Black Holes and White Holes

[This post takes between 2 and 4 min. to read]


Like I mentioned in the last post- this post isn’t about biology. I don’t really know what this post falls under- physics? Space? That doesn’t really matter, though.

Anyways- back to black holes[and white holes. Never forget the white holes. I’ve heard white holes take offence very easily. Sorry, white holes]…

So… it’s black hole[AND WHITE HOLE!]time…

What is a black hole?

A black hole is a region in space where the gravitational pull is so, so strong, that it not even light or radiation can escape it. The gravitational pull is so strong because ALOT of matter is concentrated into a singularity- which has no volume or surface area. Getting an idea of just how dense a singularity is?

Parts of a black hole –>

Yes! Even black holes have an anatomy- but it is not really as complicated as a cell’s is.

  • Event Horizon- The event horizon is the boundary of the black hole. Once something crosses it, nothing can make it back out unless it travels faster than the speed of light. Black holes that do not rotate display spherical event horizons, whereas rotating black holes display event horizons that are distorted and nonspherical.
  • Ergosphere- The ergosphere is a region of space around a black hole where everything, even light, has to rotate in the direction of the black hole’s rotation. If you threw a particle straight at the black hole, it would not stay on it’s course, but instead begin to rotate just as the black hole does. [Not all black holes rotate.]
  • Gravitational Spacetime Distortion is basically because the black hole’s gravity is so immense that it distorts and warps the very fabric of space-time.
  • Singularity- It is the point in space where an unknown amount of matter is crushed into a single point with no surface area or volume, making it’s density infinite and gravitational pull extremely, extremely strong.
  • The Quiet Region around a black hole is where the space-time is mostly normal and unwarped.

Now, remember the title? Black holes and White Holes?

So far, I’ve ignored the white holes part. Now I better stop ignoring it…

What is a white hole?

A white hole is the exact opposite of a black hole- instead of eating away at stuff, it spews out stuff! Hypothetically, white holes are celestial objects that emit energy and light- like a time-reversed black hole. White holes [in theory] cannot be entered from outside [while black holes can…]

Why white holes?

See, Einstein thought that if black holes existed, then white holes must too! There is an opposite to everything in the Universe- serious people have joking people, there are Etruscan shrews for blue whales, Venus has Neptune -so, there have to be white holes! For years, scientists had been detecting signals from matter falling into black holes without realising it- what if the sky is teeming with white holes and we don’t even know it yet?


Some people, however, believe we have already found evidence of white holes- pulsars. Pulsars are thought to be rapidly rotating neutron stars which emit regular pulses of radio waves and other electromagnetic radiation. They are though to give out this stuff at the rate of upto 1000 pulses per second. People think these are white holes because they do exactly the opposite of what black holes do- they spew out things instead of eating away at things.

So… We’re done for today!

I wish there was more to know about white holes[to be honest, they intrigue me far more than black holes do], but there isn’t much information available…

Today’s space bonus isn’t a video, but a couple of links about black holes-

Yep. Bye.

hi! just a nerdy girl here. lover of science, english and learning on the whole. spreading knowledge is one of my favorite things to do! nothing in life is to be feared, it is only to be understood. now is the time to understand more, so that we may fear less. ~marie curie

  1. Hi! So, I realized one thing just now… I’ve done LOTS of biology posts. And this one’s a slightly physics-y post. But, I haven’t done a chemistry post. So, any ideas about chemistry-y stuff I could do- then PLEASE leave a comment. Thanks!

  2. wow this was fascinating … i’ve never even heard of a white hole! and after watching the movie interstellar, i’ve been a little bit more interested in black holes and how they work. this was so cool and filled with pictures and stuff that helped a lot in understanding! also, you seem like an awesome person ❤

  3. I know this if off topic but I’m looking into starting my own blog and was wondering what all is required to get setup? I’m assuming having a blog like yours would cost a pretty penny? I’m not very internet smart so I’m not 100 certain. Any recommendations or advice would be greatly appreciated. Kudos
