Stars need enough mass to die violently. If a star is over 8 Suns heavy, it can supernova. Its core makes iron, which can’t fuse, so it collapses. The collapse triggers a massive explosion. Smaller stars (like the Sun) just fade into white dwarfs. But a white dwarf can still explode if it eats too…

First of all, anti-matter and dark matter are totally separate things, so don’t get confused between the two. Anti-matter particles were formed right after the big bang along with normal matter particles, and they are just the opposite of normal matter particles. Photons converted into matter-antimatter pairs, which annihilated again to form photons in the…

Different Scientists have different answers, but the general one is- we don’t know. Albert Einstein said that before the big bang, there wasn’t time itself, so how could things possibly be placed in a chronological order without the fourth dimension- time? This is the most believed explanation of your question but humans don’t have much…

Yes, the universe is expanding — a discovery first made in 1929 by Edwin Hubble, who observed that distant galaxies are moving away from us, with more distant ones receding faster. This expansion is not due to galaxies moving through space, but because space itself is stretching, like dots on an inflating balloon. The light…

This might not come as a surprise, but yeah let’s be true, it’s Mars. Mars Has its own pros and cons for survival, here’s the list: PROS: 1) Similarity In Rotation Period: A day on Mars is just 37 mins longer than a day on Earth. 2) Similarity in Axial Tilt: mars is tilted 25…

Sunlight and the Spectrum Sunlight, or white light, is composed of a spectrum of colors, often remembered by the acronym VIBGYOR: V: Violet I: Indigo B: Blue G: Green Y: Yellow O: Orange R: Red Each of these colors corresponds to light waves of different wavelengths, with violet and blue light having shorter wavelengths and…
