While we really don’t know exactly what a black hole is or where it leads, the best information available today indicates that even our universe might be inside a black hole that is part of something even larger (maybe even another universe). This type of thinking has led scientists to think about black holes as [...]
The answer to this question might involve becoming a space traveler. Scientists have developed the theory that objects that are pulled into a black hole might move through a tunnel (sometimes called a worm hole) and end their journey in another spot in the universe. The trip would happen very, very quickly.
It is not [...]
In an attempt to measure distance in space, scientists have combined two ideas – light and time. A different type of measurement was needed because of the huge distances needed to describe space. This is accomplished by using the distance light can travel in a particular amount of time.
For example, the star closest to [...]
Remember the old science question: If a tree falls in the forest and there is no one there to hear it, does it make a sound? The question here is similar. If a star literally exploded in space would we be able to hear it? Would we have to be very close to this major [...]
As with many questions about the universe and its creation, the answer depends on whom you ask. There is a huge segment of the world population that does not believe in the big-bang theory or any other scientific explanation for the beginning of our universe. There is another segment of the population, also quite large, [...]
For astronomers of the 20th century and beyond, a constellation is a specific area of what is commonly called space. In the past, the word “constellation” referred to easily visible stars that formed a certain pattern in the night sky. There is still some difference of opinion on the use of this term but some [...]
As is the case with the big-bang theory and other questions about our universe, the answer depends on whom you ask. Scientific studies and theory put the age of the universe at more than 13 billion years. This passage of time is measured from the big-bang moment that many scientists believe created the universe.
Studies have [...]
The best answer to our question might be, “Very, very fast!!” Light travels so fast in relation to everything we experience as humans that it is almost impossible to comprehend. In our terms, light travels at 186,282 miles per second in a vacuum. This speed isn’t changed by the source or where we stand when [...]
First of all, it is not physically possible to see a black hole. The term applies to a theoretical place in the universe that forms when a star’s mass experiences gravitational collapse. The mass of the star compresses into such a small space nothing can exit the hole (not even light). The theory has its [...]
Thought most earthquakes are big enough to cause major damage to buildings and injure or kill people, there are some earthquakes that are massive when compared to other geological events. Records indicated that the “biggest” earthquake recorded by the United States Geological Survey (USGS) took place in Chile in 1960. In fact, this South American [...]
