here is some fun with time travel. Say you have a man in 2050 who was born in 2008, and he is tired of his current reality and he time travels to 2008. But to be stealthy he has a total makeover so that he doesn't resemble his original self. Before the makeover he waves goodbye to his...

Well, in the case I'm suggesting there wouldn't really have ever been a transport, its just the matter would spontaneously be created in 1967, and the matter (you) would have a memory of a future that never happened (a faulty memory). It might very well be that you manage to not effect events...

Wait, if you could turn off and on gravity (with little enough or no electricity), couldn't you possibly do it? Because you could have less water than oil and a filter, so when the oil reaches the top you could shut off gravity and the oil would retain its velocity and continue rising until it...

Ah, so the pressure is determined by height*density, not weight*density. That makes sense, because say you had this: It obviously wouldn't cause the water in the second tank to gush out.

Do you mean if I had that last design without a filter? Or what if I reincorporate the original design like this (basically there is a very small tube like thing, so it would have to flow upwards due to the fact there is much more pressure from the higher weight of the oil):

How about this design: Or am I misunderstanding how such things work? And in that design, I suppose you wouldn't even need a filter, right?

Well how do you know your brain and body even exist? How do you know anything you see exists, what if its a complete hallucination? In that case free will/self-determination definitely could exist (or at least conscious cannot necessarily be predicted).

Wait, how do you define "change history." Because many people believe you go into a separate universe, and that the universe you were in originally would not change in history (well, at least the history before you did the time travel), and that the new universe would change. edit: Also, I don't...

If there is any movement of the turbine then there is electricity would violate anti-PMM laws. Well, with the filter instead, oil will slip through to the water tank and flow upward and then it reaches the top and falls down, what equilibrium would be reached? Although, again is the fact that...

Well, I guess if we say that you go back to 1967 and create paradox, there could be some justification for the world not splitting into two realities; because basically what happened is that a bunch of matter was created in 1967, that shot some person that most likely would have just happened to...

Wait would it be that the pressure lost from the oil going up the tube would make it less enough it wouldn't flow into the water? You know what scrap that. With advances in nanotechnology, it may be possible to create a filter where the pores are shaped like oil molecules, making it so that only...

I know for a fact this is impossible since it is a perpetual motion machine, but I can't figure out why specifically (besides the fact it is a perpetual motion machine) it is impossible. Say we have two large tanks. One is filled with oil and the other with water. The one with oil has enough...

Where is the option for no aircraft? Does anyone seriously think Greece will ever actually need them?

Worldwide Compassion is the best missile defense system.

I personally think the death star must have had some anti-gravity device that only effected the outside, otherwise they would waste alot of resources trying to overcome gravity's effects, for example all of their ships outside the death star would have to counter the gravity of the death star...

Although I should note, thank you very much for the video because the vast majority of people thought it was just the San Franciscan air that made us see that. Although, knowing San Franciscan air, it might have also expanded the mind of the camera.

A)Well, This really calls for me restating the rules: “Society should be decentralized (to the point where a community is completely self-goverened). The decentralized government must be made of all people able to communicate in the community. These people make decisions by the democratic...
