There was now only blackness, with nothing but the past-flashing of a coloured signal light to relieve the gloom. The air was full of a rushing sound.
Gaal leaned forward against deceleration then and the taxi popped out of the tunnel and descended to ground level once more.
The Luxor Hotel, said the driver, unnecessarily. He helped Gaal with his baggage, accepted a tenth-credit tip with a business-like air, picked up a waiting passenger, and was rising again.
In all this, from the moment of debarkation, there had been no glimpse of sky.

Its urbanization, progressing steadily, had finally reached the ultimate. All the land surface of Trantor, 75,000,000 square miles in extent, was a single city. The population, at its height, was well in excess of forty billions. This enormous population was devoted almost entirely to the administrative necessities of Empire, and found themselves all to few for the complications of the task. (It is to be remembered that the impossibility of proper administration of the Galactic Empire under the uninspired leadership of the later Emperors was a considerable factor in the Fall.) Daily, fleets of ships in the tens of thousands brought the produce of twenty agricultural worlds to the dinner tables of Trantor
Its dependence upon the outer worlds for food and, indeed, for all necessities of life, made Trantor increasingly vulnerable to conquest by siege. In the last millennium of the Empire, the monotonously numerous revolts made Emperor after Emperor conscious of this, and Imperial policy became little more than the protection of Trantors delicate jugular vein
ENCYCLOPEDIA GALACTICA
Gaal was not certain whether the sun shone, or, for that matter, whether it was day or night. He was ashamed to ask. All the planet seemed to live beneath metal. The meal of which he had just partaken had been labelled luncheon, but there were many planets which lived a standard time-scale that took no account of the perhaps inconvenient alteration of day and night. The rate of planetary turnings differed, and he did not know that of Trantor.
At first, he had eagerly followed the signs to the Sun Room and found it but a chamber for basking in artificial radiation. He lingered a moment or two, then returned to the Luxors main lobby.
He said to the room clerk, Where can I buy a ticket for a planetary tour?
Right here.
When will it start?
You just missed it. Another one tomorrow. Buy a ticket now and well reserve a place for you.
Oh. Tomorrow would be too late. He would have to be at the University tomorrow. He said, There wouldnt be an observation tower or something? I mean, in the open air.
Sure! Sell you a ticket for that, if you want. Better let me check if its raining or not. He closed a contact at his elbow and read the flowing letters that raced across a frosted screen. Gaal read with him.
The room clerk said, Good weather. Come to think of it, I do believe its the dry season now. He added, conversationally, I dont
bother with the outside myself. The last time I was in the open was three years ago. You see it once, you know, and thats all there is to it heres your ticket. Special elevator in the rear. Its marked To the Tower. Just take it.
The elevator was of the new sort that ran by gravitic repulsion. Gaal entered and others flowed in behind him. The operator closed a contact. For a moment, Gaal felt suspended in space as gravity switched to zero, and then he had weight again in small measure as the elevator accelerated upward. Deceleration followed and his feet left the floor. He squawked against his will.
The operator called out, Tuck your feet under the railing. Cant you read the sign?
The others had done so. They were smiling at him as he madly and vainly tried to clamber back down the wall. Their shoes pressed upward against the chromium of the railings that stretched across the floor in parallels set two feet apart. He had noticed those railings on entering and had ignored them.
Then a hand reached out and pulled him down.
He gasped his thanks as the elevator came to a halt.
He stepped out upon an open terrace bathed in a white brilliance that hurt his eyes. The man, whose helping hand he had just now been the recipient of, was immediately behind him.
The man said, kindly, Plenty of seats.
Gaal closed his mouth, he had been gaping, and said, It certainly seems so. He started for them automatically, then stopped.
He said, If you dont mind, Ill just stop a moment at the railing. I I want to look a bit.
The man waved him on, good-naturedly, and Gaal leaned out over the shoulder-high railing and bathed himself in all the panorama.
He could not see the ground. It was lost in the ever-increasing complexities of man-made structures. He could see no horizon other than that of metal against sky, stretching out to almost uniform greyness, and he knew it was so over all the land-surface of the planet. There was scarcely any motion to be seen a few pleasure-craft lazed against the sky but all the busy traffic of billions of men were going on, he knew, beneath the metal skin of the world.
