NASA's Wilkinson Microwave Anisotropy Probe (WMAP) provided a true watershed moment in humanity's quest to understand the cosmos when it calculated the age of the universe and plotted the curvature of space. It also mapped the cosmic microwave background radiation and, in a shocking turn of ev...
The event horizon is a boundary that marks the outer edge of black holes. It is the point at which nothing, not even light, can escape.
California made many other errors, but its decision to get single-deck trains is correct in its use case: the high-speed trainset market is almost entirely single-deck, and the issue of platform length is not relevant to captive high-speed rail since the number of stations that need high-...
Before moving on from Cunningham Falls, it is important to note that Camp David is located in the vicinity. As I learned more about earth grids, I found out that Camp David is situated on a nodal point. It is the norm for centers of power to be on the earth’s power points. There...
The German-American physicistAlbert Einsteinbrought about the next revolution in our understanding of gravity. Histheory of general relativityshowed that gravity arises from the curvature ofspace-time, meaning that even rays of light, which must follow this curvature, are bent by extremely massive obj...
[For other articles of mine on this subject, focusing on particular topics, see here, here, here or here] The term ``virtual particle'' is an endlessly confusing and confused subject for the layperson, and even for the non-expert scientist. I have read m
Note that the centripetal acceleration is related to the curvature, so you can't use the equation for a circular orbit. What do you know about angular momentum? Apr 20, 2016 #3 Tissue 23 0 The angular momentum is conserved as the gravitational pull by the Earth is...

This simple tweaking of the formalism had deep consequences. For one, the left-hand side of the field equations is not zero anymore in flat space-time, implying a curvature of empty space. When the experimental verification of the expansion of the universe was established, Einstein repudiated th...
