¿Y qué había antes del Big Bang?

[@karmaycholera]

"We are made of starstuff" and the starstuff is 13.7 billion years old... Hits hard

[@Cosmoknowledge]

I know right!? Everything is connected.

[@Altar-Ego]

How do we know how old starstuff is?

[@Kong3287]

According to Hinduism.... everything in the universe (including universe itself) is cyclical in nature....there is no end and the beginning....it all repeats itself in one gaint loop

[@Cosmoknowledge]

It MIGHT be.

[@TheSubpremeState]

I studied lots of religions aka cults and quickly settled on vedic philosophy if you could call it that cos it's so simple and very rational. The cycles of the universe is by far the closest explanation of the " universe" but where they are completely correct without any ..... particle accelerators is with the fact that nothing is real . Only awareness. The cycles are a few billion years off and they say nothing of the fact that most likely there are unlimited numbers of failed universes because the settings for this universe are one in a million or billion or more. Any number of things like gravity being too strong or weak or similar forces being off would lead to the universe never forming

[@Altar-Ego]

Why doesn’t the universe have a center? If we can rewind the matter back to a point, where would it be, and what’s there now?

[@Cosmoknowledge]

The idea is that everything that exists today, as far as we know, was tiny at the time of the big bang. That tiny thing didn't exist "somewhere". It was everything that existed. That tiny "everything" eventually grew up to become what we see today. Maybe in the future we will find out what caused the big bang. Maybe that big bang was just the collision of two universes. No one knows.

[@mariohoxha155]

​@@Cosmoknowledge I think the most probable thing is that we are in a simulation created by a way more advanced civilization that lives in a different/separated universe and our universe is inside a hyper technological computer and ofc inside their universe. And this might have been happening since forever, meaning that our super advaced creator is itself created by another civilization in the same way. So there might be a very large number of universes inside universes lined up. There is only one original universe and the rest are created by each civilization down the line and the probability we are in the original one is pretty low considering the fact that we have no idea how the big bang was triggered.

[@theamused8705]

They "think" they know.

[@shaheensiddiqui6983]

Underrated channel ❤

[@Cosmoknowledge]

I appreciate that. ❤️

[@zackgort8766]

Y'all call it the Big Bang, but what if was actually "God's Fart"?

[@TruthTheChamp]

How do we think we know** Corrected that for you.

[@RyanTaylor22]

😂

[@Cosmoknowledge]

[@DannyBoYfutube]

So why are galaxies moving at different speeds?

[@Arielnovak]

The farther a Galaxy is from us, the faster it is moving away from us.

[@AviaStars]

It's because the universe is like a balloon having dots painted as galaxies and when you inflate it then the closer dot to a galaxy move slower than the dot farther away and there are also some mathematical calculations that prove this theory: Light of M31: −0.001004(blueshifted) Light of M101: +0.000804(redshifted) So if we measure both of them then we get 75km/s/mpc Which means that a galaxy 1 mpc away will be exceeding faster than a galaxy closer to us than 1 mpc.

[@DannyBoYfutube]

@CaptainUjjwal-go9lk yes but it's been proven there are galaxies further out than others that are moving slower or faster than eachother? I get what your saying about the balloon example but all galaxies aren't uniformly moving at the same rate...as a matter of fact some are slowing down? This was one reason against the theory of expansion.

[@Cosmoknowledge]

Galaxies move at different speeds due to gravitational forces and the expansion of the universe.

[@cecilionembraceofnight486]

❤❤❤

[@Cosmoknowledge]

❤️

[@musicm6154]

We have no real role. We are just participating in the creation

[@Cosmoknowledge]

We are part of something bigger.

[@brenbansal2769]

THEORY ONLY! NOT EXACTLY!!!

[@Cosmoknowledge]

Of course.

[@litrehead]

Define theory.

[@leonardodakimchi]

Hahahahaha OK

[@Cosmoknowledge]

Cheers!

[@solkalibri1376]

If the universe was created by God, then God is older than the universe. But where was God standing when he created the universe?

[@SecureHandle]

I can’t tell what your purpose for this comment is lol

[@subaruairbag]

"I am the alpha and the omega, the beginning, and the end" is pretty straightforward.

[@pageracing16]

On the cross.

[@ananda8124]

Out of the universe... Actually, Universes....

[@user-gx5mn3su9q]

God is outside of the universe

[@marius1511]

God made the univers and all there is

[@MichaelMyers5678]

We also landed on the moon, apparently.

[@TX_BoomSlang]

Every single argument claiming that Nasa faked the Moon landings has been discredited. There are many things you can do to debunk your "apparent" knowledge for nonsense conspiracy theories.

[@PacoOtis]

Dude, your editor needs to realize we know what you look like so, maybe, a lot less face time of you?

[@Jaggerbush]

Ya know whats worse? No face and Ai narratives. Guess what buddy, there's a million of them out there - go find one. Enjoy to stock footage and mispronunciations.

[@tannercook4322]

Scientists don’t know how old the universe is. They just have their best theory of how old it is. Get your facts straight.

[@roysamuels9468]

🤓

[@cbirch7302]

"Scientists don't know why apples fall from trees, they just have their best theory of how apples fall from trees." Every scientific "theory" is on a spectrum of confidence, based on how much data there is to support any given subject. And a "theory" never becomes more than a theory, no matter how well supported it is. Skepticism is useless if you're only going to focus on questioning everything, and completely ignore the effort to find a valid answer. Saying "I don't believe it", is a lot easier than actually trying to find a valid answer. Sure, no one truly knows for sure how old the universe is, because no one was there. Just like no one can say for sure that electricity is the flow of electrons, because electrons are too small to see. But that doesn't mean I think electricity is a conspiracy.

[@elib5507]

We know how old light is that’s all we know

[@coreyyaromy8337]

I don't believe this for a second..... the reason is that something can't come from nothing. That being said if there was a big bag then it came from something not nothing. So there was already a universe and something happened to expand it

[@terrygiesler9065]

What's your explanation?

[@coreyyaromy8337]

@terrygiesler9065 if you can read I said there was already a universe and its only been expanding there was no big bang. The universe has always been here always expanding. Time is not existent so there is no way to judge when it's always been.

[@litrehead]

What's your credentials? Cite your sources! Support your belief with evidence and explanation.

[@Cosmoknowledge]

No scientists says the universe came from nothing. The big bang may have kickstarted the universe we know. There might be other universes. Something might've caused the big bang, like two universes colliding maybe. We just don't know. We have to be comfortable with the answer "No one knows until one knows".

[@coreyyaromy8337]

@litrehead credentials lmfao 🤣 probably higher then yours. Newtons law.
