Gravity is a fact. Why it happens is the theory.

Theory =/= fact. However, that's not to say that the theory of evolution can't be, for all intents and purposes, regarded as fact, but it still can't be called a fact.
Are you sure it was evolution and not adaptation?

Evolution is a fact in that it does actually happen and is an accurate description on the subject to the best of our knowledge. Yes, the exact process of how evolution works isn't 100% defined yet and is continually updated with newer information. All fields of science make sure to note the degree of uncertainty in their measurements. Even biologists make note of this in their experiments. The theory of the Big Bang is a fact. The theory of gravity is a fact. The theory of motion is a fact. The age of the universe is a fact. All with degrees of uncertainty listed in their measurements.



We've detected dark matter just as we've detected the effect of giant massed objects bending light around them from galaxies behind them that we wouldn't otherwise be able to see due to the galaxy we're looking at being in the way as predicted by Einstein in general relativity. The degree of certainty on what is causing the effect dark matter is having isn't as well known as the effects of gravitational lensing are for example. It's still a valid theory though.

Well said. Also, 9.81 m/s^2 only applies at a certain altitude. As per the inverse square law it decreases rapidly the further away you get. So there is really no "standard" gravitational acceleration.

erghh... once more, no such thing as a fact. If I can't prove for certain that your father is your actual biological father as a fact then how can you expect me to prove the big bang as a fact?

There is no such thing in science as a fact. Just the best explanation we can come up with to explain and observable phenomenon.

So unless you underwent a conversion I don't think you could actually enter the very center of it because it is infinitesimally small.

Right, that was a layman's explanation on the effects of gravity of course You act like a grammar nazi in a lot of threads. You need to spend less time correcting everyone's minute mistakes saying they left out a variable here or another variable there and just join in the discussion. We're not publishing a paper here, we're writing on a computer forum.

Actually there is. What is regarded as a fact is the most accurate description of the universe as we know it. You can't be any more certain than that.

I feel like we're playing word games though because, yes, if you want to get philosophical about it, we can't ever know anything absolutely 100%. We understand it good enough to create the computers we all use today and land a person on the moon though. We don't ever know anything for certain. We know things with varying levels of certainty and different levels of probability but it's as good as we can get it for now. You can't be 100% certain that you're not talking to a robot rather than a human typing this either.

That's one of the best things I've seen in these discussions. This isn't a peer review paper it's a freaking forum for "average" people. If we wanted to get that technical we would have a peer review paper and all of us would be informed on the subject. =)

Adaptation is evolution. It's evolution resulting in increased survivability.

ok, maybe you are misunderstanding the postulation. it's not meant to be realistic. maybe i should have started with "imagine in a world where".

I have my own hypothesis on the universe:

Black Holes are gateways to different universes. Black Holes spit out matter (matter eventually develops into planets stars etc..) on the "other" side, dark matter (current unexplained force) is also spit out from the black hole that is used as the fuel for our ever expanding universe. The number of universes are ever expanding as are black holes....however an unanswered variable to this hypothesis would be "what happens when 1 black hole eats up another black hole? Do their universes collide or join on the other side?

The universe is crazy
