I'd say yes, though I understand little of astronomy. I essentially believe what I'm told 의해 astronomers and physicists on the issue, and there's widespread agreement that the universe is still expanding.

I see. Fair enough. I know a little of astronomy myself and yes, I do believe that it is still expanding. Whether it is, 또는 not, is another question... I don't honestly know, but it is actually a rather difficult to answer, because there are so many factors to take into consideration... Plus, the Universe is absolutely massive.

Actually, I will rephrase... I believe that the Universe has always inhabited the same amount of 우주 that it does now... I feel that it could have potentially always existed.

Heh, I believe we've had this conversation before.

Oh, I know, I was making sure that I rephrased myself... I don't want to sound TOO sure on something I'm not that sure about... Haha

I believe the Universe is expanding, I do not believe it is expanding 'outwards' though. The Universe is everything. All 우주 and time, everything that exists. So there is no 'outwards', because there is no 'outside' to everything, to the universe, unless 당신 believe in multiple universes 또는 something like that. Which some people do.
The Universe I do believe is expanding though. As do many Astronomers (which I plan to become one 일 xD)
But scientists do seem to believe that the universe is growing. And because we see it becoming bigger so rapidly that led to the idea that at one point it was much much smaller, which as 당신 probably know led to the Big Bang Theory. We calculated this rate that the universe seems to be expanding at and retraced it to when the universe was supposedly the size of only a proton about 13.8 billion years ago.

Why the universe is expanding, we are not sure. There's many different theories. Some of these theories include, our universe is somehow getting pulled into another universe with a stronger gravitational pull. 또는 religious views which some state, as humans become 더 많이 advanced, God is giving us 더 많이 우주 to study and explore.

But not only is the universe expanding, but science also shows that that expansion rate is accelerating. The most accepted explanation for this is link Research shows that dark energy accounts for about 74% of the entire universe. Before we knew about dark energy, scientists believed that gravity should be causing the universe's expansion speed to slow down. But with dark energy science suggests that dark energy outperforms gravity's pull and is making the universe expand faster and faster.

Plenty of Astronomers believe that the Universe itself is like a balloon. If 당신 take a marker and make a bunch of dots onto the balloon the dots will be very close if the balloon is not inflated. But when blown up the dots spread far apart from each other. This is what seems to be happening as the universe expands. All celestial bodies, stars, planets, galaxies ect. Seem to all slowly be moving away farther and farther from each other. This act is known as link.

But then again we're not even exactly sure what dark energy is. Nor are we 100% sure of the Big Bang 또는 other accepted theories. So the field is open to all sorts of explanations ~

I have a 질문 for you... Where did 당신 come 의해 this information? Plus, I have another... How are we sure that the Universe really is expanding? Could it simply not be an endless void - something that neither grows, nor shrinks, just everything... So incomprehensible that the human mind could not even begin to understand it? I have a thought... What if the Big Bang was actually the Hypernova of a semi-massive star, one large enough to put off enough energy to create enough energy to form a galaxy, and create enough debris to eventually form planets... What if the Universe has always existed... That time and 우주 have always inhabited the same amount of 우주 that it does now...?

Well, I acquired this information through various books, websites, shows, and then some from my uncle who happens to be a professional Astronomer himself. We know the universe is expanding, well maybe not the entire universe (we aren't quite sure if there is something beyond the visible universe) but we know the observable universe is expanding because of redshifts. Which are wavelengths of light is stretched, so the light is seen as 'shifted' towards the red part of the spectrum. And with this we can measure how far about celestial objects are. And we see that they are all spreading apart moving farther and farther away. Which means that at least the observable universe is expanding. It could be possible that the visible universe is just filling in all the 우주 of the whole entire universe. And that the actual universe itself may not be expanding.

Wow, just... Wow. I honestly never thought of it that way. That is truly amazing. Are 당신 sure 당신 aren't a genius in disguise, 또는 something? Anyway, I understand what 당신 mean... If there is an infinite amount of small, which applies to everything (take micrometers and nanometers for instance) then that means that there would certainly be the potential for even much larger things to exist. What if the Universe we think we know is actually just a micro-Universe making up a tiny fragment of an even larger macro-Universe? What if black holes could infinitely expand and contract until they cover an area larger than some galaxies? The possibilities are, 당신 guessed it, infinite. Honestly, I'm glad there's someone out there that thinks of crazy shizz like I do... I don't feel so alone anymore. Oh, and for the record, to me your idea doesn't sound crazy in any way - In fact, I think it is brilliant.
