Any of you find outer space extremely weird and surreal?

[Dobyzhee]

Space is just an empty vacuum and digital pictures made from NASA.

Nothing to see here.

[Mike D]

Yeah I'm with you Kev. Space is definitely incredibly surreal. Most, if not all of it, blows my little mind to pieces if I really sit there and try to comprehend it.

[-Kev-]

loser. If your trying to make a point then you need to post evidence/facts to back it up. Tf am I gonna look for something to prove your point? Idiot.

You are not very bright are you?

It’s a fact, there is evidence, they are on youtube. But I know this and you don’t. That is on you, not me.

You need your hand held

I am not obligated to show you any evidence for anything. I am 100% right, you are wrong. This is like arguing what does 2+2 equal and you say it is 6 and I say it’s 4 then you ask me to prove that. It’s ******, you can figure it out yourself. It makes you look slow and r3tarded. No need to prove anything to you. If I say unicorns are real, your request for evidence would make sense. But the oceans expedition is real and available to watch.

You refuse to look for the videos because you fear you are wrong and ******? Nice logic moron.

Earth revolves around the Sun: “You are wrong, show me evidence.”

Surprise: the Big **** isn’t the beginning of the universe anymore

Today, the universe as we see it is expanding, rarifying (getting less dense), and cooling. Although it’s tempting to simply extrapolate forward in time, when things will be even larger, less dense, and cooler, the laws of physics allow us to extrapolate backward just as easily. Long ago, the universe was smaller, denser, and hotter. How far back can we take this extrapolation? Mathematically, it’s tempting to go as far as possible: all the way back to infinitesimal sizes and infinite densities and temperatures, or what we know as a singularity. This idea, of a singular beginning to space, time, and the universe, was long known as the Big ****.

But physically, when we looked closely enough, we found that the universe told a different story. Here’s how we know the Big **** isn’t the beginning of the universe anymore.

The modern cosmic picture of our universe’s history begins not with a singularity that we identify with the Big ****, but rather with a period of cosmic inflation that stretches the universe to enormous scales, with uniform properties and spatial flatness. The end of inflation signifies the onset of the hot Big ****. (Credit: Nicole Rager Fuller/National Science Foundation)
Key Takeaways

• The Big **** teaches us that our expanding, cooling universe used to be younger, denser, and hotter in the past.
• However, extrapolating all the way back to a singularity leads to predictions that disagree with what we observe.
• Instead, cosmic inflation preceded and set up the Big ****, changing our cosmic origin story forever.

Since it was hypothesized back in the 1980s, in a variety of ways against the alternative: a universe that began from a singularity. When we stack up the scorecard, we find the following:

1. Inflation reproduces all of the successes of the hot Big ****; there’s nothing that the hot Big **** accounts for that inflation can’t also account for.
2. Inflation offers successful explanations for the puzzles that we simply have to say “initial conditions” for in the hot Big ****.
3. Of the predictions where inflation and a hot Big **** without inflation differ, four of them have been tested to sufficient precision to discriminate between the two. On those four fronts, inflation is 4-for-4, while the hot Big **** is 0-for-4.

But things get really interesting if we look back at our idea of “the beginning.” Whereas a universe with matter and/or radiation — what we get with the hot Big **** — can always be extrapolated back to a singularity, an inflationary universe cannot. Due to its exponential nature, even if you run the clock back an infinite amount of time, space will only approach infinitesimal sizes and infinite temperatures and densities; it will never reach it. This means, rather than inevitably leading to a singularity, inflation absolutely cannot get you to one by itself. The idea that “the universe began from a singularity, and that’s what the Big **** was,” needed to be jettisoned the moment we recognized that an inflationary phase preceded the hot, dense, and matter-and-radiation-filled one we inhabit today.

Yeah. Astronomy is very interesting. Literally 100's of billions of Galaxies. Must be trillions of solar systems like ours. I can't even wrap my head around that figure. I wonder when Humans will begin to augment their bodies to make deep space travel more viable.

When I was 19 I came up with this plan to see space. At this point it's been done a few times over and you can watch one of them on YT. All you need is a big balloon. I'm not scared of hydrogen so that's what I'm wanting to use. I think it's like close to 4 times helium's lifting ability but seems like a lifetime ago I researched this.

Just a big hydrogen balloon with a room attached to it. I'd make an airdeck but it's hardly needed. You wouldn't go to space, you'd be at the very edge of the atmosphere. No air, the gas there is very thin itself and absolutely invisible so you can look out into a direct view of space with 0 impedance. Literally the best place "on earth" you could take a telescope, but I feel like having a window and airdeck to just look at space with, naked eyes, would be awe enough.

Just need a valve to get down. Or you could jump, hang glide, whatever you like really. Plenty of ways to get down from that area because it's not space, there's no weighless, gravity has you still.

Drifting is a simple thing to do, black and white reflecting in a spoon as you take your breakfast looking closer at the craters on the surface of the moon. This space balloon, or maybe sub-space, no that's atom ****, upper atmosphere weather balloon with a box attached has become my Alamo. I will take my breakfast there, In that place where space meets earth, before I die.

Define all that black around the everything?

Dude, I read that same exact article earlier today. I have been lazy about posting it. You beat me to it

The tab is literally still open on my phone from when I was reading it hours ago.

Wouldn't be at all surprised if we see a lot of the same recommendations showing up in our feeds based on stuff you've said so far, man. Them algorithms....

Yep, that is exactly how I saw it as well.

And regarding the article, I still haven’t comment on it because I am still mind blown about it. It was also a lot of info to take in. All I have to say about it is that this is why I love the scientific method. Scientists can be wrong about something, 1,000 times. A thousand theories about something, that can get debunked.

Science is constantly wrong when it is en route to proving something without a shadow of a doubt. Which is what makes science what it is. If you notice, the science community (yes I do mean science in general, not only astronomy or cosmology) is happy to be wrong. Life is a puzzle that spans trillions of light years in distance. The great scientists of Earth, strive to put the pieces together instead of just chalking it up to “god made it.”

People buy puzzles because the challenge is fun. Not because it’s easy. They are fun and interesting to try to put together. The bigger the puzzle, the more challenging it is, and the more a person would enjoy it. Space and life is one seemingly never ending puzzle.

Some people who dismiss science, falsely think that scientists think or claim to know everything and that their theories are definitive answers to something. It’s not. Scientists are having fun when a new theory comes out that it’s better than their theory.
