Adventures in time and space... Part 1

Following the apparent success of the time machine in scientific tests (Max sticking his hand in it), we have concluded that time travel is both safe and not unsafe. Indeed, over the last hour - at least, the last hour for you - Max and I have travelled to several historical events; the sacking of Rome, Max's failed first marriage to Anne of Cleves, the sacking of Rome again, (where we didn't see ourselves) and our local Woolworths store back before it closed down. These trips have all been a roving success: we even bought a lawn-chair from Woolworths, and a rampaging barbarian from Rome.
 However, my longstanding fear of damaging the space-time continuum appears to have been worth it's longstandingness, as rips in space have appeared across the living room, upsetting the goldfish and scaring my visiting grandmother, who dropped her tea. Determined not to let a drop of tea go unavenged, Max and I have launched war on Space and Time, intent on destroying the tyrannical rule of the laws of physics. We've already given Newton a good kicking...

We have seen the ends of time...

The toaster worked, providing both burned bread and a vision of the future. Terrified, dragged into the void, we have seen all that is, and was, and will ever be. We have seen the beginning and the end of time. The Alpha and the Omega. And bears. We saw a lot of bears.
 Travelling to the depths of time, Max and I skipped yesterday, transporting ourselves to today, Tuesday. Later, we might go to the shops. I'm out of butter, and toast - even if it has travelled the length and breadth of time - is still rather dry on its own.
 So far, the space-time continuum is holding up fine...

Toaster Troubles

I took another look at the toaster. Max had been right to fetch me from the desert; it was well and truly buggered. Knowing we couldn't go back to the electronics store after Max first insulted then embarrassed himself in front of the Korean workforce, I decided I would try to repair the kitchen appliance. Dragging the broken husk into my basement workshop, which has just appeared from nowhere to meet the requirements of this story, I got to work. Max, watching over my shoulder, offered occasional gasps of shock or fear when appropriate.
 After about 2 hours, we stood back to appreciate my work. Lacking basic electronics skills as I do had made the task somewhat difficult. However, I think I may have accidently made the world's first working time machine. I've already sent Max back in time a week, to steal my toaster from my home before he broke it.
 I wonder what effect all of this will have on the space-time continuum?

Actually, I'd have to be pretty heavy for this to work...

I took another glance out the window. Yes, there was definitely someone hiding behind my tool shed. Normally, I would ignore such things - they happened often enough, and it was unusual for the lurker to do me any serious damage. However, as I casually watched, I caught sight of the man's face, and there was something eerily familiar about it. Slipping my stab vest on under a jacket, I went outside to investigate.

"Hello?"
There was no reply. There was however, a faint squeal as the man retreated further into the tree's shadow. I was not put on, and crouched down. I stretched out my hand to offer the man some bird seed, in case he was nervous. After a moment, he emerged. Shock overcame me as I looked at him, and I dropped the bird seed all over the lawn. I must remember to tidy it up before it takes root and grows birds.
It was now no surprise why the man before me was familiar - It was me! Sure, I looked a few minutes older, and worry had spread across my handsome face, but it was certainly me! Still, I had to be certain.
"Are you me?" I asked. It seemed a good, if somewhat bland, way of discovering the truth.
"Yes," He replied. "I'm from the future. But... [And here he looked really worried] We shouldn't meet! If two of us exist at the same time, the space-time continuum..."
He trailed off here, whimpering slightly.
"But... Where did you come from?" I asked. Again, boring but straight to the point.
"In two minutes, you'll fall through a time vortex in your kitchen sink. You'll land over the wall, about 5 minutes ago. Quick! Go away. I can already feel the fabric of reality tearing!"
I have messed with the space-time continuum before though, and it doesn't worry me. Obviously, I'm not worried. I think I might do the dishes in fact.
