Lisa,

Concerning Black Holes.

There are two types of Black Holes. Some are only as big as big stars in their mass (relating to their gravity)

And others are as massive as millions upon millions of stars.

1) Can Black Holes get to full that things can fall out?

yes, this is one theory, but not the most common, well known theory. The theory is that pieces of black holes can be ejected/ thrown out.

2) Can black holes explode?

I’m not aware of any exploding Black Hole Theories but there are theories where Black Holes can throw off pieces of themselves. Again this the same theory described above is not the most common theory.

3) Can Black Holes suck in an entire planet/Solar System?

Large black holes can easily suck in many surrounding stars. Smaller Black Holes can also do this if the stars are close enough to the Black Hole. This would be considered a joining together process rather than sucking in process, however.

If you don’t really understand all the answers you could ask your mom or dad to explain them to you.

hey i am in 5th grade and i read a book on black holes by Dana Meachen Rau and i started wondering can a black hole ….
1. Get to full that things can fall out
2. can black holes explode
3. Suck in an entire planet/Solar System

if you have time can you try to post something to in form me on those questions, please and thank you

“Black holes can be low density. ”

It’s really beginning to annoy me that I don’t understand this concept better!

These Top 10 posts are freaking awesome and timeless. These are my favorites to look back through.

The deluded folks at the electric universe site take pleasure in bashing the black hole singularity idea. While singularities in theories point to a breakdown in the ability of the theory to handle an extreme situation, the electric universe crew don’t even understand basic orbital mechanics properly.
It is one thing to criticise singularities in black hole models, but quite another thing to utterly ignore a huge amount of data, observation and workable theories from the whole of astronomy on solar fusion, orbital mechanics and redshift.
