prevents light from escaping. He called these objects “dark stars”‚ which we now know as black holes. With later knowledge of the theory of relativity‚ scientists were able to find out that when so much matter is concentrated in a small region‚ gravitational forces are so strong and space so extremely warped that light is no longer just being bent‚ but trapped inside the object (see image on the left). Although the concept of black holes is relatively old‚ the findings and research on them are quite

From millennium-skipping Victorians to phone booth-hopping teenagers‚ the termtime travel often summons our most fantastic visions of what it means to move through the fourth dimension. But of course you don’t need a time machine or a fancy wormhole to jaunt through the years. As you’ve probably noticed‚ we’re all constantly engaged in the act of time travel. At its most basic level‚ time is the rate of change in the universe -- and like it or not‚ we are constantly undergoing change. We age

5 of the biggest unsolved mysteries in physics The mysteries of the universe are as vast and wide as existence itself. Throughout history‚ mankind has searched and struggled to find the answers tucked away inside the universe and everything we see around us. As Deep Thought said in the Hitchhiker’s Guide to the Galaxy‚ "I think the problem‚ to be quite honest with you‚ is that you’ve never actually known what the question is." True‚ we have yet to come up with the answers to life‚ the universe

The Life Cycles of Stars In the universe‚ there are hundreds of billions of stars. They are formed when gas and dust from space "clump" together. As the mass grows larger‚ gravity takes over and a core begins to form. The core becomes extremely dense and this compaction causes temperatures within it to rise to the point where nuclear fusion (the burning of hydrogen in a chain reaction) can begin. The heat generated by fusion can reach 24 million degrees F (Fahrenheit). "That amount of heat keeps

Theoretical Physics‚ a modern topic of science with an extremely deterring sound and famous for being beyond complex‚ is a subject which cannot be explained with ease. Stephen Hawking‚ the most famous living scientist today‚ wrote A Brief History of Time in 1988‚ updated in 1996‚ in order to take upon this daunting task of explaining basic theoretical physics to a population who had previously barely studied any science. Within A Brief History of Time‚ Hawking touches upon seven topics in-depth while

------------------------------------------------- State of matter From Wikipedia‚ the free encyclopedia States of matter in physics are the distinct forms that different phases of matter take on. Four states of matter are observable in everyday life: solid‚ liquid‚ gas‚ and plasma. Further states are possible but do not naturally occur in our environment: Bose–Einstein condensates‚ neutron stars. Other states‚ such as quark-gluon plasmas‚ are believed to be possible.
