Astrum Space · Scientists Put a Time Limit on the End of the Universe · 11 Sep 2026 podcast

But if it only speaks through gravity, matched

Then the solar system may remain the only local avenue to understand the power that controls us, and ultimately our fate. matched

A fate that may not only be written in the oldest light we can see. matched

but hidden in the quiet, precise motion of worlds much closer to home. matched

I'll see you back here in 31 years to check in, if we make it. matched

Astrum Space · What We Detected in the Strangest Quantum Experiments on Earth · 7 Sep 2026 podcast

Our Sun is a colossal ball of hydrogen

and helium 330,000 times the mass of Earth. voice-verified

But the Sun doesn't just form the center of our solar system. voice-verified

Every second, thanks to the nuclear fusion reactions in its core, voice-verified

it generates a gargantuan 386 trillion trillion joules of energy, 175 quadrillion of which reaches the Earth in the form of sunlight.

And

it's this radiation that provides pretty much all the energy we use as humans on Earth. voice-verified

It underpins food chains, drives the weather systems we use for renewables, and of course, it's sunlight captured by ancient plants long buried in the Earth's crust that we're still utilising when we burn fossil fuels. voice-verified

But what if there was a different way to power our modern industrialised society? voice-verified

What if, instead of relying on photons that have made their way through 150 million kilometers of space, we could create the nuclear fusion reactions that keep our sun burning to grant us an unending source of clean and efficient power? voice-verified

What if we could make a star on Earth? voice-verified

I'm Alex McColgan and you're watching Astrum. voice-verified

Join me today as we delve voice-verified

into the heart of our star and find out if we truly ever could unleash its power on our planet.

Humanity, it seems, has a power problem.
