Only as wrong as me having 3 or 4 of his booksIs it wrong that I know who that is?

Yes you would.This is what I was alluding to in the Space X thread (and perhaps it was you who posted the above in a previous thread.
Can't *quite* get my head round it to be fair. Wouldn't you need an almost infinite amount of energy to shift mass at light speed (or near to)?
Exactly. Time slows down for the travelling body compared to the stationary observer. If you stood on an imaginary train platform whilst a train sped past at close to the speed of light, you would notice that all the people on the train were moving in slow motion, their watches ticking more slowly. And if the train was travelling at the speed of light, everyone on the train would be static, frozen. From their perspective on the train they would be carrying on their conversations and everything would be entirely normal, but for them, relative to you on the platform, time has actually stopped.So 'light speed' is our own observation of light traversing the galaxy/universe: it would take us 6 years to watch light travel 6 light years, but the light itself has made that distance instantly...
When you sit and think about this, and think long and hard for a long time, you begin to realise the very profound implications it has for the very nature of our universe and for space and time itself. I've been thinking about it for 45 years. The most profound conclusion is that our concept of "now" is deeply flawed. There is no universal "now" - it is limitation of our human brains and experiences and in fact the past, present and future all exist.

No question that there is life out there somewhere, once the scientists accept that it may not require water and/or oxygen to exist, they will find it ...

It wasn’t even a decent conspiracy theory, just some idiot rambling on.You're not the type to get jiggy with it?
Must admit to a loud belly laugh when, at the end, he said ‘if you liked that then please subscribe to my channel‘. Yes, fuck off you knobhead thought I.
Brilliant - thanks and well explained. That's how I recall it from a previous tread.Yes you would.

And indeed...extraordinarily profound, although what that means to 'us' at this time on earth I'm not quite sure.
I tend to keep an open mind about science as the understanding of it evolves so quickly and we're currently sat in the middle of a huge technological (and bio medical) revolution.
I'm going to start reading more again next year (Brian Greene writes some incredible stuff on the quantum realm) as this year has been more than a little unsettled for me. Hoping for more of a peaceful and less insane year in 2021.
Cheers mate.

I haven't read this yet, but will do.Nice summary of current theories
Nature
If you are interested in this stuff see creating synthetic life but it's not easy.
But I think it's fascinating the work we've been doing on nano-technology and how this will inevitably IMO merge with biology. We can envisage creating incredibly simple nano "machines" by dropping individual atoms into place. However such machines would be useless because at such small scales they would not be able to actually do anything. In order to be useful, you'd need billion of them, and we couldn't possibly make billions of them using that technique. So what you need is some way to make a nano-machine with a set of instructions, with the first instructions being to tell it to replicate itself - 1 becoming 2; 2 becoming 4 etc - and then when billions exist the combined body of nano machines can do something practically useful.
When you think about it, we already have this technology. It's called life. Seems inevitable to me that in our first attempts at making scalable nano-bots we'll borrow some of the techniques used by DNA to encode instructions and to replicate. Why re-invent the wheel when a perfectly good system exists already.
I can easily envisage a situation in maybe 100 years where complex "machines" exist which we effectively grow, just like things grow in life. Synthetic life forms, effectively.

Is the correct answer.With all the trillions of galaxies and planets out there, there's bound to be some form of life, the sad thing is we'll never know as they are billions of light years away.
