An objective universe…

[Marketa]

What is objective? We can see the same colors, shapes, sizes, positions etc. We can decide if some statements are true or not. But not always. What about our opinions? Our dreams? Are THEY objective? It’s clear that there are two worlds: ‘outside’ – the objective world, and ‘inside’ – our not objective world.
Physicists usually don’t acknowledge an ‘inside’ universe. Why? Is it so difficult to explain? It is too easy. We (people) are very complicated. We can see more than the objective space. In fact, this objective space is just part of us. Great one, I guess. But there is another part: we might be able to show how our brains and bodies work in the future – maybe we’ll see, hear etc. what someone else (another person) can see, hear,… on a display of a computer. But this picture isn’t a living person, it is what it is – a picture. And the difference between this picture and a living person is another part of us.
Imagine people like different universes: each person has its own space/he/she is a different space (own Sun, Earth, dreams, stars, etc.) And then do penetration: what we share is our objective world, other parts are not shared and we have no (direct) access to them (but we can use the collective part – like sounds, pictures to try to explain the most important things – so we talk, write…).
That’s the smart explanation of an objective world (and why the whole world is not objective).
And because physicists don’t count with ‘above’ an objective universe, they have problems with explanations e.g. of quantum physics.

this is strongly conected with Kant's philosophy.

Completely perfect objective reality does not exist. This is, because if you, fo rexample, whach something from a privilage view (ex: something happens in the universe, you can whach it from the outside) you are whaching it from a view, so it's relative, so it's subjective. If you have "god`s property" of being everywhere, you still are relative and subjective, because:
1)you are whaching it from a position: the one that whaches everything from everywhere and
2)you areyou, so it's your mind and brain that determines how ou interpret phenomena.

Not only humans are subjective, but everything. Objhectivity only exists theoretically.

I will continue the post tomorrow.

Marketa,

I agree with Einstein when he says that the external world has an independent existence regardless of our subjective perception of it. In other words, the objective reality is the one and only reality. This reality includes living things like ourselves.

For us to live, the physical conditions must be just right. Conditions such as temperature, amount of oxygen in the air, atmospheric pressure and the forces of gravity, electromagnetic, weak and strong. These are the conditions set by the Anthropic Principle. All the physical constants must be what they are in order for living things to exist. But the ideal earth environment, ideal for us, cannot be found duplicated anywhere else within the Solar System. This is a mystery to me. Scientists are still hoping to find traces of past or present life on Mars and maybe on a moon of Jupiter.

I think we would have already noticed if mars has life on presence. And if we haven't, and there IS life right now, theist should pray to their gods, because they would be one of these:
1) really advanced, and able to become "invisible" to our senses and machines, because they have done incredibly advanced studies and noticed that if we entered inc ontact wit them now, or before in past, it would have been a too-dificult subject with probably many negative things (which would mena they are inctredibly more advanced than ours in mind) or
2) that they are maybe not so advanced in mind, but yes in body: whcih ma be worst, because they would have the ability of being invisible to us, I hope that H. Wells was wrong, and Marcians aren't studying us in detail, arriving to conclusions that we don't deserve this world (Spielberg's "The war of the worlds" new film is an adaptation of the book (great one: both film and book).

One of the key conditions for sustaining any form of life is nonpoisonous water and atmosphere, which is equivalent to their oxygen contents.

Mars has an atmosphere but it has no surface water.
Venus has an atmosphere overrun by greenhouse effects and surface water is doubtful due to extreme temperature.
Both Saturn and Jupiter are gaseous planets of mostly methane gas which is hazardous to life.
