The whole point is that evidence never comes in all at once, yet science will follow the evidence wherever it may lead. Rather than sticking stubbornly to an old belief in the face of new evidence, science evolves, and our understanding gets enriched in the process.

The big bang theory has passed a number of tests and took decades to become the prominent theory. Support for big bang and the preceding steady state theory was pretty evenly split until a a feature predicted by the big bang theory was discovered. The big bang theory predicted there should be a type of echo of the expansion coming from every direction in the sky. Big bang theory was first proposed in the 1920's but the predicted feature wasn't found until the 1960's. The was the cosmic microwave background or CMB. When it was discovered big bang theory became dominant and has remained so ever since. Which isn't to say that wont change. But a cyclic universe to me isn't a great deal different as such. Pretty much the same thing except it's endlessly repeating. Quote Link to comment Share on other sites More sharing options...

A Big Bounce idea, which this seems to be, has been around for ages. Indeed, it's been my preferred theory for years. Indeed, the idea has been around since at least the mid 20th century. Recent evidence suggests the expansion of the universe is accelerating with the math ruling out a rebound. But in saying that I don't know if an idea proposed by physicist Lawrence Krauss may still suggest a series of universes. He wrote a book called 'A Universe from Nothing: Why There Is Something Rather than Nothing', in which he describes how the universe may have begun from absolutely nothing. Literally nothing, not even space existed. Now presume his hypothesis were correct. Would that mean even if the universe spreads out, ultimately fizzles out till there is absolutely nothing, not even particles left, that it could begin again, from absolutely nothing?

I just mean that out of all the various things you hear whenever you're flicking through the telly and stumble on some Prof Brian Cox programme or Discovery/Nat Geo show, the bounce one made most sense to me. I'm most definitely not suggesting I actually have any real knowledge about this. Just shit gleaned from reading articles and watching telly.

JFK-1 Posted February 18, 2021 Share Posted February 18, 2021 (edited) Going to be a landing by a NASA rover on Mars later tonight. Or, fingers crossed, maybe I should say an attempted landing. The major mission of this rover, the rover is called 'Perseverance', is to search for signs of past life on Mars. And you can watch live as the rover goes through what the NASA scientists call "7 minutes of terror". The 7 minutes is the approximate time it takes from first touching the edge of the Mars atmosphere to touchdown on the surface. The Mars landing will start streaming from 7.15pm UK time on Thursday 18 February. Edited February 18, 2021 by JFK-1 Quote Link to comment Share on other sites More sharing options...
