Testing Einstein’s E=mc2 in Outer Space

UA physicist Andrei Lebed has stirred the physics community with an intriguing idea yet to be tested experimentally: The world’s most iconic equation, Albert Einstein’s E=mc2, may be correct or not depending on where you are in space.

With the first explosions of atomic bombs, the world became witness to one of the most important and consequential principles in physics: Energy and mass, fundamentally speaking, are the same thing and can, in fact, be converted into each other.

This was first demonstrated by Albert Einstein’s Theory of Special Relativity and famously expressed in his iconic equation, E=mc2, where E stands for energy, m for mass and c for the speed of light (squared). (more…)

Biodiversity: The most common issues

Environment

Biodiversity can be considered as an imperative factor that plays a crucial role in poverty reduction owing to its basic goods and the ecosystem services it provides. Over three billion people rely on coastal and marine biodiversity and about 1.7 billion people depend upon non-timber forest products and forests for biodiversity.

Common issues relating to biodiversity can be classified as:

Biodiversity as a source of income and food

World’s poor population, especially living in rural areas are dependent on biological resources for meeting most of their needs. At least, 90 percent of their needs relating to fuel, shelter, medicines and food come from biological resources. (more…)
