Hubble Telescope Tracks Dwarf Galaxy Stars to Map Dark Matter

The Draco dwarf is a faint, star-poor but dark-matter rich galaxy. Here we see Hubble zooming in on some of its stars.

The Hubble Space Telescope has shown that dark matter is concentrated in the core of a nearby dwarf galaxy, a discovery that comes to the aid of the Standard Model of Earth. cosmology. This model basically predicts that dark matter is “cold,” but recent findings seem to indicate that the substance is “warm.” However, these … Read more

What happens when matter is squeezed to the brink of collapse? We weighed a neutron star to help NASA find out

Neutron stars are among the most extreme objects in the universe. Formed from the collapsed cores of supergiant stars, they weigh more than our sun and yet are compressed into a sphere the size of a city. The dense cores of these exotic stars contain matter compressed into unique states that are impossible for us … Read more

We need to consider alternatives to dark matter that better explain cosmological observations

Do the constants of nature — the numbers that govern how things behave, like the speed of light — change over time as the universe expands? Does light get a little tired of traveling vast cosmic distances? Dark matter and dark energy were once thought to explain these cosmological phenomena, but recent research suggests that … Read more

Dark matter may consist of particles that travel faster than the speed of light

Have you ever wondered what the secrets of the universe are? Dark matter, dark energy, particles moving at lightning speed – these are the central focuses of recent cosmic mysteries. Imagine sharing our universe with particles that travel faster than light, known as tachyons. This is the bold new theory presented by scientists Samuel H. … Read more

Dyson spheres: the key to the missing matter in the universe?

Dyson Spheres The Key To The Universe’s Missing Matter

Recent studies have led to renewed interest in the concept of Dyson spheres, theoretical megastructures that could potentially harness the energy of entire stars. This intriguing idea has led some scientists to speculate whether such structures could explain the universe’s missing mass. Despite the excitement, many experts remain skeptical about the existence of Dyson spheres … Read more

Scientists use two new quantum methods to catch dark matter suspects

The hunt for dark matter is about to get a lot cooler. Scientists are developing supercold quantum technology to hunt for the universe’s most elusive and mysterious matter, which currently poses one of science’s greatest mysteries. Despite the fact that dark matter outnumbers the amount of ordinary matter in our universe by about six times, … Read more

Why the French election results matter more to financial markets than the British vote

Forget the British general election. The poll that financial markets will be watching most closely in the coming days is the second round of parliamentary elections in France this Sunday. The French poll is unpredictable, to say the least. The first round of voting The prospect of a stalemate in parliament was already raised last … Read more

Searching for dark matter with the coldest quantum detectors in the world

The experiment takes place at about one 10,000th of a degree above absolute zero in a special refrigerator; Dr Autti (right). Credit: Lancaster University One of science’s greatest mysteries may be one step closer to being solved. About 80% of the matter in the universe is dark, meaning it can’t be seen. In fact, dark … Read more

Ultra-precise atomic clock doubles previous accuracy, could detect dark matter

Time: It bends and curves, or appears to speed up or slow down, depending on your position or perception. So precisely measuring its passage is one of the most fundamental tasks in physics—and could help us land on Mars or even observe dark matter. Now, physicists from the US National Institute of Standards and Technology … Read more
