Where is all the Anti-Matter?

Just as Einstein's own Relativity Theory led Einstein to reject time, Feynman’s Sum over Histories theory led him to describe time simply as a direction in space. Feynman’s theory states that the probability of an event is determined by summing together all the possible histories of that event. For example, for a particle moving from point A to B we imagine the particle traveling every possible path, curved paths, oscillating paths, squiggly paths, even backward in time and forward in time paths. Each path has an amplitude, and when summed the vast majority of all these amplitudes add up to zero, and all that remains is the comparably few histories that abide by the laws and forces of nature. Sum over histories indicates the direction of our ordinary clock time is simply a path in space which is more probable than the more exotic directions time might have taken otherwise.

wrong - progression in time is effected by both gravity and relative velocity. This has been proven threw experiment and practical application. Time – as Einstein said is a dimension. It’s just a question as to whether it is a single dimension (front/back) as most perceive, or a complete set of 3 dimensions as space is.

If you´re going to try quoting Einstein, please do everyone a favour and actually read what HE said rather than what various muppets claims he said?


No, progression in time is not affected by gravity or velocity. Perception of time is.
And yes that includes time dilation and various other effects. That is the locally perceived time getting messed with.

Those/that being affected will not notice it all, while point of view will determine how others perceive it.

Let´s do a little thought experiment shall we?
No realism what so ever, just for show.

A spaceship travels 100 years in one direction at such speed that their internal time to the crew is just 1 year.
Then they do the same trip in the other direction.
If TIME was really affected they will now have been gone from the point of departure for 2 years.

Me, i would say they have been gone 200 years.

What about you?

This is one of those things where you have to go with the majority of observers.

So while your hypothetical astronauts (lets say its a large ship with a crew of 1000) have observed the passing of 24 months the rest of the human race has experienced the whole 2 century's.

So the majority wins and 200 years have past.

Of course this becomes a lot more difficult in the far future when the majority of the human race is zipping between the stars on planet sized ships, at different velocities, experiencing different time, rarely coming into contact with each other . Its likely then that an external point of reference (eg Sol,assuming that humanity remembers its origins, or the galactic core) will be universal for humanity.

Which brings me to two questions I'm not qualified to even probably ask, but I think some of the much smarter people on this forum may be able to answer.

What percentage of C would you need to be travelling to achieve 99% time dilation?

And secondly considering the huge speed that the solar system must be travelling in its galactic orbit (approx 1/1300 C according to Wiki), what is the time dilation effect between us and the centre of the galaxy?

You missed the point though. If time itself was really affected, then they WOULD return after 2 years. Which of course we already know from empiric experiments, isn´t what happens. What happens is that any internal timekeeping device affected by speed or gravity, is slowed down.

"So the majority wins and 200 years have past."

Fun way of saying it.

I hate having these thoughts as I'm trying to sleep, its past 2am here, and I've had to restart my Laptop to get this down

But its just struck me that in the entire Universe there can be only one point from where to gain a true observation of the passage of time, and that is the exact point where everything started some 14 billion (ish) years ago, the centre of the big bang.

Logically, Ctia(?)'s theory would mean that Satan being given the bums rush is actually the big bang.

The Universe isn't a democracy. There is no "majority rule". Both are right. It is both, 24 months and 200 years as the travelers changed both their velocity in space and time and returned to the planet at a different point in time. If time were a "figment of the imagination" and didn’t really exist then you couldn’t alter it & there wouldn’t be a “time dilation”.

Maybe you could start by attributing a quote to the person who actually wrote it?

And then you´re saying that they return after both 2 and 200 years? Wow, lovely copout attempt there. Doesn´t work, since noone is likely to believe that those travellers are going to split in two parts and then somehow return at different times despite doing the same travelling.

Who said anything about "figment of the imagination"? Noone but you.

In fact, that is the exact opposite of what i´ve stated, so either you should change the quote to whomever you´re really ranting at or you need to be a bit luckier with your thinking.

The point I was trying to make (probably badly) was that the observed and experienced time for most of the human race would of been 200 years so that when the space travellers returned they would have to expect that 200 and not 2 years had passed.
