Too Speedy For Gravity?

A new analysis suggests that when five different spacecraft flew past Earth several years ago, they gained more speed than can be accounted for by Einstein's theory of gravitation.

Hello Everyone!
I dont want the readers of your statement to be overly concerned about Einstein's theory of gravitation, quite the contrary they should understand that when an object uses a planet gravitational pull to enhance its speed, there is always an upside. In this case its the apex of the trajectory of the object that encounters the gravitational pull of a planet. Most assuredly and dependant on the object and its flight path, the speed at which the object attains will vary and may in fact exceed theoretical assupmtions,or guesses as it where.

Hmm, let me see if memories serves me right the pioneer units both are atomic engines that are propeled via a method that is magnet based so if I am not mistaken that should be at sub light speed at the time they measured their leaving our system, as far as the asteroid chaser craft that is a ion based system it's designed to propel itself based on a uninterrupted source of energy that is continuously running once it's in the void of space because of that it will build up speed as long as the power flow isn't interrupted.
Based on what the level of energy it is capable of reaching in the short term will determine it's time table toward reaching sub-light speed.

It's strange I was under the impression that all the Nasa personal know they are using ion propelsion based engines now a days.

Espeacially the scientists mentioned in this article.

Everyone knows that heat makes things expand. The radar was calibrated based on the OLD diameter of the earth. Clearly global warming has caused the earth to expand, ergo the measured speed was actually lower than reported. In order to help avoid this sort of inaccuracy in the future, I will be riding my bike more frequently in the future, thus driving my SUV less.

If they are propelled or even steered by an engine, it would be extremely hard to keep its speed variation to less than the quoted 10mm/sec (or something).

The odd thing is that all the birds are fast. Sounds like something common is off one part per million - mass of the earth? Rounding error in some constant? truncation of terms in a formula?

It did NOT have an atomic engine it had a nuclar batterie. Any sped below he speed of light IS sub light.

this is only the 2ont time they used an ion engine

I wonder if the solar winds from sun spots can account for the extra boost,the winds vary with the intensity of the spots?
One other idea I had was did the craft come at the earth on the sun facing side,I know that the solar winds are bent around the earth by gravity and move faster as they are compressed around the earths magnetic fields, kind of like water going around a rock in a stream, The water will speed up on some parts and slow down on others, almost like the wing of a airplane.
Also was the moons gravity factored into the study,I'm sure the moon did some pulling itself and maybe helped some with the boost in speed.

According to the article, they haven't eliminated possible errors in their measurements from software, etc.

So all we know so far is the calcuations and actual trajectory don't quite match.

Just wonder if this has something to do with Dark Energy, the energy needed to accelerate the Universe's expansion rate. The numbers in the article show a large relative discrepancy. If these numbers are not the result of software glitches, as mentioned, it could lead us to something very interesting. Also, as mentioned, the rotation of the Earth along with it's warped space-time shell, could be responsible, too. In other words, the increased spacecraft kick could be the result of Earth rotation and not just it's gravity.

It was additional gravitational forces due to an unaccounted mass of Dark Matter (comprised of Dick Cheney, Bush, and Cuntalisa Rice).

It is all quite obvious, but I can see how the science community missed it.

OWED TO THE SPELL CHECKER

I have a spelling checker-
It came with my PC.
In plane lee marks four my revue
Miss steaks aye can knot sea.

Eye ran this poem threw it,
Your sure reel glad two no.
Its vary polished in it's weigh,
My checker tolled me sew.

A checker is a bless sing,
It freeze yew lodes of thyme.
It helps me right awl stiles two reed,
And aides me when aye rime.

To rite with care is quite a feet,
Of witch won should be proud.
And wee mussed dew the best wee can,
Sew flaws are knot aloud.

And now bee cause my spelling
Is checked with such grate flare,
Their are know faults with in my cite,
Of none eye am a wear.

Each frays come posed up on my screen
Eye trussed to be a joule
The checker poured o'er every word
To check sum spelling rule.

That's why aye brake in two averse
By righting wants to pleas.
Sow now ewe sea why aye dew prays
Such soft wear for pea seas!

You guys with your comic book knowledge of future

I think you are already riding up in the air. Probably into the ozone somewhere.

One thing GRAND about "" Theories""?, that they are theories and theoretics's!.

open for change!, along with revisions!.

Wait until you get into deep space out side of this solar system,

real fun out there it is!.

Sailing might be a mandatory curricular[s] activity of all of the Guys and gals[ maybe aliens also} over at NASA and other places involved in the "spaced"!, researches!.

GEE - YOUR Bible must be different than mine because (New Testament | 1 Thessalonians 4:13 - 17)says NOTHING about SPEED - Indeed that passage could as well be talking about hot air balloons!
Beware how you try to twist the scriptures to make false arguments (2 Peter 3:16)
----which they that are unlearned and unstable wrest (twist), as they do also the other scriptures, unto their own destruction.

Bck on topic of SPEED, and with apologies to those who dislike mingling scripture with science (although some of us see no conflict)--
Einstein said that it is not possible to exceed the speed of light, BUT IF IT WERE possible that eighteen inches would equate to a thousand years. Well, in Biblical terms, eighteen inches equates to about a "cubit" (about the length of a man's forearm)- So, here we have a religious text that indicates that Einstein was only wrong in his statemet that it is not possible:(Pearl of Great Price | Abraham 2 Fac.:1)--- One day in Kolob is equal to a thousand years according to the measurement of this earth, which is called by the Egyptians Jah-oh-eh."
(Well, it is not surprising that Einstein may have made a mistake - after all, the rule is "I before E except after C and Einstein got THAT wrong TWICE <snicker>)

Opps! In editing I accidentally deleted the crutial phrase:(Pearl of Great Price | Abraham 2 Fac.:1)--- The measurement according to celestial time, which celestial time signifies one day to a cubit.----
