Hope you are thinking about more advanced machines than we currently have, I would hate to have my mind entrusted to my henry hoover
Or something running Windows 8.
The universe really did come from nothing

Incidentally, I am waiting at the moment for the library to get me a copy of Ian M Bank's first novel of his sci-fi series iirc "Consider Phlebas" I think you recommended it to me. Looking forward to getting it.Very true. However, there's nothing stopping us (ok, so the details need working out but) copying our minds into machines that have no qualms about waiting 1,000 years to get somewhere

so if i were to get out of bed to make coffee i would accelerate faster than the speed of light?

On the issue of Sci-fi, I wonder if things like warp drive, hyperspace, teleporting, babelfish, intergalactic travel, cloning and the like, or perhaps if some of them, may come to pass?
I suppose it could be interesting, I don't know how long sci-fi has been around, to go back 100 years and see what future fantasy literature there was at that time, and how much of that has come true today?

You would approach, but never reach it, whilst becoming infinitely massive. Please don't, it would make a mess.

"hyperspace" travel really would require rewriting the book of physics, and the number of empty pages is getting smaller all the time. Warp drive is a theoretical possiblity, however: https://en.wikipedia.org/wiki/Alcubierre_drive
Intergalactic travel would just take a *really* long time
I reckon I'll see a human clone in my lifetime.
Teleportation is impossible. Heisenberg says we can't know where every particle is, so how can we copy it?

And yet I believe there is so much space between the particles in every atom of our bodies that if this space was reduced to nothing, we could fit the entire population of China inside a single matchbox.
eta: of course the mass of the box would be massive

That's not what he said. We can't know both its speed and its position, but we could know either one in its own.

Ok, so to succesfully copy something, we have to freeze it to absolute zero first

No doubt about that at all in my mind.
The big one I'm hoping for is that I'll get a chance to go into space in my lifetime. That projects like the Vigin Galactic thingy are just the start of a huge growth industry, a bit like air travel has been over the last 50 years or so.

It's been done with a photon. Why couldn't two photons be copied? Keep scaling up. Admittedly it's not easy, but it's not impossible.

I hope you are very young !!
Most of the current space things from entrepreneurs are just buzz up into it for a moment and then return down to earth.
I expect any interplanetary travel, the moon or mars in my lifetime perhaps, will still involve elite astronauts drawn from air forces with strong science backgrounds. Unless this idea of a married couple going to mars comes to anything.

Elon Musk's genuine ambition and entire reason for starting SpaceX is to settle Mars with thousands of colonists. If he's even halfway successful, then the rest of the industry will be dragged along and it's possible that orbital space travel will be in the reach of "normal" people (ie. relatively wealthy westerners)

Yep. I'd be happy with just doing a couple of laps of the earth, anything more would just be a bonus really.

I expect space exploration to be like it was when privately funded square riggers set out to discover the new world map the oceans and discover the potato
There will be multiple long term missions financed by rich entrepreneurial families seeking out planets heavy in valuable resources, diamonds, helium-3, gold, etc and the space ships may only return a generation after departing, the profits being made by the children of the initial investors.

Please excuse my terrible use of phrases I was merely just using the most basic of examples to relate it to something that could be visualised. I'm no scientist, I don't know the inns and outs of everything but I hoped you all watched that lecture video? It explains things perfectly.
Yes the universe is expanding faster than the speed of light but light will always travel at the same speed and so 100billion years in the future when you look up at the sky with a telescope you'll see just your own galaxy and that's it, apart from that there is just pure blackness.
With regards to teleportation it is possible because it's been done with single particals, although the partical doesn't move anywhere, it's destroyed in it's place and created in another but it is the same partical. If you did that with a human, you'd look exactly the same, have the exact same thoughts and memories, the same voice ect but is it really you? The answer is no. The original you that stands in the machine is destroyed and a new you is created.
Things like this most likely will never happen due to ethical reasons and secondly if the soul does exist, we still don't know but if it does, does that also go with you into your new body or not?
To be honest the best thing is simply to take our brains out, put them in an artifical body and long live and prosper

It is going to aeons till there is an artificial body as wonderful and perfect as my self repairing, growing, learning, expressive, flexible, strong, versatile and adaptable body.
Yes background radiation is microwave radiation that remains from the big bang.
Perhaps. Why is it called universal background radiation? Or cosmic?

forward communism, forward gerbils!
I was getting at a different point. Its more of a question really that I am interested in your or anyone's answer to.
So the universal background radiation (so called because it appears to be uniform across the universe) is meant to be a constant?
How is this possible in an expanding universe? More specifically... if all matter is moving away from all other matter... then why is the electromagnetic radiation not more concentrated in certain areas than others? Logically it should become less concentrated as you approach the edges of the universe.
I don't get it. And I don't see how this supports a but bang theory.
Things are not moving away from each other, space-time is expanding which is then pulling everything away from each other, you know if you draw 3 dots on a balloon and as it inflates the dots get further away without having moved at all? Basically like that.
That backgroud radiation is like the echo of the big bang and eventually, in billions of years time the radiation will get weaker and weaker until it can no longer be detected.
