Possible Earth like planet found

[Kaliden]

Well, I better start heading there now to start my Communist leadership.

Plz explain, I am not getting how traveling through space is breaking the laws of physic.

Closest star: 5 light year
Galaxy size: 300 000 light years diamater
Closest galaxy: 2.5 million light year

Energy required to go at speed of light: infinite
Energy required to go faster than speed of light: sqrt(-1)


Let's say they are going slower than speed of light (3/4 of it). While it'a virtually possible, no matter made of element in periodic table is gonna stay intact at this speed, and space dust is gonna fuck you badly. You tell me they found technology to go around that? No problem...but it's still gonna take them 7 years to get to the Earth, assuming they live on the closest star.

Now, we are talking about the closest star, and not even the closest star that can possibly hold life, even less an advanced civilisation. Assuming they were lucky and landed on a star at 100 light years from us (this is an extremly optimistic number, because they would most likely be at hundred thousand light year, or even in another galaxy), it would take them 125 freaking year to get to us, than about as much to contact their own planet.


If you want to see space travel that isn't a permanant exodus and is at least slightly efficient, you have to find way around physics laws. However, the current physics model predict everything that happen within 0km/s and 300 000 km/s (light speed), and max gravity (black hole). Even if those formula arent definitive, they are still correct estimate of what happen in our universe, and about how much energy you need to "break" those laws.


The best solution would be to do like they did in Futuruma, make a vote to increase the official speed of light >_> But until then, have fun trying to make in real life "tele hax". Maybe we will someday find a loophole we can exploit without blowing up the universe, but I wouldn't count of it considering the tool we have on Earth are very limited (despite the fact we have about everything we can find in the universe)

Also, if aliens do visit our planet, they should do so legaly, or else terrorism happens. And abortions.

that's why we must start penning the alien work program before it comes down to amnesty

light travel is old news. put ppl in a ship, the space in front of the ship shrinks and the space behind the ship expands and it's still all within the laws of physics = speed of light

i seen a guy talking about this on some show on like, discovery or the science channel or some shit

cryogentics or some other system to keep people in suspended animation to actually survive this hundred+ year trip is a totally different story

this of course if we're only limited to the speed of light... if we attain it, i don't see a reason why we wouldn't be able to go faster than it

[Enkidu]

In order to travel in a spaceship that can travel the galaxy in 1 generation (preferably less for everybody onboard) you would have to be traveling faster than the speed of light.

No, if you traveled at the speed of light distance would be meaningless.

If you want to see space travel that isn't a permanant exode and is at least slightly efficient, you have to find way around physics laws.

No you don't. It's just distance. There's no reason that an alien life form wouldn't/couldn't have begun a mission a few million years ago to come to Earth or even just to this solar system.

Ok fine, how about I re-phrase it. If you want to travel in a spaceship, in one generation, and not have many hundreds if not thousands of years pass by outside of the spaceship, then you would need to travel faster than light.

What you hear on TV is vulgarisation made so simple they are often interpreted in the wrong way. What you just said is simply "what would happen if they accelerate close to the speed of light" and not "is it technically possible to go at this speed and how"

Now, explain me using that formula how you can attain it and/or go faster

e= energy required
m= mass of the object in movement
c = speed of light (300 000 km/s)
v= your current speed


If your speed is higher than C, you end up with a negative sqrt, which blow up your brain, and the universe that contain your brain.
If you go at the speed of light, you divide by 0, and break the internet, as well as many other thing.

Photons are going at the speed of light because they have no mass, something a human who want to keep an healthy diet can't do.

in the guy's theory we aren't moving, everything else is i think....

i suck at his explanation though, i'm not a physisist ><

if i could remember the show i seen it on i'd post it but it's not likely i will unless they show the show i seen on tv

Distance still mean something. It's instant for you, but the universe is still hundred of years older when you get out. Basically, you cant stay in contact with the people outside, because they will be dead for a long time when your trip will end.


Technically, there is no possible way for aliens to have started a trip millions years ago, because they had no idea we were there (and still don't). Mankind havent started emitting electromagnetic wave till very recently, so nothing in a radius smaller than 100 light year should be conscious of our existance. And this is assuming they are scanning the sky to discover new species, and were lucky enough to fall on our signal (very unlikely).
Unless they have a scanner that break physics laws....

[Bartylby]

WAAAAA i think it was a show about star treks technology and how the show influenced (and still influences) real life.

[Raineer]

Some other civilization that's been around for billions of years longer than ours (universe is supposedly 15-16 billion years old, so maybe they are 5b years old like our planet). Maybe they figured out wormholes and how to survive the trip.

The answer is most likely in learning how to suspend and reanimate life, like completely stop and later reanimate it...it could be done then.

However, we also have to realize we've found ONE planet that's 20 light-years away where this could be possible. The chances of that planet being populated with such a civilization is also quite small.

Another view is to not forget that it doesn't have to be a carbon-based life form, and possibly somewhere like Titan could be housing life as well. There are creatures here that live without sun or oxygen in almost pure sulfuric acid (just watch Planet Earth), it is true they are simple creatures but they also have predators. Who knows if such a life form could evolve further without said natural predators.

I'm surprised by the 'ruckus' generated by this announcement, we know countless stars being surrounded by planets...this one just happens to be close enough to measure the distance and size fairly precisely.

Maybe they had a telescope? We find planets and quite honestly our technology isn't even close to being maxed out.

i think by the next millenium when people look back at the "laws of physics" that we believe in so firmly right now they will laugh at how fragile those laws really are

haha, actually that "inhabitable" planet we see right now is the state of its existance in term of our understanding of time to be at least a couple million years old (because that's how long it takes vision--or light--of itself to reach us), which means that planet at this exact moment could all but have vanished

I've seen many shows on discovery chanel about space traveling, and many are closer to science fiction than physics. It's better to stick to physics book and actual equation than someone's dream.

If those kind of thing were possible, I'm certain I would have heard about them in one of my astrophysics class or in a book. They generally list every theories and possibilities, and sadly, there is no magic that will help us for space traveling

who knows what the future will hold right

besides exponential war disease and general plight

Yeah but when we look out and find things you're not just looking over distance but over time. By measuring red-light-shift we can tell the distance of a star (and therefore how old that light is you're seeing.)

Unless the aztecs/mayans were up to some crazy shit I doubt we have given off any easily-detectable emissions for anything over the last 100 years. There's always a chance there has been an intelligent life-form on this planet before us but it's not likely in the last 300 million years as geologists would have most likely found it.

Most explanations I've seen seem quite reasonable but it requires such an immense power source that it's just not feasible (not a cost-effeciency question, but just not feasible at this point in time).

The planet began forming what like 4-5 billion years ago? If the aliens had our technology they'd be able to see basic chemical composition of materials in our solar system. That alone would probably make it a worthwhile target for any advanced civilization looking for new planets or new life.

Now, explain me using that formula how you can attain it and/or go faster
