What if you can travel back in time???

Going back in time to kill hitler is how the plot line of "command and conquer: red alert" started. Einstien goes back in time to kill hitler and instead of hitler starting WWII, Stalin does. And things are A LOT worse.

If i could go back in time, i would warn myself whats going happen in the future....

Step 1: Wait until the next big lottery.

Step 2: Wait until the numbers have been drawn and write them down.

Step 3: Travel back in time.

Step 4: Give myself the numbers and tell where and when to use them, if not I will come and eat everyone I know.

Step 5: Hope that due to the time paradox the numbers don't get altered.

Given that time space contradiction occurs, Myself from the Past should not meet Myself from the Now, as if MyselfPast met me, MyselfNow should have a memory of it.
For the purpose of a better life, ill get the biggest lottery number and go back in time untill the lottery is not revealed, buy the ticket, and stay in the past untill i get my money then putting it into a NEW bank account registered under my name and ask them to inform me about it in the future, exactly the date when i started travelled back to the past. I will try my fully best to not interact with any human being on my stay in the past, wearing a face mask and heavy clothing will be appropriate with glasses to not let anybody notice me. As i am back to the past, i know where MyselfPast is right at that time so i will not meet him in order to cause a major contradiction that may just end my existance.
Then i would travel back to the Now from where i left, and look in my mailbox ^^

Since this is on serious discussion i would rather take a heavy precaution and think every possible outcomes

The short answer would be to go back and tell myself to study harder.:p

The long answer (may have already been mentioned) is simply that time travel is impossible as time is not a tangible quantity like space. Thus it is impossible to go back in time in the same way it would be impossible to go back in any other measurement. You can not have negative time thus you can not go back in time. Time is effectivley a human concept and is a 'strategy' we use to allow our minds to cope with the events of our lives in a quantifiable manner. No matter what science hypothesises, it is simply ridiculous to believe time can 'travel' any other way but forward.

-sigh- rant end

Changing the past means changing everything that comes with it. You can gain/lose something but either way you changed the present course thus you're not satisfied with what happened to you...

If I only could...

I would change the flow that the system of this current "Parallel" is diving to the spontaneous destruction due to the "Chaos Theory" that man neglected to recognize which result to the unstoppable "Phenom" that will arrive in the dawn of the "End" causing a "Dimensional Rift" and create "Multiple Parallel" causing a massive distortion of "Time Space Continuity" using the ripple of the "Butterfly Effect" one can create a Loss/Gain Future of equivalent result...

WTF am I talking about?!?!

Yes i will change it for something like Lottery Tickets

If I could travel back in time, I would probably go back and change some dipshit choices I made.

Time travel to the past is useless. Should you attempt to time travel to say... the day the first human was born to kill him/her, you would create a loop. You kill him, but that does several things.

1) Human kind no longer exists.
2) The you in the future can not make the travel to your current location.

Ergo, nothing happened. This applies to any other time travel. If you try to do something with hopes to change it, you alter the future so that the you in your time is better/worse off. But because of this, there is no reason for you to time travel.

Good Question.
If it were me.....

1] redo things i did wrong
2] excel greatly in my studies
3] wait till Fakku appears and be the first to sign up
4] save my money from buying useless toys
5] tell people about predictions
6] do things that were not done yet
7] Early exposure to H
8] help people who are in need
9] Tell people of future technology so that the future would be more modern
10] AND MANY MORE!!!

There's 2 things I may do.

A.)Murder everyone with my advanced technology. Motive? Just to see what happens in the future.

B.) Tell myself of the future so that I may be rich.

I would do things that i didn't.
Damn, wish i could see my grandfather now, i miss him.

If I can travel back in time... i will...

1. Tell myself about the world of Hentai. So myself of the past will already be enjoying the benefits of Hentai!

2. And also about this great site. a reliable source of hentai.(if Fakku already existing that time) am i right?!

Time travellers would be everywhere, time and space will fill up, then big bang will re-occur. God will be so mad at the person who pushes that start button on that tim machine.

If possible, I'll go back in time, bring a flame thrower, and make a legend of the "dragon-man who conquered a third of the world and had tons of hot, unadulterated sex with the princesses of all kingdoms. Oh yeah he also killed Hitler."

I would go back to my junior high years and beat the Fucking Hell out of this one guy and also my younger self.

Go into the future and get some very very high tech miniature penny size technology and then go back in time to the medieval era( Or further back) with the high tech interior version of Lich King's Armor with a sharpened high tech interior sword of Frostbourne and see what happens to me from there on. If I'm about to die, transport back and go do something else amusing again.

If I was given the chance to go back in time I'd most likely change some really retarded decisions I've made.

If i could go back in time i would probably do something stupid and screw up the world, so i would go back in time to stop myself from going back in time... wait.
