would have liked to thumb this up, but my ADD(led) mind won't go that far

It also indicates that logically, proof is a weaker concept than true; such a concept is unsettling for scientists because it means there will always be things that, despite being true, cannot be proven to be true. - in #1 Godels incompleteness theorems

Wonder what God thinks of that.

Strange indeed, what does god think of this shit?

Mordic, faster than light travel is impossible in our universe simply due to the mass energy equivalence, my memory is rusty, but it works something like, due to the formula being E=mc^2, with C being the speed of light, as you increase the speed of an object, it increases its energy, this also increases its mass. Because of the relationship between these two and the speed of light, as an object approaches the speed of light the energy required to advance it further becomes higher, due to the increase in mass, until you need an infinite amount of energy to push it past the light speed barrier. There's no law stating it's illegal in the universe, it's just physically impossible through conventional means.

Thumbed this down as soon as i saw the title expecting to see some bullshit about perpetual motion machines or aliens or something but these are all legitimate observed phenomenon in the universe and they're all explained really well. I'm surprised.

I realized that what I had been thinking about for a while - without knowing until now what it was - was the antimatter retro-causality especially related to phenomenon of vacuum fluctuations.

Feynman FTW, I say.

It's nice to read an article summarizing this topic. It seems many of the resources are typically focused on just one theory so it's a bit daunting to find a nice synopsis.

From the page: It is not strictly science, but rather a very interesting set of mathematical theorems about logic and the philosophy that is definitely relevant to science as a whole. Proven in 1931 by Kurt Godel, these theories say that with any given set of logical rules, except for the most simple, there will always be statements that are undecidable, meaning that they cannot be proven or disproven due to the inevitable self-referential nature of any logical systems that is even remotely complicated. This is thought to indicate that there is no grand mathematical system capable of proving or disproving all statements. An undecidable statement can be thought of as a mathematical form of a statement like "I always lie." Because the statement makes reference to the language being used to describe it, it cannot be known whether the statement is true or not. However, an undecidable statement does not need to be explicitly self-referential to be undecidable. The main conclusion of Godel's incompleteness theorems is that all logical systems will have statements that cannot be proven or disproven; therefore, all logical systems must be "incomplete."

The philosophical implications of these theorems are widespread. The set suggests that in physics, a "theory of everything" may be impossible, as no set of rules can explain every possible event or outcome. It also indicates that logically, "proof" is a weaker concept than "true"; such a concept is unsettling for scientists because it means there will always be things that, despite being true, cannot be proven to be true. Since this set of theorems also applies to computers, it also means that our own minds are incomplete and that there are some ideas we can never know, including whether our own minds are consistent (i.e. our reasoning contains no incorrect contradictions). This is because the second of Godel's incompleteness theorems states that no consistent system can prove its own consistency, meaning that no sane mind can prove its own sanity. Also, since that same law states that any system able to prove its consistency to itself must be inconsistent, any mind that believes it can prove its own sanity is, therefore, insane.

A lot of mind-blowing theories about reality put into a handy list that most educated laypeople can read. Fascinating stuff.
