The marvelous telephone and television network that has

now enmeshed the whole world, making all men neighbours,

cannot be extended into space. It will never be possible to

converse with anyone on another planet. Even with today's radio

equipment, the messages will take minutes—sometimes hours—

on their journey, because radio and light waves travel at the same

limited speed of 186, 000 miles a second.

Twenty years from now you will be able to listen to a friend

on Mars, but the words you hear will have left his mouth at least

three minutes earlier, and your reply will take a corresponding

time to reach him. In such circumstances, an exchange of verbal

messages is possible—but not a conversation.

To a culture which has come to take instantaneous

communication for granted, as part of the very structure of

civilized life, this “time barrier” may have a profound

psychological impact. It will be a perpetual reminder of universal

laws and limitations against which not all our technology can

ever prevail. For it seems as certain as anything can be that no

signal—still less any material object—can ever travel faster than

light.

The velocity of light is the ultimate speed limit, being part of

the very structure of space and time. Within the narrow confines

of the solar system, it will not handicap us too severely. At the

worst, these will amount to twenty hours—the time it takes a

radio signal to span the orbit of Pluto, the outer-most planet.

It is when we move out beyond the confines of the solar

system that we come face to face with an altogether new order

of cosmic reality. Even today, many otherwise educated men—

like those savages who can count to three but lump together all

numbers beyond four—cannot grasp the profound distinction

between solar and stellar space. The first is the space enclosing

our neighbouring worlds, the planets; the second is that which

embraces those distant suns, the stars, and it is literally millions

of times greater. There is no such abrupt change of scale in the

terrestrial affairs.

Many conservative scientists, appalled by these cosmic gulfs,

have denied that they can ever be crossed. Some people never

learn; those who sixty years ago scoffed at the possibility of flight,

and ten years ago laughed at the idea of travel to the planets, are

now quite sure that the stars will always be beyond our reach.

And again they are wrong, for they have failed to grasp the great

lesson of our age—that if something is possible in theory, and no

fundamental scientific laws oppose its realization, then sooner or

later it will be achieved.

One day we shall discover a really efficient means of

propelling our space vehicles. Every technical device is always

developed to its limit and the ultimate speed for spaceships is

the velocity of light. They will never reach that goal, but they will

get very near it. And then the nearest star will be less than five

years voyaging from the earth.[514 words]
