If the robots take over, what would our biosignatures look like? is a galaxy's rotation tied to its black hole? what would happen to the Universe if dark matter disappeared? And in Q&A+, which scifi universe would I like to live in?
00:00 Intro
00:25 [@AriasThirdOfHisName] What will be left of us if robots take over?
04:52 [@Frosty.Winnipeg] Is the rotation of a galaxy tied in any way to the rotation of its black hole?
06:09 [@EdSceptic-y2e] What would happen if all the dark matter dissappeared?
11:19 [@christiandesalliers4663] Why does material must shead it's angular momentum before falling into a black hole?
14:58 [@BigC799] What three questions would I ask the Universe?
15:49 [@kimbarron4239] Which fictional universe would I like to live in?
17:40 Outro

I'm a little confused because I thought if you fire your rocket engines in the direction of your orbit, you will end up going higher and slower. If you fire against your path don't you end up going faster, lower and re-entering? Am I wrong here? Can someone please help me?
You are entirely correct Stephen. The extra kinetic energy comes from the loss of gravitational energy.
What's the best way to submit a question to Q&A?
You just did 😊
AI: Will it make something or will they make something? What happens when you send AI Cores more than a few light-second lag? Fracture? Civil War? Would they first turn Earth into nothing but electrical generators and data centers? Ni bios here necessary. Snowball Earth might be ideal.
For me : 1- culture 2- Star Trek The stories in the Culture books can be brutal. But 99.9999% of the culture's humanity live their best life.
Indeed some of the Culture can be brutal. Not sure which book now but I remember a civilisation practising essentially cannibalism, of which our protagonist barely escaped.
Would robotic, AI or computer-based entities 'Want' to keep 'living'? I'm serious - lifeforms of a biological form have a deep pre-programmed desire to reproduce. Do our electronic emissaries have the same 'impulse' and if so, why would that be so? What possible need would digital or synthetic life have for 'enduring'? It presumably would not be for familial reasons, would not derive from any evolutionary impulse, would not be based on 'feelings', lest our creations become vastly more similar to 'meat life'. Just questioning some or the deep assumptions underpinning all this, which seem far more HUMAN reasons than synthetic.
Even if they do 'want' to keep 'living', they're effectively immortal? What's the motivation to expand exponentially using more and more energy? One star every few billion years would be sustainable?
I was expecting Fraser to choose Culture.
Keep the faith buddy! I'm pleased Universe today is safe,This is the way forward! For the many not the few!
Thank you for keeping us updated and thank you for increasing the volume of interviews.
I'm really glad the move away from ads has worked out Fraser, well done and congratulations.
