good for you! i'm a retired 'built-environment' engineer (or m&e, back in my day) and though always concerned with designing energy-efficient systems, they were often standalone solutions drawn around existing plans. growing environmental concern has lead to a much more inter-disciplinary approach over the years and it was around 2000 i noticed a lot of our new hires were environmental engineering graduates. i think all your hard work these last four years is about to pay off in spades. not only should you have a career for life, it is noble work you'll be doing. congratulations!

When I was a teenager I was consumed by the field of physics, fascinated beyond comprehension; life got in the way over the years and interest dwindled. The discovery of your videos has made me a child again. Every thought process seems to circle back to the history of the universe, and the unanswered questions in physics. It’s both my favourite channel on TRshow, and the last channel I’d want to find, because curiosity to that extent can make a person mad.. I’m still going to watch them all multiple times though 🤣

I wonder if the visible spectrum is an adaptation to the star that we ended up with. Like, if you were born on a planet with a more red star, I wonder if eyes on that planet had evolved to see a different snippet of the spectrum, like what we would consider as IR vision, meanwhile on Earth, they would think everyone has UV vision. It’d be kinda funny if there was some alien who’s weakness was getting sunburnt by blue light 😂
@user-ui6kv2np8i 2 aylar önce
100% correct. Life adapts to the star system (environment) where it was born, and indeed to the specific planet where it was born. If Earth had a heavier mass we wouldn't be able to move, likewise, a smaller mass would enable us to bounce our way around (relative to a human whose muscle strength / kg is what it is atm).
@jaspertuin2073 2 aylar önce
As others have said you are completely right. If you consider photosynthesis as ''seeing with plant eyes'' then we even have good reason to think the early earth had purple plants/life photosynthesising using a similar molecule to chlorophyl. This molecule worked better at the time due to the light from the sun to have a slightly different colour in it's earlier days, so it was more efficient to be purple coloured. I even believe this purple type was a simpler molecule to chlorophyl so it evolved earlier too, but not sure on this last part.

I’ve had a hard time sleeping for years. Between suffering from PTSD for almost 20 years since my deployments to war, also getting sober in 2016 after an overdose, and throw in your common daily stresses & anxieties, let’s just say it’s been difficult to get a good nights sleep…. I’ve tried all sorts of remedies to no avail… UNTIL I found your channel (being a big lover of astronomy, astrophysics & cosmology etc..). It’s completely changed my life (sounds hyperbolic to some I get it), but every night your videos put me at ease and eventually to sleep, good sleep too. I’ve watched/listened to all of them multiple times. I want to thank you for what you do. You’re not just educators, but so much more.

Such a simple, yet really quite relatable description of these unfathomably innumerous entities that require us to engage before potentially "zoning out" looking at pretty pictures. You content is virtually peerless, and I like to think it is less comparable to other channels, rather more an original place that thankfully makes what is usually ivory tower surrounded hard physics.

It depends on the size and temperature. It's reasonable to assume that some of the first stars were big and hot, and others were not so big and not so hot. Bigger, hotter stars will burn through their fuel in hundreds of millions of years, some even quicker, so yes, those ones are definitely gone.

One notion that I have always had from the moment I first heard about it, is that dark energies physical effect of expanding the universe is simply a direct consequence of all those virtual particles popping into and out of existence, of course the illogical part of that assumption is why should they have any effect at all if any energy they borrow is taken back in full. The so called Casimir force on steroids...but then perhaps somehow an exceedingly tiny percentage of that borrowed energy for their initial creation isn't paid back, leading to the expansion we see. Perhaps that energy is paid back, but on a different time scale than the Planck time we might expect it to be, maybe it is only paid back at the very end of matter's existence, when the universe is at maximum entropy , it catalyzes a snapping or inversion caused by countless eons of energy transfer from space time to another space time, or just time itself starts to reverse, or perhaps the moment of the big bang is simply the explosion of the last, and most massive black hole, that is the accumulated mass of all the mass from all black holes..

Unfortunately, the first stars were galaxy-sized and thus were so unstable, they either exploded or experienced entropy and so created the galaxies we see today, including our own. We may be able to see images of the very last of the first stars if we look far enough away, which is essentially looking backward in time. It's wild, but there it is - the farther away we peer, the farther back in time we peer.
