Are there any good space flight simulators with hypothetical space craft with realistic physics?

Do "construction" games like Kerbal Space Program have that?

Orbiter. It's free, too.

Many great videos on YouTube showing just how flight simulatorish orbiter really is.

You spend a lot of time figuring out how to time burns to manage your orbit.

I don't know if the physics are realistic, but Elite: Dangerous is the closest thing to a space flight simulator. Distance wise it's realistic at least, in that even with FTL speeds going 300x the speed of light you take forever to get to another planet.

The flight model in Elite is very much tuned for fun rather than accuracy. You can if you wish turn on a kind of newtonian physics flight model, but even then I very much doubt its representative of how actual objects in space would react.

Another vote for Elite: Dangerous.

By default you get a "fighter-jet" flying model, which is an easy and necessary toggle to full Newtonian physics as the situation merits.

Your first line and third lines conflict with each other. AFAIK FTL travel is not possible.

I am working on exactly this with an engine I have developed in my spare time. So far, I have implemented a realistic physics model for both flight through a fluid (based on stability derivatives, much like Flight Simulator) and for space travel (currently Newtonian). Although I hope to one day support a large procedural universe, currently only a Terra type world with an Earth-like moon are supported.

Awesome. Looks promising!

Along with the other suggestions, there's also "Rogue System" which is a sort of "hard sci-fi" simulator/game. However, development has unfortunately stopped due to the developer suffering an injury.

Kerbal does sound like it'd be a good match for what you are asking though; It's not perfectly realistic but probably the best (only?) combination of all aspects - from building to launch to space manoeuvres to re-entry - and there are plenty of mods for making things more hardcore-realistic (planet gravity wells, reaction wheel saturation, angular momentum, signal delay, life-support, better aerodynamics).

There's Spaceflight Simulator, which is for Android and iPhone. It is a 2D representation of space, which simplifies things a bit, but you still get all the orbital mechanics.

The space flight simulation/orbital mechanics in KSP is very good/realistic, miles better than anything else out there anyway.

and you can mod n.body and real universe in it:

getting them all to work together might be a little finicky, for a realistic simulation I'd go just with Principia, as the compressed distances and smaller forces seems to help a lot with game stability

Independence war 2 is the closest I've played.

SimpleRockets 2 is a space flight simulator
