The advantage to cricket over baseball is that they have a wicket that the pitcher throws at to strike out the batter whereas in baseball there is an imaginary strikeout zone roughly defined in relation to the batters body.

Oh all knowing one, what graphics card should I buy that has 64mb? Ive been showed the Gefored 4 420ex (or xe?) repeatedly, so Im guessing thats standard. How do you reduce photos with MS paint (step by step) since rabie cant bring himself to devulge his special knowledge in this area (I dont have photoshop yet)? I have more computer Qs, but my brain is drawing a blank, more later.

mixtecRE: Whats the speed of Dark ?
“I have mentioned the event horizon (here and in a previous post about BHs).
The event horizon is the sphere in space around an object that marks a boundary.
As an example there is a similar boundary around Earth and it is determined by the escape velocity of the object.
The Escape velocity for earth is about 11km/s.
If you leave the surface of earth at less than this speed then no matter how high you manage to get you will not escape earths gravity and you will fall back to earth eventually.
Gravity is strongly influenced by distance.”
You cant compare event horizons to escape velocity. Escape velocity is the measured speed of orbit where an object will not fall back to earth and therefore maintain somekind of infine orbit. There is no escape velocity for any object leaving straight up from the surface of the earth, this force can be calculated by in infinate ratio
“If you are 1,000km above the earth then you are 1,000km from the surface on one side… at about 12,000km across you are therefore 13,000km away from all of the earth at 1,000km above one side.
If you crushed the Earth down to the size of a marble the its gravity at 1,000km above one side will be significantly greater. In fact to reduce the Earth to that size will create a black hole.
This takes me back to the event horizon.”
Center of gravity is measured at the center of mass, there would be no dectable difference in the force of gravity if you crushed the earth to the size of a marbel and maintained same altitude form center
And your wrong about the space ship being shrunk and achieving infate mass at light speed. All that would be measured by an observer not the person insde the spaceship.
Someone please look this up and prove Im right.

There was a quote from the Carthaginain General Hannibal Barca (the first military stratigist)who was known for having a good snese of humor and when asked by one of his men about being in a bad situation before a battle, said something like ” and not one of them is named….” refering to the name of the person who was asking. If you can find this quote, Id aprecciate it.

Your wrong SOC, the flashlight in front of a spaceship will function perfectly normal for the person inside the spaceship. Its a person standing stationary (relatively speaking) outside who will see no light emitted from flashlight. Your cannon firing from a mach 5 fighter is not a good example because again were dealing with the atmosphere. In a vacume there would be no reduction at all of the bullets velocity due to the speed of the fighter.
C´mon folks, isnt there anyone here whos studied this in college? Ive never formally studied physicics and only have a general knowledge.

Merlin-
“I was always taught that, as somebody has already pointed out, gravity is a force.”
Its not a force inherent in mass itself, mass bends space, space is causing the force
“A mass is forced by gravity to the Earth.”
Two masses are attracted to oneanother by the inverse of their distance (the earth is merely a mass)
A mass will also be forced to the earth when it has fallen or is seperated from the earth. ie jumping off a building or from an aircraft.
Remember the atmosphere factors into this heavily with objects in relation to the earth, the atmosphere forces objects into simutaneous motion due to friction. An object never actually leaves the force of attraction of the earth. When an object leaves the so called gravitation of the earth, its really just being taken over by a larger more dominant gravitation of the sun. When an object leaves the so called gravitaion of the solar system, its really not leaving anything, it again is just being taken over by the larger overall “gravitation” of the galaxys orbit.
“A mass will accelerate and gain a maximum speed through the air because of the forced applied by gravity.”
Your refering to terminal velocity which is caused by the atmosphere, in a vacume in would continue to accelerate indefinately
“This would mean that gravity is a constant force and a mass travelling aided by gravity would gain a max speed and therefore a constant speed.”
constant in relation to what?
ink-
“So if a man with a torch is travelling at the speed of light past the earth and I’m standing on it watching him switch the torch on – do i see it emit a beam of light? Surely the speed of light is a constant and can never be increased? The light emited by the landing-lights on plane doesn’t travel at: 3×10^8 m/s + a bit, does it? It still travels at the speed of light.”
Yes the speed of light is constant just as the speed of sound is relitively constant at a given altitude. So when your on a train and you hear the sound of a traffic warning bell rise as you approach and fall as you move away, the speed of the sound has not actually changed, but it has changed in relation to you, hence- relativity, get it?

mixtecRE: Stones for engagement rings
You need to read a book called “The illusion of diamonds” by Epstein. The value of diamonds is artificially set by the DeBeers company of south africa/namibia. If your a sucker, youll pay these artificial prices. I am familiar with emeralds, if you want to make a really good deal, youll go to colombia where you can buy them for a fraction of the market price. Remember the two important points to look for is clarity, any sparkeling in the stone is caused by imperfections and is to be avoided. And the darker the green the more valueable the stone. And of course this factors in with the size/weight of the stone.
