you would have never existed in your present state so you would naturally combust the moment you killed yourself because you changed the fabric of time

The most popular theories are, you would either cease to exist, as the above answer suggests, or you would simply continue in an alternate timeline from the moment you killed your original self.
For instance, if on September 01st 2017 you went back to July 31st 2017. You visited your own house and saw yourself as you were at the end of July & you killed the July version of yourself.
The September version of you would continue into August and beyond BUT [unless you repeated everything exactly as you originally did] it would be a different timeline from the one you remembered. You'd be the only one aware of it being different.
well what would happen if it was a major eruption and if it was even bigger like then one back in 79 AD then a lot more destruction would happen towns would be whipped out, people would probably die (if they didn't have warning or did not evacuate in time) and it would just be chaos for them.
All the water falls back down to the ground.
an earthquake happens
Never... but i guess if you think it can happen it will be today because they would have traveled back into time there for the technology is here now .... i say they traveled back into time because the future is what you make it and if you skip it to get to it then nothing has happen so there would be no future...
it would just back up and affect every one (12 yrs old)
nothing
You would die
you would be captured and killed e.g shot in the back , gased , or electucuted with other bodys aroung you.
You would risk killing yourself if you tried that. See a doctor if the pain is that bad.
Supposing that you found a way to travel back in time and killed your past self, there may or may not be significant repercussions. Firstly, one must consider the concept of time travel. Time travel in itself is a isolated experience. If you traveled back in time and changed the world's course of events, when you came back to the future, the only person who would know of the changes would be you since you were the only person to have experienced an original and alternate reality. This concept serves as the basis for the next assumption; if you traveled back in time and killed your past self, 1. it would have different effects depending on how early you killed yourself, and 2. would effectively erase your future self. If you killed yourself as a baby, or very early into your life, it would have less repercussions because you would not have as many connections with other people. If you killed yourself later in life, it would appear to have been a murder since the time difference would contribute to you looking dissimilar to your younger self. When you kill yourself, theoretically, you would die and then disappear because you would have erased your existence. ............................................................................................................................. I guess you wouldn't be alive today??? P.S. How would you even get to the past? This is an example of a paradox. They sound almost sensible but with a little thought you can see they are ridiculous, self contradictory and just go around in circles in most cases. If you went back in time and killed yourself then there would be no one to go back in time to kill you so it could not happen. I dont think It is possible for a human to travel back in time.WHY?Because if your future self did not exist in that time it so is not possible for you to exist in that time-space reality, because you never existed then.You traveled in the past and your past self never experienced your future self in the past so therefore it would not be possible.And if you did it would probably rupture Time-Space reality. ----------------------------------------------------------------------------------------------------- My answer, nothing would happen to the you from the future. This is because it's impossible for you to just disappear. It violates the laws of physics. The moment you killed yourself in the past, you rewrite the following years. Say that you stop a man from committing suicide in 2009. Then later, in 2010, you travel back to 2008 and kill yourself. The man you would have saved in 2009 actually commits suicide. Now, what happens to you, however, is a bit more complicated. You (The You from the future) will still exist after you kill the you in the past. The reason, the moment you travel back in time, the timeline you know is rewritten to compensate for your actions. However, you from the future is an exception. Since you had the good fortune of being in the past during the events, you will not be rewritten along with the rest of the timeline. There isn't a split in timelines, just the rewriting of one. And somewhere along the years that follow, a very lonely time-traveler that shouldn't exist does.
He was executed by the guillotine.
If you were to go back in time and kill your parents, it would create a paradox because if your parents were killed before you were born, you would not exist to go back in time in the first place. This type of scenario is often presented in theoretical physics and is known as the grandfather paradox, where altering events in the past can lead to contradictions.
No one would have because you can't go back in time. But if you could then there grandparents would be dead and the one who killed them wouldn't exist.
More than likely it would become a back and forth thing since he could do the same. Another answer: The Time Machine will cease to exist, you would never heard about the time machine and never gone back in time. Simple as that.
Its just like the movies. But some movies go even further and they talk about their parents or ancestors getting killed and you and your family would never be alive here in the future. So that is a yes to this question you will DIE!
it would pee back on you
If you dropped a hamster on its back it would go into shock.
