But i havent painted it cos i already have it, and no-one else has. So where did it come from?

 

Edit: Does anyone else have any ideas or views on this?

You sent the painting on the 20th day of the month to the 15th day of the month,

so inturn you already have the painting on the 15th day. When you reach the 20th day

if you where to look for yourself, you might find your self going into your time machine sending a painting back to the 15th day.

So now there is two of me? That doesnt make any sense lol

yes it make's perfect sence, because your future self sent it on the 20th, you got the painting on the 15th. And there will be two of you because you went into the past.

I didnt go into the past - i just sent the painting back. Id just carry on living my life as normal after i send the painting back the first time. Id just keep living my life as normal, i wouldnt bump into my future self on the 20th.

You said you did go into the past, as you just said in the past..And because you

went to the past you will bump into your future self if you look!

No - the only thing travelling into the past is the painting and the note. I dont travel through time at all except in the usual way.

The "paradox" occurs because you've broken a physical law and yet assumed the rest still work. Once you have time travel you lose causality, so you can have the painting before you painted it.

Which law have i broken?

 

Can you elaborate on the rest? - I'm not sure i understand

Your right you did say the only thing that your sending using the time machine

is the painting and the note. And now I believe your also right about how life will just go on normally.

 

By Joe! I think you've got it! : )

That's what i thought, but id be glad to hear more from swansont on the matter.

 

Although i should point out again that this isnt something i thought of alone, a physicist from the IoP thought it up. Im merely putting it in the way as a problem with time travel.

Well said!

it isn't a paradox. you are making the events circular again.

 

you go:

1)paint the painting again

2)send it back in time

3)get it

4)1 again, but you don't paint it

 

it is supposed to go:

1)you get it

2)you paint it

3)you send it back in time

 

or

 

1)you don't get it

2)you don't paint it

3)you don't send it back in time

So i get it, then i paint it? How does that make sense? How can i paint something i already have?

it makes perfect sense. you can't send it if you don't paint it.

That's why it's a paradox.

 

Your saying that i receive the painting and then i paint it, but how is it possible to paint the exact same painting im holding in my hand?

it is possible because you haven't painted it yet

So what happened to the painting i found in the time machine?

I believe what Danny is saying is this: Things only occour once in the future, If for example he sends a painting (on the 20th), to him self in the past (to the 15th) then on that day (the 20th) he nolonger has the painting, there is only the one, and that will be the one he gets on the 15th..Then once it is the 20th day of that month. He wont see him self sending the painting in the time machine because the "painting" not "him" went into the past: Hence: there cant be two paintings sharing the same time period in the time line because all chronological events move forward ..

It dosen't seem like a poradox to me. We have choices!

So the painting just disappears?

No. you still have the "same" painting that you got on the 15th from the 20th.

Right, and so if i dont send that painting back, how does me in the past get it?

 

If i dont send the painting back i dont get it on the 15th, if i dont send it back then i 'cant' have it on the 21st. Sounds like a paradox to me...

Well!..The past is the past.

 

Why do you think you cant have it on the 21st?

And did you not say "No - the only thing travelling into the past is the painting and the note. I dont travel through time at all except in the usual way."
