Are all known stars supposed to be in the game?

The problem is, we're under the impression that the laws of physics are set in stone. For all we know, our laws don't apply to the rest of the multiverse.
Aside from the fact that we're thinking that space travel is delimited by machines and bound by time.

Perhaps all they need do is 'dial in' a location.. and blam... they're there.
I've seen enough weird flying objects over the course of 30 years of observing the skies methodically to be absolutely certain that we aren't alone. But that's for a different forum.

I once saw something very curious while out stargazing - enough for me to believe that it simply could not have been man-made.

But when you really think about these things...why would far more advanced aliens - who are supposedly trying to hide from us - use simple visible (to humans) light on their craft? Why not infrared or something else? What purpose do these lights serve anyway? It makes no sense.

It's also about timing. If a civilisation in the Milky Way discovered Radio 600 years ago and made broadcast transmissions for 100 years before, as has been mentioned, they started to use other, more subtle methods of communication - so far so good.

Now, what if that Civilisation lived 300 light years away?

We've already missed that show.

The chances are extremely remote for us to communicate with alien life even if it exists and has similar technology to us. The universe is huge and light is very very slow.

But why would they choose to stop sending out radio waves as a means of communication when that's what they did for themselves? It's fine to assume that there may be other - better - methods of communicating with nearby aliens, but why stop doing what they did to start with when other nearby species might have done the same?

And the same goes for listening - we will continue to listen for radio waves even though we're largely past that phase, the reason for which is the same as above - other species might be broadcasting in radio, just like we did.

And again, *all* of them would have to make the decision to stop sending out radio waves. If just one passes through the net then the game is up. Our transmissions are out there, waiting to be heard, and there's no bringing them back. Are we the *only* ones who did this? This is the crux of my issue - these type of assumptions are even more fantastical than the simple answer of us being alone.

What I want to know is are the stars from Frontier in the game? Actual genuine stars like Barnard's Star and Sirius?

Sirius and Barnard's Star are both there, and quite close neighbors to SOL (aka Earth system). In fact, these two stars I paid particular attention to, as well as Alpha Centauri in a science video I did looking at star positions relative to their real world constellations. Check out the TY Video earlier in this thread, and learn more about Sirius and Barnard's Star as accurately represented in Elite: Dangerous.

Also, SETI is a research project based on a the "Drake Equation" which describes how likely it is to find civilizations that can be detected by radio waves.

The equation:

N=R*FpNeFlFiFcL

N is the number of detectable civiliations
R is the rate of stars suitable for life
Fp is the fraction of those stars with planetary systems
Ne is the number of planets, per system, with an environment suitable for life
Fl is the fraction of Ne where life actually forms
Fi is the fraction of Fl where life develops intelligence
Fc is the fraction of Fl where intelligent life develops civilizations that release detectable signals into space
L is the length of time when a civilization releases detectable signals into space

There is a large hidden assumption in L - That the length of time they transmit also coincides with the length of time that we would be surveying to detect it.

At the end we end up with a stupfyingly low number of detectable systems - but it's not zero, at the very least the result is One (e.g. Earth)! Also, the equation takes a lot of assumptions to construct, such as, what value do we plug in for Fp, Ne, Fl and the others? Messing with the numbers could yield results that say we are the only civilization at this time that emits detectable radio signals in the whole universe at this moment, meaning we will not discover any other life this way. Alternately, the equation could yield a result that says many such civilizations are out there, and we just haven't stumbled onto them yet, or if we have, we haven't distinguished their signal from background noise.

It's a huge debate based on a solid mathematical foundation - but so many variables have assumed values that could easily be proven wrong.

Why space remains silent after decades of radio astronomy is for me the BIG mystery. There are all sorts of explanations. But that's all what they are... speculations. "Still think we are alone?" It's improbable but not impossible.

Well there was the Wow! signal:
