Physicists confirm thermodynamic irreversibility in a quantum system

loved this one! ;)

I used to think I was half way smart until all this stuff about quantum physics came to light. But you don't have to understand it to realise it's true.

You are not alone. Einstein himself disliked it, although he started it with the idea of a photon being a particle, after behaving as a wave. But he also started a new field with the Einstein-Podolsky-Rosen paradox of 1935. Now people like Maldacena propose entanglement as the basis of the structure of space-time. Einstein would be horrified. God does not play dice, he said.

The launch of LISAPathfinder, rescheduled for 4:04 GMT today, was a success: the satellite is now happily cruising towards the Lagrange point L1 which it will reach in two months. Next will start the scientific phase of the mission.

No, he doesn't play dice, he is the dice.

God cast the die, not the dice. Cited from the book "Albert Einstein creator and rebel" by Banesh Hoffman and Helen Dukas, former Einstein secretary.

Measuring Entanglement Entropy

It seems like quantum entanglement lies at the basis of our collective consciousness.

THE THIRD STATE - TOWARD A QUANTUM INFORMATION THEORY OF CONSCIOUSNESS

“Consciousness science will remain in scornful isolation until we accept the fact that the brain is classically finite and move on to the important question of why it is so"

“To deny that the brain is a affected by quantum processes is as it is to deny that the Earth orbits the Sun”

ABSTRACT
:
The question of how our perceived reality is constructed and
subsequently how our mind has evolved such that we are able to both perceive
and subsequently alter our own causality or even our own evolution within this
reality has been a long running open question

Isn't this another attempt by philosophers to infer that we only are because we think we are, or some such stuff. Next they'll be saying we can cease to exist in a puff of smoke if we turn ourselves off, or believe we don't exist any more.

I'll take a rain check on that please :-)

Fair enough.

Read two books by Roger Penrose, "The emperor's new mind" and "Shadows of the mind". I've had an exchange of letters with him. He is a very nice man.

I was just thinking last night about the Big Crunch scenario. The universe would collapse into a singularity due to the gravitational pull of all matter. How is that possible when we know about the existence of dark energy and what it does to the expansion of the universe? We also know there is only 4% of regular matter in the universe And also knowing that gravity is the weakest force of the the 4 forces we know of, the theory just doesn't make sense to me.

'It is said' we cannot account for all matter in the universe so we might have to consider the universe's escape velocity as well, which is still unknown at present..

4% normal matter
over 80% dark energy
+/- 25% dark matter

Can there be a conclusion drawn with the above info?

The big crunch has fallen on disfavour. The going theory now is that the universe will keep expanding for trillions of years and eventually dissolve to nothing when the last atoms decay and break apart. Personally I don't think anyone really has a clue regarding the eventual fate of the universe.

That is what I believe (Big Freeze), thank you for the heads up Bob.

No current scientist has the faintest cue about the universe Bob!! They all go to Uni and get PhD's with their theses because nobody can disprove what they say.

Maybe the bible, written under the guidance of ET, got it right.

.. As it was in the beginning, is now and ever shall be, world without end.

Too much pressure on 'em I say..

I heard Carlo Rovelli, a theoretical physicist working in France, speaking on the Italian Swiss Radio about the number of mistakes Einstein had done in his career and how he had always corrected them. He had inserted a "cosmological constant" in his equations of general relativity to forbid the Universe from expanding, then took it away when Hubble and Lemaitre demonstrated that the Universe was really expanding and called it "my biggest blunder". Now that constant is interpreted as the energy density of vacuum.

It's a fact that our universe is expanding into something.
On the other hand scientists says that our universe is infinite.
Measurements have been done by making huge triangles using the WMAP and checking the angle sums.
They all show that the sum is 180 degrees which means that our universe is flat and therefor infinite.
Does this make any sense to anyone?

No more than anything else that is beyond my comprehension. For now I will take their word for it, that is until someone new comes along with a better and completely understandable explanation.

The universe is putatively expanding but it is not expanding into "something" There is no other "something", only what is currently existing. Think of a spherical balloon surface. This is 2 dimensional--assume a 2 dimensional world --it expands as it is being inflated by creating more 2-dimensional surface area. There is no 3rd dimension in a 2-dimensional world just as there is no 4th dimension in a 3 dimensional world.

I say the universe is finite and unbounded. The fact that we have not seen any curvature is probably due to the fact that we cannot establish a long enough base line that is not itself affected by the curvature due to what we call "gravity"

if you continue to say that...maybe you'll also, alongside me, be called upon making this forum secular!
:D :D :D

but yes, I think you're right about that!
