When it comes to upper pecs, the study found that the incline bench is just slightly more effective than the flat or decline bench. The study also tested grips, and found that a narrower grip (just beyond shoulder width) combined with an incline bench press is the best for those upper pecs.
You are currently converting speed units from speed of light to miles per hour. 1 c = 670616629.3844 mph. speed of light. c. miles per hour. 670616629.3844 mph.
Light is actually slowing down. At the beginning of the universe, the speed of light AND the speed of GRAVITY were the same. Since then, light has been slowing down while gravity still moves at it's original speed. That speed, THE SPEED OF GRAVITY, is 20 MILLION times faster than the speed of light. So, if you wanted to get to Alpha Centauri in minutes, you need a GRAVITY DRIVE system. I thought you should know.
