@Mordred When I asked you about conformal time as the age of the universe, I meant conformal age of the universe, even if I didn't specify it.

This one https://en.wikipedia.org/wiki/Lambda-CDM_model#:~:text=the%20above%20has%20an%20analytic%20solution If you also know the explict function which doesn't neglect the radiation density, I'll be grateful if you share it. The radiation density is so negligible (even if it wasn't in the very early universe), that the integrated inverse of the scale factor function without it also gives 47 Gy and 47 Gly.

@Mordred conformal age is on the LHS, and the upper limit of the integral on the RHS is the proper age.

I did, because 13.8 Gy is the proper time of matter.

@Mordred η=∫dη=∫dt/a(t) If you do this integration with bottom limit equal to zero and upper limit equal to 13.8 billion years, you'll get 47 billion years. If you multiply this result by c, you'll get 47 billion light years.

@Phi for All Jesus... I think you forgot to add all the banned users to this list to make it more impressive. It's not infinite though. Why haven't you banned me yet?

Now the funniest thing. If cosmic time actually is the conformal time according to @Mordred and my physical definition for this time, is 47 Gy a present, cosmic time of the universe? What's your answer, Science Forums?

That's a good one :) I really like it, seriously. In a sick world you have be a psycho to be normal.

Thank god for that @Mordred .

@Phi for All I wasn't banned on Reddit's r/Astronomy for evading a ban, arguing with them or insulting anyone. I was banned for telling them they created a cancel culture, and I gave the explanation. They couldn't handle it. I couldn't even argue with them afterwards, because they muted me right away. You know exactly why I'm calling @Mordred a liar. Go ahead, ban me, you're great at it giving 40 pages of banned users. I don't care. I'm insulting you now because you actually are a nasty, indecent bunch of people. And @Mordred is the worst of you. You told me not to be a COMPLETE DICK about my post and my points. Go ahead, be a COMPLETE CUNT about me and ban me.

OMG, you're all so kind to me. Thank You!

@Mordred ... Conformal time η=∫dη=∫dt/a(t) includes the whole expansion history, because the scale factor function of time a(t) IS the expansion history. You're worse than a liar at this point. Much worse. @Mordred EVERYTHING you wrote indicated that COSMIC or COSMOLOGICAL time IS THE CONFORMAL TIME. Try to deny it, please, make my day. You know exactly what I was banned for. https://www.scienceforums.net/topic/140238-cancel-culture-in-major-astronomy-communities/ You shouldn't defend a liar, you know? Just a thought.

@swansont @Phi for All Can you see now what I'm dealing with on your forum regarding the fact that @Mordred is Resident Expert, Super Nerd and Glorious Leader?

@Mordred ... I asked you whether 13.8 billion years is the age of the universe in the conformal time, and you confirmed. I asked you whether you don't have a problem with calling 13.8 billion years a conformal time, and you denied. And you insinuated yourself earlier multiple times, that it's the conformal time, so now your evasiveness reached its peak and you're practically a liar at this point. More than that. At the very end you asked me if I'm sure that you're wrong. Yes @Mordred you were wrong, and now you're trying to act like you weren't. That's very, very low, and I totally disrespect you for it.

@Mordred yes, I am. Read the underlined text and text in the red frame. https://www.scienceforums.net/topic/140204-physical-conformal-age-of-the-universe/page/5/#findComment-1305391 And find the same text in the wikipedia - there is a link.
