## **Hello again Steemians!** #### How are you? I hope that very good! ### The subject on which I come to speak today are the ... White holes! ### ![](https://cdn.steemitimages.com/DQmXvcUWu52EHLQSuey2VLAjvpx2MvrYDcdAY5CfHFYC4VS/image.png) [Font](http://www.latinol.com/tag/agujeros-blancos)

I knew about them because of a doubt I had about the **Energy Conservation Law**, it turns out that my question was: _"According to this conservation law, energy is not created or destroyed, it is only transformed ... So, if the universe is constantly expanding, would not this result be a clear creation of energy? Or would it just be transformation of it?"_ Before this doubt I spoke with a professor and he mentioned the white holes as a possible source of expansion of the universe itself.

Me, someone who considered myself as a science buff didn't know something that seems to be super important in physics. ## So ... What are these white holes? ## They are just the opposite of black holes ... Ok, we all know black holes, or at least, we have an idea of what they are (Yes, they are those who swallow everything), then all of that, hypothetically, would have to come out on the other side ... Boom! That's where the white holes come in ... A kind of temporary exit from black holes ![](https://cdn.steemitimages.com/DQmTQMWsKaiBArJLCukgXXDJTFCHswDbDEWiqQj5iJyy8qw/image.png) [Font](http://ntcdelmundo.blogspot.com/2014/07/se-transforman-los-agujeros-negros-en.html) ## All this is a theory and they seem to be impossible, but ... It doesn't sound so outlandish, does it? # And you? What do you think? Do not forget to follow and vote if you like my posts! **_Today is the day that we tought yesterday_** @jpirela
