The Portal

Built by the Bronies with the help of one Doctor Emmett Brown

Purpose


Well, obviously the purpose was to make a bridge from Earth['s universe] to Equestria['s universe], for that, a trans-universal bridge needed to be made and stabilized.

Construction
Following the leak of info from SGC, bronies contemplated trying to build a portal there, after all, the technology seemed to be there and the scientific principle was definitely there. After several years the bronies managed to create a portal, except it was basically just a stargate, to traverse universes, a matter bridge was needed and they simply didn't have enough informastion to make one themselves. Doc on the other hand knew all about that stuff and readily helped.

The Portal is made of a titanium-[90%] aluminum-[7%] naquadah-[3%] alloy, it also featured E-Ink 'chevron' displays, on the off chance they didn't find the right universe

The inner most ring is stationary and has some tungsten in it to protect against the extreme temperatures caused by the other rings, there are also small shield generators to keep radiant heat from reaching anyone crossing over it

The middle ring spins clockwise and is mostly made of titanium and aluminum, energy is mostly stored in this ring

The outer most ring spins counter-clockwise, contains the chevrons and has a titanium-naquadah alloy, the energy from the middle ring is channelled into the outer ring and into the chevrons

In each chevron is a trio military grade 100k watt capacitors, and on each chevron is an E-Ink display to tell what coordinates are being used

Characteristics
This is much more controlled than using a wormhole through a black hole, but so controlled as the quantumn mirror

there isn't an event horizon, giving the inside of the portal a window like look

because there isn't an event horizon there is no unstable vortex

same as the quantumn mirror and matter bridge, it does not take a very large amount of energy to run even though the 'distance' travelled would be unimaginable

Inspiration
I took most of the design Aesthetics from Stargate

Destiny stargates- The whole gate spins, the arches, chevron design

Milky Way stargates- general look, the back, minor chevron design

Pegasus stargates- being digital in nature, silvery, glowing lights

Orlin's Mini-stargate- size and proportions, designed to only go to one destination and the capacitors

I originally wanted it to look more like the Tollan stargate, but decided against.
