Science & Mathematics Outer Space....

[The Sultan]

will the recent "discovery" of Kepler-452b a planet with similar properties to earth and it only a mere 1,400 mill light years away. thought id open a thread to discuss space and other things, im not much of a scientist / astronomer but this stuff fascinates me the sheers (unimaginable) size of the ours and other galaxies and number of other stars and planets out there makes you realize how luck, and insignificant we are..

 

[Gough]

I tried reading A Brief History of Time once, and lasted about a chapter, and a bit. That stuff is way over my head, literally, and metaphorically.

 

[The Sultan]

i dare say you wouldn't be the only one that has that book unfinished and collecting dust on the shelves , i prefer to watch doco's they "dumb" it down and make it a bit easier to digest.

 

[The Sultan]

just playing around with stuff in terms of space travel and distance etc (its friday arvo and im bored), these are figures ive pulled off the internet so bare with me

the fastest speed achieved by man made object: Satellite sent to Jupiter 25 miles per second
speed of light 186,000 miles per second.

thats like having a race b/w a car doing 60 mph ( 100 km/h), against a something going 0.008 mph (0.013 km/h) - the best i could find was a giant turtle that moves on land at 0.23 mph (0.368 hm/h), thats how far man is off in terms of travelling at the speed of light.....

Odd combination there to want to discuss.

think you'd find if that Stephen Hawkins A brief history of timewas written under the working title "Space, and shit..."

Ive noticed people do that, "whatever and shit." It's so annoying. Hawkins working title was a parody.

I managed 50 pages or so, a combination of 'it was too complex' and 'I'm not actually that interested' stopped me from going further.

i do apologies ill fix the initial post up, was hoping it to be a casual thread about space discussion rather then getting bogged down in scientific facts and terms...

i just made that parody name up, someone must of beat me to it....

No bestseller has remained unread by so many of the people who bought it.

I have listened to DR. Karl talk about it a few times. Quite unbelievable. He has had many different scientists co-hosting with him on Triple J and have covered many different topics regarding Space. There was one topic that intrigued me specifically, and it involved travelling at the speed of light for two years at a certain distance away from the Earth before returning. It essentially created time travel, as during that 2 year period travelling at the speed of light, 80 years would have passed by.

Realising that visiting other planets and spaceships and aliens will never happen in my life was the true end of childhood and innocence.

Dr Karl is a knob who likes the sound of his own fast-paced voice.

Maybe so, but you can't question his vast knowledge on a lot of scientific subjects, and has helped bring science topics into the mainstream and create interest with people where there otherwise would be none.

have to agree i like Dr Karl.. very smart man but not overly pretentious and keeps it simple yet entertaining.

 

[Tiff]

And to think ABHOT is basic stuff for dummies. I enjoyed reading it but I've forgotten all of it now. Universe in a nutshell was great, as it had pictures, and pictures are great for morons like myself.

I simply cannot even begin to describe how the much the size and weirdness of this universe blows my mind. Ugh.

Mankind has managed to draw a penis on another planet though.

This is the fact that really dumbfounds me as I try to put it into perspective:

There are more stars in our universe than grains of sands on all of the beaches on Earth.

Really makes us feel small doesn't it?

He's isn't condescending, obviously happy to share his knowledge and learn from others, all very good traits too.

Well put, science hour on triple J is always fun for me.

This page outlining the Fermi Paradox is probably my favorite website on the internet.

The Fermi Paradox (first articulated by physicist Enrico Fermi) is the apparent contradiction between high estimates, such as in the Drake Equation, of the probability of the existence of extraterrestrial civilizations and the lack of contact with, or evidence for, such civilizations.

I've spent the last 4.5 years doing a MSc. in Astronomy and Astrophysics just for the sake of interest. Best thing I've ever done - findings in this area are just amazing, and coming at an ever increasing rate due to Kepler, the Hubble Space Telescope (HST) and other new observatories. Once the James Webb Telescope (the successor to the HST) is up and running, we'll learn even more. Exciting times.

Was going to post the same. Some great articles there (some rubbish too). His Elon Musk ans IA ones are good reads.

this.... 100-400 billion stars in our galaxy (milky way) and 10 trillion galaxies in the universe.

I think that it is statistically certain that there is life out there, whether its intelligent life is another question all together.

 

[The Speaker]

Every time we hear of the incredible complexity of the universe, it can only confirm how unique we are to exist in such a perfectly ordered and functioning environment, and we cannot but glory in such a creation.

Considering the enormity of the universe and the high percentage of planets that harbor life, humanoid-like life, it's incredibly odd that there are no earth-like planets with humanoid-like life NEARBY. I am sure that there are solar systems where there are like say three earth planets next to each other....neighbors like Venus, earth, Mars, visiting each other regularly and advancing each other. Yet here we are completely utterly alone. Seems very improbable.
