Space and Time, or Spacetime

Henceforth space by itself, and time by itself, are doomed to fade away into mere shadows, and only a kind of union of the two will preserve an independent reality. (Herman Minkowski, 1908)

Albert Einstein's space-time will astonish and amaze you
Albert Einstein’s space-time will astonish and amaze you

The universe is made of different types of matter and energy traveling through space as time passes unnoticed. Until the time of Einstein, scientists thought and discussed time and space as though they’re absolute and distinct, which is the way they appear to our senses in everyday life. But what if reality is different then it appears?

At the beginning of the twentieth century, Albert Einstein introduced the idea of space and time intertwined in an amazing manner described mathematically by Einstein’s theories of relativity. A scientific theory originally published as two separate parts; the general and special theories of relativity, Einstein’s theories of relativity are currently the most accurate method scientists have to predict physical theory in our universe.

The goal of this series of articles is to show the ability of Einstein’s space-time to help us understand the true nature of physical reality in the universe. This will be accomplished by first providing knowledge and understanding of the flat space-time of the special theory of relativity and consequences of the theory such as length contraction, the twin paradox and time dilation. Next, we’ll offer an introduction to the nature and consequences of the curved space-time of the general theory of relativity, including the idea of an ever-expanding universe, and the nature and meaning of black holes.

The first article in the series is titled “Einstein’s Revelations on Space-time”. This article will be posted during the months ahead and talk about the life and work of Albert Einstein and its stunning revelations for space-time. Einstein’s theories of relativity and their dramatic consequences concerning the true nature of space-time are considered by many to be the greatest scientific discovery of the century. They have replaced ideas concerning the true nature of space and time believed since the age of Newton and Galileo, and are often difficult to grasp at first. In order to better comprehend the theories of relativity readers need to abandon preconceived notions concerning the nature of time and distance measurements, simultaneity, and causality in the universe.

Time and distance measurements in Einstein’s space-time will surprise and startle you and simultaneous events will fool you if you aren’t mentally sharp. The limiting nature of the speed of light also results in interesting consequences for cause and effect in the universe.

Welcome to Einstein’s universe!

Meteorite Shower Could Lighten Southern Canadian Skies

Space news (the solar system: comets and asteroids; Comet 209P/LINEAR)

Debris ejected from Comet 209P/LINEAR during the 18th – 20th centuries could lighten the skies in southern Canada tonight. Expectations are for a possible Camelopardalis meteorite shower between 2 – 4 a.m EST tonight. Astronomers aren’t really sure if the show will be spectacular or a small production. In fact, they don’t have any data indicating how active the comet was during the past two centuries when the comet’s debris tails are believed to have been created.

The show could be one to forget or unforgettable, it all depends on a lot of factors. As the Earth passes through the debris field of Comet 209/P LINEAR tonight, small pieces of dust and particles could be released into the atmosphere that will create bright streaks of light we call meteorites. Estimates run as high as 200 meteorites per hour are being thrown around, which is 100 meteorites higher than the Perseids and Leonids in November. This could probably best be termed a meteorite storm, rather than a shower, and the true number could be even higher.

The best time to view the Camelopardalis meteorite shower is 12 midnight May 24, 2014, but I suggest you get there early. The shower will occur through a very narrow window of opportunity for viewers in southern Canada if we get a show to see. You won’t need to use binoculars or a telescope, just bring a blanket to lay on or chair to sit in, and something to warm the stomach.

 

Pick the darkest spot you can conveniently reach and you should be able to see even faint meteorites, which are probably unassociated with the Camelopardalis meteorite shower. White light will destroy your natural night vision, which will take 15 to 30 minutes to return. This includes light sources like cell phones and flashlights unless the light is red, so keep this in mind.

 

Look toward the Big Dipper and find the last star from the spoon. Just follow this star toward the first bright star you see. This star is Polaris and the constellation Camelopardalis, the area of the sky where the Camelopardalis meteorite shower originates, is near this star.

 

The most important thing to remember is to look upward during the window of opportunity. Many viewers forget to follow this simple tip and miss part, or all, of the meteorite show.

Earth Mission Discovers Something Unusual

Space news (August 05, 3897)

Archaeoastronomers of the Earth Mission today discovered something unusual under the dry sand of Chile’s Atacama desert. Buried ten to fifteen feet under the hot, dry sand of the Chajnantor plateau of the Chilean Andes at an altitude of 5,000 meters they discovered a human relic from an early age. What appears to be a human made instrument scientists date to about 2014 AD.

Space scientists unearthed a 12-meter concave metal dish, broken off at the base. The origins and design of the artifact are a mystery to space scientists and historians at this point. Records from this period of human history are sketchy at best, so historians are at odds as to the original use of such a weird looking artifact.

Chile’s Atacama desert is a very isolated and unforgiving environment today and we expect it wasn’t much more inviting in the twenty-first century AD. Documents from the time indicate this region was home to a large facility of some type, possible scientific in nature, but it isn’t clear just what they were studying.

Archaeoastronomers indicate ancient records point to humans of this period being intensely interested in the solar system and the study of the stars in the night sky. Even today space scientists indicate the high plateaus of Chile’s Atacama desert are the perfect spot to observe the sky. This leads archaeoastronomers to believe the site was possible the home of an ancient observatory of some kind.

“The true origins, design, and uses of this artifact are at this point a puzzle, but we believe the 12-meter dish was part of a scientific instrument of some type. Humans of the 21st century spent a lot of time and resources studying the solar system and stars. We think this artifact was part of a much larger instrument and facility,” said lead archaeoastronomer of the Earth Mission, William Hurte.

Archaeoastronomers will now try to piece together the puzzle of this strange looking artifact, using the facts they have to go on, and continued the study of the site and surrounding region. The site is difficult to reach and the environment unforgiving and harsher than any we face here on Sintera. Space scientists face dangers from both the natural environment and strange lifeforms the Institute for Scientific Study is planning on sending a team to study at some point.

The questions at this point keep piling up for archaeoastronomers of the Earth Mission, but they have decades to piece together the puzzle.

What do you think?

Tell us what you think? Is this artifact an ancient weapon of some kind? A scientific instrument? Maybe an astronomical device?
