Weightlessness versus Gravity

  1. Apr 27, 2016 #1
    Scientific greetings to everybody within the forum,

    Is there any possibilities to create intelligent light in order to send it to the universe and then analyze its reflection for more knowledge? If this happens, there will be no need to make expensive and heavy spacecrafts and launch them? To do so, the problem of human being's slow race in proportion to universe will advance a lot?

    I appreciate the probable replies in advance.

    Do you mean we should probe the universe by observing the light reflected off matter (e.g. planets and stars)? We are already doing that. The observable universe is billions of light years in diameter already!
