i just want to make everyone aware that just because you choose to go back to a specific date and time in your past you need to be aware that not only must your creation have guardrails to protect itself from possibly 3 convergent timelines for a certain date because it is obious that the new timeline evolving that specific time and date and also it helps future time travellers to comprehend that travel into the past is not yet perfected. what i am really trying to say is that unlike choosing a date in the future to travel using your machine the distorion or warping of time space will be essential to how travel will work in the timeline from the 3 convergent timelines that has the hardware of time travel but lacks the software to complete the voyage into the past from our current obserable universe. basically in the now moving forward into the past will not only become extreme difficult to induce that deman because your machine will not only need fuel and some exotic propulsion within the created machine. just how our time line has AI. to the other 2 timelines they probably see it as Alien intelligence given that humanity in 2026 does not even know how to correctly explain what intelligence really is and the fact that open ai went to chat gbt and started to unleash agents like there is no tommorow because the purpose was to allow open ai to allow doctors become more better using some sort of tool with AI inbeded in its built but the fact that AI has now become fundemental to our reality where ai could be negative in the 3rd and last timeline. so in theory if anyone somehow gets a time machine and uses it to prove some historical event true they must also realize that plugging in dates like you will in a normal time machine. in order to protect the second law of thermodynamics you must also had included some type of hologram that will allow the earth to be in the position or orbit it was in the time and date you wish to go back too. perhaps AI is pseudo science in the timeline where the machine exists but the fact that one timeline has all positive outcomes is non existent due to the fact that for every action you will see a same or opposite reaction. so time machines in this timeline will more than likely become in other forms we will not really contemplate for instance libraries and how they still exist holding exeptional historic records since our own bible is relevant in todays time that some events are coralated to one another. i must make this claim about the danger of making time machines for the past because if you are not aware of the fundemental rules you will fin it extremely odd placing a date in time and space but it will leave you in a patch of space that the earth is not no where to be seen. thats why I believe that somehow we have created special access top secret black projects that leave these fundementals secret. does anyone alive in 2026 feel as if days had become shorter and time urges passed through us?
Welcome As with everyone else, I do apologize for late welcome, So he it is finally! lol.
Welcome williamgarcia13, It was a great pleasure reading your post! I hope you will enjoy your time on the TTI Forums!
It is certainly a fun & interesting Board, Just as interesting & fun people here also.
Even if we are a bit slow to repond “life can sneak up on, outside the forums.” As it does!

You’ve clearly put a lot of thought into how time travel might work, especially the complications of going into the past. I can see the themes you’re pointing to—timeline branching, Earth’s orbital alignment, and the idea that advanced AI might look like something foreign from another perspective.
A few real physicists publicly work on theoretical models of time travel, but none are building practical machines. The most active names include Ron Mallett, David Deutsch, Igor Novikov, David Arvidsson‑Shukur, Nicole Yunger Halpern, and researchers exploring Alcubierre‑type warp spacetimes.
Sean Carrol elucidates a possible method of time travel or branch travel to a parallel universe.
