The researchers say the galaxies are so massive, they are "in tension with 99 percent of the models for cosmology." This means that either the models need to be altered, or scientific understanding of galaxy formation requires a fundamental rethink. ![]() By using the James Webb Space Telescope (JWST) to peer roughly 13.5 billion years into the past, the astronomers found that enormous galaxies had already burst into life very quickly after the Big Bang, when the universe was just 3% of its current age. Currently accepted theories suggest that 1 to 2 billion years into the universe's life, these early protogalaxies reached adolescence - forming into dwarf galaxies that began devouring each other to grow into ones like our own.īecause light travels at a fixed speed through the vacuum of space, the deeper we look into the universe, the more remote light we intercept and the further back in time we see. Scientists don't know exactly when the first clumps of stars began to merge into the beginnings of the galaxies we see today, but cosmologists previously estimated that the process began slowly taking shape within the first few hundred million years after the Big Bang. ![]()
