First habitable Earth like planet found!

[Que-Ever]

I'd spend twenty years on a ship to inhabit a cool new planet.

How close are we to light-speed again?

We're so far away from light-speed that according to our very science, its impossible to reach it (let alone surpass it).

Its one thing to know its possible and just not have the means to doing it, but you know you've got a long way to go when you first have to refine your SCIENCE theories to make it even plausible.

 

[Que-Ever]

Sooo... twenty years is a no-go?

Can you travel as fast as light?

 

[Que-Ever]

Not without mah mutha****in x-wing, nigga.

 

[bbson john]

Can you travel as fast as light?

twenty one years then

 

[Terminator]

If we're ever seriously thinking about doing anything then it will be a sleeper or breeder ship, with the ability to set up a colony around the new star where they stay.

"Casting the seeds into the wind"

You have to engineer the civilisation so they do not wish to come back to earth, imagine being a child on this ship and hearing stories and seeing media about the big blue earth with huge oceans of water, millions of people and animals.......you'd be hell bent to turn the ship around and head back instead of heading towards a probably lifeless rock 20.5 lightyears away.

The soceity would have to be completely idependant of earth, it would have to remain all on boards choice to inhabit the new world.
Who would actually be willing to partake in this mission (who was sill mentally able)

And that's even before the considerations of extra solar travel.

And btw stephen hawking is going weightless in a parabolic flight.

 

[Vigilante]

It's not going to matter...nobody in our lifetime will set foot on the planet. Time slows down as you near the speed of light. The crew of the ship will have only aged 20.5 years, but on eart several hundred or even thousands of years would have passed.

Still very exciting, though.

 

[The Brick]

Yeah but you'd have to go really near the speed of light to have a significant effect. Traveling at 99% lightspeed makes the time go about 7x slower. At that speed the travelers would experience 3 years and earth 20.7.

The Earth has a mass of approx 6 x10^24 kg, a lot.
This other planet will have a mass of about 3 x10^25 and it's radius is approx 50% greater than the Earth's so it must be pretty dense! (like the average forum user )

Hmm, so the gravitational acceleration on the surface of the planet will be:


21.8 m/s^-2

Earth gravity is 9.8 m/s^-2

So it's just over double earth gravity. Or 2.2G, which isn't too bad I guess, the typical rollercoaster ride exposes people to no more than 3G.
Being under a constant 2G force might cause some health problems though!

I think you guys are focusing on the gravity a little bit too much :thumbs:

Besides, with the larger radius it works out to be only about 2.2 times as much gravity. (since radius is squared). 5 times the mass != 5 times the gravity. Gravity is G(m1*m2/radius^2).

All things being equal the mass is 5Earth, and the radius is I think about 1.5 Earth. So thats (5/1.5^2) which is about 2.2 times the gravity of Earth. That roughly means that things would fall at about 21.52 m/s^2.

You are a day late.
You lose.

Can you travel as fast as light?

yes, all i have to do is do the instant transmission technique and poof i'm there.

ZOMG WE CAN JUST LEIK CALL GOKU N HE CNA LIKE SAVE US LOLOLOL@@231

 

[soulslicer]

this is totally offtopic

half life 2 on such a world would suck..

the bullets will be like falling on the ground..
barnacles would be growing on the ground..
grav gun will just go pfft...

 

[phantomdesign]

if light travels at the speed of light, can we assume that no time has passed for the light particles?

Actually a more serious question . . . how much energy would it take to accelerate an average human body to 90% of the speed of light?

I'd be more worried about the perpetual light on one side of the planet, and darkness on the other. That'd suck a hell of a lot more.

That would actually be quite a usefull thing for power generation.

 

[Kester^]

But would suck for trying to get a good nights sleep.

e=mc^2
e=(76kg*10)N * (3*10^8)ms^-1 * (3*10^8)ms^-1
utopian answer ignoring escaping gravity and friction and such. work it out for an answer in Joules

Mass does not stay constant.
That's why you need like an infinite amount of energy or something to achieve lightspeed, and uh lots and lots and lots more energy to get close to it.

 

[bbson john]

mass= (rest mass)* 1/[1-(velocity/speed-of-light)]^1/2

I think I am a bit late.

 

[NeptuneUK]

Whatever, I feel ashamed to have forgotten all this shit.
It's not like I need to know it though

 

[Atomic_Piggy]

Well to travel at faster than light is imposible as we know, though many consider warp drive, such a device would require a horrific amount of energy - possibly more than the universe contains.

Don't worry, Scalar waves will deal with that little conundrum.

Someones got a case of the brain worms.

 

[99.vikram]

Actually, Marcus Chown talks about superluminal travel in one of his books - there may be ways to do it with a finite
amount of energy, using time dilation. We just can't test any of that yet, though..

 

[Terminator]

There are many other aspects of science that need to be adressed before any science for FTL can be possibly developed.
It is vital if we ever want any realistic extra solar exploration, personally i think it is unlikely for us to acheive it through a technological device, it is more like for us to develop time travel technology.

 

[Rapstah]

What we need is a black hole and a zero point energy field.
