Instead of waiting until something is economically viable before making an attempt we could make the attempt and in so doing make it economically viable.

Yes that's exactly what we need to do. It's years and years of attempts, failed missions, successful missions, research, practice that will get us there. It will never be economically viable if we just wait.

For example, if it takes 6 months to learn to ride a bike, you don't wait 6 months and then ride it. You actually have to practice for the whole 6 months.

nec209 and Ken Fabian seem to think we just have to wait a few hundred years and then the knowledge and expertise for economically viable space colonization will just appear. We actually need to continue what we're doing at the moment and eventually we'll get there. What's the problem with that?

I don't resist junk food. I'm too skinny.

I don't think much of anything we do in space will prove easy, simple or cheap. The great risk is that, despite their abundance, space mineral resources will be not be economic to exploit. But that initial push, how big it has to be to carry it past being a subsidised burden and into self supporting and how that can be achieved is what still concerns me. I'm a long way from convinced there is any real prospect of it in any near future I can envisage.

Obviously it wont be easy or simple but I guarantee it will be cheap. Surely you agree its feasible that there will be enough technological advances to drop the price of space travel by just 1% within 500 years? Then a further 1% every 500 years? That means it's conceivable that space travel would be 99% cheaper after 49,500 years! Personally, I think this could be done within 300 years but 49,500 years would guarantee it.

Back in 1943 the president of IBM, Thomas Watson said "I think there is a world market for maybe five computers". The idea that there would be about 2 billion computers by 2017 was inconceivable. Impossible. But it happened. There has been huge advances in technology during the last 100 years and it's speeding up. Space travel is inevitable and it will be common place. Summer vacation, school trips etc. Visiting another planet will be something people take for granted. Inconceivable in our life-time but inevitable in the eventual future.

The propulsion system for such cheap space travel hasn't even been conceived yet. I cant even begin to imagine.

Download and install Malwarebytes. Click Scan, select Custom Scan and select the whole C: drive. Also select rootkit scan.
If it finds anything, click Quarantine Selected. Restart the computer.
Do another full Malwarebytes scan, if it doesn't find anything, your okay. Otherwise, Quarantine anything it finds, restart and do another full scan.

When you're finished with Malwarebytes. Download ADWCleaner and so a scan. You only need to run this once.

Next, do a FULL virus scan with your regular anti-virus software (not a quick scan).

Uninstall any other software that claims to remove malware etc as it could be fake software.

So my seniors on in college recommended C++ and PHP. They said the Adobe version for C++ is good (either it was adobe or ado). So where on the net can i get both?

 

Thank you!

Download Xampp and play around with PHP. It comes with some example code which will give you an idea how it works. Your understanding of HTML will help you because PHP is outputted to the browser as HTML. Try and modify the code and experiment with it. Also you could by a PHP book on Amazon.

Actually, Windows 10 is now free to use. The only thing you can't do is use the desktop theme customization features.

Windows 10 is only free for use with screens smaller that 10 inches such as tablets.

For larger screens, Windows 10 isn't free and never has been. When released in July 2015, Microsoft were offering Windows 10 as a free upgrade to Windows 7 or 8 for a 12 month period. It wasn't technically free though because you were required to own the licence for either Windows 7 or 8 which costs money. Without this, you couldn't legally download Windows 10 without paying for it.

Hearing or visually impaired people who own a license for Windows 7 or 8 are still entitled to the free upgrade to Windows 10 for use with assistive technologies but this offer may be cancelled without notice. Again, the Windows 7 or 8 license is required to subsidize the cost.

It's possible to download and install Windows 10 and use it without paying for it but its theft. The idea is that you pay for it. It's like saying food at a restaurant is free because you could order a meal, eat it and then walk out without paying for it.

So we don't have to be millionaires to go to moon or mars? It some thing the middle class and lower class can pay for?

That's correct. Only the upper classes could afford to fly when passenger planes first started. Flying was so expensive. Now anybody can fly.

In 500 years, I think the middle classes could afford to travel to mars.

Overpopulation ?
That's not why we went to the Moon, or need to go to Mars.

Canada has 33 Million people.
And 95 % of those people live on much less than 1 % of the land area.
Land which is way more hospitable than Mars.

And I'm not including vast areas of North-Eastern Russia, most of Western Australia, jungles of Brazil, pampas of Argentina, and all of Antartica. Heck, even the bottoms of shallow seas/oceans are more hospitable.

We have proven we can get to the Moon.
We need to prove we can get to Mars/other planets.
When the cost/benefit ratio becomes favorable ( in terms of resources ) people WILL go there.
But, other than bases, for staging/exploration/resources, we will never have permanent 'settlements' there.

So Canada will still have land available in 50,000 years? The human race should still be around in 10 million years, 20 million years, even 30 million years. Space colonization is inevitable. 

Dinosaurs were on earth for 165 million years before they got wiped out. Maybe human's could beat that.

in my everlasting arguments with a creationist, i thought of something that i wonder and cant find anything using google, so want to ask here.

we all know about fossils of dinosaurs ect, but how about fossils of the animals we have now?

for example, have we found fossils of kangaroos, koalas, bears,possums,lion beaver elephant, exactly or almost the same as they are today?

if there are none, wouldnt that mean creationists have a hell of a lot of explaining to do to have a completely different set of animals now to millions of years ago?

if anyone knows either way, please provide link if possible.

It's pointless arguing with a creationist, the truth doesn't matter anyway. The only facts we know for sure are that countries focused on science work together. Countries focused on religion kill each other.

Surely god would want us to believe in the big bang, science and evolution if it brings peace? After all, peace is mentioned a lot throughout the bible.

Or you some how thing there is going to be technology breakthroughs to bring space cost down to say $500,000 space ticket per person to mars or the moon?

The cost will drop significantly. Within 500 years, it will be like buying a plane ticket for a trip during the summer holiday. It you think that's a little optimistic, definitely within 1,000 years.

I didn't really understand your question. And shouldn't it be the other way round, that virtual games imitate (or should I say recreate) reality?   

I was referring to the similarities of how it works in the background at the quantum level. To me, it suggests that the universe may be running on a computer. Especially being such a mathematical universe.

The primitive urge to seek new and better horizons and leave intractable problems behind rather than face them.

The popularity of science fiction that tends to downplay or completely bypass - by some imaginary tech brilliancy - the extraordinary costs and difficulties.

The illusion that it would be a lot like the successful historic colonisations that happened on Earth.

The false expectation that ingenuity can overcome all limitation.

The belief that it will be not just economically viable to do so, but deliver enormous economic benefits.

The belief that space colonies can provide enduring security and defence from existential threats.

The unlikely expectation that humans in space will enjoy greater freedom from regulation or societal constraints.

 

Yes you successfully listed some of the negative aspects of space colonizasion and none of them involve war which is a very good thing.

Space exploration leading to colonizasion is the eventual result of a science driven civilization. Countries across the world working together to cover the huge costs.

The alternative is a religious driven civilization where countries anialate each other.

Yes exactly, and North Korea. I would love to see every country work together. There would be an end to war and we would be able to look after our planet a whole lot more. Once we can do that, we can colonize another planet without making the same mistakes.

There is not a day that goes by with out the media going on and on about going to the moon or mars!!!

Well it serious not going to solve problems of colonization of the moon or mars. It not going to solve overpopulation problem.

It not some thing the middle class can have enough money on one way ticket to the moon or mars. Even the upper class will not have the money for a one way ticket to the moon or mars. So it not going to solve the overpopulation problem.

What is with the government and private sector pushing this trip to the moon or mars in 10 to 15 years. When there is no spacecraft that cost effective?

Any spacecraft they have and in the research and development is not cost effective for the upper class that alone the middle class!! It cost way to much money going into space.

Why such a push for space colonization?

I'll take two quotes from you - "space colonization" "cost way to much money". That is the reason why it's a good idea, you answered it yourself. No single country can afford it so instead we all have to work together to share the cost. Here's a list of countries currently involved in the International Space Station

Canada
Japan
Russian
United States
Belgium
Denmark
France
Germany
Italy
The Netherlands
Norway
Spain
Sweden
Switzerland
United Kingdom

Expensive and difficult to achieve projects like this and CERN bring countries together. Science brings countries together.

Let’s start with a primer to some of the techniques used to maintain an optimal frame rate when displaying computer game graphics. Games consoles such as the PS4, Xbox One and PC aren’t powerful enough to render a whole city in 3D. Instead, they only render what’s currently onscreen. Furthermore, only the camera facing sides of objects are rendered. The sides you can’t see only exist as calculations without any substance, ready to be rendered as your character moves through the game. This process is called hidden surface removal. Sometimes, objects are removed from view completely, like if a car drives past a trash can, there’s no need for the trash can to be rendered while it’s obscured from view. This process is called occlusion culling.

Now back to the real world. The Double-slit experiment first performed in 1927 by Davisson and Germer showed that light and matter are waves, yet become matter when observed. Science can’t answer why quantum physics behaves this way. The only explanation that comes to my mind is that it’s to save processing power.

To quote Galileo Galilei “Mathematics is the language in which God has written the universe”.

A mathematics driven universe is perfect for a computer.

If I was god, I would have created a load of fossils and hid them in the earth for somebody to find. When I created the zircon rock and the Canyon Diablo iron meteorite 6,000 years ago, I would have made sure that the radiometric readings make it look like it was 4.543 billion years old. I would have set the galaxies on an outwards trajectory to make it look like a big-bang happened. I would have created a beautiful cmbr to add further evidence of a big-bang. Seriously, why not?

I'm a man of science but a creationist can always say that god created it that way. Even if we invented a time-machine, went back 13.772 billion years and filmed the big-bang using a GoPro, creationists can say that god created the past when he created everything else 6,000 years ago. There's never an argument, creationists will keep on believing regardless of scientific proof.

Before anybody comments, I know it's not possible to actually film the big-bang.

I like to think this is more of a hardware issue, and more specifically a chemistry issue.

 

Do the busses in the motherboard just wear out over time due to constant current? CPU eventually warps over time?

 

I dont know much about computers, so sorry if my theories seem really fundamental.

A software issue is the most common fault with computers but lets focus on hardware issues. A popular cause of hardware fault is dust build-up - The fan sucks in dust which clogs up the heatsink which impedes the ability to keep the CPU cool. A CPU will fail when it gets too hot so there's a thermal safety feature which causes the computer to switch off when it reaches a certain temperature like 90°C. Obviously fans can fail as well which will cause the computer to overheat etc.

To answer your question properly, I'll focus purely on the hardware without any external influences such as software, dust, power surges, fan failure, manufacturing defects, human intervention etc.

Imagine a computer in a cleanroom environment. What could cause it to fail?

1. Electrolytic capacitors can fail.

2. A computer gets warm when you switch it on, cools when you switch it off, gets warm when you switch it on, cools when you switch it off. All the metal parts are expanding and contracting, expanding and contracting. Some metals expand more than others due to differences in the forces between the atoms. Solder joints get weak etc. A computer should actually last longer if you never switch it off because the metal wont contract.

I'm ignoring hard drive failure because that's not computer failure. My first computer didn't even have a hard drive.
