NASA to Make BIG Announcement Live on Thursday - Another Earth?!

Wouldn't the gravity on a larger world be greater? Meaning -- we couldn't really live there without being crushed?

Just curious. Did they say how far away this one is from us?

NASA has basically said, there's no doubt that life exists on other planets in the universe with the discovery of kepler 452-b.

So, I wonder how long until we hear:

"Woah, look right here...there's microbial life on these Mars rocks!"

*eye roll*

It's like they have to break us in really, really slowly to the idea that life is out there. They can't just admit what they've known for decades or something, as they think the world will somehow collapse.

Sorry NASA, most people are worried about paying their bills and what sports team is winning the game. Nearly everyone on Earth would simply shrug their shoulders if you announced real proof of microbial life. Even the Vatican has been preparing for this eventuality.

They said/guess to be double time the gravity of the Earth!

We woulnd not be "crush", but if one day some people go live their. They wil be way more stronger then us lol.

And their is so many possible planet! It's so nice!

From the graphic it appears the world is about 30% more massive than earth. Maybe a little more. I didn't hear the announcement, so I'll have to go by the graphics Jade posted.

That wouldn't necessarily preclude humans from existing there. Imagine you, but about 30% heavier. You've said you're pretty light so that would make you the same weight as a moderately obese man. And they have no trouble getting around for the most part.

Any bipedal intelligent life would probably be a bit shorter and stockier, but by no means is it impossible, at least, if it's within the 30% to 50% more massive realm.

ETA: Double earth gravity? Meh... Life would still be able flourish on such a planet, even intelligent life, but they probably wouldn't be bipedal.

Right, life could exist and have evolved there...but the stresses on our bones/muscles/back wouldn't be healthy for most people.

I'll be more excited when we can detect signatures of oxygen, nitrogen, carbon, ect...

if people want to listen! Q/A session starting

a reply to: JadeStarI am disappointed by your answer, you pretend to be a scientific person and yet show such ignorace of the real facts! A distance of 3.75 AU is NO distance for an object of sun size or slightly bigger. If we had another sun orbiting at Jupiter's distance none of our planets would have close to the orbit they have today. You obviously know a little about celestial mechanics and think you know it all. If you think calculating the orbit of an object in a binary star system is easy, well, go ahead and try it yourself.
Your arguments simply don't hold water.

Lol what?

Can you read? Do you know the difference between 3,750 AU and 3.75 AU?

#DecimalPlacesMatter

Not being a pain or nit picking, but you should know that in some countries the comma is used as a decimal point. Actually, quite a few:

Albania Andorra Angola Argentina Armenia Austria Azerbaijan Belarus Belgium Bolivia Bosnia and Herzegovina Brazil Bulgaria Cameroon Canada (when using French) Chile Colombia Costa Rica Croatia (comma used officially, but both forms are in use) Cuba Cyprus Czech Republic Denmark East Timor Ecuador Estonia Faroes Finland France Germany Georgia Greece Greenland Hungary (comma is official but both are used) Iceland Indonesia Italy Kazakhstan Kosovo Kyrgyzstan Latvia Lebanon Lithuania Luxembourg (uses both marks officially) Macau (in Portuguese text) Macedonia Moldova Mongolia Morocco Mozambique Namibia The Netherlands Norway Paraguay Peru Poland Portugal Romania Russia Serbia Slovakia Slovenia South Africa Spain Switzerland Sweden Tunisia Turkey Ukraine Uruguay Uzbekistan Venezuela

I would not be surprised if someone got confused......I know that when I lived overseas in other countries as a kid and a teen, it tripped me up a few times.

Yeah I really hope they turn every instrument they can to this new planet and try to detect the atmospheric signatures of life.

Wouldn't that be something? We spend billions trying to get evidence of microbial life in our own solar system, and we may find it hundreds of lightyears away.

They just said it's 14 yr/light distance? if yes, it's cool! I thought it would be more far!

a reply to: FreeQuebec86

14 light years away is a pretty "more far" distance away! But a blink of an eye if We can figure out how use worm holes, (if we haven't already done that)...

a reply to: FreeQuebec86

Listening now! Thanx for the link!! Syx...

a reply to: SyxPak

yeah it's really far, but when i see distance like "300 Ylight" these seem really too far. 14YLight a human could maybe survive the travel if we near speed of light.

if we can really use Worm hole, lol no more distance problems ever.

a reply to: SyxPak

14 LY ...

I don't know the exact math, but wouldn't that take a few hundred years for even our fastest theoretical ships to get there?

Unless we're ready for generational ships or discover a way to cryo-freeze people, I don't see us going there any time soon. Even an Orion powered craft would take 50+ years.

a reply to: MystikMushroom

Once we nail down sustainable fusion I don't think power issues will be a big problem. Though that universal speed limit would certainly put a damper on things.

its obvious that there is "life" as in organisms etc on other planets but intelligent life in my opinion is going to be extremely rare and maybe so intelligent that they are able to hide from us in plain site. intelligent life might be so far away or so disguised that its going to be a while til we have verifiable evidence unless nasa is hiding that info already.

Larger doesn't always mean denser. Density determines gravity more than size.

a reply to: ScientificRailgun

It would take a long time to get near relativistic speeds...

But once there, you could cruise around for a LONG time and not age much compared to everyone else. The Ender's Game books do a pretty good job explaining how someone can appear to be 30, but thousands of years have gone by because they were on ships traveling at close to the speed of light.

Then we'd also have the problem of stellar dust hitting the craft at those speeds. Ouch. Oh, and deceleration from those speeds too...

a reply to: MystikMushroom

Maybe we will be able to get near LY speed one day. Just half of it would rock!

And with robotic, we can send robot if we can't survive the highspeed travel. Just need a new tech for controlling them without a 14Yrs delay... xD I'm not english btw if i write nonsense!
