Is Thorium An Untapped Energy Source?

Is Thorium An Untapped Energy Source?

What do you think? The search for efficient alternative energy is discussed daily.  Some think solar is the answer.  Others think wind energy or even forms of hydro power are areas to focus on.  These may be great sources but there is one that is rarely discussed.  Thorium is an element and #90 on the

Can The Speed Of Light Actually Be Broken?

It is 186,282 miles per second… This guy has an interesting theory on how it might be possible.  That is insanely fast and difficult to get one’s mind around.  The ever interesting “vsauce” poses a question about the speed of dark.  Is it faster than the speed of light or is this an illusion?  He has

New Theory That Black Holes Don’t Exist?

Is this Possible? Most astronomers and space fans alike have a fascination with black holes. They seem to defy the laws of the physics that we think we understand. However, there is a new theory that they potentially don’t exist. Wait…what? yes you read that correctly. Astrophysicists Laura Mersini-Houghton and Herald P. Pfeiffer have come

Can The Speed Of Light Be Broken?

The ever clever Veritasium examines one of the most debated topics in science year after year.  Can anything actually travel faster than the speed of light?  If so, what type of propulsion system or physics would be involved in such an endeavor.  He goes over a few scenarios where this could theoretically take place. Will

This Unusual Asteroid Has Rings

How did these form?  Apparently the asteroid Chariklo has rings like you might see on a planet: From ESO, observations made at telescopes in South America have made the surprise discovery that the remote asteroid Chariklo is surrounded by two dense and narrow rings. This is the smallest object to have rings and only the

Do You Know About The Banach-Tarski Paradox?

The every interesting VSauce examines the Banach-Tarski paradox in theoreticgeometry.  It is hard to get one’s mind around this one but he explains it very thoroughly and it involves thinking about 3 dimensional plains in a new way.  Once commenter even says: I lost you after like 6 minutes Some one else has a similar

Is Anything Faster Than The Speed Of Light?

What do you think? Some scientists say that “tachyons” might be able to do it.. The ever entertaining Veritasium examines the question, can anything travel faster than the speed of light.  People actually are in both camps, and it is almost impossible to discuss this debate without referencing the work of Einstein from earlier in

How Big Is The Universe…Is It Infinite?

Many of us science fans have pondered the question of just how big is the universe.  This video examines these questions: Does the universe go on forever? Where do we fit within it? And how would the great thinkers have wrapped their brains around the far-out ideas on today’s cutting edge? For those who find

Will People Colonize Mars Like This?

Do you remember the biodome projects?  This video examines the preperation, both physically and in terms of planning if we were to colonize Mars.  Is this completely far off or would it actually be a possibility.  From the propulsion, to nutrition needs, gravitational changes and more, there is a lot to take into consideration. Let’s

Could Glass Actually Be A Liquid?

They make an interesting case in this video that glass could actually be a liquid.  Of course this goes against what we were taught! At school, we’re taught that there are three basic states of matter: solid, liquid, and gas. But out in the real world, it’s often not as easy as you might think

Extremely Rare Lightning Sprites Seen [Video]

Have you ever heard of these? This video examines a controversial explanation for an atmospheric phenomenon called sprites.  Here is a quick intro from wikipedia: Sprites are large-scale electrical discharges that occur high above thunderstorm clouds, or cumulonimbus, giving rise to a quite varied range of visual shapes flickering in the night sky. They are triggered

How Large Can A Telescope Actually Be?

Do you know? They keep making larger telescope arrays so the question is how large can they actually be? From ESOCast: on clear nights we can look up at the stars and marvel at the vastness of the universe. Our eyes quickly adapt to the dark. As our pupils widen, more light streams onto our

How Would Our Solar System Look To An Alien?

Have you ever wondered what our solar system would look like to an alien?  We often spend time and money searching for evidence of extraterrestrials, especially with the focus recently on exoplanets.  The most famous of course was discovered this year names Kepler 452-b.  If you haven’t heard, it is considered to be the most

Is The Universe Infinite? [Video]

Is the universe infinite and can you get your mind around this?  There have been many perspectives but no one knows for sure.  This video examines this incredible question: How far do the stars stretch out into space? And what’s beyond them? In modern times, we built giant telescopes that have allowed us to cast
