Sagan to Tyson's Cosmos - what have we learned? (1 Viewer)

[TommyKramer]

Seriously, I'm curious.

 

[DiStefano]

There are even more than billions and billions.

 

[Lutherman2112]

Young earthers will never understand.

 

[joey]

Dark matter and Dark energy to name 2 things.

But I'm no expert. Just following along and reading lots of Wikipedia since this series is really amazingly educational.

 

[lakerstan]

I thought the lead discoveries were eerily similar to climate change (and that appeared to be the subtext). Uranium decay is a little more clear to me now.

 

[Homer J Simpson]

Seriously, I'm curious.

So you're asking what advancements have been made in physics and astronomy in the last 30 years?

 

[TommyKramer]

Pretty much, yes.

 

[Monty Burns]

two of the biggest IMO....

planets are VERY VERY common, which gives more possibilities to life as we know it....

H2O and organic compounds are also VERY common in the universe, which is another boost for potential life as we know it....

 

[NCCommish]

Pretty much, yes.

Not even sure where to start. Do you have a particular branch or field of study to reference?

 

[Fennis]

I have a tardigrade fetish

 

[NCCommish]

I have a tardigrade fetish

Make roaches look like wusses. Radiation? No problem. Vacuum of Space? No problem. These little guys are tough.

 

[joffer]

when did Tang happen?

 

[Homer J Simpson]

Pretty much, yes.

Well, there's kind of a lot. Probably gonna need Pickles or another scienceguy to really get into it. I mean, just the stuff from the Large Hadron Collider could fill a library.

3 impressions I have at the end of every episode:

1. We are pretty insignificant when viewed in the context of the cosmos

2. At some point another asteroid is going to hit us, possibly sending us into distinction.

3. Our continued existence depends and finding other habitable planets.

We need to colonize other places if we really want to survive as a species.

sadly, I don't think we will make it in time.

I would hope we would get a medal.

Well I hope you're wrong but I wouldn't bet against you.

What would it matter? We'll all be long dead by then.

Will your children be dead? Will their children? Will all of humanity? Maybe thinking beyond the end of our nose would be a good thing.

 

[Doug B]

Pretty much, yes.

Might be easier if everyone just posts one good example of something in physics/astronomy that wasn't locked down in 1980. Here's mine:

Exoplanets. Planets outside of our solar system.

In 1992, the detection of the first two exoplanets was confirmed. Those first two were orbiting a pulsar -- it wasn't until 1995 that exoplanets were positively detected orbiting a main-sequence star. Main-sequence stars orbited by multiple planets were first detected in 1999. In 2008, exoplanets with atmospheric water were first discovered.

Detected exoplanets were either gas giants or so-called "super-Earths" until 2009-2010, when NASA's Kepler space telescope found the first rocky, Earth-analog exoplanet. In 2013, data from the Kepler telescope allowed astronomers to map the surface clouds of an gas-giant exoplanet approximately 1200 light years from Earth. Also in 2013, Kepler telescope data greatly expanded the number of planets found with atmospheric water.

The next milestone is to find an exoplanet with atmospheric oxygen.

Why?

I won't be around to remember it at all. With my consciousness gone, what does it matter to me what happens to the rest of the race?

Good thing we weren't counting on you to start civilization I guess.

The majority if not all of civilization was created out of selfish desires or survival necessity, hardly some far reaching dream of helping further the species.

In fact I'd say about 0.00000000000000000000000001% of all major advancements in humanity was done with "survival of the species" as a motivating factor.

Then you'd be wrong. Agriculture is about survival of the species. Cities are on outgrowth of the village which were created to protect people from all the dangers in their environment again about survival of the species. Science at it's foundation is about helping humans survive by understanding their world.

Just finished The Demon-Haunted World. What a fantastic book. Sagan was a true visionary.
