maroonlegions Posted January 30, 2018 Share Posted January 30, 2018 (edited) Even more mind blowing possibilities or at least appears so in the realm of the "early days" scenario. A study has revealed the possibility of the holographic universe thesis. Pure barking mad but still this study comes from credible scientific sources. Is this universe, possibly one of others, more stranger than ever as more data reveals it to be?? A UK, Canadian and Italian study has provided what researchers believe is the first observational evidence that our universe could be a vast and complex hologram. "Theoretical physicists and astrophysicists, investigating irregularities in the cosmic microwave background (the 'afterglow' of the Big Bang), have found there is substantial evidence supporting a holographic explanation of the universe—in fact, as much as there is for the traditional explanation of these irregularities using the theory of cosmic inflation. The researchers, from the University of Southampton (UK), University of Waterloo (Canada), Perimeter Institute (Canada), INFN, Lecce (Italy) and the University of Salento (Italy), have published findings in the journal Physical Review Letters". A holographic universe, an idea first suggested in the 1990s, is one where all the information that makes up our 3-D 'reality' (plus time) is contained in a 2-D surface on its boundaries.

He attempts to explain what we've been talking about. Well, I'm not in a hurry, which maybe explains why most of it is 'way over my head. There's a couple of good podcasts with Neil on the Joe Rogan show. He convinces Joe about the moon landings etc... Joe was a non believer before it.

For example, Albert Einstein rarely set foot in a laboratory. He did his most famous work, his theory of General Relativity, with nothing more than a pencil and paper. That wasn't pish then, and it isn't pish now. What he proposed consisted purely of mathematics, but countless observations since then have confirmed the accuracy of what he calculated. Similarly, when Copernicus proposed the heliocentric solar system, it was all mathematics. You don't have to "actually go" somewhere to make him right. I'm not a sceptical person. I actually love all this cosmos stuff. But come on , some of it is complete fantasy land. Just like God, but hey heaven could be in one of these multiverse thingies.

Some of the things you read about in astronomy are fantasy, but not much. The multiverse notion is one of those. It's currently more science fiction than science. But astronomy is continually making new discoveries, which generates a lot of debate and numerous hypotheses. We still have a lot to learn in this area, but we need to follow the scientific method when analysing the data. Getting side-tracked into wild speculation doesn't achieve anything, except maybe generate sensationalist headlines. Quote Link to comment Share on other sites More sharing options...

Because the sun is far more massive it is assumed that in relative terms it is stationary in space while the earth moves around it.

I wish scientists would say "honestly, we don't know, here's a guess " Any astronomer worth his salt should be saying that everyday! We as individuals, and we as a species, shouldn't be too hard on ourselves over our lack of understanding in this field. Homo sapiens has been around for hundreds of thousands of years, but we've been seriously studying the cosmos for only about four centuries. To say that we have a lot to learn is an understatement. All we can do is keep enquiring. Particle accelerators like CERN will help us learn more about the extremely small, and bigger more sophisticated telescopes will help us learn more about the very large. But there is a possibility that we'll never figure it all out. It could be that our brains are wired in such a way that we'll never understand the cosmos. Our bodies and brains evolved to help us survive in the plains of Africa. Maybe expecting humans to understand the universe is like expecting a West Highland Terrier to understand Euclidean geometry.

Bordeaux 03 Posted January 31, 2018 Share Posted January 31, 2018 Until recently I had no idea that the planets don't orbit the Sun but they orbit the barycenter of the Solar System. This is the point in which the mass of objects balance out, but because most of the planets are so small compared to the Sun, this point is actually inside the Sun. Although, this isn't the case for Jupiter, as it is so massive the barycenter sits outside the Sun and technically means it doesn't orbit the Sun.

The moon orbits the earth. Nope. Any two masses in a gravitational lock actually orbit each other. If both had the same mass they would orbit each other perfectly and you would not be able to say which orbits which. For example there are many identified suns in the galaxy which are locked in orbit with each other "twin stars". From the perspective here on earth you cannot say which one is stationary and which "orbits". If the mass of one body exceeds the other the orbital centre moves but the principle remains - they both orbit round an orbital "centre". As the suns mass is extremely large compared to earth it looks like the earth is orbiting the sun, but the original gravitational principle remains. Have a Gin and it will become clear.

Justin Z Posted January 31, 2018 Share Posted January 31, 2018 True but to say they "orbit each other" doesn't work. They create a gravitational system orbiting around a centre of mass, the barycentre. In the case of the Sun and all the planets save Jupiter, the barycentre is inside the sun. So to say the Sun "orbits" the Earth or Jupiter really isn't accurate. At best, the Sun wobbles, or orbits a point just outside itself on the absolute edge case.

They are of course both orbitting a centre as all planetary bodies do. But as I posted earlier, its about where you choose your reference point. If you choose your reference point to be on earth then the sun is actually orbiting you every year. The "wobble" in the sun you quote isn't a wobble, it is an orbital locus - small, but still an orbital path. Same story with the earth and moon. The notion that the earth somehow doesn't move and the moon simply orbits around it is equally wrong. Quote Link to comment Share on other sites More sharing options...

Nope but thanks for trying. The answer is a bit complicated so bear with me. The moon is tidally-locked to earth, in other words you always see the same side of the moon viewed from earth no matter when - it doesn't spin on its axis relative to earth, or to be more exact it spins at exactly the same rate as it orbits the earth - 28 days to be exact-ish. No humans except the Apollo astronauts have ever seen the far side of the moon. Anyway, this worked in the Apollo missions favour, as the six landing sites had to be chosen on the earth-side in order to maintain permanent radio contact with Houston. Now given this tidal locking, the earth, as viewed from the moon, is in the same place in the sky, every day - it never moves. It doesn't rise or set - it is there all the time in the same place, and as the landing sites were all chosen on the earth-facing side, the earth was always almost directly above the Astros heads, so never appears in photos. In fact I think there are a couple of photos - one of Aldrin I think but taken with the camera on the ground looking upwards to get the Astro and the Earth in the same shot.

Aye, I'm sure it did. It helps to keep the language used and context in view when gaining an understanding of the text. Biblical passages that cite sunrise and sunset do not teach that the sun orbits the earth every 24hrs. By this reasoning, nearly all astronomers and astronomical periodicals are geocentric, because ‘sunrise’ and ‘sunset’ is the language that is used to describe the interaction. As well as the bible bringing forward the idea of an expanding universe, one that has been stretched out. It also tells us that the earth floats in space, unsupported by any object.

Biblical passages that cite sunrise and sunset do not teach that the sun orbits the earth every 24hrs. By this reasoning, nearly all astronomers and astronomical periodicals are geocentric, because ‘sunrise’ and ‘sunset’ is the language that is used to describe the interaction. As well as the bible bringing forward the idea of an expanding universe, one that has been stretched out. It also tells us that the earth floats in space, unsupported by any object. In fact there are a number of passages that touch upon the topic of astronomy etc. I am always pleased to reply to your posts. You are flying affy fast and loose with your interpretations there, buddy. Does the Bible really describe expansion of the universe? https://creation.com/bible-cosmological-expansion Quote Link to comment Share on other sites More sharing options...

It's more like the way you might spread out a blanket or curtains. They obviously aren't getting physically bigger when you do that. Nice display of probably the most glaring symptom of fundamentalism on show for all of us. Not sure it's worth getting noised up over, Smithee.
