Just a little hand held remote  and jump in

I loved that show.... 

I missed the end of it to know how the series closed tho... I ought to go see about buying it one of these days.

Oh but you CAN...  That is the one thing people forget.

IF you can Warp Space so that Point A (where you are now) and Point B (where you want to be at the opposite end of the galaxy) a simple FART is all you need to cover that distance in an instant



Now I would assume that you would need a lot of electricity to power those gravity generators to jump that far (Which is why Star Trek still requires time to get around... they do it in smaller hops) But still... simply fold space to a point where Point A and Point be are 'touching' in the next dimension and you can literally step through

You can easily do this at home...  buy a small toy rocket... get a vacuum cleaner to suck out almost all the air in a container and ignite the toy rocket. I guarantee it will work   

But you don't need a rocket and you don't need electricity .... 

Or any 'brute force' for that matter.

It's far simpler than that .... 

Somma will know about this.

Just involves a little 'Dialogue' through a 'Video Interface'.

You may find some of the ancients used mechanical devices which were hand held and had a small 'hand crank'
was used to provide the Strobe function which Rotate a piece of Polaroid glass over a static piece.

Poor quality glass with a polarised grain will do this.

Just need some Light passing through it (often just sunlight.    )

The rest was done by a Geometric based Dialogue, with a little script within the same little box
with the Strobe.

Very mechanical based Optical Computers.

Now you are talking .... You just may be closer to it than you can imagine ...

But what if you dial up the wrong dimension by mistake?
you might end up somewhere you don't want to be?

Now that is Intelligent ....

Check out what's lurking at the 'target Location' 1st !   

Very, Very Wise. 

There's More to SG1 than perhaps others realise.

Thought I was being observant there for a moment.

Greetings:

Perhaps better to be an 'observant' than to be an 'obfuscator'   

Happy Thanksgivings

From what I could see in Wikipedia, and although that's a subject I do not really know, I don't think you can compare the free expansion of a gas to the expansion resulting from the a chemical reaction like mixing hydrogen with oxygen.

A chemical reaction producing gas IS an expansion of gas. 

[The Matrix Traveller]

2 'Components' are required in a 'thermal converter' such as in a 'Internal combustion Engine'.

A Fuel & Oxygen to provide the heat source (Oxidisation of the fuel, a chemical reaction = Heat.)

The Other Component .... an inert gas which expands after being heat by the oxidising fuel.

The expanding gas acts on the inner walls of the Exhaust Cone.

'For every action, there is an opposite and Equal reaction'.

IF ONLY Fuel and Oxygen is used It won't Work !   

The Inert Gas is required for EXPANSION to take place.


That's right the rocket is 'Farting' !

About the level of Tech. reached through the human Species.   


A little help from our friends, would be a more successful way of reaching the moon, using a little better Tech.
than by creating a large 'Fart'.   

[ArMaP]

A chemical reaction producing gas IS an expansion of gas. 

If it's producing then it's not a specific amount of gas expanding, and I think that's what that "free expansion" principle is about, the expansion of a specific amount of gas into a bigger volume than the one it was occupying before.

[ArMaP]

The Other Component .... an inert gas which expands after being heat by the oxidising fuel.

Does that mean that a rocket with oxygen and hydrogen doesn't work in a vacuum?

[The Matrix Traveller]

By accessing the Program 'Stack' involving our experience, and inserting a 'branch' instruction.   


Branch: (computer science)

A branch is an instruction in a computer program that may, when executed by a computer,
cause the computer to begin execution of a different instruction sequence.

Branch (or branching, branched) may also refer to the act of beginning execution of a different
instruction sequence due to executing a branch instruction. A branch instruction can be either
an unconditional branch, which always results in branching, or a conditional branch, which may
or may not cause branching depending on some condition.

When executing (or "running") a program, a computer will fetch and execute instructions
in sequence (in their order of appearance in the program) until it encounters a branch instruction.

If the instruction is an unconditional branch, or it is conditional and the condition is satisfied,
the computer will branch (fetch its next instruction from a different instruction sequence)
as specified by the branch instruction. However, if the branch instruction is conditional
and the condition is not satisfied, the computer will not branch; instead, it will continue executing
the current instruction sequence, beginning with the instruction that follows the conditional branch instruction.

A little more 'Technical approach' than 'Farting'...

A rocket engine is basically another form of 'Thermal Converter'

But works a little different than piston engines and turbine engines, working on this principle
and do not need to push against anything other than their exhaust cones.

They work on the principle of ejecting mass at high velocities.

But you can't cross Galaxies in minutes though the application of a mechanical Fart !   

Still this is the principle of their operation...

But this does NOT mean the human Primate, used such 'Tech' to get to the Moon.

Perhaps they had a little help from their friends ?   

I think the rocket graphic is partially correct. I think it's more accurate to say the rocket is pushed away from its exhaust cone IF the exhaust in turn has something to "push" against, e.g., a dense atmosphere, immovable solid (wall), etc. Rockets don't push against themselves, so to speak. Also, the exhaust isn't ejected; it merely expands out. Newton's Third Law applies just fine to solid objects but gases are a funny thing.

For example, a bullet is ejected from a gun by the force of the expanding gases within the chamber, with the body of the gun pushed in the opposite direction (recoil). The gas acts upon--ejects--the bullet and the remaining gas in the chamber continues to expand out of the gun barrel after the bullet has been ejected from the barrel, but the gas isn't itself ejected.

A rocket engine is akin to a gun barrel w/o the bullet. The gases formed from the chemical reaction of the rocket propellant chemicals are not ejected out the nose cone because something else isn't acting upon them to push them out, like a bullet from a gun.

The exhaust molecules merely expand out. This expansion is the force; the exhaust is not acted upon. As far as I can see, rockets need a medium to propel through.

I think an analogy would be a dolphin moving its flukes to propel itself through water. The Third Law applies well here re the movement of the flukes against the water. However, if the dolphin propels itself out of the water into the air it can wave its flukes all it wants but it won't propel itself through the air. Yes, I know the atmosphere is a medium. However, even if Earth's atmosphere above the water were somehow suddenly switched to a zero-G environment it still wouldn't be dense enough for the dolphin to propel itself; its "fluke engine" isn't designed for this.

I think the dolphin can no more propel itself in such an environment any more than a rocket in space can propel itself merely by blowing exhaust gases out the nose cone. Their actions both need something external to react (move) against, at which point the Third Law of Motion kicks in. That is to say a rocket (or dolphin) moving is an indirect reaction; the direct (real) reaction here is the resistance encountered when molecules of dense rocket exhaust are blown against reasonably dense molecules comprising the atmosphere (or flukes moving against a sufficiently dense medium like water). In the case of the rocket the exhaust expands out at such speed and volume that the surrounding atmosphere cannot absorb the exhaust fast enough. Thus we have a situation akin to a gun being fired: rocket exhuast as the gun powder gasses expanding in a confined area, rocket body as the gun recoiling, and the dense atmosphere on the other end as the bullet providing sufficient impediment to the flow of expanding gasses.

Perhaps a better analogy is a propeller engine on an airplane or boat in water. The plane/boat moving when the propellers are spinning is an indirect reaction and only happens when the direct reaction takes place: air/water molecules encountering resistance when pushed against other air/water molecules of sufficient density.

A plane or boat with a running propeller engine will not move in the vacuum of space and I think for the same reasons neither will a rocket in the same environment.
