Right that the solution accepted to get things over with is ugly?
Yes.

But he has no alternative for anything close to research level mathematics, and moreover it appears he thinks he knows more about the proposals and alternatives than he does.

And don't get started now with the ontological stance on mathematics, this has no right or wrong answer, almost by definition.

No. The oil industry backs the conservatives and pretty much every environmental issue is influenced by our consumption of fossil fuels. It may sway some of the conservatives, but in the end, money talks and the oil industry has plenty of money to throw around

Nope. The conservative right wing hates catholics.

SO, lets get right to it.

In the next ~20 or so years, it is clear that new technologies will emerge and impact the world.

Any ideas towards the next generation?

Currently, my thoughts towards new outcomes of next generation of technology are as follows:

Artificial Intelligence / Machine Learning
Deep Space Exploration
Machine Automation

Thoughts/comments/concerns/rebuttals on the listed topics?
Thoughts on other world changing technologies?

I'm struggling with trying to understand how encryption works the way it does.

I remember an apology where myself and Lucy want to exchange an encrypted message.

We both have private keys and one shared public key.

I use my message and encrypt it using a private key, then use my public key on it and send it to Lucy. She does the same. Then somehow we can decrypt the message??? I don't understand how this works.

At the end of the day, how is it possible that someone monitoring the network can't decrypt the message?

The public key is used to encrypt a message.
Only the private key in that public/private key pair can decrypt messages encrypted with its public key.

You and Lucy would each have your own keypair and keep your private keys secret. You would each use the other's public key to encrypt messages and use your own private key to decrypt messages sent to you.

ITT: God-tier physicists

Pic related. The author of A Universe from Nothing, in the words of also all time greatest scientist Richard Dawkins:

>Even the last remaining trump card of the theologian, ‘Why is there something rather than nothing?,’ shrivels up before your eyes as you read these pages. If ‘On the Origin of Species’ was biology’s deadliest blow to supernaturalism, we may come to see ‘A Universe From Nothing’ as the equivalent from cosmology. The title means exactly what it says. And what it says is devastating.

If nothing can go faster than light, shouldn't we be able to see the entire universe? But we can't, we only see the observable universe, from where light has had time to reach us. But if big bang is correct, everything was "in one place" once, so, that can only mean that the universe has expanded faster than the speed of light.

Is this right?

Yes.
>>
>>7689988

You can't accelerate beyond the speed of light from any given reference. However the universe's expansion is different, it's expanding everywhere at once. Space itself is expanding, which is different from objects moving through space.

Pretty weird.

if at 1e-32s the observ.universe was grapefruit-size that is an expansion speed of 33000c

Is there a point in scientific discovery where the subject matter ceases to be purely empirical?
Is it possible to get to metaphysics through natural physics?
If the big bang truly was the beginning of contingent reality and not some other strange phenomenon governed by physical laws, then wouldn't we have already reached that point?
There are of course unstable quantum vacuum states but they are still physical and thus contingent, and no, they are not a case of "something from nothing."

>Is it possible to get to metaphysics through natural physics?
At that point it'd prolly just amount to the specific metaphors you used to describe natural physics. It'd be valid as long as there was an isomorphism between your metaphors and the natural physics.

Language games and all that... good old wittgenstein
>>
>>7689734

Actually metaphysics is just the branch of philosophy that deals with the nature of reality. So it would encompass physical as well as (hypothetical) non-physical entities.
