How is quantum simultaneity compatible with relativity?

When an entangled particle “collapses”, physics says that the other particle collapses simultaneously.

But that’s non compatible with relativity, which says that simultaneity depends on the place and velocity of the observer.

So the question is:
– How can quantum disentanglement simultaneity be compatible with relativity? Do the entanglement state is dependent on the observer, in the mean that a pair of particles can be entangled for one observer and collapsed to other?
– What experiments fundament the answer? Is the answer only theoretical?

Speed of Light and Protons

If the definition of the speed of light is for massless particles, then how is a proton, having mass, accelerated to the speed of light?  This sounds like a conumdrum.

Posted Thierence

Answer:

No massive particle has not so far crossed the speed of light. Even the extremely light particles – the neutrinos – couldnot cross the speed of light. Protons have not crossed the speed of light. When it nears the speed of light, the relativistic mechanics will become prominent and the it is to be treated is different from the classical mechanics.

Black Holes and Space

Is it possible that matter falling into a black hole would emerge in some form of elementary particles or energy in some other point in space or even time (space/time)?

I thought that matter couldn’t be destroyed just transformed into energy or some other form of matter.

Articles or theories on what happens to matter falling into a black hole say that it just falls out of existence.  That doesn’t make sense.

Responses:
“I have few knowledge about this subject, even though I think that ordinary matter when enters into blackholes may convert into darkmatter, ie energy associated with ordinary matter escapes & the matter will convert into darkmatter. From the origin of our universe this process may take place & this may be the reason that the amount of darkmatter is greater than that of ordinary matter.Here matter is not destroyed because total matter(including dark matter & visible matter ) remains constant.” … Anitha Anand (Student at university college,TVM)

Thoughts on Higgs Boson

When it is not contested scientifically that change is a continuous phenomenon,how is that Higgs boson, if found,can be considered as the ultimate building block of matter.

Sure, it may prove a mathematically arrived conclusion… yet the contradiction remains.
An ever changing, at the same time, ever stable (because it is the ultimate one) is the contradiction.
One may find changing or divisible particle only…

gravitation

The law of universal gravitation

the gravitational force of attraction between two objects depend on their masses and the distance between them.if so,the mass of both the objects is doubled.what change is brought about in the distance between them to ensure that the force of attraction between them does not change?

Space Time

Prejith asked:

What is space time?

 

Ans:

In order to describe an event, we need to specify its position in space and the time of occurrence. A four-dimensional continuum with the three co ordinates of space and time as the fourth co ordinate is called space-time.
