good question man, one of the first i am really interested in the answer to

Helios that reached 150,000 mph. The Helios, which holds the record for fastest manmade object, was a series of two spacecraft launched in the mid-1970s to study the Sun. Both probes were developed through cooperation between the US and West Germany with scientists from both nations providing experiments and NASA providing the launch vehicle and booster. Helios 1 was launched in December 1974 and Helios 2 in January 1976, both reaching the Sun within about three months.

I believe it would be the space shuttle at the speeds it moves at but if your talking about whats the fastest thing we've propelled and is very small would be small subatomic particles in the massive hadron collider which they've gotten them up to speeds 99.99% the speed of light.

but the sub-atomic particles are not man made...

Well you got me there I admit its not man made but it was propelled by man I didn't think to much on this but yes technically not manmade

the LHC uses 7 Tara Electron Volts (TeV) which is the charge of an electron times voltage, its a unit of energy, 7 TeV is a huge amount of energy. the mass of a proton is 1.67*10^-27 KG or 938.27Mev/C^2 (another unit of mass)

using the relativistic kinetic energy equation E=MC^2((gamma) - 1) we get 7 = (938.27Mev/C^2)C^2(gamma -1) ... 7Tev = 938.27MeV(gamma - 1) 7462.69=gamma -1 gamma = 7463 (aprox) gamma = 1/sqrt(1-v^2/c^2) using more algebra...

we find it gets so close to the speed of light you cant get a good decimal number

WOW nice apparently you did your homework lol I was just remembering what I had heard on a science show and it also stated that its impossible in the normal sense for matter to travel at the speed of light because the instant it did it would gain infinite mass.

i took a modern physics class, we had to calculate all this stuff, this was actually the easy stuff, when we got to wave functions things where not so fun...

Technically, the LHC doesn't move and the particles are not manmade, so that doesn't really count.

but a proton can be made by man... and has

if nothing else the anti protons going the other way are man made

i would argue that although the proton is not man man, it goes that fast because of man.

however voyager I at 3.602 AU/year or 10,604.3661 miles per hour

I thought we also shot man made particles. "On 30 March 2010, the first planned collisions took place between two 3.5 TeV beams, which set a new world record for the highest-energy man-made particle collisions" -Wikipedia

True but I still can fall under the category because its being propelled by man made technology.

@tsilb, Techically they are man made, the partials are created in laboratory conditions this needs to be done for control. They may take the atoms from common sources, but they have to be stripped of electrons to create a positive atom so it can be propelled.

bad news what? what are you commenting on?

(Jun 11 '10 at 23:52) thrashintosh thrashintosh's gravatar image

it has been brought to my attention that in my previous answer a proton is not a man made particle, although it can be man made. and the anti protons that are going the other way are man made...

if you still choose not to accept my answer i offer an alturnitive

Voyager 1 is moving at 3.602 AU/year or 10,604.3661 miles per hour

The Lockheed SR-71 Blackbird is to date, the fastest airplane ever to streak across the sky.

the electromagnetic rail gun, or rail gun for short. Using a magnetic field powered by electricity, a rail gun can accelerate a projectile up to 52,493 feet (16,000 meters) per second ... rail guns can hit a target ~250 miles away in six minutes.

Note: Speeds would be faster used/fired in the vacuum of outer space?!

Beam velocity. The particles "fired" by a PBW will travel at nearly the speed of light (186,000 miles per second). The advantage of such a high-velocity beam is that computing the aim point for a moving target is greatly simplified. The effect of this extremely high velocity is essentially to fix a target, even if the target attempts evasive action. For example, if the weapon were required to shoot at a reentry vehicle (RV) some 50 kilometers distant and traveling at the high speed of 20,000 feet per second, the RV would travel only about 5 feet from the time the weapon fired until it was struck by the beam. It is this aspect of PBWs that makes feasible the task of "shooting a bullet with a bullet," as the ABM targeting problem is sometimes characterized.

The Particle Beam fired from a Particle Beam Weapon

"... Cyclotron particle accelerators, linear particle accelerators, and synchroton particle acclerators can accelerate positively charged hydrogen ions until their velocity approaches the speed of light, and each individual ion has a kinetic energy range of 100 MeV to 1000 MeV or more. Then the resulting high energy protons can capture electrons from electron emitter electrodes, and be thus electrically neutralized. This creates an electrically neutral beam of high energy hydrogen atoms, that can proceed in a straight line at near the speed of light to smash into its target and damage it.

The pulsed particle beam emitted by such a weapon may contain up to 1 gigajoule of kinetic energy or more. > The speed of a beam approaching that of light (300,000 km/sec) in combination with the energy created by the weapon would negate any realistic means of defending a target against the beam. Target hardening through shielding or materials selection would be impractical or ineffective [1], especially if the beam could be maintained at full power and precisely focused on the target.[2] ..."

The ultimate Torch Light would be great and the fastest thing.

As well as lasers.
