'Super-Earth' exoplanet spotted 42 light-years away

or they are giants with massive muscles.

I think that extra gravity would make you stronger and taller over time. Kind of like "the bigger you are, then the bigger your generations will become". It all depends on the amount of oxygen on the planet, or whatever they breath, if they don't need to use too much energy to breath, then they would have extra energy for their cells to multiply more. Expending allot of energy to breath makes you smaller. A more pressurized and oxygenated environment makes for giants. That is why the earth had HUGE everything in its distant past. More oxygen and at a higher pressure.

Great point.

I've often wondered about the supposed "Gas Giants" in our own solar system.....
Jupiter and Saturn etc are said to be large gas giants meanwhile when shoemaker levy impacted on Jupiter we saw some rather dazzling imagery of the impact and explosion.




Now, If they are truly gas giants why didn't the fragments simply disappear into the gaseous atmosphere under hundreds if not thousands of miles of gas to impact out of sight deep down below on the surface....? I'm sure somebody will explain it properly but in the meantime I'm thinking that there is a larger solid body under a much thinner than believed gaseous atmosphere...

Slayer, dont get me wrong, I am no expert, but I am fairly sure that those explosions were caused by the pressure applied to the cometary material. The material that penetrated the Jovian atmosphere may have contained exotic matter, which became explosive under the heat from the pressure of entry into the atmosphere (which as we know, is bloody enormous) or the pressure may have caused fairly benign chemicals in the cometary matter, to change under pressure and then become explosive.

Aside from the pressure alone, you have to remember that the void of space, is VERY cold, and the kind of pressure that we are told the Jovian atmosphere can create an awful lot of heat in solid material. The combination of the pressure and the thermal shock could have lead to the catastrophic explosions we saw in the incident you reference.

I can't speak for Alda but...

I feel many of our problems will simply go away. All of them? Hell no, We're still humans. I think that many of the perceived racial, cultural and hopefully religious differences will straighten themselves out when people realize that we are all "Earthlings" and the other species out there is from a completely different background and origins.

Two things...

1.) It could bring humanity together to move forwards because we will be for the first time a "Species" among many.

I'm thinking about the "Species" among many comment...

In Away I agree but what about when racism and cultural differences for between eathlings and the space brothers?won't it be the same thing just with different participants?

Ofcourse the unity we've formed as partners in space explorations would definitely make earths races closer.

A high gravity environment is likely to result in shorter broader beings, if anything. It makes little sense for a being in a high gravity environment to grow tall, since using biological resources to fight gravity with things like highly reinforced bones, high powered circulatory systems, superpowered musculature and so on, would be inefficient.

The best way for a being in a high gravity environment to grow, would be short and broad for this reason.

well to human physiology maybe. We are taller when we wake up after several hours of horizontal sleep. True. But I think that having denser bones, stronger muscles required to move around, would make your body get more room in every direction. Short and stout is good for cold climates, I think that a goldy locks zone planet, with more gravity, after taking into account the environmental conditions would be able to produce a bigger being if it had more atmosphere due to increased gravity.

I mean, look to pterodactyls. It is almost proven that they could not fly in our current atmosphere. People have studied their body mechanics, aero dynamics, possible muscle and body mass, ect, and they say a pterodactyl could not fly today. Yet, they flew.....we also know the earth had more, denser atmosphere during the time when they flew, more oxygen too.

So I am thinking that gravity is not as important relating to size, as is atmospheric conditions. Studies have been done on insects where they were raised in high oxygen content environments. The result was massive insects!. a higher pressurized and oxygenated environment makes the cells more efficient in receiving oxygen, and processing it, expending less energy in the process, making them multiply more.

SO, what I think happens is that with more gravity, a more dense atmosphere would develop and be maintained. Inherently if it were oxygen based like earth, organic life would spend less energy oxygenating its cells. The stronger gravity would require stronger muscles. Taking into account these two factors together, I think the result would not be short and stout. I think it would be a normal looking bipedal being, but with more body mass, more cells. The environment would dictate his bodies form, to better deal with heat or cold, but the level and pressure at which oxygenation is present in the cells due to the environment would dictate body mass.

Denser gravity, more pressure, more atmosphere, and so more body mass. The constitution of that mass would be normal IMO. Not adapted for cold conditions where short and stout are better suited for survivability.

There is almost everything we do not know about the effects of gravity on organisms. We have just begun to study the effects. We also don't have a great place to test it. We have earth, low earth orbit and then space. Centrifuges, but that is not great since it is not the same as constant force VS accelerated force.

Here is an interview I think you will like.

I don't understand how spin effects gravity, etc. But.....wouldn't a planet 7times our size not be habitble in a different way than on Earth?

reply to post by bigfatfurrytexan


What precisely did you mean by your question there BFFT? There are alot of ways life could be different. Did you mean microbial as opposed to fairly complex life?

If there is life on that planet, I hope for their sake they don't have oil. They had better be pretty open to accepting jesus too lol

It's planet Gendra. It's core isn't exactly molten magma, so this is a rare feature. The core's made from plasma, meaning that it's an artificial planet. Of all the possible species that can achieve artificial planet technology, I'd have to go with the Lin. They're highly advanced and they're friends with the Greys. The problem is though that the life that formed on that planet several thousands of years earlier is not intelligent enough to know that they are on an artificial planet. The Lin didn't foresee this, so they leave the species alone instead of colonizing it.

sorry friend I don't really. I'm sure someone will enlighten us both.
Thanks for the question.

reply to post by TrueBrit


Well, they are saying it is "Earth like". But being 7x bigger....makes it decidedly not Earth like.

My question is, what is the difference in gravity expected to be, and how would that effect life of all sizes. would you expect life to be more robust? Or to stay in water to reduce gravitational effect?

Please elaborate, I would love to hear your explanation of how you know this.

Its best to not bait the insane.

It is about 30% of why I come onto this site
This advanced alien species that created a planet that was colonized by another species before its creation.
Sounds legit. Aren't you even slightly interested in hearing the rest of the story???

reply to post by Uberdavo


I worked admissions in acute psychiatric care for 5 years. Being a 300lb former football and weight lifting star locally, naturally I got to work the craziest of the crazy.

I tell you all that to tell you this: i might be interested in hearing the rest of it.....but i have probably already heard it before.

reply to post by bigfatfurrytexan


I have to admit it does leave me a bit curious as well.

Though I guess if you hear the same story all day you might not be as interested

If theres human life on that planet theyre probably all midgets.

if you weigh 300lb here youd weigh 2100lb there. soooo the human inhabitants there probably weigh around 50 earth pounds

edit on 8-11-2012 by phroziac because: (no reason given)

So they when they come here, they will weigh 1/7th what they do on their home world? They would have John Carter-like leaping powers. That could get interesting. They would kick ass at the first Interplanetary Olympics.

I worked in disability support for just over 4 years. I weigh around 100kg and lift also. So I also got to work with some spirited fellows
This stuff still makes me lol though.

Sorry mods and OP for completely going off topic
