Introduction:
Dark matter is the invisible visible that has made its presence known so far only through its gravitational effects. Thus the invisible form of matter that cannot be seen or touch is termed as dark matter, and its presence is detected by its gravitational effects.
The dark matter affects the orbit of the stars as greater the force of gravity, so greater the orbital speed. The stars near to the dark matter have a higher influence of gravitational force and the stars away from the dark matter have a lower influence of gravitational force. So the stars near to the dark matter have the higher orbital speed and the star far away from the dark matter has the slower speed. Thus, the dark matter is affecting the orbits of stars.

Their message encourages us to send a radio answer, which we decide to do. Suppose our governing bodies take 2 years to decide whether and how to answer. When our answer arrives there, their governing bodies also take two of our years to frame an answer to us. How long after we get their first message can we hope to get their reply to ours? (A question for further thinking: Once communication gets going, should we continue to wait for a reply before we send the next message?)arrow_forward
