not as much tech news as epic news.. NEW PLANET ? (9)

[mikat]

Another planet humanity can f*ck with. 

Another planet you or i will never reach

[AresKrieger]

Actually more interestingly a tenth planet has also been hypothesized as well, but just like this one the only thing we have to go on is gravitational affects (and the tenth's is more minor due to distance) either way more searching is needed for conformation of anything.

 

[GeekJump]

yes because gravity is constant, and faster then the speed of light...

 

You say that like I'm Neil deGrasse Tyson or some shit >_>...

 

My degree is in neuropsych not space and stuff

[givingtnt]

What if Pluto was the moon!?! Illuminati confirmed on Planet X!?1?!!?!?!?1/!?!?!?!1?!?1

uh. no makes no sense

one could say were the sun's moons. but no. were planets

Do you want me to give you gravities constant? Also I'm sorry I've just been doing my physics homework for the past couple of days... Also its faster then the speed of light because as soon as the source of gravity move the other object reacts. Which is instant, and not based on the speed of light.

How do you know?

I get the gravity part, and the speed of like part, but I don't get how they used gravity to guess there is a planet there.

How long till we find the 10th planet? We've been discovering planets in our solar system for hundreds of years.

How dare you deny pluto its just right Fight for PLUTO.

[Lazmarr]

-snip-

Pluto was reinstated as a planet...this is technically the 10th

[Clear17Mud]

They see the orbit of the planets and say this is impossible with out another celestial body. So its just a theory.

Last I had heard was that the 10 planet was the size of Jupiter and much farther away... Because that's how the math works. It could be either.

Astronomy and Astrophysics blows my mind sometimes. One can infer a planet exists by gravitational pulls? I mean, I get it but wtff?!?! That is crazy

 

I like this news :3

 

That is how Neptune was discovered.  The observations of Uranus made it clear that there was another planet, and shortly afterward Neptune was spotted.  And the discovery of pluto was fueled because Neptune wasn't behaving the way it was supposed to.  What is interesting about Pluto is if you look at it's estimated/measured/inferred mass over the decades, you'll notice that it's been shrinking. So much so that many have concluded that pluto was no longer sufficient to even pretend it explains Neptunes orbit, and bingo, kuiper belt.

 

As for the news.  It better be a Mass Effect Relay, I wanna get out there.

You have "geek" in your name and your avatar is an alien. That just screams astrophysicist to me.

[mikat]

well, i'm predicting

I get the gravity part, and the speed of like part, but I don't get how they used gravity to guess there is a planet there.

There is two ways going about explaining this.

 

First way: Classical 

 

By that, I mean that we can measure or observe a force being exerted on instruments such as satellites. There are satellites whose sole purpose is to collect data on the the gravitational pull of celestial objects (Planets, stars, etc). Sometime we even observe small variations, or wobbes, in nearby space objects to detect the presence of an gravitational force being applied on an object. From there, this data can be reconstructed to statistically hypothesise that a planet is there. 

 

Second Way: New Physics

 

Basically space is like an fabric. Objects displace this fabric. Since celestial bodies, like planets, travel in elliptical orbits around their center, a path (indent) is created in the fabric. This looks like this:

 

We can hypothesize and theorize the location of planets based on the disruption in the space fabric. This is based on Einstein's Theory of General relativity which describes these gravitational waves. 

[Serin]

To add some simplified example to Ionbasa's comment:

[patrick3027]

Interesting, it seems like it's a rocky planet unlike Neptunus, Uranus, Jupiter and Saturnus.

Let's get a greenhouse effect going and colonise it.

touché....But then again, was Mordin an astrophysicist!?!?

Now this makes more sense.

Where the balls did you read that the force of gravity has a speed faster than light

[ionbasa]

Just wanted to point this out:

In classical mechanics gravity has no 'speed' per say. Rather, the force felt/observed by an object is for all purposes instantaneous.

 

So if the sun magically disappeared , Earth would get flung out on an perpendicular motion from its orbit at that instant. We'd still see the sun as light takes time to reach earth(~8.4 minutes ).

 

In general relativity gravity propagates at the speed of light. So, if the sun were to disappear, we'd feel it and see it at the same time.

 

So, it depends on how you 'look' at it. But for all physical purposes, general relativity is the 'correct' answer, so gravity doesn't travel faster than the speed of light. Maybe the person you quoted  hasn't gotten to the required coursework to know that.

 

NOTE: In high school and most college intro classes, newtonian /classical mechanics is all that is taught.

well you see do you remember the "god partical" because that wasn't what translated that information, but gravity is the only thing that can go faster then the speed of light, but I can't remember just 1 place I got this information, but... how do you think black holes work... GRAVITY... (easiest to explain example)

Gravitational waves propagate at the speed of light. Not faster nor slower. It's all in General relativity.

 

The higgs boson is just an subatomic structure which is an excitation of the higgs field. You must be thinking about gravitons, the theorized elementary particle that makes up gravity fields in quantum mechanics.
