How dumb, because you are sucking the resources and mapower out of everyone for your $1bln yacht, and uncomfortable lifestyle and that leaves the rest of the world dragging in the mud, while you, your boat, and the 6 billion doomed people are simply preoccupied while you wait for armageddon.
We are going to be extinct within the next 50-100 years.
Either an asteroid, a comet, our own planet, ourselves, or SOMETHING will completely wipe out the life on earth, it happened many times before, and i'm sure wer'e due for another mass-extinction soon.
We seriously need to knuckle down, start a revolution against the economic society, and build a new, [b]cosmic[/b] society.
Why work for money? You can work for the benefit of yourself and everyone around you by doing something COOL and building space-stations, mining asteroids etc. (Ok, maybe some form of money is required around the place to keep people enthusiastic, but the whole arena of share-markets, investing, business, and other economic bullshit is just keeping us down.)
Hell, if everyone got together with strong minds, we could do great things.
We would need to FIND our minds, then get together and build a series of NFP (Not For Profit. That means the only thing we get out of them is the resources they produce, and we keep the resources, not sell them.) foundries, farms and power plants to start us off. Once we have our free resources, we can start inventing the technology required to get us INTO space.
THEN we can think of mining the local asteroids, and building shipyards, and eventually spaceships capable of interstellar travel, but the ships would need to be huge, because FTL is not possible (Unless someone invents a primary inversion drive, which accellerates [i]around[/i] light-speed, not through it.), and a civilization would need to exist on these generation ships, who would colonize new worlds, after travelling for many years through open space...
sounds dumb? well you are still stuck in your single-mindedness aren't you?[/QUOTE]
wow bro
you're the first one ever to have this idea
I want to believe.

Okay Karl.
[QUOTE=JohnnyMo1;28516709]Firstly, you can't travel at light speed to begin with. Secondly, velocities don't add under relativity like they do in classical physics. Under the way velocities add relativistically, you still have a speed limit at the speed of light.[/QUOTE]
Sure, unless you take into account the research being done on attaching individual particles to light particles that are already traveling at the speed of light. You can't accelerate to the speed of light, but some researchers believe that you can hitch a ride on things that are already traveling at that speed.
[QUOTE=ThePuska;28503780]I have no idea how you could reproduce or transfer a consciousness. Your consciousness is bound to your body, not to some soul entity that could jump from your body to a computer. If there was a way to read people's minds, record all their experiences onto a computer and make the computer think as you do, it'd essentially be you. It would have all reason to believe it's you, because it'd share your experiences. But unless the process involved dissecting your brain or something, your physical body would still continue being alive and thinking. There would be two people with your experiences now. Two people knowing for a fact that they're you.
Either you could commit voluntary suicide and let the computer-you keep living, or you could continue living as two people. Your consciousness doesn't jump.[/QUOTE]
Can we put our brains inside machines though?
I hope that works..

I'm pretty certain you just made that up unless you find me a reference because:
A) You can't "attach" things to light. Photons are massless particles. There's essentially nothing there. It's just a quantum of energy propagating through space.
B) Just because you use light to accelerate something doesn't mean you can accelerate it to the speed of light. Light has finite momentum and you'd need infinite to get a non-massless object up to c.

Photons are not massless. Their mass is almost zero, but not quite. If they had no mass, a solar sail could not function.

I don't understand how a photon can exert physical force and possess momentum if its mass is truly zero. Can anyone help me understand that?

I don't know how you get to this, but the momentum of massless objects are calulated by using this forumla.
p = hf/c
h is planck's constant

They have energy but no mass.
[QUOTE=Kingy_why;28528973]They have energy but no mass.[/QUOTE]
That is absolutely crazy. I guess it makes sense, though.
[QUOTE=GeneralSpecific;28528710]I am now marginally less confused.[/QUOTE]
Ok this might not be done correctly as I haven't studied this far yet, but at least you'll understand.
Energy of a proton is calculated trough E=hf
h is planck's constant and f is the frequency of the light.
E=mc^2 -> m = E/(c^2)
as E=hf then
m = hf/(c^2)
p = mv This is the momentum of objects with mass m(kg) and velocity v(m/s).
so for light v = c
p =mv = hfc/(c^2) = hf/c
which gives
p = hf/c
Woho!
"Either we'll blow ourselves up or we'll become too self involved", is an extremely black and white way of looking at things.
[QUOTE=GeneralSpecific;28528496]I don't understand how a photon can exert physical force and possess momentum if its mass is truly zero. Can anyone help me understand that?[/QUOTE]
p = γmv. You can think of it like the mass is 0 and gamma is infinite so by the power of magnets they produce a finite number but you can't determine what it is that way so it's easier to just say they exert a radiation pressure.
If there was a "science party" they'd certainly get my vote.
People need to understand that science and technology are the way forward, out of this pothole of idiocy.
I always love Eudoxia's threads. Keep up the good work, old friend, I hope to see many more.

also i can't believe how many people in this thread are saying transferring consciousness isn't possible. you must be fucking daft to say that when no one has even attempted it before, no less be actually serious about trying to accomplish it to my knowledge.
basically, you don't know fucking shit and neither do it so don't act like you do when it's just a fucking thought experiment
[QUOTE=Kai-ryuu;28502826]it saddens me to realize that the day FTL even becomes a blip on the reality radar I'll be six feet under :smith:[/QUOTE]

No, I didn't make it up, I read an article about it ages ago, and it was in a documentary with that one really famous asian scientist guy on the science channel. Always forget his name. I'll see if I can find a reference.
