"Congratulations on being elected president!"
One of the things we have to brief you on is a highly classified project called Stargate. It started out as theoretical research project ran by DARPA. What it produced was 'portals' to what we believe to be alternate universes.
The project opens a energy gate exactly 2.3 meters. We can sustain the gate stable for about 10 minutes, needing an hour to cycle. The gate was originally developed at Stanford University, since then we have moved it to the USAF base in "Bohome, AZ" You provably know it as "Area 51. The gate machinery itself requires four semi trucks to move it. It also has large power requirements, currently being met by the nuclear power plant at Area 51.
We have identified 31 of what we believe to be alternate earths. We believe the gate establishes a link to it's counterpart location on the alternate earths.
We have not send anyone through the gates yet, but have been able to sample the atmospheres. 1 of them is highly radioactive (we believe as the result of nuclear war), 1 of them has a very high levels of pollution, 3 have levels that are roughly equal to 'our Earth during the 20th and 21st century, which we believe means they support complex industrial societies. Two others have very low levels of pollution which may mean that they are either more advanced (and using 'greener energy') or they are less advanced. One seems to be in an ice age. 24 seem to be relatively virginal.
Our science advisers believe we will encounter human and perhaps 'neanderthal' populations on the other planets. We do not know what the other cultures will be like, as we don't know when the deviations occurred.
We have done nothing but sample atmosphere until we could get an effective quarantine facility in place. In seven days a quarantine facility will be open that will allow us to send either tethered robots or human scouts through the qates. Remote control systems will not work as the gates do not allow 'radio or electromagnetic radiation' through the gate.
Mr President. The Secretary of State wants to address the UN Security council in secret to determine the way ahead. She thinks our first priority should be to meet and establish formal relations with the industrialized worlds, under a UN treaty.
The Secretary of Defense recommends that we send small numbers of Special Forces troops through to what we believe are the virginal planets and conduct reconnaissance. He recommends we identify non-populated planets and claim them for ourselves. He recommends that we very slowly explore establishing relations with the 'industrialized worlds.'
The Secretary of Agriculture and Interior agree with Sec Def.
Currently there are only 30 people (with Top Secret Omega-Epsilon clearances) who know "most of the story." Many people who work at the labs know they are working on quantum physics research.
This is now your decision. How shall we go forward?
(A interesting branch would be you are "Dave Branson (or Bill Gates or some other VERY wealthy corporate persona) what would you do in that case. Do you bring it to any government or the UN or try to keep it a secret.
