    Uranus hahaha

    @wavepsychic write a scientific paper on your finding, get it peer reviewed, suggest a more plausible model and provide evidence for it, then come back and say the current theory isn’t correct.

    Simply stating an arbitrary fact and claiming it means something it doesn’t is in no way proof that you are right.

  3. doctordave says:

    @wavepsychic The small tilts of the Sun and planets’ rotational axes relative to the average plane of the SS by no means “disprove” the theories of SS formation. Do you really think you are the first person to have noticed this? Do you really think there aren’t astrophysicists who spend their whole careers working on the dynamics of the SS who probably understand the details of the physics involved a little bit better than you do based on the handful of internet videos you’ve watched?

  4. wavepsychic says:

    @gangstacrak2 No you misunderstand. The accepted theory has a dust cloud forming into our sun and the planets from a dusty disk. The tilt of the sun disproves this. I’m not the one who claims space is flat. The Einstein cult with there trampoline model claims space is flat and curved by weight. I understand enough about gravity and angular momentum but that doesn’t prove the nebula disk model.

  5. gangstacrak2 says:

    @wavepsychic You obviously need a better understanding of Gravity and Physics. Both Jupiter and Saturn are also pulling on the sun with their own gravity. They are locked in their place by gravity and are spinning around it in perfect unison. As long as nothing ruins that, the gravitational forces keep them in place. The tilt of the sun has nothing to do with it. The earth is tilted and the moon doesn’t line up with it. Even so space isn’t flat, so tilt would effect nothing.

  6. washmlakid says:

    @doctordave Just speculating, why necessarily similar? Could there not be Jupiter- mass terrestrial planets? I haven’t seen the studies, I have a B.S. in Physics not in Astronomy, but I don’t know of a reason. It would go far towards explaining why the ones we’ve found are so massive and so close to the star. Could it possibly be a ‘failed’ binary falling into its twin? If possible, could you direct me to where I might find the info? Thank you.

  7. doctordave says:

    @washmlakid not that I know of… I think I was just using “jupiterlike” as short hand for similar size/mass/orbit. Although I can’t think of too many reasons we would expect the composition of jupiter-sized exoplanets to be too terribly different from Jupiter!

  8. washmlakid says:

    @doctordave Excuse me Dr., I was under the impression that astronomers had found Jupiter-mass planets, not Jupiter-like planets. Have I missed something in the popular journals, or on the web? Have we been able to get spectra on their atmospheres?

  9. doctordave says:

    @AegisDK Nicely put, Aegis. I like to think of it this way: I watch a lot of football on TV… Do you think the Jets will let me play in their game against the Colts this weekend? NO?! Why not? What makes them so special? Could it be perhaps that the act of playing football is somewhat more demanding than the process of watching it? I wonder, then, if participating in the act of constructing & evaluating scientific theories might also be somewhat more complicated than reading New Scientist?

  10. AegisDK says:

    @doctordave Hey! Me too! I totally agree with this wavepsychic dude. I too, know everything you know about physics, just by looking at NASAs website (just like wavepsychic). Can we both get… like.. you know… honorary PhDs in physics and stuff? I surf the net a lot and have a lot of oppinions about stuff. Ive looked up some stuff on existentialism on wikipedia as well, so maybe I can get like a bachelors in philosophy. Like a minor degree and stuff…
    (thanks for posting your lecture)

  11. pokerguy17 says:

    What is it with the idiots arguing with this guy? @_@

  12. doctordave says:

    @wavepsychic First of all, science never claims to explain every fact about anything. That’s not how science works. Second of all – philosophy? Philosophy is not how you determine facts about the natural world. Don’t agree? Read what Aristotle and Descartes had to say about the reasons planets orbit the Sun.

  13. wavepsychic says:

    @doctordave Does the sun even have tides?

  14. wavepsychic says:

    @doctordave Hello PhD in Physics. Everything you know about the planets in the solar system I have easily learned by looking them up on the internet. I have been too NASA’s web site and if you ask me all your PhD means is that you have been brain washed by older men with older views about the Universe. I am not prone too such brain washing. Just because they sound wrong? Do not belittle Philosophy. Your dominate theories make no sense and fail too explain EVERY FACT ABOUT THE PLANETS.

  15. doctordave says:

    @wavepsychic I am the “dude in the video” and I have a PhD in physics. What, pray tell, are your qualifications to critique the dominant theories of modern astrophysics because you think they “sound wrong”?

  16. wavepsychic says:

    @doctordave I don’t know if you are the dude in the video or not but I seriously can’t watch this whole video. The standard model doesn’t explain anything. There are lots of problems what this lecture. I am wondering what the students are thinking listening too this. It’s like they are just sucking it all in and not really thinking about how wrong it sounds.

    Why isn’t Jupiter or Saturn wondering into the inner solar system? The sun is titled 5 degrees and the planets don’t line up with the sun.

    funnyass questions lol

    Kids have posters of sports stars in their rooms i wana poster of Phil

  20. Afraid0fGhosts says:

    My question!! What do astronomers do???

  21. fertilizerspike says:

    You forgot to mention that about 99% of astronauts are in the military, so that’s pretty much a prerequisite to becoming an astronaut. NASA is a military administrative organization.

    SETI was created to eavesdrop on terrestrial communications. They monitor a billion channels just in the tiny slice of EM spectrum that we use for communication. Every signal SETI has decrypted to date has been terrestrial in origin.

  22. anonymouslybeautiful says:

    Just wanted you to know I Just sat here and watched all of your “Kids Questions” videos with my space-obsessed 5 year old nephew. He was enthralled with the way you explained things. When I went to show him another video about space he yelled, “NO! I only want the guy in the red shirt!” haha. Thank you for making science interesting. We made a homemade Space Camp bank last month and he has been saving up. I think we may have a little astronaut on our hands. :)

  23. AbdulRButt says:

    Thank you for answering these questions

  24. monkeyboy4746 says:

    Questions I have gotten from children while actually outside using a telescope:

    “Do the stars burn out in the daytime when the Sun comes up?”

    “That (Orion’s 3 belt stars rising on the horizon) isn’t stars, it is a radio antenna”

    “How do you get your telescope in your car?”

    “My daddy has one like that, but he doesn’t use it on the sky”

  25. kungfro says:

    I once asked a friend, “did you hear? Pluto’s not a planet anymore!”

    Her response was, “What, did it blow up??”
    :(

  26. mattrix2007 says:

    Hi, what would be the affects on earth if we got hit by a mass coronal ejection? if it was strong enough to penetrate the ionesphere would gamma rays give us radiation, or would it simply just knock out all our electronics? and is this possible it could happen?. thanx friendly guy.

  27. BitnikGr says:

    What?! He wasn’t teached in school about other planets in solar system? After 1995 astronomers found other planets?!!!! Gimme a gun, I’ll shoot myself!

  28. kidzcontrolRS says:

    at about 7:00 you start to talk about the type of telescopes you had a a kid, i was wondering if you could maybe show us the telescopes you have now?

  29. Gengar10000000000 says:

    They’re yes or no questions, you idiot.

  30. UneX100 says:

    Damn , you’re really friendly :)

  31. Germanboy567 says:

    and sedna

  32. andytom says:

    Yeah, and Makemake and Haumea.

    Although, if anyone even considers making Sedna a planet, he should be hung and dismembered. Just look at it’s crazy orbit.

  33. marker853 says:

    high school teachers are dumb

  34. kungfro says:

    And Sedna. And Charon! And Ceres. Ceres was considered a planet once, then it was discovered that it was the largest member of a belt of objects, called “asteroids.” Same EXACT thing happened to Pluto.

    If anyone still “thinks” Pluto is a planet, they HAVE to concede that Ceres is one too.

    And since Pluto and Charon both revolve around a common center of gravity, you can’t regard either as the true dominant body; they’d have to consider Charon a planet too.

    But… they’re not.

    cool, he’s Harald Lesch’s younger brother ?! 5*****
    >>Harald Lesch, Prof. d. Astrophysik, Observatorium München , Moderator v.”spacenight” Radio Bayern

  36. XSk8guyX says:

    It would be fun to throw water in the space

  37. andytom says:

    If Pluto would be a planet, then Eris would have to be one as well….
