What do you think is the most critical policy issue facing America today? Why? How are our policy makers doing and why do you think so?

The most critical policy issue facing America today is the rivalry between Democrats and Republicans, Antifa and Trump supporters, left and right, progressives and conservatives; in short, the inherent social conflict in American society today, which is creating a series of increasingly serious social confrontations among the nation's citizens. Clear examples of this situation are the assassination of George Floyd, the assault on the Capitol by Trump's followers, the constant excesses of Antifa in his mobilizations, and the growing tension between both political groups.

Unfortunately, our government is not taking the necessary measures to unite the nation, but rather each political party operates according to its own interests, increasing the severity of the problem more and more.

light-year  

the distance that light travels in a vacuum in one year, equal to about 9.46 trillion km (5.88 trillion mi). light-years are used in measuring interstellar and intergalactic distances.  

parsec  

a unit of distance used in astronomy, equal to about 3.25 light years (3.08 × 1016 meters).  

parallax  

the apparent angular displacement of a celestial body due to its being observed from the surface instead of from the center of the earth (diurnal parallax or geocentric parallax) or due to its being observed from the earth instead of from the sun (annual parallax or heliocentric parallax)  

absolute magnitude  

the magnitude (brightness) of a celestial object as it would be seen at a standard distance of 10 parsecs.  

apparent magnitude  

the magnitude of a celestial object as it is actually measured from the earth.  

redshift  

an increase in the wavelength of radiation emitted by a celestial body as a consequence of the doppler effect.  

the great thing about your imagination is that it doesn't have to make sense! if i were you i would be stuck in space, no communication with earth travelling around and around, you can only guess how long its been since your communication broke down. you land on an undiscovered planet, you do a scientific investigation examining the elements and conditions. you come across alien lifeforms.  

best of luck!
