Physicist: Probably nothing. We do know that the universe doesn’tneedanything to expand into, and we haven’t seen any evidence that there is anything outside of the universe. But there has still been some speculation. In the last hundred years physics has gotten pretty weird, and...
Come on, admit it, you’ve had this question. “Since astronomers know that the Universe is expanding, what’s it expanding into? What’s outside of the Universe?” Ask any astronomer and you’ll get an unsatisfying answer. We give you the same unsatisfying answer, but really explain it...
If still you don’t know that we live in an expanding Universe, then I’m clearly not doing my job. And so once more, with feeling… the Universe is expanding. But that certainly doesn’t answer all the questions that go along with the it. Remove All Ads on Universe Today Join our ...
The cosmological horizon is caused by the expansion of the universe. You can picture this as being like ants crawling on a balloon. As the balloon expands only ants that are close to each other will be able to run into each other; more distant ants can crawl at each other at full spee...
But, for all of it, the Universe isstill expanding. What's amazing is, despite all of the things that could cause this expansion, there's onlyonething that the expansion rate depends on. Know what it is? Theenergy densityof the Universe. Or, in other words, the total amount of matter...
The universe is about 13.8 billion years old. It came into existence during the big bang. Due to the speed of light, telescopes can only see up to 13.8 billion light-years away. The universe is still expanding. There is debate among scientists whether the universe is infinite or is finite...
Webb is known for its ability to stare unblinking into the deep sky. Since it came online, it has produced deep-field images containing thousands of distinguishable galaxies and narrow profiles of individual stars—and its repertoire is still expanding. In June 2024, JWST astronomers presented the...
In the 1920s, astronomers like Edwin Hubble noticed that the Crab Nebula was getting bigger in photos of the night sky. Hubble did the math and realized that the universe was expanding at a meaningful fraction of the speed of light. ...
Hello, I want to calculate the average number of 7 numbers that I tracked for each day of a week. In the next row there should be the average of the...
Open Innovationis a form of collaboration that aims to bring together diverse stakeholders and build new solutions for problems by expanding the traditional boundaries between business sectors.
