Time travel will never be possible.

Discussion Overview

The discussion centers around the feasibility of time travel, exploring philosophical and theoretical perspectives on the nature of time, existence, and the implications of time travel on our understanding of the universe. Participants engage with concepts from physics, particularly in relation to theories of relativity and the nature of time itself.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Exploratory

Main Points Raised

  • Some participants argue that time travel is impossible because only the present exists, suggesting that there is no past or future to visit.
  • Others challenge this view by stating that limiting existence to the ability to reach it is incorrect, proposing that conditions for time travel may exist in phenomena like black holes where time and space are distorted.
  • A participant points out that the argument against time travel based on the absence of visitors from the past is flawed, suggesting that time travel could only allow for travel back to the point when a time machine is activated.
  • There is a reference to Einstein's theory of relativity as a basis for the ongoing debate about time travel, indicating that the theoretical framework remains open to interpretation.
  • One participant reiterates the view that there is no past or future, aligning this perspective with the observation of an evolving universe.

Areas of Agreement / Disagreement

Participants express differing views on the possibility of time travel, with no consensus reached. Some maintain that time travel is inherently impossible, while others argue that theoretical frameworks allow for its feasibility under certain conditions.

Contextual Notes

The discussion reflects a range of assumptions about the nature of time and existence, with some participants relying on philosophical interpretations while others reference scientific theories. The implications of these assumptions on the feasibility of time travel remain unresolved.

Simply because there is no past or future to go to. Only the present exists. Or at least that is what I think. If time travel is possible, why do we have no visitors from other times?

Yeah, and your mother wears purple tennis shoes.
 
Limiting the existence of something to the ability to reach it is not correct. If you could prove that we cannot have visitors from other time that would be a solution. According to the present state of theory one can invert time and no law of physics will be broken. Thus the feasibility of time traveling remains open. It does not necessary means that we as humans will be able to travel over time but such conditions may exist in black holes where time and space are distorted. Of course, there of would be little in that to accommodate our transportation needs but we can predict future, though at limited degree, which is perhaps the actual meaning of the concept of time traveling.
 
The old "No Time Traveling Tourists" argument is flawed as well. There is no reason to expect that we should ever be able to travel back in time further than when we first turned on a time machine. It's along the lines of arguing that radio is impossible because nobody heard a radio broadcast before the first radio was turned on.

FYI, google is your friend. A quick google check of "time travel" will net you 1,000,000 answers in seconds including many detailed references to Einstein's theory of Relativity which is now over a hundred years old.

This is my view also. And this view follows from the assumption, well supported by observation, that we are part of an evolving universe.
