How We Know The Universe is Ancient
The universe is precisely 13.8 billion year old – or so our best scientific methods tell us. But how do you learn the age of the universe when there’s no trace left of its beginnings?

Will Directed Energy Weapons be the Future?
What is faster than the fastest hypersonic missile?, well a beam of light, microwaves or subatomic particles but they are impossibly small and have almost no mass compared to a projectile. However, if you have enough energy you can make a weapon that works at the speed of light and in theory can shoot down anything projectile weapon we have now. So why don’t we have phasers like in Star Trek?, in this video we look at Directed Energy Weapons and what they can do now and in the future. Mike DoddI have a wide range of views and opinions. I have worked in a number of industries some of…

Hypersonic Missiles vs ICBM’s – Which is better?
The major nuclear powers have used ICBM’s as the mainstay of their defence strategy for 60 years or so and even built some form of anti-ballistic shield to protect against. But in the last decade or so a new type of hypersonic missiles have been developed that promises to make ICBM’s redundant but will they just fuel a new arms race as everyone one struggles to make them work in a reliable manner. So how do they compare to the decades-old tech of ICBM’s and are they any better? Guest AuthorAll Guest Author Posts are submitted or additional content Wave Chronicle has added to the website.

Will NASA’s Asteroid mission save us in the future?
“By failing to prepare, you are preparing to fail”, that quote by Benjamin Franklin certainly rings true with this current biological crisis but one day a large asteroid could give us all a very bad day. Thankfully we are starting to take the threat seriously and soon we will be testing to see if hitting a 150m chunk of rock weighing millions of tons can be knocked off a collision course with Earth with a 500kg spacecraft. This is AIDA, the Asteroid Impact and Deflection Assessment mission that will test out the theories on the double asteroid Didymos.

But they are also a very serious field of study for some of our greatest minds over the last century. So what’s the holdup? When do we get to wormhole ourselves out of here?

But just recently we discovered that its violent past was much more recent than we thought – and could even happen again.

How We Know The Earth Is Ancient
In astronomy, we talk about billions of years like it’s no big deal. But how can we be sure about timescales so far beyond the capacity for human intuition? Our discovery of what we now call deep time is very recent – as recent as our discovery of the true spatial vastness of our universe. And it came as scientists tried to measure the age of the Earth. What they found was as shocking and humbling as anything seen through the telescope.

What’s On The Other Side Of A Black Hole?
Normal maps are useless inside black holes. At the event horizon – the ultimate point of no return as you approach a black hole – time and space themselves change their character. We need new coordinate systems to trace paths into the black hole interior. But the maps we draw using those coordinates reveal something unexpected – they don’t simply end inside the black hole, but continue beyond. In these maps, black holes become wormholes, and new universes lie on the other side.

How Black Holes Spin Space Time
If there’s one thing cooler than a black hole it’s a rotating black hole. Why? Because we can use them as futuristic power generators, galactic-scale bombs, and portals to other universes. Black holes are self-sustaining holes in the fabric of spacetime. Space at the event horizon cascades downwards, dragging more space behind it, sort of like how water drags itself near the edge of a waterfall. In a Kerr black hole, space above the event horizon is dragged around in a circle – so less waterfall and more whirlpool. Water spiralling down a drain in a flat sink doesn’t know about the hole – it only knows about the motion…

How Do Quantum States Manifest In The Classical World?
This episode of space time is brought to you by the information flowing through an impossibly complex network of quantum entanglement, that just happens to mutually agree that you and I exist inside it. Oh, and Schrodinger’s cat is in here too. In quantum world things are routinely in multiple states at once – what we call a “superposition” of states. But in the classical world of large scales, things are either this or that. The famous thought experiment is Schrodinger’s cat – in which a cat is in an opaque box with a vial of deadly poison that’s released on the radioactive decay of an atom. Quantum mechanics tells…
