Scientists reveal how did dark matter create the Universe’s first stars?

Scientists propose dark stars illuminated the universe’s earliest era. Theory suggests dark matter powered stars before normal fusion ignited. They formed within first hundred million years after Big Bang. Dense gas clouds met concentrated dark matter haloes gravitationally.

Dark matter particles may annihilate, releasing heat inside protostars. This energy halted collapse, preventing nuclear fusion from starting. Resulting objects grew enormous, luminous and yet relatively cool surfaced.

Unlike normal stars, dark stars lacked fusion-driven cores entirely. Models predict masses thousands or millions of times our Sun. Their cooler temperatures shifted light into infrared wavelengths detectable today.

Astronomers use James Webb Space Telescope to hunt candidates. Some distant bright objects defy explanation as galaxies or stars. These sources match predictions for massive dark star profiles. Yet researchers caution evidence remains uncertain and debated strongly.

Dark stars could explain rapid emergence of early supermassive black holes. When dark matter fuel ended, stars may collapse directly. Such collapse could seed black holes seen surprisingly early. Confirmation would reveal dark matter behaviour beyond gravity alone.

Further Webb observations will test theoretical predictions carefully. Advanced simulations will refine expected brightness and spectra signatures. Many dark stars may become unusual galaxies upon closer study. The scientists focus on extraordinary claims require extraordinary supporting evidence.

Dark stars link invisible matter with first sources of light. They challenge assumptions about how earliest stars truly formed. Ongoing research may rewrite the universe’s opening stellar chapter. If proven, darkness once helped the cosmos shine brightly.
