Sounds like a time bomb waiting to go off

... well it gets a 'tick' from me 
Id prefer the numbers for next weekscould i have the winning numbers for last weeks lottery
You have all gone cuckoo
Is this deja vous
I have a time machine in the garage. It's got two wheels and pedals and when I want to travel into the future I ride it round the block. 
Unfortunately it only goes forwards in time so I can't help you with those lottery numbers. The best I can do is to get the results a split picosecond before everybody else.
PS: There's no point trying to build a backwards travelling time machine because it will self-destruct before you've finished making it.

I just love the time travel paradox, which is as follows...
You travel backwards in time and kill your father, thus you will not be born.
Which in turn means, as you were not born, you can not now travel into the past to kill your father.
As you did not kill your father, you will now be born.
You can now travel backwards in time to kill your father......
Got that Trazor.... I think. Roughcaster.

It gets worse. You don't have to commit murder; you just have to stop yourself from building the machine in the first place! It's exactly this kind of paradox which dictates that any backward travelling time machine will destroy itself. You can get round this problem if you come out so far away in space that you cannot get back to your start position before you went in. That is to say, if you want to go back thirty years you will have to emerge more than thirty light-years away.
But before you set about designing your time machine you should ask a very fundamental question: Does the past still exist?
It's not immediately obvious that there is anything to go back to. 
Information can travel into the future. Matter can travel into the future. As far as I know, neither has ever gone back to the past.Space cat wrote
Does the past still exist?
I'm no expert on these matters , but from what I understood, what we see in the night sky, ie the stars, is something that happened many many years ago.
Again I am lead to believe that many of the stars that we now see no longer exist.
Does that mean the past still exists?

This is a good example of how information can travel into the future. It doesn't follow that the source of the information is still there. Indeed, you said it yourself:
My question "Does the past still exist?" is not so easily answered. Time and space are very different. We can move freely in space. We can go back to somewhere we've been before with a reasonable expectation that it will still be there.
We can go into the future, even though it doesn't exist yet, because it will be created while we are in our time machines (or on our bicycles) but what about the past? It is reasonable to believe that the future doesn't exist yet because, if it did, how could we change it? The tricky question is this: As we create the future, do we simultaneously destroy the present?
And while you're puzzling over that one, I have a question:

I vaguely remember something about this. One of the consequences was that nobody could come back from our future unless they had already got there from our past. Can anybody explain the reasoning behind this?
