〃Okay;〃 Harry said at last。 〃No conclusions are possible。 We have insufficient data。 The question is whether the sphere was responding to something in its immediate environment; or whether it just opened; for reasons of its own。 Wheres Ted?〃
〃Ted left the sphere and went to the flight deck。〃
〃Teds back;〃 Ted said; grinning broadly。 〃And I have some real news。〃
〃So do we;〃 Beth said。
〃It can wait;〃 Ted said。
〃But…〃
〃…I know where this ship went;〃 Ted said excitedly。 〃Ive been analyzing the flight data summaries on the flight deck; ''121'' looking at the star fields; and I know where the black hole is located。〃
〃Ted;〃 Beth said; 〃the sphere opened。〃
〃It did? When?〃
〃A few minutes ago。 Then it closed again。〃
〃What did the monitors show?〃
〃No biological hazard。 It seems to be safe。〃
Ted looked at the screen。 〃Then what the hell are we doing here?〃
Barnes came in。 〃Two…hour rest period is over。 Everybody ready to go back to the ship for a last look?〃
〃Thats putting it mildly;〃 Harry said。
The sphere was polished; silent; closed。 They stood around it and stared at themselves; distorted in reflection。 Nobody spoke。 They just walked around it。
Finally Ted said; 〃I feel like this is an IQ test; and Im flunking。〃
〃You mean like the Davies Message?〃 Harry said。
〃Oh that;〃 Ted said。
Norman knew about the Davies Message。 It was one of the episodes that the SETI promoters wished to forget。 In 1979; there had been a large meeting in Rome of the scientists involved in the Search for Extraterrestrial Intelligence。 Basically; SETI called for a radio astronomy search of the heavens。 Now the scientists were trying to decide what sort of message to search for。
Emerson Davies; a physicist from Cambridge; England; devised a message based on fixed physical constants; such as the wavelength of emitted hydrogen; which were presumably the same throughout the universe。 He arranged these constants in a binary pictorial form。
Because Davies thought this would be exactly the kind of message an alien intelligence might send; he figured it would be easy for the SETI people to figure out。 He distributed his picture to everybody at the conference。
Nobody could figure it out。
When Davies explained it; they all agreed it was a clever ''122'' idea; and a perfect message for extraterrestrials to send。 But the fact remained that none of them had been able to figure out this perfect message。
One of the people who had tried to figure it out; and had failed; was Ted。
〃Well; we didnt try very hard;〃 Ted said。 〃There was a lot going on at the conference。 And we didnt have you there; Harry。〃
〃You just wanted a free trip to Rome;〃 Harry said。
Beth said; 〃Is it my imagination; or have the door markingschanged?〃
Norman looked。 At first glance; the deep grooves appeared the same; but perhaps the pattern was different。 If so; the change was subtle。
〃We can pare it with old videotapes;〃 Barnes said。 〃It looks the same to me;〃 Ted said。 〃Anyway; its metal。 I doubt it could change。〃
〃What we call metal is just a liquid that flows slowly at room temperature;〃 Harry said。 〃Its possible that this metal is changing。〃
〃I doubt it;〃 Ted said。
Barnes said; 〃You guys are supposed to be the experts。 We know this thing can open。 Its been open already。 How do we get it open again?〃
