Q & A - Space Mysteries Scientists Still Can't Explain in 2025
This Parent Q&A sheet for Space Mysteries Scientists Still Can’t Explain in 2025 is designed to help parents and carers support learning during home education. The topic covers fascinating unanswered questions about the universe, such as black holes, dark matter, fast radio bursts, and the mystery of missing antimatter. These are real puzzles that scientists are still trying to solve, and they offer excellent opportunities for critical thinking and creative discussion.
The questions on this page reflect the kinds of things children might ask during or after a lesson on the topic. Each answer is written clearly and simply, with enough detail to help parents respond confidently—even if science isn’t their strongest subject. You don’t need to know all the answers yourself to guide your child effectively, and this resource is here to help.
Whether you’re using this topic as part of a wider science project or a one-off exploration, the Q&A sheet gives you everything you need to have meaningful conversations, ask deeper questions, and spark your child’s curiosity. It works well alongside the learning resource and lesson plan on Lenara.uk, and it’s flexible enough to use at your own pace.

|---|---|
| Tip for Parents | This Q&A sheet helps you feel more confident when discussing complex science topics with your child. Use these answers as a guide to help explain tricky ideas in simple, friendly language. Encourage your child to ask more questions, and use these answers as conversation starters. |
| 1. What do scientists mean by a “space mystery”? | A space mystery is something in the universe that scientists have observed but don’t fully understand yet. It could be a strange object, an unexpected behaviour, or a missing piece in a scientific theory. |
| 2. What is antimatter, and why is it missing? | Antimatter is the opposite of regular matter—each particle has the opposite charge. At the Big Bang, matter and antimatter should have been created in equal amounts. But today, we see almost no antimatter in the universe, and scientists don’t know why. |
| 3. What are fast radio bursts? | Fast radio bursts (FRBs) are extremely short but powerful signals of radio waves coming from far away in space. Some only happen once, while others repeat. Their cause is still unknown, although some theories suggest they come from collapsing stars or magnetars (super-magnetic neutron stars). |
| 4. What is dark matter? | Dark matter is invisible material that doesn’t give off light or energy, but we know it exists because of how it affects gravity. It helps hold galaxies together. However, scientists still don’t know what it’s made of. |
| 5. How do we know dark matter is real if we can’t see it? | We can measure the way galaxies move and notice that there isn’t enough visible matter to explain the speed they spin. The extra gravity needed must come from something invisible—that’s what we call dark matter. |
| 6. What is dark energy? | Dark energy is a mysterious force that seems to be making the universe expand faster over time. It’s even more mysterious than dark matter, and we don’t yet know what it actually is. |
| 7. Why are black holes still puzzling? | Black holes have such strong gravity that not even light can escape. We still don’t fully understand what happens at the centre or how they interact with time, space, and information. The physics inside a black hole might be completely different from what we know. |
| 8. What happens to things that fall into a black hole? | They seem to disappear forever, but this breaks the rules of physics, which say that information can’t be lost. This creates a puzzle called the “information paradox.” Scientists are still debating what really happens. |
| 9. What is Planet Nine, and has it been found? | Planet Nine is a possible giant planet thought to exist far beyond Pluto. Some distant objects in our solar system have strange orbits that could be caused by a hidden planet. But no one has seen it yet. |
| 10. What are Lyman-alpha blobs? | These are huge clouds of gas that glow in the early universe. They are bigger than galaxies, and we’re still not sure what causes their glow. They might be linked to galaxy formation, but it’s still being studied. |
| 11. Why do some scientists think aliens might exist? | With billions of galaxies and even more planets, it seems possible that life might exist elsewhere. Some planets seem to have the right conditions, and scientists keep searching for signs like water, oxygen, or unusual signals. |
| 12. What’s the Fermi Paradox? | This is the question: “If aliens exist, why haven’t we found them yet?” With so many planets, it seems we should have seen signs of life—but we haven’t. The answer could lie in distance, time, or other unknown factors. |
| 13. What do telescopes like the James Webb do? | They collect light from far away and let us see galaxies, stars, and planets in great detail. The James Webb Telescope can even look at the atmospheres of distant planets to check for signs of life. |
| 14. Why is space science full of mysteries? | Because space is so vast and our tools, while powerful, are still limited. The more we discover, the more new questions we have. Mystery is a natural part of learning in science. |
| 15. How do scientists try to solve space mysteries? | They use telescopes, satellites, computer models, and lab experiments. They collect data, test ideas, and publish results for others to check. This process helps build knowledge over time. |
| 16. Why do mysteries matter in science? | Mysteries drive research forward. They make scientists curious and help us discover new things. Every solved mystery usually leads to more questions and deeper understanding. |
| 17. What can I do if my child asks a question I can’t answer? | That’s okay! Say, “Let’s find out together.” Look things up in the article or online using trusted science websites. Learning together can be just as valuable as knowing all the answers. |
| 18. How can I explain “gravity” in a simple way? | Gravity is a force that pulls things together. It’s what keeps us on Earth and makes the Moon orbit us. Bigger things, like planets and stars, have stronger gravity. |
| 19. What is the most important takeaway from this topic? | That science is about asking questions. We don’t know everything—and that’s okay. Wondering, exploring, and learning more is what science is all about. |
| 20. What if my child wants to learn more about this? | That’s brilliant! You could explore more articles on space, check out science videos, download space apps, or even visit a local science centre or observatory. Encourage their interest—they might become the next space explorer or scientist! |
