[Q&A+] Seeing the Oort Cloud, Rogue Planet Nearby, Knocking the Moon Away | Q&A 329
Can a giant asteroid knock the Moon from its orbit? How good does a telescope need to be to see the Oort cloud? What are the odds of a rogue planet hiding nearby in our Solar system? And in our extended Q&A+ version, can we be sure that we're alone in the Universe? Answering all these questions and more in this Q&A show.

Hi Frazer. We know that nothing can escape the gravitational pull of black holes and once past the event horizon, nothing can escape so my question is, do black holes influence the expansion of the universe? Thanks Darryl Griffiths 😊
Hi Fraser, isn't the ration between normal and dark matter is 1:5 (instead of 1:10) ?
If a black hole is rotating at the maximum rate our physics allows, and if our physics is right, what happens if a sun impacts it at an angle that would otherwise increase its spin rate?
Saturn, absolutely. It was quite moving.
Its been messing with my head now... So no full stream unedited and now I im removing overtime and missin it... ? WTF is happening
Hello Fraser, I am sorry but the equations of relativity do not say that time goes negative if you travel faster than the speed of light. The equations say that time becomes Imaginary. This is the square root of a negative number. We have no idea what Imaginary means in terms of time, but it is not negative, or going backwards in time.
Another great Q&A show.
