Do you think that the universe is infinite?

@Experienced33 and that definition is... what?

@newjaninev2 the universe

I think everything that has a beginning has an end. So no in relation to time.

@Experienced33 That’s merely a tautology. You’re saying that the universe defines infinity and the universe is infinite. You’re saying that the universe is what it is.

@newjaninev2 If it ends, what is beyond that?

@Experienced33 The universe is expanding, and it is that very expansion which allows spacetime. There is no ‘beyond’, because the very concept relies on that expansion... in the same way that it is meaningless to talk about ‘before’ the Big Bang

@Experienced33 Exactly. It has to be infinite.

@newjaninev2 You've been doing your homework ma'am.

@newjaninev2 Relativistic Spacetime is not a very intuitive concept for a lot of people, although is a scientific fact.

@CharlieZ I find that the limitations of language, and a failure to begin with definitions, cause a lot of misunderstandings in these discussions

@infiniterealism I occasionally spend time with physicists, and they have been kind (and tolerant) enough to help me with basic principles. Unfortunately, I know little beyond that... but what little I do understand is mind-boggling

@newjaninev2 Good point. It seems like you have been reading on this subject.

@newjaninev2 You are right, of course.
But, IMO, some naturalized hidden assumptions, "common sense philosophy" and the discourse they call "logic" play a role even higher than a poor languaguage.

@CharlieZ I agree... one so often hears ‘After all, it’s just common sense’

It turns out that common sense doesn’t help. actually misleads, and blocks understanding of the evidence (as in so many things)

@newjaninev2 Albert Einstein: "Common sense is the collection of prejudices acquired by age eighteen"

@CharlieZ Oh, I didn’t know he’d said that... but it’s lovely!

@newjaninev2 It IS!
Dear Albert never deceives!

@CharlieZ and also, of course: "Two things are infinite: the universe and human stupidity; and I'm not sure about the universe”
[i]Albert Einstein[/i]

@newjaninev2 His concept of an "infinite" Universe was not at all the clasic pre Relativity one.
What this debate lacks is a concept of Physics: what is a Field.
Our Universe is a gravitational dense field.

Is interesting how a previous born debate (the wave particle duality) leaded to the assumptions of the "failed" Michelson & Morley experiment.
And how it´s results, the vanished conjecture of the "gyroscopic" Aether leaded to the formulation of Special Relativity.
And to the Einstenian concept of Space as a Field.
