Where will you end up? Empty space?
You'd have to manipulate the whole Universe, not just the Galaxy.

You're 100% correct NavalFC! Sadly though, the only way some people have been able to hold onto their beloved time travel theory and cancel out the paradox (because they desperately want it to be true) is to start talking gibberish on alternate time lines.
Dan Burisch anyone?

At least we are realistic. We aren't the ones inventing ways to prolong a fantasy. Entropy doesn't allow for backward time travel. Alternate realities/time lines are just another unfalsifiable pseudo science. Pure drivel!

You have to realize that we here on earth are part of the universe, time is not some localized phenomenon, its is universal. What we experience as time is the movement of the earth, solar system and the galaxy within space. If everything would stop, time would also.
Earth is moving 30km/s
Sun is moving 220km/s
Galaxy is moving 550km/s
So if you were to travel back one second in time you would need to reverse the movement of the earth by 30km, the sun would need to go back 220km and the galaxy 550km. Then there are all the other stars and planets within the galaxy that would need to be reversed plus other variables we dont know that are connected to the universe expansion and gravitational effects of other galaxies around us.
You must see this is impossible right?

Yep, Einstein and Newton only dealt in fantasies. Nothing they've ever done has been published, studied, or proven...! Theoretical physicists only write kids stories. String theory - forget it! Multi-verse - no way! And what was that other thing? Oh, that's right, the Theory of Relativity. That must've been an episode of Star Trek.

I'm familiar with all the theories you've mentioned yet your subtext would suggest that I can't have if I disagree with your idea of what is or isn't possible in this universe. That's a false assumption.
String Theory, Super String Theory, Theory of Relativity, Brains, Dark Matter, Dark Energy, Black Holes, Quantum Physics, yada yada yada.
Most of these people are getting grants to simply say "Imagine If". None of the science is solid. It's a situation where bad theories require the 'invention' of new theories to plug the gaping holes in the math & logic. Kind of like having to create 11 dimensions to account for 'gravity'.
At least Einstein gave us something observable and measurable. The rest is just poppycock until proven otherwise.
Sure I agree with you that anything is possible given enough time which means we should also prepare to be invaded by an evil armada of Stay Puft marshmallow men from the Sugar Cane Nebula.
What's that I hear you say? "That ain't gonna happen?" "It's not likely!" "The odds against it are unfathomable!"
Hmmmm

Of course it is crazy, we are talking about time travel here, it is something so impossible that its crazy to be speaking of it as a possibility yet. It is simply a sci-fi fantasy that will never come true. The only possible way to do it is the impossible way that would need all the energy in the universe reversed, thats not even debatable at this point.
You suggest a simple time machine that just jumps into another time. How would that work? I would love to hear your theory.

How could you say things like "It is simply a sci-fi fantasy that will never come true" when we're talking about something that might take a million years to figure out? You really think that's out of the realm of possibility? It will NEVER come true. You guys like the words NEVER and IMPOSSIBLE. It's kind of an easy way out.

And suggesting something as unfalsifiable as "in a million years - yada yada yada" isn't taking the easy way out?
At least were sighting valid scientific reasons such as entropy and the astronomical energy requirements to achieve such a thing, if at all possible. In return all we are getting from you is imagination. Imagine this, imagine that, what if - and so on yet the subtext in your posts is riddled with a sense of unwarranted self righteousness.
Sure it's ok to dream and carry on but at the end of the day you must pay homage to our limitations. It is, at the end of the day, what is real in our current context.
Also you use the phrase "are you a Theoretical Physicist?" often yet by your own admission you are are not, therefore it kind of makes the question/argument invalid. Is it ok for you to hold your opinions and not be a physicist, yet not ok for us? Just wondering because you consistently display this attitude.
Also you didn't address how physicists need to do stupid things like create theories with 11 dimensions to make up for what is already a flawed model of physics. Surely a true model would have symmetry and wouldn't require band aids? Therefore would it be safe to assume that everything else that's based on those models may also be false?

Oh it's the Stay Puft Marshmallow guy again, here to add more 'realism'.
You are obviously at odds with the scientific community, questioning their '"flawed model of physics", yet you aren't a physicist either. How did you learn more about physics than a physicist?
So my question/argument is invalid because I'm not a Theoretical Physicist?? What a tough crowd...
And what does "pay homage to our limitations" mean exactly? I'm not sure what our limitations are going to be but apparently you seem to know. We have until the end-of-time to advance so tell me where you see the limitations. I'm curious to know. Thanks.
