Discussion Overview

The discussion revolves around the concept of time travel, particularly in the context of Einstein's theory of relativity. Participants explore the implications of traveling at high speeds and how it affects the perception of time, including hypothetical scenarios involving meeting one's future self and the nature of time's passage on Earth.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants propose that traveling very fast through space results in time dilation, where time for the traveler passes more slowly compared to time on Earth.
  • One participant suggests that if a traveler goes 50 years into the future, they would be able to greet their mother, who has aged 50 years, but questions the possibility of greeting their future self.
  • Another participant agrees that the traveler could meet their mother but argues against the idea of meeting their future self, prompting further reflection on the scenario.
  • A humorous comment is made about the idea of talking to oneself after a short duration, indicating a playful take on the concept of time travel.
  • One participant references a video about a man who claims to have met his future self, questioning the validity of such an experience and whether it could be possible.

Areas of Agreement / Disagreement

Participants generally agree on the concept of time dilation as described by Einstein, but there is disagreement regarding the feasibility of meeting one's future self. The discussion remains unresolved, with differing interpretations of time travel scenarios.

Contextual Notes

Participants express uncertainty about the implications of time travel and the nature of time itself, with references to anecdotal experiences and media that may not align with established scientific understanding.

Who May Find This Useful

Individuals interested in theoretical physics, time travel concepts, and the implications of relativity may find this discussion engaging.

Einstein found out that the faster you move trough space, the slower time goes. So if you travel very fast trough space, then 1 hour for you, could be many years on earth.

So let's say you travel very fast, and therefore goes 50 years into the future. Then you are landing on Earth 50 years into the future. Will you then be able to say hello to your mother who have become 50 years older? And would you be able to say hello to yourself as 50 years older?

If so, does this mean that the future already exist today, but time on Earth haven't come that far yet?
(or am I very wrong now? :P )

Correct - although there's nothing special about space, any travel does this. If you fly transatlantic and back you will be a tiny fraction of a second less old than if you had stayed at home

Will you then be able to say hello to your mother who have become 50 years older?
yes
And would you be able to say hello to yourself as 50 years older?
No - think about it !

You can talk to yourself as 1 hour older...but don't let the Psychiatrists see you...XD

Yeah, that couldn't be right :P I would only be an hour older.

But I saw a video about a man who was fixing his shrink, and as he went longer inn to screw, he suddenly was at a beach. There he claimed to have met himself as 50 years older. So he could stand there and talk and shake hands with himself.

Don't know if he speaks the truth or not, but could this really be posible?

here is a link to the video a saw:
