I would go back in time and remove Hitler. But I've played Command and Conquer enough to know not to.
Got a tip for us?

Just as you can play catch on a train that's going at a constant velocity without knowing that the train is moving (or, more importantly, having to account for the motion), wouldn't a time machine on the earth stay in the same place relative to the earth because it's subject to the same rotational speed around the sun and the same rotation of the earth?I always laughed at the static time machine in the HG Wells film sitting in the same room whilst it travelled back and forward in time. If it was truly static it would be off-world within a few seconds and moving forward 20 years would see the entire Solar System disappear off into the distance
This would also account for the motion of our solar system, galaxy, cluster, supercluster, supercluster complex, etc. through the universe.
If we're not sure, let's find out. Please put a time machine on a train full of flatcars and send it a few seconds into the future to see if it shows up on the same flatcar or a flatcar further behind.
When I'm done with the world, whenever someone asks you who your daddy is, your answers will be, "Abstract".
Even I will be my own daddy.
On second thought, that's kind of gross....
What you said only applies to motion in a straight line. Even if the galaxy were moving, it may be moving in an orbit of some sort. Also, the Earth rotates, so unless you time-travel to the same time (on the clock) but on a future date...

I'm thinking that as gravity is subject to the same laws as the rest of space-time a difference of one second in time will take a light-second for the gravity force between the planet and the machine to catch up. This would lead to the machine slipping out of the planet's/Sun's/Milky Way's gravitational well as it moved further away from its starting temporal point.
That always seem to allow for uncertainty in the expression, and that just won't do.
I wouldn't share it, I would take full advantage of it for myself.
Kind of off topic, there was a show / movie on sci-fi a long time ago and it had time travel, they went back to the time of dinosaurs. They had to stay on the floating walkway and they couldn't bring anything organic back. Needless to say someone did and it affected the current timeline. Anyone know what show or movie that was?

Might be "A Sound of Thunder"?

Have to say I liked the written version more.

It's the sound of Thunder. Here is the full text of the book. It's quite great http://sussexhigh.nbed.nb.ca/jjohnston/summer_school-07/A_Sound_of_Thunder.pdf

someone has been reading asimov's short stories (although that had to do with gravity)
I don't recall having read a story along those lines, but I've read so much Sci-Fi over the years it's entirely possible that I have and now only remember the idea in the story rather than the story itself.
Can you post the name?
Only when the train is moving linearly. Toss the ball when your train goes around a curve. Or play catch on a carousel or a playground merry-go-round some time. It's mind-bending.
I've already invented a time machine. I've gone back and changed everyone's future, though you don't realize it.
In the original time line, Apple went out of business in 1994. But since we're all here, it's clear that my machine worked.

Depends on the scale - you can easily not notice rotation and the effects it brings (such as the Coriolis force).
No, I wouldn't tell people about it.
I think that maybe I already did or will invent time-travel. It seem that I've already used it. Or will use it... I'm not quite sure.
Oddly enough, it involves mirrors.
Me at 16 got to see Me at well, really old.
Really Old Me gave 16 y/o me some profound (and stunningly correct) advice.
Though I took the advice and benefited from it, I really wish that Lottery Numbers were involved.
Still don't trust mirrors,

PS. The advice that has served me so well? "Just Do It!" Works for many, many situations in life.

no, it would be too much for the human race to handle right now. till we achieve world peace and there is no hatred in the world, time travel back in time is not to be allowed. however, future is different. future, ppl can eff up as much as they want.
I Think the negative consequences are overestimated.
Primarily because I think that anyone in possession of such a device were they to take a leap back in time even if they were to make no impact upon that time what so ever I do not think they would return to this universe they would return to a random permutation likely alien to the world they left.
one probably could however travel to many possible futures and then return back to the present, either out of curiosity or to gain possible technological advances.
The only thing I would be worried about were others to gain access to the thing would be that people may irresponsibly utilise technology gained from the future, if they go back to alter their past it's essentially not my problem, and if they're just a tourist in the future then that's again fine by me, if they place any bets upon what they observed or anything like that unless it's something not too far in the future and not prone to being impacted by true quantum randomness. To be honest though I'd welcome the collapse of the gambling industry
In answer, probably not and were I to go somewhere myself, it'd probably be the future assuming that tests sending unique objects to the future and back proved that it was safe and one would not get lost in the multiverse.

You could do that today if you wanted. May as well say you'd go back in time and have a cup of coffee
