Re: one question about objective reality you'd want answered

Here's my question...

How much matter can be squeezed into a black hole before it explodes?

Time travel would mess with causality. So what? Doesn't mean it is no possible, it merely means that our theory wouldn't be able to deal with it so we'd have to throw it out and get a better one. In science you do not rule out observations just because your current theory says they cannot exist.
At some point there is a definitive finish line. Because otherwise the universe would be chaotic and fall apart. And there are still no observations of sound in space, FTL travel/communication or Superman, etc... .

Quantum entanglement, at least information can already travel faster than light. You build a quantum computer and you might be able to calculate stuff which is physically impossible with a normal computer. Quantum mechanics implies all kind of crazy stuff so I doubt that we have, as you claim, learned most of what there is to learn about how the world ticks in the last 100 years.
FTL radio communication will still never ever be possible. And whatever things QM will bring, c is a constant that will never ever change. If there's such a thing as communication using quantum entanglement, then that might be going to work, but it won't be radio communication. If there's such a thing as Alcubierre drive, it might also work, but it won't be a conventional Newtonian drive. And even then there will be things that are just impossible because they don't work within the limits set by our own universe! You won't be able to do wizardry and create fantasy with Quantum Mechanics. That's just nonsense.

If I wanted to ask about the Ultimate Truths of the universe I probably wouldn't frame the question around anthropomorphic megabeings. Our ideas of god may not be coherent or meaningful. Better to just ask, "so how does reality really work"?

Ah.

Now here's the thing.

The universe is chaotic. What do you think people like Hawking have been rabbiting on about for years?

The thing is...


... it doesn't fall apart...

... it falls together. Always balancing on the edge of catastrophe and amazement.

..

..

..

Have you not been around TNZ long enough to know this?

Aren't there some theories that this could actually happen in the far future, matter would start to fall apart?

Re: one question about objective reality you'd want answered

Another question I thought of:

Do all animals have thoughts and feelings? Are they sentient? If only some are, which ones?

I've often been curious about the internal mental states of various animals as well, such as cats and dogs.

Internal mental state of cats:

"Wait on me."

Internal mental state of dogs:

"Why yes, I'll chase that stick that you threw 8,000,000 times already. I will also eat my own shit and drool on everything and hump your legs. Any questions?"

Re: one question about objective reality you'd want answered

I just want to know what my cat is sensing when he stands in the hallway and howls at nothing.

I'd love to be a fly for five minutes, or a dog, or a shark, or a blue whale, or a hummingbird. I want to figure out how complex a brain has to be before there's the tiniest spark of awareness.

More complex than Snooki's brain.

Re: one question about objective reality you'd want answered

My question will be "How will Humanity end"?

In 5 billion years when the Sun dies, will Humankind still be around in whatever form - spread out across the stars - or will we be forever confined to the Sol system and when it goes, our descendants will go with it?

One question I've had is why is the sky blue. I can understand clouds being dark and gray, but why blue for the Sky?

Scientists have figured that out.

That was a very interesting and sensible read. Also liked how they tied the red sunset into it.
