Hi,

 

I was wondering if the idea Andre Linde i think, proposed about spontaneous breaking (i believe) or it may have been inflation happening at random points in space time. Could this explain the current rapid expansion of the universe, perhaps due to this type of bubble like nature..

Spontaneous breaking of what?

Severian, in physics, spontaneous breaking is a tool used to describe the splitting of forces (of nature) from their period of coexistence.

 

So, what im saying is, could this be used to explain the current accelerating expansion of the universe. It being due to inflation's of some sort, which give rise to this breaking (of the forces)...

I presume you really mean spontaneous symmetry breaking? The Higgs mechanism is an example of spontaneous symmetry breaking, in that case breaking the weak gauge symmetry. What I was asking was, which symmetry are you proposing to break?

Severian, i'm not pointing to any specific symmetry. In fact, forget symmetry breaking. Could inflation, alone be responsible for the accelerated expansion..?

 

by the way, severian, does itself (always) cause symmetry breaking...

Inflation does indeed cause an acceleration, but it is only active for the first first fraction of a second. It wouldn't work for the late time acceleration we see now.

 

I have no idea what you mean by the last sentence.

oh yeh sorry, my bad severian, of course were not in a period of inflation now, what am i talking about. i've lost track of what i was going to ask now, don't worry.

 

cheers anyway.
