This article is the latest in a series
on my ideas of Time Travel and Multiple Universes. Here we will put most of
those concepts together and understand how time travel works within this
system.
Background Reminders
Let us review some of the main concepts
we have discussed previously.
1. We have an Orchard of Multiple Universes, which is
very similar to an orchard of apple trees.
2. Like each tree in the orchard, each universe is a
distinct entity. Each universe grows and develops independently.
3. Just as each tree begins from a single seed and
matures, each universe emerges from a single seed (the Big Bang) and matures.
4. In an apple orchard, we can use seeds which came
from one tree. All seeds have nearly identical DNA, therefore all trees which
come from these seeds will be nearly identical. In the same way each “universe
seed” is almost identical. Therefore, each universe, as it matures, will look
very similar to every other universe which matures from similar seeds.
5. There will be variations from one universe to the next.
Just as each mature apple tree will look slightly different, each mature universe
will also look slightly different.
6. Consequently, each mature universe will look very
similar to the others, and yet each mature universe will have slight
variations.
7. Each universe can be planted at different points in absolute
time. In our apple orchard, we can plant one tree every 5 years, over a period
of 100 years. In the same way, we can plant one universe seed every 5 years,
over a period of millions and billions of years.
8. As we look upon such an orchard in 100 years we see
trees of all stages of growth at the same time. At one point in absolute time
we see dozens of trees, each of a different age.
In a similar way, with our universe
orchard, by planting a new universe every 5 years we have a multitude of
different universes, each of a different age. In these type of orchards, we can
compare trees, or universes, at different stages of maturity, yet we can do
this from one distinct point in time.
9. There is a difference between Absolute Time and
Relative Time.
“Absolute Time” is the total time past from the first tree or
universe planted, to the most recent one planted.
“Relative Time” is the difference in
ages between two trees (or two universes). If one tree was planted 20 years
later than another, then the difference in ages will always be 20 years. When
the first tree is 50, the second tree is 30. When the first tree is 100, the
second tree is 80. Such a difference in time will always be the same, while both trees
mature independently. The relative difference in ages between such trees is the “Relative
Time”.
For Universes, the concept of "Relative Time" is similar: the “Relative Time” for universes is the relative time differences
between ages of two universes. As each matures independently, the difference
in ages (the Relative Time) will be the same.
Time Travel Between Trees
We can now begin to understand what Time
Travel means in this system. Let us first look at the concept of Time Travel
between the Trees. In brief, we are able to walk a short distance, seeing
actual trees of a later age, and in that way we are “seeing” possible futures
for our own tree.
Consider our Apple Orchard. Just by
walking a few feet you can “see” the future. Start at any tree. Then walk a few
feet to the next tree, it is 5 years older than your original tree. Walk to the
next tree it is 10 years older than your original tree. Continue to walk and
you will see trees which are older still.
Note that you are not actually walking
forward in time. What you are doing is walking to a tree which was planted
earlier, and which is therefore older than the tree where you started.
Also note that you are not looking at
the same tree exactly as it will be in the future. Rather, you are looking at a
very similar tree, and seeing what that tree looks at that age. Then, by extrapolation,
you can guess that your tree will look almost exactly like that tree, when your
tree reaches that age. In other words, you are looking at real futures of
similar trees, and guessing that your tree will have that same future. It is in
that way in which you are “seeing” the possible future of your tree.
We can also travel to the past in the
same way. Again we start at our tree. Going the other direction we see a tree
that is 5 years younger, and the next tree is 10 years younger, and so on, down
to the tree which has most recently been planted.
Therefore, if you want to know what your
tree might have looked like 20 years ago, you simply walk the row of trees back
to a tree which was planted 20 years earlier. The trees are distinct – it is
not your exact tree – yet both trees are similar enough that you can make the
comparison. You can guess that this tree of “minus 20 years” is pretty much
what your tree looked like 20 years ago.
Time Travel Between Universes
Now we can come to the concept of Time
Travel among the Multiple Universes. Similar to the Apple Orchard above, the
Universe Orchard has a multitude of universes, each planted 5 years apart. In
brief, when you time travel from one universe to another, you are traveling to
a different universe, which is also of a different age. By comparing the two
universes, you can guess the likely future (or likely past) of your own
universe.
Remember that each universe starts from the
same type of universe seed, just planted 5 years later. Over a period of
billions of years, there will be this Orchard of numerous universes.
If we travel upward in space to the next
universe, we will find it to be similar to ours, yet it will be 5 years older
than our own. Compare that universe to ours, and you can guess what our
universe will look like in another 5 years.
Continue upward in space to the next
universe, and the next, and the next…to a thousand universes above. That
universe will be 5,000 years older than our own. Again, compare that universe
to our own, and you can guess what our universe will likely become in 5,000
years.
We can also go the other way: back in
time. Starting again at our universe we go downward to the adjacent universe.
This is 5 years younger than our own. Travel further, the next universe is 10
years younger than our own. Thus, we can travel to any universe in this
direction, and arrive at a universe hundreds, thousands, or millions of years
younger than our own.
Do you want to see what our universe
probably looked like 10 million years ago? Simply travel in space to the
universe that was planted 10 million years before ours. Study it, look around.
Everything you see is probably what our universe looked like when it was that
age.
Thus, when we time travel in this
system, we are: 1) visiting a different universe, which is distinct from our
own, 2) visiting a universe which was started in a different absolute time than
our own, and therefore 3) we can compare universes to see the likely
possibilities of what our universe will be like at that age. This is the basic
process of time travel between universes.
Futures are Similar yet Different
Remember this dual concept: each universe will be similar to the others, yet also different.
It is important to remember that each
universe will be similar, yet different, from our own. Remember that each universe is distinct,
and each will mature in its own way. Therefore the future may not be exact. Yet
each universe comes from the exact same type of “universe seed”, which means
that the great majority of aspects of each universe will be similar.
Thus, when are doing the comparison
between another universe and or own, know that the future of our universe will
very likely be the same as this other universe…and yet it may not actually be that
way.
Sampling Multiple Universes
Also, we have the option of seeing
multiple futures. To do this, you will visit multiple universes.
For example, you want to know what our
universe will be like in approximately 500 years. Therefore you travel to the
universe planted 500 years before ours, and then make the comparison.
Yet, to get more information you travel
to the nearby universes as well. You go to the universes that are 510 years
ahead, and 520 years ahead. You also go the universes that are 490 years ahead
and 480 years ahead. Each of these universes is near the “500 years ahead” time
difference you are looking for. (I refer to these universes with similar ages as “near-in-time
universes”). Yet each one is distinct, and develops independently. Therefore it
is possible for any of these universes you visited to have a different scenario
from the others.
The odds are that most of the universes
you sample, in a close date range, will have the same major aspects. And if
most of the universes have the same specific aspect you are curious about, then you can conclude with high probability that the future of that aspect
of your universe will be the same as seen in those universes you visited.
In other words, by visiting multiple
universes, each near a target date, then you can compare multiple futures, and
conclude with better accuracy what the future of a particular aspect of our
universe will be.
Multiple Different Futures
However, you may find that some
or all of these major aspects vary from one universe to another. Thus, you now
have “multiple different futures”. You then have several possibilities. You know that
this aspect of your universe can become any one of several scenarios you see in
these future universes. This is how you can see “multiple different futures” for the same
general event.
Summary
Time Travel in the Multiple Universe
System is really traveling to a different universe which was begun at a
different moment in absolute time. The relative time difference between any one
universe and another universe will always be the same for those two universes,
while each universe matures independently.
Therefore we can compare “probable
futures” of our universe by examining the actual future of similar universes
which are older than our own. Similarly, we can compare “probable pasts” of our
universe by examining the actual past of similar universes which are younger
than our own.
We can also visit several universes near
a target date, in order to get several possible futures (or several possible
pasts). Where most aspects of these near-in-time universes are identical, we
can be highly certain that those aspects in our universe will be the same.
However, where there are significant differences among those near-in-time
universes, we can see several possible futures (or pasts) for our own universe.
