"A commonly ignored obstacle to time travel is the simple fact that the universe can only hold so much matter. This is commonly referred to as the "Bucket Factor" by our engineers.
Imagine zat zee universe is a bucket. zis bucket is full of water to zee brim. Zuppose now that a time traveller from zee future arrives in zis universe. Pretend zat your fist is zee time traveller. Plunge your fist into zee bucket. Water spills from zee bucket. You have just filled the universe with more mass zan it can zupport. You have just exploded zee universe. Zat is not good.

And what of the universe zat the time traveller has just left? Zere is now less mass in that universe zan zere should be. Zee inevitable conclusion is zat zuch an action would cause and immediate black hole zat would swallow zee entire universe. Zat is not good, either. "

What i am thinking is that if time and space are actually the same (spacetime) wouldnt it just be the same as relocating material in spacetime rather than inserting more into space. In the end there is the same amount of material in spacetime it has just moved on the 4th dimension.

In other words the universe wouldnt explode.

I read a wonderful book called "A hole in the bucket" By Mr &amp; Mrs Lee King.

I think you have read the same book.

I think the universe will expand for eternity. No matter how much matter you put in it.

I say this because i think the universe is like a giant lung it can take in air and expand and also contract alowing matter to come and go as it pleases.

Your body was created from an atom and grows into a big mass and then when you have finished with it it returns back to a atom with a different composion.

so my conclustion to your statment is "there is no bucket holding water that can over fill".

The universe will continue for eternity and the matter in it will re invent it self the same as you come up with ideas.

Please excuse any spelling mistakes i mayu makes.
