A few questions

[Willis666]

Hello guys, and let me introduce myself. I am a 15 year old boy who has been studying Physics in my own time since age 9. I have also been learning to program in PHP since age 11, and recently decided to make a MMO in PHP, based in the Universe, called Spacetime online. The game is based after a strange happening, 20 years in the future, when many large stars collided, and created a giant mega-star. My first question, would that be possible? If so, then continue. The next thing that happened was that caused a huge supernova, that created a giant black hole. That destroyed most of the universe, except for a small spot in "corner" of the universe. This spot was where humans who escaped the earth (which was destroyed from too much pollution.) Went, where they created a colony on sattelites. Humans then learned how to "harness" dark matter, and thousands of scientists where sent out into the then empty space to recreate the universe (we can just say that the black hole destroyed itself :P) My next question is how (in the future) Would humans harness dark matter? May be difficult to answer, as we arent sure what dark matter is yet (of course we will discover some more soon, as thats what spaceshuttle endeavor was going to do...) Finally the game is based where players may go around, "spending" dark matter to recreate the universe. So really the game is just a endless "grid" where players can build universes, stars, etc. And players can interact with player created objects.
Thanks if you can answer any questions. I know I'm being unrealistic on some of this stuff, but I probably wont have many people who understand this playing the game.

Thanks for any help.

First of all, as long as this is merely a science fiction scenario, I doubt people will care about what is correct / incorrect. If you really do care though I might add a few things.
1. How did these large stars collide? You need a backstory to that because unless galactic canabalism is occuring, stars generally don't just "collide" with eachother. And if it was galactic canabalism, the biggest of the 2 super massive black holes at the center of the galaxies would be exponentially larger than anything that could be created by a few large stars colliding.
2. If in fact a giant black hole was created, it would literaly have to be so freaking huge that it could destroy most of the universe. I'm not going to do the math behind that but I'll just let you know that if you wanted a black hole that swallowed up even 3% of the universe, it would need to be so large you couldn't comprehend it. So be careful with coming up with one that swallows up OVER 50% of the universe.
3. The black hole, being as large as it is, would not let that "small corner of the universe" survive for very long. It will continue to expand. Fast.
4. You should change it so that scientists learn to harness dark ENERGY instead of dark matter. I doubt dark matter would do much for them. Remember, dark matter only accounts for about 23% of the total mass energy density of the universe.
5. The game idea sounds really cool. Kind of like a garys mod for cosmology with a mmo aspect to it. Don't go overboard with trying to make it so real. Its more fun when its crazy anyways :P

Thanks, yeah the part about the giant black hole is stretching it, should I do something more like they discovered a way to recreate the big bang and create a multiverse? What I want to do with the game is make it so players can make the game themselves. I could also see some sick guild battles going on, over control of series of areas.

Is the destruction of the universe necessary? Sticking with the black hole theme you could start with something along the lines of; in the not too distance future mankind creates a massive particle accelerator. But something goes wrong and they create a black hole that starts devouring the Earth. The few colonies located around the solar system quickly descend into economic disasters and war, a few intensive engineering efforts through generation ships far and wide in an effort to avoid the turmoil of the solar system. This is the story of one of those ships...

That way you can get away from Earth in some remote part of the universe and perhaps have the generation ship discover how to use dark energy on the way

I prefer this plot, it rolls easier with me.

I don't see what purpose destruction of the universe serves. It's a blank canvas either way, but ryan's method allows you to save a lot of ridiculous explanation.

Thank you :biggrin: unfortunately I'm not much of a writer but perhaps our OP can garnish us with a good yarn eventually

You would also have to explain how humans managed to go to the small edge of the universe in a manner of time before they all died of age. Maybe the various wormhole metrics were actually describing tangible things in the universe?

Even if wormholes were to be real enough that we could create a pair we would still have to drag one sublight to the desired destination. Perhaps if these humans found a way of cranking a space habitat up to .9999999.....etC they could cross the distance in a matter of subjective years. Need a hell of a radiation shield though, not to mention propulsion issues

I like your idea ryan, and since this in the future we can just say that they created forms of transportation able to travel that distance in matter of minutes.
Time to get coding! sorry I havent replied for a while, I was working on the basic engine.

Here's a ship for you: http://andromeda.wikia.com/wiki/Bellerophon

It's called the Bellerophon and is from sci-fi Andromeda.

It's basically a massive engine that humans created, travels near the speed of light and the crew experiences the effects of time dilation at those speeds (they travel for a few days near light speed and months/years pass in real time - or whatever the conversion is).

It's just something for you to consider. It's a way of getting around for them that doesn't violate any physics.

Thanks, but I think I have it.
