I am not wasting my time writing this if you like it.

Re: Mathematic complexity

THAT is AWESOME

90% of it is University Level and above, and only needed in specialised fields, such as theoretical physics.

It is a bit like looking at a map of the Universe. Here I am, here is Earth, here is the Solar System, here is the Galaxy ...

Re: Mathematic complexity

The universe is in each corner, in each atom. The infinity is everywhere.
And the mathematics helps you to understand why and how.

The infinity is also the eternity, the time without end.

Re: Mathematic complexity

Yeah, the closer you look trying to find something solid to pick up, the smaller everthing seems to be. Let us hope the quark is as small as things get, but who knows?

And you are right, you can't study much Physics without getting deep int Maths. Perhaps the next big breakthroughs in Science will be by guys just working through equations. "Hey, Harry, look how we can create artificial gravity - see here in this formula?"

Certainly the much debated "String Theory" of the Universe, and its 10 or more Dimensions is all maths.

Re: Mathematic complexity

You can say that the universe has infinite dimensions, because it is greater than any fixed counting number, or extending forever. No matter how large a number one thinks of, infinity is larger than it. Infinity has no limits.
The state or quality of being infinite is amazing, unlimited by space or time, without end, without beginning or end.

It is defined as "that which is free from any possible limitation". In other words, you can´t imagine something greater or lesser than it. It is all, and it is nothing at the same time.

It is only explainable by the mathematics.

Re: Mathematic complexity

When you sit with a nice girl for two hours, you think it's only a minute. But when you sit on a hot stove for a minute, you think it's two hours. That's relativity.

Re: Mathematic complexity

A Black Hole is so dense that its gravity holds light in.

Just like when you throw a rock up and it falls back to Earth, imagine if the gravity was so high that if you shone a torch up into the sky, that the light would just fall back.

So, if when you look at a Black Hole you can't see it  ... how do we know they are there?

Re: Mathematic complexity

Because you can see the surrounding light and matter beeing attracted by it. You can see how things are affected by the black hole's gravity, but can't see it.

Re: Mathematic complexity

I mean, if light is attracted by black hole´s gravity, why can´t you go faster than light?

Re: Mathematic complexity

I thought there was something about time being slower when you were sitting on the edge of a black hole (presuming you could)....was that just rubbish?

Re: Mathematic complexity

I think that if you got sucked into a black hole and survived, you would go back in time or something, that's my theory.

Re: Mathematic complexity

Yes, but are not able to survive, because a black hole has an amazing des¡nsity (a lot of mass in a short amount of volume), so you might desinteger.
I think that in the center of the universe is a giant black hole that is consentrating all the mass. And as stars, it explodes making possible space and time. The last time it happened was in the "Big Bang."

Re: Mathematic complexity

The density of a Neutron Star (which is not as dense as a Black Hole) is so high, that one teaspoonful of it would weigh about 100 billion kilograms, or more than 1,000 Titanics.

Speaking of which, what would happen if we were in a car travelling faster than the speed of light (yes, I KNOW it's impossible) and we switched on the headlights?

Re: Mathematic complexity

Well, from the car's perspective (ie as a passenger) you should see the headlights beam cast forward, I think. But an onlooker would not, or something, I think. ... umm ... I wish Einstein were here!

Re: Mathematic complexity

My theory is that since the car is faster than the light, the light wouldn't be able to keep up once it erupts from the bulbs (but keep travelling in the direction of the car)  and simply fall back, so the car would create a trail of light like a comet.

Dragging Space and Time

The results of two studies announced in early November 1997 provide unprecedented support for “frame-dragging,” a concept predicted by physicist Albert Einstein's general theory of relativity. Frame-dragging describes how massive objects actually distort space and time around themselves as they rotate. One of the studies examined frame-dragging around black holes, an example of which is shown here in an artist's conception.

Re: Mathematic complexity

When you say "time," what do you mean? I understand how space can be dragged into a hole, but I don't understand how time, the thing that passes us for ever, can.
