A Acceleration If an object held near the surface of the earth is released, it will fall and accelerate, or pick up speed, as it descends. This acceleration is caused by gravity, the force of attraction between the object and the earth. The force of gravity on an object is also called the object’s weight. This force depends on the object’s mass, or the amount of matter in the object. The weight of an object is equal to the mass of the object multiplied by the acceleration due to gravity.
A bowling ball that weighs 16 lb is actually being pulled toward the earth with a force of 16 lb. In the metric system, the bowling ball is pulled toward the earth with a force of 71 newtons (a metric unit of force abbreviated N). The bowling ball also pulls on the earth with a force of 16 lb (71 N), but the earth is so massive that it does not move appreciably. In order to hold the bowling ball up and keep it from falling, a person must exert an upward force of 16 lb (71 N) on the ball. This upward force acts to oppose the 16 lb (71 N) downward weight force, leaving a total force of zero. The total force on an object determines the object’s acceleration.
If the pull of gravity is the only force acting on an object, then all objects, regardless of their weight, size, or shape, will accelerate in the same manner. At the same place on the earth, the 16 lb (71 N) bowling ball and a 500 lb (2200 N) boulder will fall with the same rate of acceleration. As each second passes, each object will increase its downward speed by about 9.8 m/sec (32 ft/sec), resulting in an acceleration of 9.8 m/sec/sec (32 ft/sec/sec). In principle, a rock and a feather both would fall with this acceleration if there were no other forces acting. In practice, however, air exerts a significant upward force on the falling feather and makes it fall more slowly.
The mass of an object does not change as it is moved from place to place, but the acceleration due to gravity, and therefore the object’s weight, will change because the strength of the earth’s gravitational pull is not the same everywhere. The earth’s pull and the acceleration due to gravity decrease as an object moves farther away from the center of the earth. At an altitude of 4000 miles (6400 km) above the earth’s surface, for instance, the bowling ball would weigh only about 4 lb (18 N). Because of the reduced weight force, the rate of acceleration of the bowling ball at that altitude would be only one quarter of the acceleration rate at the surface of the earth. The pull of grav

Bohm’s Quantum Alternative 2/2
This is theory, and mostly correct but not completely. A Large Hadron Collider will create proof of what I am saying in the very near future. According to relativity, a singularity is fundamentally a boundary where space-time ends. Therefore nothing should be able to break away from it, but this notion is wrong because singularities are not permissible by quantum gravity. The center of a black hole is extraordinarily dense, but it’s not so impenetrable that it traps everything. Quantum space- time doesn’t end at a singularity, information can escape. This is how I travel in time. This is a brief description of how such post are wrong. I’m from the United States in the year 2037 and I am seeking parts for our defense systems that are no longer made because of ecologic reasons. The reason I am choosing to communicate has many reasons. My message is simple time has meaning only as we give it meaning and that when a person dies means that they have no use any longer for time, yet they still are. It is what we do here that counts this is the only moment that we have is HERE & NOW. I will offer proof of those who ask. Please remember I am much like your Astropeople were in the past. I know about how time travel and how the mechanisms work on an elementary level, much like how the Astropeople of the past knew the basic understanding of the devices or vehicles they used. I use a Mass & Gravity Microsingularities Manipulation Device (MGMMD) or as you would know it a Time Machine (that is a very simple idea that has long since been disposed of) and have some understanding of its operation. If you would like to ask me questions I will try to answer in the short period that I have in this HERE and NOW. I’m very busy on my operations and duties and I will reply as I am able.
I wish you many Blessings

Hi Caleb,
I have always been interested in time travel and I know that it is not possible in the present, but I’ve always said that if someone claimed to create a time machine, then I would do it for free as I don’t like this day and age. But anyway, I’m just wondering, if an event was prevented from occuring let’s say for example the terrorist attacks in September 11th 2001 and you’d go back to that particular day and year and prevented it from occuring, would it alter the present as it would in the movie “back to the future” and if you returned to the present, the world trade center would be still standing?, if so, I know exactly when I would like to go back to, April 11th 2004 7:00pm as I want to stop a heartbreaking event that has already happened early this year and the reason I said that date so that I can take every precaution necessary to prevent this unfortunate event from occuring and I would know exactly what to do. Call me paranoid, but I just have this feeling that time was tampered with going back to between July and September 2007. I know that I can’t go back, but I just wanted to ask you these questions about preventing unfortunate events that have occured.
Thank you

“Quantum space- time doesn’t end at a singularity, information can escape. This is how I travel in time. This is a brief description of how such post are wrong.”
Well…I guess poor grammar, bad punctuation and a basic ignorance and misunderstanding of physics would lead one to such a post. Nice try.

These present day theories are interesting at best but antiquated.
Here’s the adjustments so that, under the right configuration, time travel can be a practical working theory but for that person(s) that is able to finish the last panel of calculations understand and abide by the rules of time traveling and manipulation(s). Once the sheet of glass has a crack it’s next to impossible to go back and fix it.
Ok here we go.
To understand the basics of time travel you need to re-learn a few basics and throw out the rest and think in multiple-levels all at once for it to make sense. I’m still working on the last panel of calculations but plan on withholding, on purpose, for obvious reasons.
My descriptions are at absolute basics, on purpose but NOT designed to insult or belittle in any form.
Our dimension- We are not in the 3rd d, as we have been taught, but instead in the 4th d and from there on in many dimensions and alternatives. Let’s lay out the basics first. 1st d= say heighth. 2nd= heighth plus width. 3rd= h+w+depth. These are all traversable directions/existances, in a basic sense. 4th d= h+w+d+?. ?=time. So we are h+w+d+time (4 dimensions. h+w+d+t).
Time- Imagine time as a current of energy. Let’s compare it to electricity flowing from positive to negative (here’s a mental picture. Imagine a bolt of lightning traveling from point A to point B. Slow it down for viewing practicality). Now let’s say that everything we know exists in and IS this bolt. Now let’s say that everything already exists; the before, the now, the future events. This bolt may actually exist for a nano-second in a mega-universe scale, aka. spark, but to us it goes on forever. Now divide this bolt up into micro-slices much like a film strip (kindergarden-like I know but all the same) while numbering each strip with a unique identifying number much like the decay number assigned to radiation(s) (for basic sake let’s say 1,2,3,4,5…).
Next Dimension(s)- So the 4th is best described as a walled/separated cascade of events. 1/2/3/4/5/…. Each being built/existance in zero time. 1st d then 2nd d then 3rd then 4th then 5th…1st d then 2nd d then 3rd d…The 5th dimension (existance quality) adds a new direction ability, rising above these so called walls (imagine a maze that you climb to the tops of the walls separating you from the mazes’ restrictions. You now have the ability to travers over these). {note: this is where my new panel of calculations start}. The 6th (h+w+d+t+5th+?) adds new traversing abilities, possibly dimensional, possibly null-space/time before it’s existance. aka. dimension A to B to C to etc.
Infinite alternatives- Imagine that this bolt isn’t one smooth line of energy but sub-bolts extending in multiple directions and extending into many dimensions. With each decision that we make there are an infinite possiblities/alternatives as with each one of those are infinite alternatives and so on.
Existance of the one before- You walk thru your life BEING in any given point in one place. Let’s say, you in bed. You exist in that place for X time. You get out of bed. In the 5th d you still exist in that bed AND you exist when you got out of bed AND you exist in the path that you take next (say, crossing the room and walking downstairs and making coffee). You already are in front of the coffee machine and you already are in the shower, etc, etc. See where I’m going with this? Ok, one more example. You go into an old house. Think of all the people that lived/traveled/existed in and thru this house in the past but think of all of their everyday/everysecond, for as old as the house is, ALL AT ONCE, in the right now. THIS is the 5th d.
Traveling time isn’t trying to beat the speed of light but to access the next dimension above us allowing for unrestricted directions (aka no walls).
Now comes the question, how do we get to say Dec 4th 1004? Then back again? THIS is where the fun begins my friends.
(Author note: I feel that with any given information on this subject and if the studies on ancient artifacts are true; especially the one about a ancient statue of what appears to be the spaceshuttle that dates way back when (example) and going on the possible need to find a new home for mankind in some distant/near future for any given need (let’s face it folks. We’re moving TOO slow in changing the damage we inflicted on this planet to save it/us in time. Present calculations show that we’re only moving the curve a few degrees on the world graft. Proper changes has to demonstrate an increase of at least 15% in the next 15 yrs and increase from there over the next 50 yrs to reverse are present course). One possible explanation may be that WE had to leave our planet to continue and the closest home that we could access NOW was in the deep past as our very presence would cause nominal changes/damage to our future(s).)
