About your using portals to create infinite energy from throwing into them something that'll constantly fall through them, I always thought about a problem with that:<br>Stuff fall down (towards Earth for example) because of gravitational waves the Earth creates and these waves travel from it and attract anything they touch. Now, if you create 2 portals perfectly vertically from one another and throw and object into them that'll go through the top side of the bottom portal and out of the bottom side of the top portal, maybe the gravitational waves Earth creates which need to "meet" and interact with whatever you throw into the portals to make them fall down, will actually pass through the bottom side of the bottom portal and out of the top side of the top portal, therefore not going between them and not "meeting" and interacting with anything between them and because of that what you've thrown between the portals won't fall down (or even go up) and possibly just stay in place and therefore you wouldn't be able to create infinite energy from it.<br>Of course, all of this is assuming the portals work from both of their sides and gravitational waves interact with them. If either (and also of course if both) of these assumptions ain't true then what you said might work because the gravitational waves of Earth would like, you could say, "ignore" the portals and still affect whatever is between them,(reply>), @tempusitc Jesus, why are you taking this personal?<br>This is just a stupid science fiction thought experiment.<br>I mean, we don't even have anything that resembles teleportation<br><br>I mean, you didn't even give an explanation for why I'm wrong.<br><br>EDIT: when I said "stupid thought experiment", I didn't mean stupid in a bad way, I just wanted to clarify that it's no big deal, that's all,(reply>), This is absolutely not how gravity works.<br><br>Actually, even if all of your assumptions were true (including your false interpretation of gravity), I can guarantee the object would still fall between the portals just fine.<br><br>Whatever "problem" you think would occur that prevents it from falling is definitely just a simple misunderstanding on your part.
