question 44

Multiple Choice

If we succeed in detecting signals from other civilizations in space,what method of communication will prove to be the fastest?

• A) Neutrinos,because a beam of these particles,suitably modulated,can be made to travel almost infinitely fast because they can penetrate almost anything very easily
• B) Nuclear-powered rockets,because we can then use unlimited power to accelerate these systems to almost infinite speeds
• C) Laser light,because this single-wavelength light can be directed into an extremely narrow and intense beam and can therefore be made to travel much faster than ordinary light
• D) It does not matter what is used because the speed of light can never be exceeded by anything in our universe,thereby setting the communication speed limit.
