Our galaxy is approximately 100,000 light-years from edge to edge. It would take longer than the age of the entire universe for us to launch a camera outside the galaxy far enough to take the image; it would then take many millennia for the radio waves to travel back to us with the ...
根据文章第二段“The Hubble Space Telescope (HST) was the record holder for the farthest visible distance in space until the launch of the James Webb Space Telescope (JWST) in 2021.(在2021年詹姆斯·韦伯太空望远镜(JWST)发射之前,哈勃太空望远镜(HST)一直是太空最远可见距离的纪录保持者。)”及“...
even in principle. That domain is definitely finite. That’s essentially because, like on the ocean,there’s a horizonthat we can’t see beyond. And just as we don’t think the ocean stops just beyond our horizon, we expect galaxies beyond the limit of our observable univ...
The short answer: we don’t know. But what we do know is that dark energy is real, it’s driving the universe’s accelerated expansion, and it makes up about 68-70% of everything in existence. The history of the universe is outlined in this infographic. Credit: NASA A Brief History ...
Why is there far more matter than antimatter in the observable universe?Question:Why is there far more matter than antimatter in the observable universe?Matter:A matter is defined as the substance which contains mass, and it occupies some space when placed in any container. The atoms...
googolplex is an extremely large number, equal to 10 raised to the power of a googol. a googol is 1 followed by 100 zeros. so, googolplex is 10^(10^100). it is an unimaginably huge number that surpasses the total number of particles in the observable universe. what is the difference...
telescope, which will beequipped with the world's largest digital camera, will let researchers peer farther into the solar system than any of its predecessors allowed, similar to how theJames Webb Space Telescopehas enabled researchers to look farther across the observable universe than ever be...
milliseconds to coordinate in real time the stimuli produced by the sensory organs and the actions to activate the motor organs. The performance of these functions is distributed in the brain and involves multiple neural structures, such as the basal ganglia, cerebellum, hippocampus and cerebral ...
So, somewhat speculatively, we suggest we live inside a gigantic quantum gravity computer known as the Hubble sphere, and we even are quantum gravity computers. The observable universe is based on this model, basically a quantum gravity computer that calculates approximately 10104 bits per second (...
A Googol is already bigger than the number of elementary particles in the known Universe, but then there is the Googolplex. It is 1 followed by Googol zeros. I can't even write down the number, because there is not enough matter in the observable universe to form all the zeros:...
