Insane (But True) Things About Limits of Humanities
How far can Humanity go ?


What are the limits of Humanity ? This is a Space blog so we would only be talking about the limits of Humanity in Space. The technology we have today doesn't let us go anywhere farther than our Solar System. But in about,say, a Billion years Humanity may reach the Kardaschev scale - III type civilisation where moving within a galaxy or two may not sound so stupid as it does today.

Local group of galaxies


The Milky Way is a spiral galaxy, 100,000 light years across in distance. The Milky way is in a group of 50 more galaxies along with Andromeda known as the Local Group. So even if we reach the type - III civilisation, we would not be able to go any further than the local group. Now that is a brain twister Why the hell can we not go further ?

Why we cannot go further than the local group ?

With a type - III technology we would have the liberty to access all the Galaxies within the Local Group but beyond it there is a energy named Dark Energy, which won't allow us any further. 

To make you understand how Dark Energy stops us from travelling any further we would have to go about 13.8 billion years ago, when it all started. After the Big Bang, the size of the Universe expanded from a size of a marble to millions and millions of kilometers in seconds at unimaginable speeds but then Gravity stepped in to counteract the Expansion. The clash of Titans resulted in the victory of Gravity but in smaller scales because of which a galaxy or groups of galaxies were allowed to form. But Dark Energy played its part by moving other things in the Universe away from each other, nearby local groups are already millions and millions of light years away from us and at the time we reach the type III scale, everything outside the Local Group would be gone too far to be seen again. Dark Energy is pushing away everything in the Universe farther and faster (and by faster we mean tremendous and unachievable speeds).

Birth of The Universe


So that is why would never be able to reach other groups even if we reach the apex level of civilisation. Its amazing that one day we would have nothing to observe except the Local Group we live in. Nothing but Darkness, nothing from the past and no details about The Big Bang. Darkness and Darkness is all that we would see around ourselves. But we would still have the liberty to move in about billions of solar systems and planets inside our Local Group. We must consider ourselves lucky that we have the privilege to look back in time of how it all started and what wonders our Universe has !

Why your god never works out the way you plan ?

What do you think scientists or science preachers don't believe in god ??? Maybe you could be wrong this time.... All leading scientists and theorists like Dr.Michio kaku and Neil De Grasse Tyson , and all are a firm believer of god. The difference is their concept ual belief on god is quite different from that of others.            From early times, man has been a firm believer of god and its creation. The different cultures in different countries and continents have made a variety methods of god's existence based upon their divisions. But scientists , theorists and thinkers have a very common belief on god. 1. God is no material - According to leaders god is no material, and we can never imagine how he / she looks, what are his habits, what its past is and so. 2. God could be a mathematician - Yes, according to scientists god could be renouned mathematician, the Universe is the biggest example of it, everything in the Universe is calculative. 3. God is g

5 theories and predictions on what could be there outside the Observable Universe. The Observable Universe; The Universe we know   Have you ever imagined  what could possibly be there outside the observable Universe ? Since Humans have shown interest in space there has always been a curiosity if the observable Universe is all it is or something more is out there. To know what could be possibly out there beyond our vision we first must understand what is the observable Universe ? Now, the Observable Universe according to humans is the part of the Universe availaible to be seen to us. Let's make it a bit simple each and every star, planets and galaxies, everything visible today to us in space is the observable Universe. The Observable Universe is roughly 14 billion light years old, that is, the oldest light we receive from any star or source from space is about 14 billion light years away from us and this is the time we think the Universe was created !  So no

Types of Civilisations - Kardashev Scale

Types Of Civilisations - Kardashev Scale  Types of Civilisations Kardashev Scale Life on Earth is so weak and fragile, in comparison to activities happening in Space. We have our own troubles in the form of Volcanoes, Earthquakes, Tsunamis and the list just goes on and on. An asteroid attack from Space can wipe out the whole of Humanity, like the one which wiped out the Dinosaurs, 66 million years ago. So looking at the scenarios Earth maybe looking for ways to kill us !  Maybe we as a civilisation are not yet strong enough to save ourselves from planetary as well as cosmic disturbances. How could we move to a better civilisation ? In 1964, A Russain Astrophysicst Nikolai Kardashev proposed the system for all possible civilisations on the cosmic scale. The scale was named as the Kardashev Scale after his name . The kardashev scale distinguished Civilisations into three types Type - I, Type - II, and Type - III based upon the energy each can produce.  Type - I
