Creating mass from nothing with time travel

AI Thread Summary
The discussion explores a hypothetical scenario where time travel could allow for the creation of infinite mass by repeatedly bringing back objects from the future. The idea involves traveling forward in time, retrieving a mass, and then making subsequent trips to generate additional mass. While the concept is intriguing, it is acknowledged that time travel is not currently possible, rendering the discussion largely theoretical. The mention of the grandfather paradox highlights the complexities and contradictions often associated with time travel theories. Ultimately, the thread was locked due to non-compliance with forum rules regarding speculative discussions.

So I had one idea. Let's say that you have a cube, it's mass is 1kg and you travel forward in time 10 years and bring it back. Now you have two cubes. Then you go forward again, this time 10 years - 1 Planck time into future. Then bring that cube back again. You can repeat this infinite number of times. You just have to go 1 Planck time before last time. You can create infinite mass.

I know this is just stupid because time travel does not exist and discussing this doesn't make sense, but I wanted to share this.
PS - maybe it's not that stupid, people discuss the grandfather's paradox and that is also not at this time possible.

Thread 'Stories about not so soft space fighters'

I wonder how much stories were written, that involve space fighters, and arent so soft as Star wars. I dont think missiles totally make fighter craft obsolate, for example the former cant escort shuttles if one wants to capture a celestial body. I dont insist fighters have to be manned (i enjoyed Enders game about someone control the events for afar) but i also think it isnt totally unjustifiable.

Thread 'Avatar (film): antigravity and unobtanium'

I thought I had discovered a giant plot hole in Avatar universe, but apparently it's based on a faulty notion. So, the anti-gravity effect that lifts whole mountains into the sky is unrelated to the unobtanium deposits? Apparently the value of unobtanium is in its property as a room temperature superconductor, which enables their superluminal drive technology. Unobtanium is found in large deposits underground, which is why they want to mine the ground. OK. So, these mountains - which...

Thread 'Dune: Prophecy, what to read for additional story context?'

So far I've been enjoying the show but I am curious to hear from those a little more knowledgeable of the Dune universe as my knowledge is only of the first Dune book, The 1984 movie, The Sy-fy channel Dune and Children of Dune mini series and the most recent two movies. How much material is it pulling from the Dune books (both the original Frank Herbert and the Brian Herbert books)? If so, what books could fill in some knowledge gaps?
