Crazy Space Theories

Crazy Space Theories

  There is no doubt that our Universe is more stranger and full of magic place than we could ever imagine. In the vast space of the Cosmos there are phenomenons which are still being unexplainable even for the most penetrating science. In our trying to understand it and to give a answer to one of the most fundamental questions about existence the countless theories were born. In the next lines I will present few of the them- some  are well founded, others are literally crazy, but if some of them one day turn out to be true will change the whole understanding...
How Many Galaxies Are in The Universe?

How Many Galaxies Are in The Universe?

Staring at the night sky in front of us reveals infinite space full of small flashing lights. Some of them are planets of the Solar System but the rest are stars of our own Galaxy-  Milky Way. Even if we have to be precise all the stars we see with the naked eyes are  from our sleeve of the Galaxy. But we already know that this is not everything, we know that the Universe is filled with many Galaxies- some smaller and others much larger than the Milky Way. But how many Galaxies  are in the Universe? This question is...
How Many Universes Are There?

How Many Universes Are There?

This question is the center of some of the most passionate disputes. According to the theory, there are an infinite number of universes, each of them settled by its own laws of physics says TedEd For many scientists this theory is pure fabrication because there is no evidence or mathematical laws that even hint that such a thing exists. Believers counters that there is nothing that can prove the opposite. This mystery can be solved only if there is a way to go in this other universe and see it with our own eyes. Unfortunately, with the constant expansion of...
How Far Actually We Can Go into Space?

How Far Actually We Can Go into Space?

  When we speak for studying of the vast space, how far can humanity go into Space? – asks Science Alert? Is there a limit to our ability for going beyond Earth? As explained by this video channel Kurzgesagt – In a Nutshell, our Planet is located in one corner of the Milky Way – a ordinary galaxy full of stars, planets and a huge black hole in its center. The nearest neighboring galaxy is Andromeda and with it another 50 other galaxies, the Milky Way belongs to a local group with a diameter of about 10 million light years. Knowing...
What is Gravity?

What is Gravity?

We all know what is Gravity – it is what keeps us down to Earth. It is the thing that makes apple to fall next to the tree. But what is the definition of Gravity in physics?  It’s one of the fundamental interactions in the Universe. Fundamental interactions in physics are four completely different in nature interactions between elementary particles and bodies that they build. Many efforts in modern physics are focused at finding a common unified theory that would unite all interactions. So far, such a theory is not found. Here they are: Gravitational interaction Electromagnetic interaction Strong nuclear...
Speed Of Light

Speed Of Light

      Perhaps all you have heard at least once the expression “Speed of Light”. If you are from those who know that this is something very fast but  do not know how much actually, I will say that it’s about 300000 km/sec or  670,616,629 mph (miles per hour) and that is the speed of the photon – the only particle with no mass, and will add that there is nothing faster than it. In fact, because we see thanks to photons that pass through our eyes,  if their speed was much more slower we would see everything around behindhand. It sounds...
We Are All Made of Stardust

We Are All Made of Stardust

  The story of the Universe began 13.7 billion years ago and now there are more than 100 billion galaxies with a trillions of stars. If it’s hard to imagine how many stars is this let me use a example to make this easier. Imagine that you are on the beach and scooped up a handful of sand. Can you guess how much grit you are holding at this point? Yes, the number is definitely big! Now imagine the count of all the grains of sand on Earth- in every beach, every riverbed, each marine or ocean bottom. In the...
