Looking for SciShow elsewhere on the internet?
I don't know why it is necessary, when describing complex and fascinating concepts and theories, to rattle them off at breakneck speed. I have to pause the video frequently and replay certain sections in order to absorb the information more thoroughly.
I seriously doubt earth is the only planet with life. A very good percentage of stars actually have planets in their habitable zone, and have liquids that make abiogenesis possible. So it’s very likely that life is on other planets, we just haven’t found them yet. With the sheer number of planets and stars out there, I find it hard to believe that we’re alone in the universe.
You can believe that. I’m not going to stop you, but I recommend researching how we know these things. There’s more evidence than you might think. Religion and science can go together. God could’ve made this happen and made humans evolve into what we are today.
So a lot of crazy things happened over a very long time. Highlights include one cell eating another cell, fish with JAWS, fish on land, the invention of sex, learning to be a vegetarian, space bombs, everything killing everything, life restarts, hairy animals, grass being nearly impossible to eat, life uhh... finds a way (to eat the grass), and then humans steal the show. This was very interesting!
I like the topics of this channel, but I hate these teenage hipsters trying to pretend being smart and explain it. It's just so out of place, I cannot watch it. I just can't take them seriously with them so obviously trying to be all cool and hip and... "relatable" to young generation?
Well, that's an incredible number of factors that have come together at the right time for our species to arise.
Beyond grass coming at just the right time, there's the fact that the size of our planet is in a goldilocks size (large enough to hold an atmosphere, small enough that we can escape the gravity with chemical propulsion), the distance of the moon being perfect for regular solar eclipses and tidaly locked ... Either the simulation argument is correct or we really are one of the first species in the galaxy or perhaps the universe to get to this point.
well it's not that the context was made for us to appear, just that if it was slightly different other ( hopefuly inteligent) specie would have appeared and maybe would have asked themselves why the earth looked like it was made for them
People rarely think that all the species we know about during these ancient times barely reach 1% of the actual number of species that evolved during this time. All the information we get is from fossils and they only form under specific conditions, not to mention all the fossils that were destroyed by numerous reason over time ... Makes you wonder what horrific/amazing things roamed our Earth and we will never find out about it .
you also forgot to mention that our moon has an affect on how hot/cold our earth is. all those years ago the moon was very close to the earth causing it to be alot hotter then it is today. The further the moon is the colder the earth gets. Thankfully the moon is not leaving us at a rate which we need to fear.
I want to be the first to point this out to whoever deletes comments around here. When you start a show out with the 4.65 billion year garbage, you absolutely show how behind the times you guys are. What the creator Yahweh did to honor his house with the Gematria which is brought out only by his priests at the place he chose to place his name (deut 12:5) is unmatched and will be the greatest wonder ever presented to man bar none. Trillions of stamps of approval and agreement is what I'm talking about which no religion on earth can claim. If you are clueless as to what I'm saying, then you are going to be late and will surely arrive in the wrong attire. You have enough info in what I wrote you can find it out if you simply do the research, the rest is up to you, but I promise you will have cake on your face if you don't figure out what I'm talking about.
And soon you will find out that your plaid shirts didn't elevate your wisdom or knowledge one point and you were just a bunch of naieve kids who swallowed a bunch of lies from birth. One day soon when you find out that the creator himself is against doctors and frauds like einstein and all liars really, then you will become human, when you yourselves join those you make fun of today. I'll be there, it will be awesome, buckle up
Are you auctioning cattle or producing educational content?
Those dots and spaces between letters in books have an equivalent in spoken language too. Try reading a book without them? That is this video.
I love PBS Eons Series but this is unwatchable because every sentence is crashing into the next. It's like car insurance adverts on the radio. As annoying and unintelligible.
Sack your editing team. Ask for the unedited rushes back. Repost with natural pauses intact.
How can all this happen from NOTHING, A big random Bang. Also where did this material come from? Also how did you know the earth is billions of years old? No observable solid evidence. All this can't come from nothing. Intelligent design makes more sense
It didn't happen from nothing, there was the singularity from the big bang, which when it expanded(Or what you call, exploded) it was so hot that photons could become electron-positron pairs, aswell as gluons, which became quarks, which formed protons and neutrons, which formed Hydrogen and Helium, which formed stars, which compressed the hydrogen and the helium into heavier elements, which when the star went supernova spread them as space dust, which formed nebulas, which formed proto-planetary disks, which formed the Earth.
And we know the age of the earth based on the decay rate of Uranium in old meteorites, which puts the lower boundry on the age of the Earth at around 4.563 Billion.
Sorry, just had to turn it off at 3:05. This topic requires more pause, reflection and articulation of the subject. While the content is good, the delivery at 200mph without pausing, reflecting on the subject not letting your listeners absorb the content is not good. Your videos have potential, but please slow down. Thank you!
I am curious if species can adapt to increase there life. Why can't homosexual adapt? I am not trying to be hateful. You have creatures eating one another so the prey evolved to become faster and what's hunting the prey also evolved. So why can't homosexual evolved and be born into a sexuality they fine appealing?
My biology teacher at school did not except evolution. And although she taught it to us cause she had to, we also had to listen to her comments that "yeah, for me that seems impossible", "it is strange, but that's what the book says".
so sad :(
Could the Indohyus major have gone into the sea, because feeding there was easier then on land, due to the ice age created by the impact of the meteorite? I'd imagine that life forms in the water were not impacted as bad as the life on land. Hence the Indohyus major went into the waters to hunt, and evolved into the whales of today. Does that sound about right, or am I missing something?
WHAT?! you sir are wrong the Earth is only 5000 years old and a bearded space wizard created us in his image and sent his son to become a zombie to make sure we all knew whats up...
ALSO when you say "zircons" I'm sure you actually meant Christ crystals
ALSO ALSO everyone knows there are only two "era's" of Earth and they are the not dead Jesus times and waiting for dead but not dead Jesus times(now) but I'll forgive you for these mistakes....
Ahh yes insulting the religious as if you are any smarter than they are lol.
The truth is that our ancestors didn't view the world as objective matter and facts they viewed it as a forum for action hence the lack of focus on what constituted matter but rather the focus on how you should live in a manner that would ensure your survival and ability to work with those around you without killing each other.
They thought of things as you would think of them in a drama or narrative. This is why we had alchemy before we had science. As things did not simply have properties but meaning. Also you can thank religion for our pursuit of the truth as that is how we began to break away from our previous mindset to begin with. The pursuit of divine truth and honesty with oneself and those around you allowed people to begin questioning things that didn't add up rather than simply maintaining tradition without question. Sure you can say that religion has been used improperly but so has anything else human beings have manged to come up with. However it is the core elements and meanings of stories that are important and not how those in power misused them.
Our language still reflects this today when we say things like "He's tough as steel" in which you are not literally saying he's made of steel but rather he's actions are those which would could only be forged in fire aka difficult circumstance. etc Most of our ancestors understood this and it was not until our brains evolved the ability to perceive the world objectively that the misunderstandings such as what you are insulting with your comment began to occur. Human beings anthropomorphised their surroundings because that is how you passed on knowledge aka through myth, drama and stories as there was not writing at the time. This is why we have the old gods and why they are used to describe emotions that seem to posses a person when they take hold. Such emotions appeared to occur in any and everyone including animals hence they were omnipresent, all seeing and could posses beings. Again our ancestors perceived the world as a forum for action or as a story. As another example if I asked you to tell me about your life would you simply start telling me a list of all the things you own or places you've been or would you go about telling a story about your life orchestrating it from beginning to end? Our ability to view the world objectively is a new trait among our species and if you research tribes that have minimal contact with the modern cultures you will see that they still have a hard time being able to separate their stories or gods from their surroundings and nature.
Basically you insult the behavior which lead to your being able to articulate the insult in the first place because you are too stupid to understand that our roots require a different perspective of the world to be viewed correctly.
You are literally as single minded as those you insult and are no different than they are. The only real difference is that you and those like you are disingenuous an acting like an ass about it. At least they have tradition and faith to comfort them while you have nothing but denial of the fact that you behave as if you are a Christian even if you don't believe it. You are nested in your own mind which is nested in your family, then local culture, then national identity and finally the Christian ideal which functions as the cornerstone of the principles behind the ideal of the individual which is that each individual is of divine origin, worthy of respect and decency. If you don't believe any of that then you are in denial as you certainly act like it because if you didn't you'd be in jail.
In conclusion git fuked.
The class of drugs that Levitra, Viagra, Stendra, and Cialis belong to are called PDE5 inhibitors. They work by relaxing tight blood vessels, allowing more blood to surge into the penis and cause an erection, says Gregory Bales, M.D., an associate professor of urology at the University of Chicago.
The little pills do the trick for more than two-thirds of men with Viagra protects the heart (ED). They also work for guys who simply need them for a short time to get their “confidence back,” says Michael Eisenberg, M.D., director of male reproductive medicine and surgery at Stanford University.
