1. ## beginner questions

Thanks for that diagram. I didnt know that they evaporate when not actively being fed. Yes I would like to read that article about hawking radiation. Every piece of new information is a learning experience. So if you could find it, I would really appreciate it. Thanks
2. ## beginner questions

Thanks George - So basically with Newtons theory the object in 10 years would be traveling at almost 10 times the speed of light, with a constant 1g acceleration whereas Einstein says it could only reach to 0.995 of light speed. Theoretically Einstein describes time travel better with more accuracy than Newtons theory? Okay I know you guys have tried to explain but I'm still asking why? I mean in theory if an light can travel that fast, isnt it also possible that perhaps something out there that we cannot see, can travel twice as fast or more? I mean if something is traveling 10x the speed of light, chances are we're not going to see it right or our brain might not even be able to perceive what we saw right? themos - I mean if a blackhole existed at around the time the universe was created and grew bigger and bigger and never stopped but just kept sucking up everything it came into contact with, then how could the universe still exist? Especially with more than just 1 blackhole. Of course theres the argument that the universe is just too big, I suppose..
3. ## beginner questions

Thanks for your replies. It clears a little bit up now that I know that Newtons theory cant really be applied to this scenario. themos, I know there is no specific theory that can satisfy that question. I was just wondering, if all that mass when into something and that something kept growing from the beginning of time, it doesn't make much sense to me how everything would still exist. Which is why I think that although destruction appears at the beginning of the black hole, a reverse should be happening on the other end of it. I also read in a book that black holes could lead to another universe but that its also unlikely. I guess the answer to that will not exist in our lifetime...
4. ## beginner questions

Hey all! I have a couple of beginner questions after reading some basic astrophysics. I would really appreciate it if somebody could give me some answers. 1. Does Newtons 3rd law apply in space (to every action there is an equal and opposing reaction)? I dont mean on other planets, moons or entities, just space (the gaps) between the objects. 2. Assuming that this law does apply, wouldnt that mean, that at the end of a black hole is not really destruction but creation? I read that some people hypothesized that at the end of black holes would be so called white holes and that they could've been quasars? 3. Assuming that this law does not apply in space, wouldnt that mean constant acceleration (with necessary fuel) is not impossible and an object traveling through space would eventually reach or exceed the speed of light, should it be able to survive at those speeds? Ok the last one is kind of stupid, I was just wondering, so bear with me please: Could it be that the black matter in space between galaxies is just expanded black holes that have reached a, well 'critical mass' or something? Would be great if anyone could help me out, I understand that everything is not so simple as I have put it but I'd like to learn Thanks
5. ## voyager images?

I just read on NASA's page that the last images made by the voyager missions were on Valentine's Day 1990. It was a 'map' or 'family portrait' of our solar system. So there have been no pictures made by either voyager 1 or 2 of objects near or outside our solar system after 1990..
6. ## voyager images?

Hey guys, thanks for the suggestions. I tried both those websites and I find some pictures, that I've already seen before. I was wondering if they had an archive of pictures, that can be accessed online. Maybe I'm just too impatient to find it
7. ## voyager images?

Hi everyone! Does NASA allow the public to view images captured by the voyager spacecrafts? I've seen the planetary pictures made but it would be more interesting to see other images. Is there a webpage for this? Thanks
8. ## 3 telescope choices..n confused!

Thank you for your input luke
9. ## 3 telescope choices..n confused!

Thanks Wurzil, yes they're based in Germany but are a little pricey. I still have had no reply from the R-90 owner and I've found a couple of newtonian reflectors on ebay, that I might just bid for. Theres a 114mm/900 tube there.
10. ## 3 telescope choices..n confused!

No those 3 scopes are second hand scopes. The celestron was already sold and I've emailed the other 2 telescope owners. Hopefully will get a positive on at least one.
11. ## 3 telescope choices..n confused!

Wow Stellarium is really cool! I didnt know there was a software like that and its free! Well at least, I'll know where to look for what Thanks jerokane
12. ## HI!

Hey!! Thank you for all those welcomes This seems like a good place to stick around!
13. ## 3 telescope choices..n confused!

Thank you for your motivation JK and all your suggestions. I'll download the software you mentioned. Just brought back home a lot of books on astronomy from the public library haha Good day!
14. ## 3 telescope choices..n confused!

haha thanks! I'll have to find all those first but Im really hoping that this time around I wont end up abandoning it for another 15 years. Yeah no problem finding Bresser scopes over here. Second hand they're quite cheap and if you buy them new from the Meade online store, postage is free!
15. ## 3 telescope choices..n confused!

No I dont live in the UK. Right now I live in Germany. My very first telescope blunder was in the US. I bought it from SEARS. I guess I could buy it from online shops in the UK but the cost of postage and the risk to the telescope, would be both a little a high. I'd check for the Skywatcher Evostar 102 over here. Thanks
