Now we can put this knowledge to use by going to where these bent rays are focused by the Sun's gravity. In this region, distant signals are tremendously amplified. A gravity focus can not be as sharp as a lens or mirror focus, so we will still need a large telescope. Launching this massive telescope up from Earth and then sending it the rest of the way to deep space would cost too much. We must make most of the telescope from nonterrestrial materials.
Asteroidal material is most economical.
We need to launch only some mass production equipment, because the vast majority of the mass of the telescope is mass-produced, simple metal collection dish and structural components. The fuel for transport is also abundant in asteroidal material. The last 50 years of man has seen amazing progress, and the next 35 years can see an evolutionary space program of revolutionary achievements for a better future for ourselves, our children, and the causes of the Free World.
