Most recent revisions of the Alcubierre warp metric requires an energy equivalent to the mass of Jupiter. The human race would have to reach at least Type I status on the Kardashev Scale (currently we are at Type .72) for this shit to work.

>> No.2147432

>>2147417
dude! .72 can round to 1, fuck yea bro we're almost there! Awesome!

>> No.2147439

>>2147432
Yes, but I estimate that it would take at least a century before that happens. Also, the Kardashev scale is an exponential scale so even though .72 sounds high, it is a much wider gap than you think.

Fucking hell, I got excited for a second. Oh well, at least for a second I was actually believing that we would be traveling throughout the stars and I'd be there to see it.

we will most certainly travel to other stars. it's not as impossible as some like to think. even with tech available today. all that's needed is nuke tech.

Wasn't it proven that if you create the bubble you wouldn't be able to escape it ?

>> No.2148264

80 years travel time for regular nuke powered. That's just 2 generations of people that need to be on the boat to get to the nearest star. (5% speed of light)

But for antimatter-matter annihilation (KNOWN to be actually POSSIBLE, just need better tech) we get = 80% speed of light and the time is WAAAAY less. Like 6 years or some such number.

>> No.2148292

I swear to God if that thing get's realised, keeps the name Alcubierre Drive and we travel the galaxy engaging Alcubierre 1 to Alcubierre 10 rather than Warp 1 to Warp 10, I am going to rip fucking Alcubierre's ankles off.

>> No.2148294

try to also bear in mind that the most recent calculations show hawking radiation would destroy any and all object inside the bubble

also a revised calculation shows that a bubble large enough to propel a 200m ship would require
10 billion times the mass of the observable universe in exotic matter

i.e. it's not happening

can we really accelerate to 0.8c, then decelerate to 0c in 6 years without transforming passengers in apple juice?

>> No.2148612

>>2148435

Yes, because the objects inside the bubble are not really moving by themselves. The ship is carried along as space itself moves.

It's impossible. Any interstellar hydrogen impacting the zone of altered space around the ship would heat up the interior of the bubble like a mother fucker.

Orion was here, Alcubierre drive is for soft scifi faggots.

Looks like someone just learnt what the Kardashev Scale is and is dropping it in every thread he can to appear intelligent.

>> No.2148816

Just because the primary effect of an alcubierre drive would destroy the insides of the bubble doesn't mean there's no way to make it work.

You people are like cavemen debunking the use of nuclear weapons on the basis that if you hit your enemy with a nuke, you also kill yourself and your whole clan because they would obviously be inside the area covered by the fireball.

Um thats not even close to the same thing retard. Even a caveman would know how to set a booby trap and would just use the nuke as a mine far away from his tribe.

But bubble heats up and destroys everything inside the bubble, include the machinery that is maintaining the bubble then how the fuck it is supposed to transport anything anywhere. Also do we even have a hypothetical process to manipulate gravity to form the bubble in the the first place?
