Hi,
Science noob here and I have a serious question with regards to two equations and space flight.
E=mc^2 right? So a hot object should be a teensy (overstatement) bit heavier than a cold object sense it has more energy. What if you just heat up some liquid in circulating tube, pump it towards the back of a spacecraft while cooling it with a bunch of radiators and then sending it back to be heated again.
Since there's less mass at the back of the craft it's a net gain.
Where am I wrong because something this simple should have been figured out by now.
