mononaut(@mononautical):There are only two possible futures: 1. A time machine is built, or 2. New physics are discovered that invalidate the theory of general relativity. According to our entire corpus of knowledge in physics, time machines are possible. Your position can be "these won't be built for a very long time due to energy costs/engineering challenges/economic incentives". It cannot be "these will never be built". Holding the latter position is equivalent to saying "general relativity is wrong". Start with "they aren't coming soon" if you want to argue against the future of time machines. Or if you have proof that they are impossible, please apply for your Nobel prize below 👇.
