Breakthrough Junior Challenge – Black Hole Information Paradox

Dear all,

I have decided to submit an entry to this year’s Breakthrough Junior Challenge, which is a competition in which you have to make a 3-minute video explaining a scientific concept/idea to a general target audience. I chose the Black Hole Information Paradox as my topic because I was reading into the Holographic Principle over the summer and fell in deep haha.

The following is my video – I hope you like it and could give it a thumbs up on Youtube if that’s a possibility.

And..check out the Breakthrough Junior challenge website!

Leave some thoughts below!

Carl Sagan

My life is a little hectic at the moment due to UCAS (University Application) deadlines and so on. While in the middle of composing my personal statement, I found a small tribute text I had written about Carl Sagan last year as a response to the following question for an application.

If you could have dinner with anyone alive or dead, who would it be and why?

And I followed up with this:

I would love to have dinner with Carl Sagan.

Short Rant about Entropy and the Universe

1entropy.gifOne of the most important laws of Physics is perhaps one we have all heard once in a while – the second law of thermodynamics.

This law states that the entropy – in a closed system – in which we can infer as the Universe, will always increase.

A common misconception with the term entropy is that it is a measure of disorder. A “disordered” state does not necessarily mean that it has high entropy and vice versa. Entropy is rather the number of ways particles can be arranged. We can take tea and milk as an example, as many people do. Looking at the tea and milk system, at the instantaneous moment when you pour milk into tea, it is perceived to have low entropy, this is because the milk molecules are virtually sitting on top of the tea molecules. When you wait for a second or two until the milk starts to blend and dissolve into the tea, the system begins to increase in entropy, because there are so many more ways for the milk and tea molecules to arrange themselves in this sense, rather than being stacked on top of each other.

Black Holes #1 – Singularities and Hawking Radiation

The Black Hole from Interstellar

Black Holes seem like something that only exists in Science fiction, like Dark Matter and Energy, however, these astronomical objects are in fact at the heart of theoretical research within Cosmology. Research involving Black Holes may likely help us uncover more about the mysteries of Quantum Gravity, something Physicists believe to be the Theory of Everything.

In simple terms, a Black Holes is a region in which the gravitational influence is so strong that nothing, not even light, can escape its pull beyond the Event Horizon, which means that the Escape velocity is essentially greater than the speed of light. Escape velocity is the speed in which an object needs to travel at to escape a gravitational field, e.g. the Earth’s.

Discussing Time Travel

dfhshrshtsrLast post I did a short guide on Special Relativity and I briefly mentioned time dilation which touches on the concept of Time Travel. Time Travel, like Parallel Universes or Teleportation is something that at a glance seems improbable, “beyond the boundary of physics” and just a complete work of science fiction, but interestingly enough all three of these areas are studied in-depth within the field of physics.

Einstein thought about space as a piece of fabric and essentially called it the fabric of space-time. We can think about time as a dimension, like length and width and height, there is a temporal dimension. Time travel is simply our progression through this dimension and we are all time travelling at this very moment because we are experiencing the passing of time. Time travelling to the future is a crucial everyday task, and it happens more naturally than people may acknowledge.

Parallel Universes #2 – Greene’s Classification of Multiverse types

maxresdefault

In the previous post I introduced the Many World’s hypothesis of Quantum Mechanics which is a possibility of parallel universe. Exploring possibilities of what types of parallel universes could exist may sound like science fiction however like time travel and teleportation, the idea of parallel universes is often the subject of mathematical and experimental investigation. In a recent episode of Star Talk, Michio Kaku mentioned the joy of trying to defy the impossible in his everyday job as a theoretical physicist.

The term parallel universes could seem vague and confusing to some. Exactly what is a parallel universe… Alternate timelines? An entire universe on its own outside the observable universe? Do parallel universes of all possible historical timelines exist? The matter is a little complicated. Physicists often use the words parallel universes to describe several different hypotheses of a number of possible universes outside our own combined to form something called the Multiverse. Hence the idea of parallel universes arises from the multiverse theory itself.
