hello mortals the phrase the universe is weird is perhaps the most overused qualifier when talking about the cosmos and when the weirdest part of the average day of a human are things like wondering where half of the cake from the fridge disappeared or why didn't you succeed even if you tried your best it's easy to forget that you are actually part of the same huge universe with black holes and quantum physics which are not limited to science documentaries that is why we shall go over some anomalies in the universe that should give you a perspective of how boring all our lives are thanks to wandriam for sponsoring this video the age of the universe is roughly NUMBER_TOKEN billion years scientists have conducted countless calculations regarding it so unless our current understanding of cosmology and of the big bang theory is completely off we can be pretty confident in this number that is until scientists stumbled upon the methuselah star located in the libra constellation after making the measurements they arrived at an age NUMBER_TOKEN million years older than that of the universe what did the star attain the secret of immortality from the queen which allowed them both to exist before the universe itself or did we screw up some measurements guiding ourselves by the occam's razor the simplest explanation is probably the right one after analyzing the spectral range of the star it has been found that it contains a substantially lower metal content than the sun meaning that at the time of its birth there weren't many heavy elements in the universe some recent subsequent studies revised its age to NUMBER_TOKEN billion years just at the start of the universe but also with an error margin that would allow it to be one of the first stars to form in the observable universe at least that we know of or it's an actual lovecraftian deity that transcends time and space moving on now let us take a look at the big things the observable universe has a radius of NUMBER_TOKEN billion light years meaning that it has been expanding at the speed of light for the past NUMBER_TOKEN billion years since the big bang except that the big bang happened NUMBER_TOKEN billion years ago what does that mean did the universe exceed its own cosmic speed limit actually yes and it's called inflation during the inflationary epoch which lasted a very long period of NUMBER_TOKEN to the power of minus NUMBER_TOKEN seconds the universe expanded the scale of one nanometer to more than NUMBER_TOKEN light years that's millions of times faster than the speed of light so why didn't einstein commit seppuku because nothing actually travels past the speed of light it's the fabric of space-time itself that expands so nothing is violated you can go back to sleep einstein pardon the side track for a long time the biggest structure inside the observable universe used to be the sloan great wall at NUMBER_TOKEN billion light years in length which is a filament composed of hundreds of galaxies that was until NUMBER_TOKEN when scientists discovered the enormous hercules corona borealis great wall seven times larger than that at NUMBER_TOKEN billion light years in length it was mapped using NUMBER_TOKEN gamma-ray bursts which are the most energetic events known to occur in the universe this structure seems all good and nice until you take into account the cosmological principle it claims that the universe is homogeneous on large enough scales so if you zoom out really really far out any two patches of the universe should look similar except the great wall is eight times bigger than this limit it even seems to be too big to be able
