To place a man in a multi-stage rocket and project him into the controlling gravitational field of the moon where the passengers can make scientific observations, perhaps land alive, and then return to earth - all that constitutes a wild dream worthy of Jules Verne.
The New York Times' was enigmatic: 'Some unimaginable gravitational force is pulling our entire galaxy in the opposite direction.' End of article. If you stop and think about that, we are recreating ourselves.
General relativity predicts that time ends inside black holes because the gravitational collapse squeezes matter to infinite density.
Recent results from astronomers who study the occasional gravitational lensing of unknown worlds by intervening stars suggest that orphan planets could be at least as numerous as the stars. In other words, there could be hundreds of billions of orphan worlds shuffling through our galaxy.
The human body experiences a powerful gravitational pull in the direction of hope. That is why the patient's hopes are the physician's secret weapon. They are the hidden ingredients in any prescription.
My bottom is so big it's got its own gravitational field.
Even if 'going retrograde' or 'moving into Aquarius' were real phenomena, something that planets actually do, what influence could they possibly have on human events? A planet is so far away that its gravitational pull on a new-born baby would be swamped by the gravitational pull of the doctor's paunch.
Gravitational and electromagnetic interactions are long-range interactions, meaning they act on objects no matter how far they are separated from each other.
I think about the cosmic snowball theory. A few million years from now the sun will burn out and lose its gravitational pull. The earth will turn into a giant snowball and be hurled through space. When that happens it won't matter if I get this guy out.
Music pulled me like a gravitational force. I entered college as a physics major but left as a Bachelor of Music, a degree with the same practical application as, say, one in the History of Chinese Poetry.
