Ask me anything about Astronomy
As an aspiring astrophysicist, I know a thing or two about space. I also know that space is super cool and almost everyone I've ever talked to wants to learn more about it. This is a technique of studying I do with friends and family, as by teaching something that I know, if better cements that concept into my brain.
Fair warning: I don't know everything, and I will let you know if what you're asking is out of my grasp. But I'm pretty good, so fire away.

3 RepliesHi. This is a telescope question. I have been into astronomy and stargazing for about 5 years now and at this stage I have pretty much chosen the career for my future. I currently own a Celestron 114LCM telescope. Its a 4.5 inch reflector with a focal ratio of f/9 making it near suitable for planetary viewing (f/10) It can clearly see the bands of Jupiter the Cassini division of Saturn and the blue-green hues of Uranus and Neptune. I also have a €399 Neximage Burst for it too. Overall its a great telescope and I love it. But as it gets older I would want to think of getting a new one. What should I buy next? A Nexstar 5SE or a 6SE or make a bold move for the 8SE?

1 ReplyIt is indeed super cool, but how cool? Do you know whether there is actually anywhere in space that hits closest to absolute zero? Also, when will we get affected by our galaxy's collision with the andromeda galaxy?

3 RepliesDo you think life existed in Mars at some point? It has plenty of frozen water, however most in canyons and cannot get any sunlight, or completely underground. I think that Mars use to have a much larger atmosphere. In the summer, it reaches 90 degrees Fahrenheit. With greenhouse gasses, this could theoretically reach Earth-like temperatures.

4 RepliesI'm very interested in this theme and might be doing this as a job in the future. So thanks for making this Thread. But now to the actual question, which theory of the “Multiverse“ is the most realistic one? Maybe give your own opinion into this also.

1 ReplyEdited by Civilian-Druid: 4/6/2016 4:09:14 PMEnceladus and Ganymede show great signs of being able to support life. Why then is focus on Mars which at one point may have been able to sustain life? Also, is Olympus Mons extinct? I can't remember reading anything about Mars plates being active or not.

3 RepliesEdited by neptune: 4/6/2016 3:49:26 PMWhat's your speculation for what happens in a singularity? Personally, I've always kinda hoped they are inter-dimdensional portals, and they'd spit you out in a different galaxy... I mean there's a smb in every galaxy. It just makes sense... but more it's more likely that I'm just crazy. Oh and I have another thing... so in Star Trek, they have warp speed, which is faster than light travel. If you are moving faster than light, and you travel for, say 5 minutes in one direction, then stop and turn around, wouldn't you see yourself from before you traveled faster than light 5 minutes ago?
