White Holes

Everyone knows of Black hole but most things in the universe have an opposite like matter and anti matter, therefore what is the opposite of something that sucks in everything including light. The answer is a white hole. White holes are very interesting for everyone as it is something that is difficult to imagine. What could be the function of the opposite of a black hole, this is what I'm here to tell you about.

A white hole is a hypothetical region of space time which cannot be entered from the outside although matter and light can escape from it. This must be difficult to imagine. If matter and light cannot enter then how can anything exit as for there to be an exit there must first be an entry. This question is what scientists are trying to answer and their success has been rather limited. Recently in fact some scientists suggested that the Big Bang might have been one massive white hole however due to the fact that the universe is expanding and our lack of knowledge of white holes, this theory has not gained momentum.

A white hole would attract objects just like anything else due to gravity but the objects would never actually reach the center and would keep losing momentum and would need more energy to accelerate. However eventually the amount of energy needed to accelerate past the resistance would be infinite and that number cannot be reached.

Finally my thoughts, I consider white holes to be interesting yet as there is no significant data I'll have to hold on before I put my thoughts down. If a significant discovery is found then I'll be sure to re-post about this topic.

Space Elevator - the Future of Space Travel?

Some space fanatics might know this idea first proposed by Konstantin Tsiolkosky at 1895. He proposed the idea of a tower reaching geosynchronous orbit. However to make such an elevator we would need a material that is both lighter and stronger than anything we have right now. However the developments with nanotechnologies have allowed for new materials to be created such as Carbon Nanotubes which might just be strong and light enough.


To the right is a diagram showing the system recently proposed. The climber is the elevator with the idea of centrifugal force used to keep the space elevator stable.

The benefit of having a Space Elevator is quite simple. Spaceships launched at that height would already be in space and therefore would not have to escape earth's gravitational field. Due to this they would have more fuel and would not slow down as they would be in a vacuum.

The main reason why the building of this hasnt even started is again simply the price. Due to carbon nanotubes being a new technology, it is quite expensive and to build something on a magnitude of a space elevator would literally cost an unimaginable amount therefore for now there is not enough support but I honestly see this happening quite soon.

In fact, a Japanese company actually plans to have it built by 2050. Obayashi Corp has quite the inspiring goal to have it built soon and I wish them all the luck in succeeding.

Below is another picture detailing the concept behind it. May we all one day be able to take an elevator to space.
