Those that have seen,

The village...Will know how it reflects our planet...and the outside that we think we know...

Someone once said whatever it is, it will be a surprise...(Its not a horror film)

The Village - Those We Don't Speak Of - YouTube

The idea goes, if computing technology continues to advance at the rate it is, it would be possible in the future to build a computer that would be able to emulate (perfectly) the human mind, including conscience. Further on, you'd be able to emulate every human mind.
It makes sense, then, that the whole of humankind could one day be uploaded into some supercomputer, and carry on thinking as it did.

Now, suppose some of the computer-people became interested in history.
Without being able to "escape" and dig around for fossils or whatever, it would make sense to run a simulation (using some of the vast computing power available) of the universe, starting at the Big Bang, up until the point at which everyone ends up inside a computer.
nah we would just use perfect replica human robots that are controlled via the internet to interact with the real world, and there would be apsolutley no difference between our current interface with the world through our eyes and ears and other senses, though someones bitrate might increase as they have an orgasm.

Fact of the matter is we are already very nearly close to mimicing the human eye, we already have microphones which can outperform the human ear, and we are mastering the art of human movement, form, and sense of taste, smell, touch, and interfacing to these senses is just a commercial market away.

And people with prosthetic ears and limbs are already with us in our lives.

Quite laugably infact in regards to the human eye and ears, sure ok the eye and ears are analog but they do get converted into digital as they travel to the brain, sort of like PWM or FM and then into proteins as they are processed and stored by the brain, but the brain has thought processes that are analog too, we think and act in a hybrid of analog and digital. We have already interfaced with a mouses eye already.

Given all of this, can we say with any certainty that this (whatever it is that we're living in) isn't a simulation being run by some computer?

What would be the point? wouldn't building the actual universe be simpler? and already done...

I tend to believe that the universe had no beginning and has no end, just think about what you are saying for a second, its just like saying if there was a god who made that computer inorder to create our universe, but who created god who created our universe? it just opens up an even larger ball of string.

Its interesting to note,

That nature created electrical circuits whilst life was under water ie the brain/muscles etc...scientists think that land is required for electrical technology to be created by life forms..How would a life form that could only live in water create an electrical circuit or a computer?

The strangelet, (Just for fun)

How do CERN know they arn't making dark matter if (we can't see it or measure it)at the impact point of the LHC? What else could be formed that we don't know about?

I think they'd know if they had produced some dark matter: look at the energies of all the particles before and after collision. Use E=mc^2 on the difference to see how much mass was made. Count up neutrinos, quarks, whatever else comes out. If the sum of their masses = the energy difference, no problem. If some energy has gone amiss but there's no particles detected to suggest why, then some other matter is likely to have been created.

Regarding robots both I and some other famous mathematician or computer genius (I cannot remember who it was) have thought that we'd create a "baby" robot, give it senses, and then let it "learn". Thinking a bit more the ability to "learn" can be translated to "good"-"bad" attributes associated with actions, actions can be chosen from a wide pool, for example turn the camera in some direction, or move in some direction, and if the robot has claws for example, use the claws on some object. So there are randomising algorithms, layered memory algorithms, good-bad indicators assigned to actions before actions are taken, which can be memorised and recalled if they exist, for example if you interact with fire once your heat sensors go ballistic, so you assign a "bad" to "interacting with fire" and next time you approach fire there already is a "bad" to warn you away. Other actions start from "neutral". Some other actions also start from "bad" based on hard-coded instructions, but can be overriden if the details of the situation demand it, for example robot approaches a bigger "animate" object, so the initial indicator is "bad" (due to the size of the other object), but if robot recognises a known animate object, eg its mother robot, then it overrides the "bad" with "neutral" or "good". This is just a summary, but I believe modern PCs have more than enough power.

Additionally:

Memory would be layered with layers such as "instant-store", "processing-store", "main-store" and "long-term store". Supposing the video camera has recorded a 10fps clip, within seconds this gets copied from the "instant-store" to the "processing-store" but at 1fps and 1/100 the resolution. Within another 15 seconds it gets copied to the "main-store" at 0.1 fps and 1/1000 the resolution. And after 60 seconds it gets copied to the long-term store again losing tons of detail. Something like that.

Camera movement would also be governed by fundamental algorithms, eg turn towards light, towards movement, towards sound (based on the microphones), or towards the direction of travel. But the good-bad indicators would also come into play to override the "built-in" algos.

And the program goes around trying to find a next action to choose from a pool of actions, eg move camera, focus camera, move into some direction, move away from something, use the claw on an object, lick your fur etc

I am sure a neuro-psychologist with greater knowledge of the human mind, or a cat's mind, we do not have to start with humans, can actually describe better how the brain does it and so we can model it, or build it in a similar way.
