as Jupiter makes each orbit. On Earth, we have to contend with our own gravity well when we launch rockets and spacecraft; if a rocket isn't powerful enough to escape its gravity well, it will ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum ...

And because gravity is also tied to our concepts of motion ... invisible substance that makes up the bulk of all the mass of every galaxy. While that hypothesis has been able to explain a vast ...

It is gravity that keeps us firmly on the ground and what makes objects fall. Without gravity, everything on Earth would float away. Gravity acts on all objects. The larger the object, the greater ...

We have this beautiful theory about how gravity works in astrophysical distances, thanks to Einstein’s theory of relativity. But we also know it doesn’t work when we apply that same theory to quantum ...

(Submitted by Claudia de Rham) What makes gravity such a difficult concept to understand scientifically? So one of the aspects of gravity as discovered by Einstein himself, was that we can ...

The most common approach to this reconciliation has been to try to make gravity quantum. After all, we got a theory of quantum electromagnetism by quantizing the electromagnetic field.

Spiegel thinks that when stress taxes the amygdala, a person begins overreacting to potential threats, including gravity. The digestive issues that make up IBS are a manifestation of that ...
