Brian Cox on How We Measure the Age of the Universe?

[@paulford9120]

Imagine showing this all to physicists from as little as 100 years ago. They'd be astonished how far we've come.

[@fumanpoo4725]

Bong talk is similar.

[@Nicklessization]

They all fit because we're using the same idea and principles.

[@suryatejach007]

Nah not really. Age of universe is based on red shift of far away galaxies and finding how fast they are moving away and backtracking it to bigbang. Age of sun and earth are explained in the video. Completely different concepts and principles.

Science is ever evolving and the only way to prove something is to test it through the measures we currently understand. If i discovered a new type of “mile” or “yard” to describe a distance, i would still have to use miles and yards in order to prove that this new type of distance exists.

[@derpy_blue]

recently a new study has been released that stated the age of the universe to be twice as big - 27 billion years

[@GTRNights]

Yep, the issue is that because it's expanding, and increasing in the rate of expansion. We can only detect what we're able to detect due to the limitations of light speed in a vacuum. Outside of what we can see, it could be even way older. That's why it's so confusing that JWST found fully mature and developed galaxies at the absolute maximum redshift. It has to be older than we currently think and JWST is going to really help us move forward with our understanding. Science is amazing because it's the best method humans have devised thus far for discovering truth.

The same is not true for dark matter and dark energy at all... Not at all. Dark matter and dark energy are 2 separate ad hoc additions that are used to make a model that is made to fit the data.

[@Acat253]

They don’t know what they’re talking about ! The universe is 46.5 trillion years old. Read the Billy Meier material to find out why it’s 46.5 trillion years old !

[@egay86292]

these models change all the time. they are anything but "consistent."

[@garyphillips3552]

God finds a way.

[@aaron0077]

God's not real. When you die your consciousness will cease to exist until the end of time and your body will turn to nothing but wormfood 🪱🪱🪱 and eventually even your BONES will disintegrate. Hope this helps bud 😀

[@timclark9963]

OMG. Always has to be at least one

[@shadenym5094]

Your model is true if it explains everything not if it explains most things lol

[@corsair371]

The sun ☀️ is a small star So billions of years old doesn’t make sense

[@tombignell8932]

Even a small star lasts billions of years, it's difficult to comprehend but the evidence checks out, the recent discovery of a galaxy older than expected puts doubt on the accuracy of the age of the universe but it doesn't change how old our sun or other stars are and how accurate our method of determining it is

[@GTRNights]

Our star is a G-type main-sequence star. These types generally have lifespans of about 10 billion years. Ours is 4.6 billion years old and won't start running out of hydrogen fuel for about another 5 billion - becoming a red giant, and then eventually a white dwarf. Are you saying it should already be starting to enter its red giant phase, or are you just generally ignorant about how long G-type stars live overall? Was it supposed to die already? Like I'm literally having a hard time processing what it is you're even suggesting, so it's difficult to give you an answer. It seems like you should study up on the absolute basics of the basics if this stuff confuses you. My youngest boy knew this stuff by age 6.
