I think it goes back to one of the various quantum theories before that.
When the unuverse consisted of overlapping proabblity waves, of which
only one collapses into an actual real observable event.
String theory is as full of holse as a string bag actually.
Please Sport Pilot, this is all well understood stuff. Talk about the
Universe moving is simply nonsense. Movement must be relative to
something else that the object can be measured against. Your
hypothetical and unlikely multiverses and mirror verses are not such
objects as there simply is no physical connection between our universe
and these hypothetical objects.
Likewise your statement that the universe has a fixed center is
nonsense. The universe is known to be roughly 12 billion years old.
This is an experimental fact based on a variety of physical
measurements. We can look out with scopes like Hubble nearly that far
in any direction and see exactly the same thing regardless of
direction. There is good reason to believe that the universe has a
diameter of at least 90 billion light years, also based on a
combination of physical measurements together with theoretical
calculations. It may be vastly larger. Including infinite. There is
simply no way at all to tell if we happen to be someplace close to the
center or billions of light years from the center. Statistically the
later is far more probable. Thus talking about a fixed center is
simply nonsense. No matter how much we learn and no matter how long
intellegent life exists this question will never be possible to
I will take one last attempt at explaining why your "slowly falling
object from space" can not exist. I will only use high school
Let us assume for the moment that at a particular moment an object is
at a point 100 miles above the earth and traveling at 2000 miles per
hour west to east. Further this object is over the equator. Under
these conditions it would seem to be standing still to a person
directly under it as this is the speed at which the earth rotates at
the equator. At the particular moment of examination the object is
neither going up nor down. It is simply suspended at a point over the
earth at that exact moment.
Now, what does high school physics tell us the object was doing one
second before the moment defined above? Simple. It tells us the
object was several feet lower and travelling up. How about a minute
before the moment definded above? High school physics tells us it was
a lot of feet below where it is now and with a lot of vertical
velocity. If you want exact numbers any high school physics student
can calculate them for you.
Now, rather then having the object simply be going 2000 miles per hour
west to east lets slowly speed it up and see where it was a moment
before it arrived at the stated point. Again, basic physics tells us
it was lower until it finally reaches a west to east speed equal to
its orbital velocity which as I recall is some 16,000 miles per hour
at this altitude. At this speed it will maintain its height above
earth until atmospheric drag slows it enough to cause it to crash.
This establishes a lower limit on the speed of any object from space
entering earths atmosphere. It MUST be going at least 16,000 miles
per hour. If it is going any less it did not come from space. It
came from the earth itself somehow.
Now, this assumes that somehow the earth managed to trap a passing
object in a stable earth orbit. This almost never happens. Most of
the time an object from space enters earths atmosphere at well above
orbital velocity. As the escape velocity from earth is about 26,000
miles per hour this is the speed that most objects from space will
have when they hit the earths atmosphere. Makes no difference what
direction they come from this is how fast they will be going when they
hit our atmosphere.
Plain old Newtonian physics demands the above. You do not need
anything fancy like quantum mechanics or relativity to do these
calculations. The NASA guys did them with slide rules 50 years ago
and got things into orbit and back.
This fellow says that the speed can vary from 12 to 70 km/s:
"Earth orbital speed is 28.8km/s, orbital escape speed is the square root of two
times this, 42.1km/s, and surface escape speed is 11.2km/s. The slowest meteor
would be one that just catches up with the earth then "falls", 11.2 km/s. Don't
expect anything less than 12km/s. But a retrograde body in parabolic orbit (the
maximum speed for a body at a distance of 1AU that is a member of the solar
system) might close with earth at a speed of 42.1+28.8=70.9km/s plus the 11.2
"fall" for a total of (total^2=70.9^2+11.2^2) 72km/s. So we expect a range of
12-70km/s with the slower ones in the evening ("catch up" and prograde, no
retrograde) and fast ones in the morning where we do the catching-up and collect
all the retrograde rocks."
Yes, I read every word , very inspiring. I'm going to have to really
get into this type of thing. I'm really burnt out with my job and have
been looking for something to get into till I get my other robot thing
in production. Plus, we have already been working on the cameras for
an even different avenue. Its perfect and all are related in what I
want to do. When I get up in the morning to do R&D and such I'm
dancing in the shower and ready to go. When its time to go to the
gazillionth pool I loathe every step of the way in comparison.
Wish I still had all those weed trimmer motors that I gave away to the
uncle-in-law that made kiddy Harleys out of. I had 6 to 8 of them ,
now I don't have a one just to look at right now.
Ah, but you miss the point. There is no space outside of the universe. The
universe is it, at least in this reality. Other realities? Now that is a
horse of a different color. Where have I heard that before? 8>)
I am ripping this off from Martin Moleski's prior post.
"The big bang was not a bomb that went off in the center of the
universe and hurled matter out into a preexisting void. Rather it was
explosion of space itself that happened everywhere, similar to the way
expansion of a balloon happens everywhere on the surface.
"The difference between the expansion of space and the expansion in
space may seem subtle but has important consequences for the size of
universe, the rate at which galaxies move apart, the type of
astronomers can make, and the nature of the accelerating expansion that
the universe now seems to be undergoing" (38).
So if there is expansion and it is sililar to the surface of a ballon,
then there are limits to the universe. So that logically means that
there has to be an outside of the universe. Unlike those who are
universally upside down.
