The muscles and correct posture maintain the natural spinal curves. Good posture involves training your body to stand, walk, sit, and lie so that the least amount of strain is placed on the spine during movement or weight-bearing activities (see Posture).
There are roughly 500 billion galaxies in the universe, meaning there is somewhere in the region of 50,000,000,000,000,000,000,000 (5Ã1022) habitable planets. Iâll leave you to do the math on whether one of those 50 sextillion planets has the right conditions for nurturing alien life or not.
And so, if you multiply the number of stars in our galaxy by the number of galaxies in the Universe, you get approximately 10 24 stars. Thatâs a 1 followed by twenty-four zeros. Thatâs a septillion stars. But there could be more than that.ccording to astronomers, there are probably more than 170 billion galaxies in the observable Universe, stretching out into a region of space 13.8 billion light-years away from us in all directions.
