"Can someone explain this problem?
1. The speed of light is suppose to be a constant at 299,792,458 m/s.
2. The size of the universe is suppose to be billions of light years across.
3. The universe is suppose to have expanded to close to its present size during the 'Big Bang' in a fraction of a second.
"
The size of the visible universe is a little bigger than the Hubble volume. But, and this is usually, almost invariably, ignored, the whole universe by the popular model has a radius 25 billion times larger than the Hubble radius. The rest is not visible because it is moving away from us faster than the speed of light and always was after the inflation phase of the Big Bang was underway.
BTW, the speed of light is not the sacred limit of all possible speed in the Theory of Relativity either, even though popular legend says it is.
The entity that "exploded" in the Big Bang was a singularity prior to the Big Bang, and conventional physics don't apply to singularities (or so I've heard).
The Big Bang Theory: First there was nothing, then it blew up.
Is C the limit for things with mass? Isn't there something called a nutrino that has almost no mass and besides being able to pass through the earth, can also travel faster than C?
LOL!
You were gonna go fishin', wernt ya?
That's not it. Relativity could have been developed with the speed of sound as an example, but the author chose electromagnetism because it was more interesting to him. It's just an example that took care of some inconsistencies involving propagation of light, which was the hot issue of the day.
And it seems like a lot of the current theories, e.g. dark matter, are being cobbled together out of nothing, with no evidence that it actually exists, to explain something else. I think the need to re-check their math.
Abaal the size of earth made out of steel. Once a year a bird lands on it and sharpens his beak for a few secs. It will take an eternity for the ball to be whittled away to nothing.
PIMF
This would happen just as gas hits an all time high!
And if the universe is bigger and older than previously thought, so what? Why is that newsworthy? Years ago, I was at a planetarium show about the age and fate of our universe. At one point the narrator said that, in about 8 billion years, the sun would burn out and our solar system would perish. Somebody not paying close attention raised a hand to ask about that time frame. The narrator repeated the 8 billion years reference. The questioner breathed a sigh of relief and said, "Whew! I thought you said, 6 billion years!"
"3. The universe is suppose to have expanded to close to its present size during the 'Big Bang' in a fraction of a second."
I think your #3 is wrong. The expansion was fast to begin with, but not to include current galaxies, of which there are billions. And the expansion is ongoing.
From various books, I get the impression that our "universe" is but one of an infinite number of universes, and there are more dimensions of space than the three we are familiar with - some say ten - plus "time".
Of the three, Alceste would definitely be MY first choice...
What if the bird came once every two years? Wouldn't it take twice as long?
The universe has been expanding since the big bang. The wierd thing is, it appears to be accelerating. Dark matter/dark energy may be the cause.
That's what they said about me last time I went to the doctor's office.
So, if I understand you correctly.
The speed of light is a slowly changing variable contrary to how its popularly defined as a constant.
During the Universe's beginnings the speed of light could have been vastly different than presently observed.
Hummm.. Bigger than what?... Older than what?...
