The nearest star to our solar system is 4.29 light years away. How much is thisdistance in terms of parsecs? How much parallax would this star (named Alpha Centauri) show when viewed from two locations of the Earth six months apart in its orbit around the Sun ?
How can forces be unified?
A star is observed to have a parallax of 0.05". If we were to send a radio signal towards this star how much time would it take for the signal to reach the star?
