@ExploreCosmos_ Why is the common belief of the universe only shooting out in one direction, in this picture out to the right, wouldn't common sense explain that after the big bang the universe would explode out in 360 degrees?

When we say the universe is expanding, they’re not speaking metaphorically. Space itself is stretching, and galaxies are drifting apart as a result. The rate at which this happens is encoded in a number known as the Hubble constant. In principle, it should be a single, well-defined value. In practice, it isn’t. And that’s where things get interesting. There are two fundamentally different ways to measure how fast the universe is expanding. One looks at the early universe, using the cosmic microwave background, the faint afterglow of the Big Bang. The Planck satellite mapped tiny fluctuations in this radiation with extraordinary precision. From that snapshot of the universe when it was just 380,000 years old, cosmologists can infer how fast it should be expanding today. This method gives a lower value. The other approach looks at the local universe, what’s happening much closer to us in cosmic terms. By measuring distances to nearby galaxies using standard candles like supernovae, and calibrating them with observations from telescopes such as the Hubble Space Telescope and the James Webb Space Telescope, we can directly estimate the current expansion rate. This method consistently gives a higher value. The problem is not that these measurements are slightly off. It’s that they disagree by more than they should, at roughly the 5σ level, well beyond what we expect from statistical uncertainty. This discrepancy is known as the Hubble tension, and it has become one of the most persistent and uncomfortable puzzles in modern cosmology. At first, many assumed it would go away. Maybe there were subtle calibration errors. Maybe some systematic bias hadn’t been accounted for. But as the data improved, the tension didn’t shrink. It became sharper. So now the question has shifted. Not “where’s the mistake?” but “what are we missing?” One possibility is that there are still hidden systematics in one or both methods. Measuring cosmic distances is notoriously difficult, and even small biases can ripple outward into large discrepancies. But the fact that independent teams, using different techniques, keep finding similar results makes this explanation harder to sustain on its own. The more intriguing possibility is that the standard model of cosmology—ΛCDM—might be incomplete. That model has been extraordinarily successful. It explains the large-scale structure of the universe, the distribution of galaxies, and the detailed patterns in the cosmic microwave background with remarkable accuracy. But it also relies on components we don’t fully understand, like dark matter and dark energy. If the Hubble tension is real, it could be hinting at new physics. Perhaps dark energy evolves over time instead of being constant. Perhaps there were additional relativistic particles, like unknown neutrino species, in the early universe. Or perhaps gravity itself behaves slightly differently on cosmological scales than we currently assume. None of these ideas are confirmed. But they are being taken seriously, because the alternative, that all these independent measurements are wrong in just the right way, is becoming increasingly unlikely. There’s also something deeper at play here. The two methods are not just different techniques, they are probing different epochs of the universe. One looks back to the very beginning, the other measures the present. The fact that they don’t agree may be telling us that the story of cosmic expansion is more complex than a single, smooth evolution. So which one is right? At the moment, we don’t know. And that’s precisely why this tension matters. Because when the universe gives you two answers to the same question, it’s usually not confused. It’s trying to tell you something.

@RightPulseNewss Big neg

Would you like to have Obama back for another Presidential term? Be honest A. YES B. NO Everyone better answer this one correctly👆👀!!

Pale Blue Dot is a photo of Earth that was taken by the Voyager 1 space probe in 1990 from a distance of about 6 billion kilometers (3.7 billion miles) as it was leaving our solar system. This is what Carl Sagan said about the photo: "Look again at that dot. That's here. That's home. That's us. On it, everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor, and explorer, every teacher of morals, every corrupt politician, every 'superstar,' every 'supreme leader,' every saint and sinner in the history of our species lived there — on a mote of dust suspended in a sunbeam. The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand. It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known.”

@realDonaldTrump the ridiculous haters will soon have no place or better yet, get their heads out of their asses & realize our movement is not directed by hate but by common sense for the good of humanity

There's definitely a shift happening because of u, sir, you started it and shine brighter than others; by the grace of God "some politicians" may finally be getting real and not appeasing the status quo. Enough with status quo! Real Change!! Thank YOU

The thing I'm most concerned about is what happens after your term? If we go back to politics as usual it would be a tragedy for all. If you're human and have common sense you'll realize at some point what's happening is long overdue. Thank you President Trump God Speed Sir.

@realDonaldTrump MR. PRESIDENT, SIR. I just want to acknowledge that I feel you & your administration are leading with common sense & I am a big big fan. Good, bad, or indifferent your direction is commendable. It's about time to do what all previous POTUS's wouldn't.

@elonmusk Elon, why does it appear that the infrastructure in China is surpassing the infrastructure in the USA? It appears their engineering techniques are quite literally shitting on ours. What we need is to focus more on multiple companies collaborating on projects & far less red tape

Starship can reach Mars in 6 months every 26 months when the planets align

@AOC I'm curious: Would you, AOC, be willing to share with your constituents what your net worth is currently, including proof such as your Financials?

The cynics will tell you that one vote won’t change anything. But what they don’t tell you is that nothing can change without a vote. The truth is, the world doesn’t belong to the cynics. It’s up to us. New York: It’s time to vote.🗳️ Tuesday, June 25th. Spread the word.

@BGatesIsaPyscho I get it's not the best practice to be eating on a public bus, but it is her perogative to do so. The dude who's fasting should've kept to himself and mind your own business unless someone is getting abused or appears to be on the verge of getting abused.

🇬🇧 On a British Bus somewhere “Please stop eating - I’m fasting for Ramadan” “I’m eating my lunch - that’s you’re problem” Dude fasting for Ramadan isn’t happy he can smell this Woman’s food - who’s in the right here?

@FFlowzzzz 💯 Spot on.... men are easy to please. If you truly LOVE him, respect him. Respect her as well no question... women are way more complicated than men, that's a biological fact, women, you know this truth. Men only want/need to feel special to the woman above everything else.

Maybe now that Dr. Arinze, a successful medical doctor in Canada who talked about Japa the other time, is saying the same thing about marriage and relationships abroad. Maybe you all will listen.... Anyways, in life, you either learn or Perish!! Ekwusigom ✌️

@thehill what I'd like to see is something even more, say, drastic, and listen/hear/ELECT those who have been scared/"blackballed" by the "old" way of thinking and doing things... to Power who have a way better understand and actual fabric of the PEOPLE of the USA as a whole

@thehill what's happening is the generational shift that's been well overdue...

@thehill if the Dems want to keep with the times/transition/shift they need to find their person/politician to do the same. It's apparent that they are struggling to do so. The AOC's/Omars/Pelosi's aren't it. Happy hunting Dems

@thehill President Trump is a necessary transitional person/ politician. He's old enough and hip enough to be the guy/politician to usher in the new out with the old

@thehill someone is intelligent and understands what the psychology of the majority is of those who are taking or have taken the torch want in media and conversation The Hill is the media of the present and near future

@elonmusk I would abolish the Democrat and Republican parties. Everyone should be Independent. All those 2 parties do is divide the people and the country. The Divided States of America.

This is a good question. What would you do?

@JDVanceNewsX Polosi and every other wealthy politician who acquired their wealth during their political career should have to contribute a minimum of 37% of their wealth to the deficit

🚨BREAKING: Nancy Pelosi’s annual salary is $174,000. Her estimated net worth is $240 MILLION. Should DOGE investigate? YES or NO? If Yes, Give me a THUMBS-UP👍!

@elonmusk Every politician who has over $1m that was acquired during their political career should have to contribute 37% of their wealth to the deficit.

The Biden administration launched a massive multi-year lawsuit against SpaceX for not hiring asylum seekers, despite the fact that SpaceX is legally BARRED from hiring non-permanent residents under ITAR, because rockets are an advanced weapons technology. In other words, it was both illegal to hire asylum seekers and illegal not to hire asylum seekers!! An insane case of lawfare against @SpaceX.
