Do you think that the universe is infinite in size?

We can't see anything further away than 14 billion light years, right? So we are within in a sphere of that radius, hence finite, would be my first guess.

But yea, if the laws of Physics have changed over time, allowing faster-than-light expansion, hypothetical universes could be as large arbitrarily large and still appear to be within that sphere in relation to us. But to have an infinitely large universe from one big bang would need expansion speeds tending to infinity as time tends to 0, which is probably OK so long as you don't actually care about what happens at that "time 0", it just makes that singularity slightly more obscure...

Have any of you people heard that the universe may actually be a giant electron?

Here's a quote from Carl Sagan's Cosmos series:

"I think" it's infinitive.

If it is not possible to travel time and time moves always forward,
then the concept of time would have to take on more meaning,
we have discovered new things that can move faster then light, yet I do not think they are actually moving faster then time.
even though things move faster then our concept of time does not mean its moving backward in time.
perhaps slower or faster relative to the gravitational forces and object mass in that given section of space..

One of the reasons I was mentioning black holes ( as worm holes in space) was to see if we can compare
time zones but as a liquid reality then just 3 dimensional space, to contemplate time in this manner,
would it be possible to actually travel time this way, it seems like it would but I do not think so, somethings wrong,
if we can do it then so would the whole universe as it collapses in on its self and jumps randomly forward or backward in time,
to me its not vary realistic to think our universe is stuck in a time loop repeating its self forever,
along with us in it.

Its hard for me to believe that all existence just began in one big bang where an infinity before nothing existed.
this tells me that it either has to collapse in on its self to recycle, or there are more of these big universes out there
that eventually shares materials with others, about like an atom shares its electrons with another atom,
just on a much larger scale, or they can and sometimes do both.

the problem with big bangs and starting over is that some materials would be lost each time until it became
just the right size, or it began just the right size to begin with, and if we are losing materials then where does it go?
what becomes of it?

I think it just keep moving forward in time recycling its self,
each time being different then the last, not repeating its self,
with other close by universes as well doing the same thing and
sharing materials now and then.

here is a thought,

if universes are like atoms, then after a point they would become stable and exist until something changed it.
we may be at the beginnings of a new atom, where stray energies like electrons collided, creating life.
