We are a part of the Earth.
Humans can flourish on Earth, because we are a part of the Earth's biological system, a system that fits on the Earth, and probably nowhere else in this universe. Our lives are very delicate. If the conditions aren't just about exactly right; we'll get erased. Our body temperature for example, has to be about 37.5ºC. A couple of degrees warmer or colder is a major problem, and beyond that, we die. While the spectrum of temperature runs from minus −273.15 °C (0 K) up to millions or billions or such.
Our circumstances.
- We live on the surface of a planet, on the boundary of solid and gas.
- The force of what we call gravity, on that surface, is about 9.81 m/s^2.
- There is a thin layer of gas around our planet, a mixture gases in a spesific ratio.
- Our planet revolves around a star. Distance: 8 min and 19 s (light speed).
- 1 rotation of the Earth: 24 hours.
- 1 rotation of the Earth around its star takes about 365.24 rotations of the Earth.
This list can be made much longer: the kinds and ratio of atoms and molecules near the surface, 1 moon, the type of star, inner Earth temperature, machnetic field, average temperature and pressure of the atmosphere, ...
Very specific and unique circumstances.
Other circumstances are "hostile"
Some places at or near the surface of our planet are all ready uncomfortable or even very dangerous for us to be: too hot, too cold, too dry, too wett, to much pressure, too little pressure. Going away from the surface of our planet, brings us in a dangerous surrounding right away:
* Vacuum space = deadly
* Near a star = deadly
* Nebulas and whatever else is out there = deadly (probably)
* Travel times = deadly (other planets are very*very*very^extremely far away)
* Being on the surface of an other planet = 99.9999999% deadly (ah, some are ok!)
How many planets are there in this universe?
We don't know yet, but the amount is staggering. So, there is a chance of an other planet where we can live!
With protection only.
The only way we can go anywhere else, be anywhere else, is inside a thick protective shell.
Space ships, suits, artificial controlled atmosphere. That is: not healthy, not pleasant.
We belong on the Earth, because we are part of it.
We can to go into space, but where would you like to be; in a protective shell, or walking around free, without protection?
Is there alien life in this universe?
Of course there is!
Have you not yet discovered how big this universe is?
Life is probably present all over the place.
The one part of that 'alien' life is less evolved, and the other part is more evolved. The most evolved not years ahead of us, but more like millions of years further.
No; no proof yet.
If aliens are similar us.
Aliens that are similar to us, have similar problems: they are at home on their planet, where they are in balance with their planet's biological or whatever system, free to live without an protective shell. Maybe they have discovered how to travel way faster than light, but is there any other planet around as pleasant as their home planet?
If aliens are totally not like us.
What if there are aliens alive, very different from us. What could their possibilities and restrictions be? What for example if they are:
* not
sensitive for pressure and acceleration.
* not rundown by age.
* not depending on a specific atmosphere.
* not
sensitive for: heat, cold, and radiation.
Beings like these can live all over the universe, and travel without inertia.
Beyond biology.
What we humans can and cannot do, is largely dictated by the build of our bodies, which is a collection of atoms (or is it more than that?).
Once we are done optimising our DNA code, our social structures, and our balance with the rest of Earth's nature, we may be ready for the next faze; start living in other mediums, instead of living in a body made of atoms, choose an alternative medium, like for instance:
* Magnetic
* Neutrinos
* Photons
Just like the aliens mention above may have done, millions of years ago.
Alien size, speed, visibilty.
An alien can be as big as we are, but he or she or it is more likely to be bigger or smaller. How big or small? They could be so small that we should search for them with a microscope instead of a telescope! Or they could be so big that we don't see it, because we are inside of one! Clusters of galaxies do look a little like a nervous system...
An alien can move as fast as we, but more likely faster or slower. How fast or slow? They could move so fast that we can't see or measure them, or soo slooow that we don't notice it.
We are alive in a structure of atoms, and have our senses. Aliens could have there structure in an other medium, invisible to our senses and going straight through our atom body medium.
Human space travel
In order to travel to other galaxies within a reasonable time -say one year, we need the ability to travel much faster than light. The speed of light is amazing: 299,792,458 metres per second! That's more than 7 times around the Earth in 1 second. But the distances of the nearest star (other than our sun) is all ready measured in lightyears. Anything interesting in our galaxy is at least hundreds of lightyears away. And there are billions of other galaxies in our universe, the nearest one at 2.5 million light-years (the Andromeda Galaxy).
Rockets that accelerate fuel in order to accelerate their mass in the opposite direction, have no bright future. The fastest rocket of today (the NASA Pluto New Horizons spacecraft on an Atlas V rocket - 2006) goes to about 16093 metres per second relative to its start location. A waste of energy & mass, and not healthy to get so much G force on your body. How fast is that relative to the speed of light? It's 1/18629 the speed of light. To travel a distance of 1 lightyear at that speed would take 18629 years!
Even if we could transfer our bodies and stuff into information, and sent it coded in light, to a destination where we can become real bodies again, that would still be 'only lightspeed', thus too slow.
Serious space travel requires faster than light propulsion. Hopefully it is possible to alter the space around a craft in such way than the craft inside the center is experiencing normal space, while that space is moving at 'warp speed' relative to the space around it. "Nothing can travel faster than the speed light" ...good thing 'space' is our definition of 'nothing'.
But if we can't find a trick to travel faster than light, then that too slow lightspeed is our goal. Then if we can't find a trick to cancel the inertia of our atoms (the resistance against acceleration), there are two options: Transform our bodies into neutrinos (or such) during space travel, so that we can travel really fast and through most matter. If we can't even do that, we should just stay at home, and gain knowledge. Most of the universe is a hazardous place anyways. Often we want to go somewhere, to experience something new, which is about the same as gathering information, and then go home again.
FIRST CONTACT
If there is life all over the universe, there have probably been aliens on the Earth, a couple of times, in the last millions of years. Maybe an alien visitor started life on Earth.
Who knows. I don't. So here we are, passively waiting for first contact, again.
Imagine getting in contact with a far more developed species that has been in contact with countless of other even more developed species. That would be.. embarrassing, and hyper interesting!
That will totally change our world.
Dangers of contact with aliens
Before shaking hands, or tentacles, first beware of the dangers:
- The exchange of biological
stuff like: bacteria and viruses.
- They may only be interested in us -as food.
- They may have no interest in us at all. (like how we ignore most of nature).
- They may only be interested our planet's resources.
- They may treat us like how we have treated others (American Indians, take 'slaves' from Africa, Australian aborigines, Hitler's concentration camps, and so on ...).
- Both of us may react with: madness, fear and violence.
Normally, we don't really try to communicate with the other species
on Earth. Animals and plants, try talking with them can be disappointing. Any life 'less intelligent' we tent to: ignore, eat, use as materials, or remove when in our way. If we discover life on Mars, as intelligent as plankton, the hype will soon be over. More intelligent life though, that we admire, respect, and fear.
So how will far more advanced aliens treat us?
I hope they are a very kind kind.
Wise would be, to not get in physical contact at first. I would not like to receive a cocktail of alien bacteria. Best is to only exchange information at first.
A space traveling kind of alien knows this of course.
ALIEN INFORMATION
It is kind of stupid to put a great lot of effort into an extremely dangerous and costly journey to an alien world, with our atom based bodies that resist against the journey (against the acceleration), to then return to Earth again. What did we gain? We gained information. It's all about information, the power of knowledge.
OK, the trip itself is something extremely impressive to do and hear about.
Also; if there are highly developed aliens out there, who have developed faster than light propulsion -a million years ago, then let's ask them if they would be so kind to visit us. That would be so much easier.
For that, we first have to get in contact, and exchange information.
And while whe are at it, I would like to ask if they know how to repair my spinal cord. See; there is some much we can talk about, without having physical contact.
Faster than light communication
Image we build a really good successor to the Hubble telescope, and see a planet that clearly has far advanced life on it. If this planet is in the Andromeda Galaxy, which is the nearest spiral galaxy to our Milky Way galaxy, then what we see is how it was there 2.5 million light-years ago. Let's send them this message "Hi there. Are you still there? Yours sincerely, people of planet Earth ". We can send this message to them with the speed of light, which will get there in.. 2.5 million years. They may answer "Yes, we are here. Do you have a better communication tool by now?" And this reply will get to us in yet another 2.5 million years, +a couple of minutes for writing the reply of course.
We clearly need to develop a faster than light communication.
And next to that: a universe translator.
Information exchange.
We, or at least some of us, invent, search for solutions to problems, try to make new things possible. But why do all that trail and error work, fight against the resistance of the ones opposing change, if that wheel has already been discovered, by another species. If we discover the existence of advanced aliens, then it is easier ask a species that already knows how to do something, how they do it.
But will they just give us the information, or will they be like us and only willing to trade it for the highest possible price?
Information is power.
Whow! That went fast!
If "they" would land in the center of an Earth town today, and stay for only a week, we will probably have learned almost nothing other than "there really are aliens, we are not alone". And most people won't believe this has really happened.
Aliens are a goldmine of information. But are we ready to exchange information? No. What we need:
- Tools to quickly communicate with aliens.
- Tools to quickly extract huge amounts of information, with and without permission.
- Tools to store, manage, and understand the information.
- Tools to scan and back-engineer their tools.
All these things should go extremely fast thus mainly automatically.
In case of an alien attack
Imagine hostile aliens, comming our way...
We must be able to:
1)
detect them before they detect us, or without them knowing we know.
2) scan them, and prevent our sensitive matters from being scanned.
3) analyze them, learn about their capabilities and weak spots.
4) adapt to the new situation, prepare strategies and means.
5) first strike, or react at the appropriate moment.
This should all happen in a blink of the eye, or we die.
At this moment we have no defense what so ever.
Let's hope they are friendly.
QUESTIONS
What would you like to ask a kind and far advanced alien?
Boy; that would be an honor. So many questions. How much time do we have?
Let's make a list. Always pleasant to be prepared.
Welcome! Did you have a good journey?
What would you like to tell us?
What would you like to ask us?
Who are you?
Were are you from?
How did you get here?
Is there a purpose to your journey?
Are you willing to sharing knowledge with us?
And are you interested in our knowledge?
Is there information that you don't want to share? -if so, then why not?
What is love?
I'm sure a lot of people would like an answer to that question.
What is life?
And probably the same question: what is
death?
How rare is life in this universe?
Have you been in contact with other species?
Have these species been in contact with yet other species?
What is all this?
How did it all start and where is it going to?
*
This should also answer the question "is there a god".
What do you think could be the optimal kind of life on Earth?
We say we don't like: war, real poverty, polution, and such.
We say we would like to live in peace and harmony.
But we keep making a mess of it.
Any comments on that? Suggestions are welcome.
What is the theory of everything?
Is it know? Is it even possible? Is there logic behind everything?
Is it in theory possible to predict everything? (when having all data and enough processing power)
Faster than light communication
We would like to communicate with other species that live far away from here, and with our own people when traveling far into space. Our current technologies are limited to the speed of light, which is way to slow obviously. Also do planets and such block our signal. Can you teach us how to get to Faster than light communication?
Traveling faster than light
Can it be done? What is space, and what is energy? Can the condition of space be changed so we can travel through it faster than light? Or can we somehow skip space and go straight to our destination? How?
And there is stuff floating in space; gas, dust, stones. How can we be protect ourselves from collision with that stuff?
I have so much more questions.
But this page is getting kind of long.
