Nope. Once the ball leaves your hand, there is one significant acceleration force, which is gravity, downwards. There is no such force as "deceleration", just acceleration in a different direction. If by "deceleration" you mean gravity's acceleration downwards, it is constant enough for our purposes today: 9.8 m/s/s).>> ^ForgedReality:

>> ^blackoreb:
Your idea won't work. Once the ball leaves your hand, acceleration on the ball is essentially constant until it hits something. The only variable acceleration will be due to drag and "dependent on environmental influences such as air viscosity, temperature," etc.
The designer can account for your "never-let-go" scenario, as well as the more common "bouncing-around-in-the-back-seat" scenario, by requiring a minimum launch acceleration, followed by a minimum period of constant acceleration, before snapping a picture.
>> ^ForgedReality:
...Seems like it would make more sense to detect DEceleration, as that would facilitate either an upward OR a downward motion, and it wouldn't be reliant on possible bad guesses at when it would stop moving (dependent on environmental influences such as air viscosity, temperature, wind, obstacles in the path, etc)....

Once the ball leaves your hand, there IS no acceleration. In fact, it becomes inverted, as there are no longer any forces acting upon it to create acceleration, and it is now decelerating. Deceleration is not constant, as it reaches a point where it is essentially weightless. This is the point at which it currently seeks to snap the image. If It actually detected when the ball stopped moving, acceleration wouldn't be a factor.

@TheFreak, @Deano, @Hive13:

Technically, there is no place in the universe where one is not affected by gravity. The astronauts on board the International Space Station are also pulled towards the Earth with a force almost as strong as the one we feel here on the ground. What we usually mean when we say "Zero G" is rather "Free Fall" which is what these base jumpers experience to some degree in the same manner as the astronauts, at least at the start before they reach terminal velocity. Although if you want to be pedantic, "weightlessness" is a better term than zero gravity.

@Mazex

Well, where your claim about brainwashed people falls apart is that if Jesus was made up (which no reputed historian would claim), or His resurrection wasn't true, his disciples certainly wouldn't have martyred themselves for that lie. Being direct witnesses of the fact, you can't claim they were brainwashed. So yeah.

I posted the historical reliability of the bible because it shows its not just cooked up, as you tried to claim. It's highly intricate, and I dare say it would be actually be more miraculous for holding up so reliably if it wasnt true. 100 percent historical accuracy is pretty compelling, I think..it indicates that these are honest eye witness accounts we're dealing with.

Here are some interesting science facts that the bible fortold thousands of years before science knew anything about it..pretty good for made up isnt it?

The earth free-floats in space (Job 26:7), affected only by gravity. While other sources declared the earth sat on the back of an elephant or turtle, or was held up by Atlas, the Bible alone states what we now know to be true – “He hangs the earth on nothing.”

Creation is made of particles, indiscernible to our eyes (Hebrews 11:3). Not until the 19th century was it discovered that all visible matter consists of invisible elements.

Oceans contain springs (Job 38:16). The ocean is very deep. Almost all the ocean floor is in total darkness and the pressure there is enormous. It would have been impossible for Job to have explored the "springs of the sea." Until recently, it was thought that oceans were fed only by rivers and rain. Yet in the 1970s, with the help of deep diving research submarines that were constructed to withstand 6,000 pounds-per-square-inch pressure, oceanographers discovered springs on the ocean floors!

There are mountains on the bottom of the ocean floor (Jonah 2:5-6). Only in the last century have we discovered that there are towering mountains and deep trenches in the depths of the sea

Blood is the source of life and health (Leviticus 17:11; 14). Up until 120 years ago, sick people were “bled” and many died as a result (e.g. George Washington). Today we know that healthy blood is necessary to bring life-giving nutrients to every cell in the body. God declared that “the life of the flesh is in the blood” long before science understood its function.

Noble behavior understood (John 15:13; Romans 5:7-8). The Bible and history reveal that countless people have endangered or even sacrificed their lives for another. This reality is completely at odds with Darwin’s theory of the survival of the fittest.

The first three verses of Genesis accurately express all known aspects of the creation (Genesis 1:1-3). Science expresses the universe in terms of: time, space, matter, and energy. In Genesis chapter one we read: “In the beginning (time) God created the heavens (space) and the earth (matter)…Then God said, “Let there be light (energy).” No other creation account agrees with the observable evidence.

The universe had a beginning (Genesis 1:1; Hebrews 1:10-12). Starting with the studies of Albert Einstein in the early 1900s and continuing today, science has confirmed the biblical view that the universe had a beginning. When the Bible was written most people believed the universe was eternal. Science has proven them wrong, but the Bible correct.

Light can be divided (Job 38:24). Sir Isaac Newton studied light and discovered that white light is made of seven colors, which can be “parted” and then recombined. Science confirmed this four centuries ago – God declared this four millennia ago!

Ocean currents anticipated (Psalm 8:8). Three thousand years ago the Bible described the “paths of the seas.” In the 19th century Matthew Maury – the father of oceanography – after reading Psalm 8, researched and discovered ocean currents that follow specific paths through the seas! Utilizing Maury’s data, marine navigators have since reduced by many days the time required to traverse the seas.

Incalculable number of stars (Jeremiah 33:22). At a time when less than 5,000 stars were visible to the human eye, God stated that the stars of heaven were innumerable. Not until the 17th century did Galileo glimpse the immensity of our universe with his new telescope. Today, astronomers estimate that there are ten thousand billion trillion stars – that’s a 1 followed by 25 zeros! Yet, as the Bible states, scientists admit this number may be woefully inadequate.

The number of stars, though vast, are finite (Isaiah 40:26). Although man is unable to calculate the exact number of stars, we now know their number is finite. Of course God knew this all along – “He counts the number of the stars; He calls them all by name” (Psalm 147:4). What an awesome God!

The fact that God once flooded the earth (the Noahic Flood) would be denied (2 Peter 3:5-6). There is a mass of fossil evidence to prove this fact, yet it is flatly ignored by most of the scientific world because it was God’s judgment on man’s wickedness.

The continents were created as one large land mass (Genesis 1:9-10). Many geologists agree there is strong evidence that the earth was originally one super continent – just as the Bible said way back in Genesis.

Life begins at fertilization (Jeremiah 1:5). God declares that He knew us before we were born. The biblical penalty for murdering an unborn child was death (Exodus 21:22-23). Today, it is an irrefutable biological fact that the fertilized egg is truly an entire human being. Nothing will be added to the first cell except nutrition and oxygen.

God has created all mankind from one blood (Acts 17:26; Genesis 5). Today researchers have discovered that we have all descended from one gene pool. For example, a 1995 study of a section of Y chromosomes from 38 men from different ethnic groups around the world was consistent with the biblical teaching that we all come from one man (Adam)

Origin of the major language groups explained (Genesis 11). After the rebellion at Babel, God scattered the people by confounding the one language into many languages. Evolution teaches that we all evolved from a common ancestor, yet offers no mechanism to explain the origin of the thousands of diverse languages in existence today.

Origin of the different “races” explained (Genesis 11). As Noah’s descendants migrated around the world after Babel, each language group developed distinct features based on environment and genetic variation. Those with a genetic makeup suitable to their new environment survived to reproduce. Over time, certain traits (such as dark skin color for those closer to the equator) dominated. Genesis alone offers a reasonable answer to the origin of the races and languages.

Air has weight (Job 28:25). It was once thought that air was weightless. Yet 4,000 years ago Job declared that God established “a weight for the wind.” In recent years, meteorologists have calculated that the average thunderstorm holds thousands of tons of rain. To carry this load, air must have mass.

Medical quarantine instituted (Leviticus 13:45-46; Numbers 5:1-4). Long before man understood the principles of quarantine, God commanded the Israelites to isolate those with a contagious disease until cured.

Circumcision on the eighth day is ideal (Genesis 17:12; Leviticus 12:3; Luke 1:59). Medical science has discovered that the blood clotting chemical prothrombin peaks in a newborn on the eighth day. This is therefore the safest day to circumcise a baby. How did Moses know?!

Our ancestors were not primitive (Genesis 4:20-22; Job 8:8-10; 12:12). Archeologists have discovered that our ancestors mined, had metallurgical factories, created air-conditioned buildings, designed musical instruments, studied the stars, and much more. This evidence directly contradicts the theory of evolution, but agrees completely with God’s Word.

A seed must die to produce new life (1 Corinthians 15:36-38). Jesus said, “unless a grain of wheat falls into the ground and dies, it remains alone; but if it dies, it produces much grain.” (John 12:24). In this verse is remarkable confirmation of two of the fundamental concepts in biology: 1) Cells arise only from existing cells. 2) A grain must die to produce more grain. The fallen seed is surrounded by supporting cells from the old body. These supporting cells “give their lives” to provide nourishment to the inner kernel. Once planted, this inner kernel germinates resulting in much grain

Olive oil and wine useful on wounds (Luke 10:34). Jesus told of a Samaritan man, who when he came upon a wounded traveler, he bandaged him – pouring upon his wounds olive oil and wine. Today we know that wine contains ethyl alcohol and traces of methyl alcohol. Both are good disinfectants. Olive oil is also a good disinfectant, as well as a skin moisturizer, protector, and soothing lotion. This is common knowledge to us today. However, did you know that during the Middle Ages and right up till the early 20th century, millions died because they did not know to treat and protect open wounds?

The Pleiades and Orion star clusters described (Job 38:31). The Pleiades star cluster is gravitationally bound, while the Orion star cluster is loose and disintegrating because the gravity of the cluster is not enough to bind the group together. 4,000 years ago God asked Job, "Can you bind the cluster of the Pleiades, or loose the belt of Orion?" Yet, it is only recently that we realized that the Pleiades is gravitationally bound, but Orion's stars are flying apart.

Soil conservation (Leviticus 23:22). Not only was the land to lay fallow every seventh year, but God also instructed farmers to leave the gleanings when reaping their fields, and not to reap the corners (sides) of their fields. This served several purposes: 1) Vital soil minerals would be maintained. 2) The hedge row would limit wind erosion. 3) The poor could eat the gleanings. Today, approximately four billion metric tons of soil are lost from U.S. crop lands each year. Much of this soil depletion could be avoided if God’s commands were followed.

Animals do not have a conscience (Psalm 32:9). A parrot can be taught to swear and blaspheme, yet never feel conviction. Many animals steal, but they do not experience guilt. If man evolved from animals, where did our conscience come from? The Bible explains that man alone was created as a moral being in God’s image.

I take issue with the voice over. He says that the 'automatic reflex action is almost completely lost' in weightlessness. Which is bullshit, they haven't lost the reflex, they just can't do it, you can see them try, but they over correct and spin around etc.

Stupid voice over man.

I'm sure we'll see something like this, just as soon as someone invents that weightless, infinite-capacity battery that's just around the corner.

I won't even begin to discuss just how anxious -I- am to see all those moronic drivers -flying-. Or the lack of safety features, or cargo capacity, or visibility (laying facedown isn't a really good way to see what's ahead). Frankly, this is more appropriate to an episode of the Jetsons than it is to anything NASA should be doing.

I was more impressed with his air-time than any implied sport or successful landings.

I have a personal obsession with flight and/or weightlessness, and if watching someone else do some pretty insane jumps allows me to live vicariously through your antics of weightlessness and defiance of gravity (It's the Law!), then more power to you.

I get the same feeling from watching astronauts, skateboarders on halfpipes, bmx jumps, motocross jumps, watching planes/helis take off/land, watching monster trucks leap over stacks of junked cars, watching parkour, gymnastics, etc.
And with such an extensive, readily available list from which to pull examples, I can't be the only one that feels this way.

It's all about the air-time man... the air-time...
The landing is just a crafty way of avoiding injury after the fun stuff is over.

Let's get one thing out of the way first: If the Earth should somehow be compressed enough to form a black hole, its mass would stay exactly the same. What makes black holes so spectacular is not their huge mass, but the fact that their mass is compressed into a very small area. This again means that you are able to get dangerously close to the center of gravity. This is not possible here at Earth, since there is a lot of rock and magma preventing you from getting that close.

But even if you were able to burrow yourself down to the center of the earth, you still wouldn't be swallowed by a black hole. This is because the amount of Earth dragging you downwards would be much less, and all of the rock above you would be dragging you upwards. You would in fact be weightless, since all the parts of the Earth would be dragging you in opposing directions. You would still be crushed because of the high pressure, but that is another story.

All massive objects have a property called the escape velocity, which is the speed you need to escape its gravitational well starting from its surface. And this property would increase if you compressed the Earth, since its surface would then come closer to its center of gravity. If you compressed it to a radius of 8mm, this velocity would excede the speed of light, which means that nothing, not even light, could escape.

This is the definition of a black hole.

It was just so close to the car in front that it was running very slow air (relative to the car). Without the downforce from the body cresting the hill at that speed probably got eh car close to weightless and the faster air above the car sucked it up. The rest is down to Newton.

I don't think the aerodynamics were out for an open track, but you'd think they'd take slipstreaming into account too!

Ha ha ha ha ha! That's gonna come out of her paycheck. Working in space has got to be the most amazing experience ever. They say the weightlessness diving provides is close to how zero G feels, but nowhere in the ocean can you find truly unlimited visibility!
