When singularities collide

Scary stuff!

I wish I was around when those grav waves hit us. I've always wanted to see the inside of a black hole, even though infinite gravity wouldn't feel too good.

I have read about that too. It just sucks how far away from us any stars are, and especially those two black holes that one day will release a lot of energy in their galaxy. But that will take another ten million years or so, we will never know. Though astronomy is definately a fascinating area. It is based on more theories then laws that are known to men, but still is f*cking fascinating.

and what is cool is......if you only think about what has happened to man in the last 100 years.....it wasn't that long ago that powered human flight was only a theory, and after the wright bro's showed the world it could be done.....it was a mear 62 more years and we put a man on the moon.....pretty amazing stuff we can do when we put our minds to it.

there is a LOT of stuff out there that is NOW considered Sci-fi, and most of it is based in some existing theory, pretty neat stuff when you think about it.

There is absolutely nothing wrong with theories! A misconception about this term seems to suggest that a "theory" is baseless. In actuality, scientific inquiry follows a hierarchy: 1) a "Hypothesis" is proposed, which is generated from observations of a physical/chemical system. The hypothesis (or several hypotheses) is created to formulate an explanation of some system. Then, a means to test the hypothesis is proposed. 2) Only if a repeatable set of experimental constraints supports some hypothesis does it have a chance to become a "Theory". To be repeatable, any scientist must be able to replicate the experimental results and/or use this methodology for prediction of future experimental results. There is scrutiny and challenges placed upon any theory from the scientific community. Furthermore, a theory is never proven, instead, it is continually challenged b/c science must always inquire!
3) "Laws" are quite rare, yet, often there still remains challenges.

The beauty of science is the advancement of knowledge and the realization that our understanding of the world/universe does indeed change over time. The use of "theories", as a organized set of rules to be questioned, tested and supported (or not) helps propel us forward.

The reason why I respond is b/c I cringe when I hear folks make such remarks as: "Evolution is just a theory". Yep it is, and it hasn't been discounted yet, not to mention that the preponderance of data indicates, that yes, over time, systems do indeed change (evolve).

Thus, having an explanation based upon scientific "theory" is much more sound than only having "faith" that a particular solution is real!

And when you're looking at the star you're looking at how the star looked liked several million, and even billion years ago. Because it takes that many years for the light emitted to get to our eyes. The star you look at probably is much more brighter today, or even has already exploded in a supernova, and doesn't exist. In other words, you're looking into the past, Fascinating stuff.

And if someone on a planet orbiting these distant stars saw Earth, they wouldn't see us, but rather probably dinosaurs instead.

Unfortunately, the general public RARELY ever knows the "truth" about these things.... since they are VERY complicated by nature.

All the news people can say is "a big meanie comet wanted to hit us, but our superhero scientists were too nice to let that happen so it's gonna miss by a really big distance "

the truth is out there

and this is the point where the brain capacities of our fellow protege owners get completely overwhelmed by the intricacy of astrophysics.....
