But before we get to that, let’s take a look at how “material” – physical matter – first came about. If we are aiming to explain the origins of stable matter made of atoms or molecules, there was certainly none of that around at theBig Bang– nor for hundreds of thousands of y...
If the big bang theory is correct, then astronomers should be able to detect the expansion of the universe. Edwin Hubble, the namesake of theHubble Space Telescope, was one of the first scientists to observe and measure this expansion. In 1929, he was studying thespectra, orrainbows...
the standard model is simply the idea that every bit of the matter and energy in the universe was once compressed to an unimaginable density. In the big bang, the material exploded outward into the formation of matter that we see today. Shortly after this event everything in the universe wa...
Where did dark matter come from? How was dark matter discovered? Can dark matter be created? Can dark matter be used as an energy source? How much energy does dark matter have? What is dark matter made up of? How can energy exist before matter (the big bang theory) if energy comes ...
Astronomers (professional or amateur) can measure a star's brightness (the amount of light it puts out) by using a photometer or charge-coupled device on the end of a telescope. If they know the star's brightness and the distance to the star, they can calculate its luminosity — the am...
Is the end of the universe ten thousand light years away (as the Bible would predict) or thirteen billion light years away (as some astronomers would have us believe)? We examine the scientific data.
If the world and universe were supposedly 6,000 years old, then how come we can see light from over 13 billion light years away? What are the dimensions of power? Why is the universe flat? Explain. What does Hubble's law imply about the history of the Universe? Astronomers have detected...
This principle allows astronomers to see the universe as it looked after theBig Bang, which took place about 13.8 billion years ago. Objects that are 10 billion light-years away from us appear to astronomers as they looked 10 billion years ago — relatively soon after the beginning of the un...
This has led some to believe that our grasp of quantum physics is as basic as the understanding of ancient Egyptian astronomers centuries ago, who claimed that the sun was a god. A few scientists believe further investigation into quantum systems will reveal order and predictability within what ...
Astronomers Are Baffled by These New ‘JuMBOs’ Advertisement - Continue Reading Below Bubbles Could Explain Dark Matter and Why Antimatter is Scarce For example, one of the biggest outstanding problems in modern cosmology is why there is more matter than antimatter. Antimatter particles share all th...
