Cosmic Explosions | How the Universe Works | Science Channel

The visuals of magnetars and gamma-ray bursters are terrifying yet majestic. Thank you for reminding us that we are truly made of stardust, born from the most extreme explosions in existence. Science Channel never fails to deliver top-tier educational content that fuels my curiosity for the cosmos! 🚀✨🔭 Keep up the incredible work, looking forward to the next episode! 🌠🙌

We are lucky the Earth is in a quiet section of a galaxy that’s in a void of space. I believe life is everywhere in the universe but complex life is rare compared to simple life because of these crazy energy sources disrupting space

Out of nowhere, from nothing, we got everything. ✌️science✌️

This video really puts life into perspective… all our problems feel tiny compared to these cosmic explosions 🌌

Let there be light!

At 31:44 the guy says the ONLY way to create heavier elements is via supernovae. That's no longer correct. After we detected two colliding neutron stars in 2017, we've realized that that's another source of nucleogenesis. (See Season 7, Episode 1, "The Nightmare of Neutron Stars", one of my very favorites!) BTW, the biggest, baddest mega-flare minus the Big Bang is a quasar, not a GRB. (Season 6, "The Quasar Enigma" -- the episode numbering is confusing, but I have the season right.)

What if the Big Bang was just the accumulation of matter from the singularity inside a black hole? We’re just a pewp out the black hole’s backside?

Every time they say lucky for us or fir unknown reason, know that the universe was carefully designed and constructed

God and Science are the same. God did it....Science is us trying to understand how! I love this show still lol

For every billion particles of antimatter , there are "1 billion and 1"? "1,000,000,000.01"?

There was nothing, and it went BANG......you guys are so funny.

What if,that void the big bang started from was dark matter and dark energy? Leading it to expand the universe up until the big crunch and the big bang starts again? That's why you get dega vu'

So what I'm hearing is if you slow down a nuclear explosion into plant time you would be able to recreate everything that is and will ever be inside of that nuclear explosion so basically we are created inside of the Cold War of beings much greater than ourselves and since we have also recreated reality inside of our cold that sounds just like that Rick and Morty episode with the car battery

is it super nessecary to make the universe smaller than an atom?

bollocks

Ridiculous, but I'm open to other options

😂 Scientists always making more things up nobody else can argue with them about ?😂 You’d think they’d come up with a better name than “ Big Bang” . They’ve repeated the same things a billionth billionth times yet explained nothing differently. What a headache.

Hypothesis, hypothesis. If we can conceive there is no end, why can't we conceive there is no beginning. Finding the beginning, absolutely, they are modern time alchemists.

We've had 2 CME's in the last 2 years hit Earth.

Cosmic explosions always get framed as moments of chaos, but what stands out is how structured they actually are. These events aren’t random outbursts, they follow rules that existed long before stars or planets formed. What we call violence on a cosmic scale is often just the universe rebalancing itself, redistributing energy in ways we’re still learning to describe. Maybe the discomfort comes from realizing that creation and destruction are not opposites, but part of the same ongoing process we happen to be living inside.
