Archaeologists digging at a Jerusalem site have found the oldest artifact that bears the inscription of Bethlehem — a 2,700 years old seal with the name of Jesus’ traditional birthplace. The tiny clay seal’s existence and age show Bethlehem was a bustling place of trade linked to the nearby city of Jerusalem, not merely a fabled biblical town.
Astronomers have found a galaxy that represents a new type, and falls within the range of active galaxies known as Seyfert galaxies. It glows green because of X-rays spewing from a gigantic black hole at its center that weighs several million to billion times more than the sun. Dubbed a “green bean” galaxy, it appears…
Lack of rain has left many rivers at low levels unseen for decades, and while this creates problems for river commerce, it also offers an occasional treasure trove of history. For example, a rock containing what is believed to be an ancient map has emerged in the Mississippi River in southeast Missouri, with etchings that may be 1,200 years old.
A first-of-its-kind “crowdsourced and crowdfunded” archaeological dig at Cambridgeshire’s Flag Fen has finished. It is the site of a Bronze-Age “causeway” of millions of preserved timbers that are rotting away as groundwater recedes from the site. The not-for-profit Digventures team raised £27,000 from members of the public who then joined in an expert-led dig to…
Contemporary physics posits an all-pervasive energetic field called “quantum vacuum energy,” or zero-point energy, a random, ambient fluctuating energy that exists even in so-called empty space.
†The origin of time asymmetry in the physical universe has exercised the attention of many of the world’s greatest physicists since the time of Maxwell and Boltzmann. The problem is easily stated. Almost all physical processes display a unidirectionality in time, yet the underlying laws of physics (with a minor exception in particle physics) are…
