Lately I got a very unique plant but I have no idea what it is. Actually it looks pretty "normal", big leafs, green but a bit red. The special thing is the reproduction. It produces big seeds and shoots them. I wonder where it gets the power, because it really hurts when that plant shoots at you and its' so load when it shoots at a wall or at my window.
When you put the seeds in soil, a new palnt grows, obviosly.
I just want to know the name. Does anybody know it?
Thank you!

How would you tell that beneath a refrigerator door's layer of white-painted plastic is aluminum (without scraping)?

Could you use a magnet?

For the past months now, I have been getting myself into alot of space topics. I really am starting to find this entire topic very intresting. I started from scratch, with our planets, solar system, galaxies, and I kept moving on..

Where am I now? Well, I just finshed reading about the cosmic microwave background radiation, which seems to be really amazing, considering its existent everywhere in our universe. I have also learnt about how the universe expanding, with the evidence that stars around us appear red shifted.

I never thought I would dig deeper than this, but I am, and now I want to enter this field.

Anyway, yea so I am investigating problems with the Big Bang, and there seems to be three really big ones, that I dont seem to understand.

1.) Horizon Problem
2.) Flatness Problem
3.) Density Flucation Problem

Anyone here have any knowledge on these topics?

Thanks for reading.
