Big Bounce confirmed - maybe?

But if the 'Big Bounce' theory is correct then why would the universe be expanding at an accelerating rate?

This paper is pretty old. I've just read through the comments and discussion under the link and have to say this stuck out the most

""The Hindus knew what Penrose claims, 5000 years ago. Called the Breath of Brahma, they knew the universe was an 'eternally expanding-contracting' (sphere) volume. The time of expansion occurs over 4 eras, aeons, or as the Hindi say, 'Yugas', which last billions of years each.

So Roger, read up on the Hindu beliefs in the Vedas and Upanishads. But to confirm their belief scientifically and mathematically is great! We have to get around our linear thinking and understand that the universe is, was, and always will be, a periodic entity whose primary purpose is to express infinity. Every possible permutation of energy must be expressed, and since that is an infinite proposition, we'll be undergoing the process forever, just as we have eternal nothingness to balance out 'yin and yang' or "heaven & hell" - which isn't news, folks!

As JFK said best, "I am a donut" - the torus (perhaps like Haramein's double torus) is forever oscillating. How cool is that?!""

Yeah, the DM article was recent so I added in the other as well.

If there is evidence for a big crunch then it goes against the evidence that the universe is expanding at an accelerating rate.

I thought we don't know why the universe is accelerating though. What if it's accelerating because of something that may run out in the future?

calculated mass of the universe, speed it's expanding is faster than the determined escape velocity therefore it shouldn't slow down and collapse under it's own gravity.

Is how I believe they determined it

Dark matter is actually made of invisible bungee cords - when they reach their limit, they'll spring back and cause the universe to collapse again (c:

technically, JFK's Berliner was a jammy doughnut, not a torus
