At one time, some of Einstein’s theories of space-time and general relativity have exotic subjects within the solutions of the equations, such as wormholes. Einstein theory of space-time and general relativity has been tested many times and each test has raven the theory correct. However, we have not found any wormholes in space. But, is it just going to take new technology or time? In the early 1900’s black holes were theories and many scientists did not believe they existed, but today we have found many blackholes across the universe. The advent of general relativity transformed our understanding of gravity and introduced us to the idea that the underlying fabric of the Universe is a tapestry we call “spacetime.” That fabric is a dynamic entity, constantly evolving and changing. It can be bent, twisted, warped, and perhaps ripped. In the hundred years that we have been aware of spacetime, our understanding of it has been informed by astronomical observations, detailed mathematical calculations, vast computer simulations, and wild speculation. Some ideas and predictions, though exotic, have been found to be wholly true; others we are skeptical of, but cannot disprove; of others we still have no idea what to think.

December ’24 – Rick’s Picks
Transient Events That Can Give Us a Good Enough Reason to Get Outside and Do a Little ObservingAll month: the solar system continues to favor evening observers this month, leaving only Mars and Mercury for the sunrise crowd. Mercury is hidden in the Sun’s glare as...
Astronomy Fundamentals: Sparkling Winter Star Clusters
December brings a mix of emotions for amateur astronomers. The nights are longer, so there is more time available for viewing. In addition to longer nights, winter also holds some bright stars and constellations. But it comes at a price. The weather at night will be...
Celebrate the Centennial of Planetariums with a Visit to the New Shanghai Astronomy Museum
The history of planetariums can be traced back to ancient civilizations. In Greece, Archimedes created mechanical devices to illustrate celestial movement. In 1229, Emperor Frederick II used a tent with holes to represent stars, and rotated the tent to mimic the...
Focal Plane November ’24 – Searching for Gravitational Waves from Supermassive Black Hole Mergers
The October 3, 2024 NASA Universe of Learning featured discussion on gravity. One of the topics covered was searching for gravitational waves from supermassive black hole mergers. Chiara Mingarelli, PhD - assistant professor of Physics at Yale University,...
