as time ceases to exist, at the event horizon.

Thought of that a lot. How can time cease to exist? Practically whole the functionality of the Universe is based on time. Time is one of the pillars of existence. If time ceases to exist then all would be, how would I call it, static? (but you'd still exist)

Actually, time, also known as the fourth dimension, is a man made construct that we can't prove exists, probably by the very nature of our existence. We only seem tangentially aware of time because we have the ability to retain a memory of the past, so we assume a future exists as well.

This is why, at least in physics classes that teach M-theory or string theory, anything above the third dimension is unproven and not confirmed to exist. We theoretically know of 10 possible dimensions with time only be considered a quasi-dimension.

Oh, by the way, I am not an astronomer.

Albert Einstein would have loved it if he happened to know about black holes.

Energy and matter are two known principles of nature thought to be fundamental.

Time is a notion being defined by us.

A black hole is defined as having G equal to ~ (infinity) either within its Scwarzchild radius (possibly event horizon) and time is assumed to be coming to a standstill as seen from an outside vantage point. The center of the black hole is once again defined by means of it being a singularity.

Presumably the laws of physics are different inside such a black hole than outside it where everything else are being found and may be possibly observed.

Does energy by means of E perhaps cease to exist as well inside such a black hole?

Assumedly gravity by means of G is roughly proportional to mass by means of M as well.

Being able to explain and understand the principles of black holes may likely relate to the similar understanding of different theories of physics (like the the Theory of Relativity vs. Quantum Theory) relating to each other as well. For each model or explanation, one or the other theories is or are the one or ones which are thought of as being the one which fits best with observed and measured facts.

Working on it.

If mass or space equal zero do they still exist?
Is the event horizon a singularity point at which our understanding of physics breaks down?
Who knows.

But when you look at your clock, it tells time. That's reality. You can see the clock ticking, 'time' evolves

[edit]very sceptical about that string theory though...

Some would argue that the universe recreates itself continuously and the greatest resolution between one creation and the next is defined as a Planck unit of time.
If time were to stop then the universe would be frozen/static.
In a static universe consciousness might not be possible.
Photons wouldn't move.
Movement would be undefined.
I me like string theory. It hints at greater mysteries yet to come.

Ok then...

just one thing : a big ROFLMAO

Black holes are supposed to have a lifespan--perhaps a good portion of the age of the universe. They could be a portal to anything. Most interesting to me is the idea that time stops dead in its tracks past the event horizon. Actually its more like trying to explain what happens to a fraction when the denominator is exactly (not merely approaching) zero. Just because we can't define it in everyday terms, we just throw up our hands and say who knows.

But I love the whatifiness of the question. OK. Let's do the impossible, and we cross the barrier of the event horizon and time stops for us. Then in some nearly infinite time in the future as measured from the outside, we emerge.

Just a thought.

Who made that clock? Was it man made or found in nature? What is 1 second based upon that has something comparable found in nature other than a random, arbitrary measurement made by man?

Everything we know is made by us, or is at least created in our mind

Does that include the planets and the stars? Other life forms?

So... Noting that "time" is an abstraction and a concept we have created to explain how it is that "things happen"...

Does gravity need time in which to act, to exist?...


So... For the collapse of a mass to become a 'black hole', a certain time is needed:

Hence... Within the event horizon, is there a relatavistic balance maintained between gravity and time whereby the two never quite achieve the combined status of infinity for a singularity?...

Hi, ML1.

The event horizon is the point in our four-dimensional world (space) where our understanding of the laws of physics encounters the laws of the unexplained. To us there is still a difference or separation between microcosmos and macrocosmos.

Our three- (or four, including time) dimensional Universe is our rational way of looking at our environment which is a three-dimensional one. Time is a notion of ours. Gravity (which is the result or product of mass) is supposed to be bending space, making light coming from distant object reddish in color because of their relative distance as well as giving these objects a wrong or erroneous position in space than they really are. Energy is supposed to be particles which are having mass.

Yet, still energy may also be present by means of waves - something which may lead us back to the principles behind the laws of gravity.

Why are we assuming that the Universe is shaped like a globe (which is a three-dimensional circle by the way) and not being shaped like a cube instead?

Albert Einsteins Special and General laws of Theory are dealing with the subject and notion of time. Still, his famous equation E=mc2 does not say anything about neither time or gravity. This is a major disappointment and definitely something is missing here. Where is the rest of the stuff located?

Working on it.

Hence... Within the event horizon, is there a relatavistic balance maintained between gravity and time whereby the two never quite achieve the combined status of infinity for a singularity?...

I'm more partial to the notion that a Black Hole is a separate universe.
The event horizon is a threshold we can't cross.
Every event horizon is in effect at the edge of our universe.
"Beyond our universe" is undefined and the expansion of our universe is only apparent from within.
"Within an event horizon" is undefined.

Just more sci-fi gobbledygook.

Some discussions about Black Holes with the Astronomer Royal, Martin John Rees, Baron Rees of Ludlow, OM Kt FRS, to give him his full title. If you can access them, that might not be possible outside the UK. These clips are extra's to this months edition of the Sky at Night, so are up to date.

Thanks WinterKnight. Watching the videos right now.

Definitely the precence of mass is the explanation for everything we may be able to see and observe in the Universe.

Again mass is all about particles and their behavior.

Yeah who needs energy, dark matter or dark energy. It's the mass, stupid.

Please don't call me stupid.

Thanks!

Please don't call me stupid.
Thanks!

I never called you stupid.
You called us stupid for not realizing it was all about the mass, nothing else.
