You said in your reply to my post: "hmmm sci fi speculations. Not sure on these." That's why I asked you to clarify what you mean.
I know what the concepts mean so no need for me to look them up. — Truth Seeker
The Big Bang stories, other galaxies, and aliens ... these stories were in science magazines for teenagers a long time ago, and I used to read them with much interest when I was a teen.
Now, I am a sceptic, and tend to only believe what I can feel, think, observe and verify.
There is knowledge from over 100 PhDs that goes into making a smartphone. I don't think you are appreciating the years of research that went into developing these things. — Truth Seeker
Smart phones are just device which is slightly more clever and miniaturised Wireless radio communication device with the touch screens. Wireless communication has been available since the early 1900s, and it is not really some esoteric black art technology. Nowadays the companies have mastered how to make them smaller and also adding more extra features due to the digital technology. But the point is that these devices can be manufactured by any developed country with the available parts and resources. No need to be hugely impressed with the smart phones, broadband or electric cars ... how they work ins and outs are all in the internet, if you search for them.
And 100 Ph.d graduates in Physics and Electronics working for the smart phone technologies? But they don't know how the universe began, how and where from life originated, and they will all get old fast, and die one day just like all other humans and species on earth. What is special about them?
:D
You said: "Your sayings are like "Because we built a 300 story building on earth, we could soon build a tower reaching Mars, Jupiter even the other Galaxies."" This is not true. We already have the technology to build a generation ship. We already have the technology to go to Mars. We are trying to reduce the cost of space travel before making the journey to Mars. — Truth Seeker
That was just to give you an analogy to what you were speculating for the future from the current technology, which sounds unrealistic and far-fetched.
You send a spaceship to Mars costing billions of dollars. It gets there, and it wheels around maybe a few hundred meters on the surface, and take some fuzzy photos and send them to Earth. Take some soil samples to analyse, and then it goes to Sleep mode due to signal failure, and dies. What benefit could these current space technology bring to the living humans on earth?
Suppose you have landed on Mars. How long can you survive up there without the heavy spacesuit? How long your oxygen, water, and food supply will last? What if you suddenly need emergency surgery due to sudden medical problems? Can you even take shower? To solve all these issues, you need to transport maybe a whole cityful of gear, equipment, supplies and people with you to Mars? It is not logically impossible thing to imagine suppose, but realistically sounds too remote possibility. So where are the truths with 100% certainty you are seeking?
Do you have any formal educational degree from a university in any branch of science, such as a BSc or BSc (Honours) or MSc or PhD or DSc? — Truth Seeker
I am just a casual reader, and here to learn.
