In a relatively short period of time, heavy portions of the ball to be tested will rotate by gravity to its bottom-most position and, hence, the desired axis is vertical and thereby determined and can be marked by any convenient marking method....

The Sun and Earth provide a good demonstration of the difficulty. Earth is in a stable orbit around the Sun and despite the star’s huge size and far greater gravity compared to our planet, it’s thankfully unable to pull us in towards it. What actually falls into a black hole The rea...
The earth is not in the centre of the Sun's orbit nor at the centre of the universe, but in the centre of its companion elements, and united with them. And any one standing on the moon, when it and the sun are both beneath us, would see this our earth and the element of water...
These observations in combination with the infrared interferometry experiment GRAVITY at the very large telescope interferometer and other experiments across the electromagnetic spectrum might yield proof for the presence of a black hole at the center of the Milky Way. The large body of evidence ...
The Sun serves as a natural reference for the modelling of the various physical processes at work in stellar interiors. Helioseismology results, which inform us on the characterization of the interior of the Sun (such as, for example, the helium abundanc
Ball lightning A relatively rarely seen form of lightning, generally consisting of an orange or reddish ball of the order of a few cm to 30cm in diameter and of moderate luminosity, which may move up to 1 m/s horizontally with a lifetime of a second or two. Barber pole A thunderstorm...
In the latest chapter of the Athlete No One Saw Coming campaign, Jordan is seen working on her craft from a young age, building in both confidence and commitment as she carves out her path to greatness.“There is a select class of athletes whose talents have been rooted in greatness. ...
I have withdrawn publication of GEORGE tJh.e paper for the ROMANES. Oxford, July 1. which are the pendulous elliptic motions determined as above, &c." It is indeed obvious that a uniform motion in a straight line cannot be regarded in this manner, not even approximately for any length ...
A ball is dropped from the top of a 100m high tower on a planet. In the last $ \\dfrac{1}{2} $ s before hitting the ground, it covers a distance of 19m. Acceleration due to gravity (in $ {\\text{m\/}}{{\\text{s}}^2} $ ) near the surface o...
