In a world full of fascinating facts and practical queries, certain topics capture widespread interest. From basic science principles to budget travel tips and cricket governance, these subjects offer insights into everyday wonders and real-world decisions. This article dives deep into three popular search keywords: why sound cannot travel through a vacuum, the cheapest country to travel from India in 2026, and the latest on BCCI restrictions affecting stars like Virat Kohli and Jasprit Bumrah. Updated with the most recent information as of early 2026, we’ll explore the science, economics, and sports policies shaping these discussions.
Whether you’re a student curious about physics, a traveler planning an affordable getaway, or a cricket fan following player regulations, this guide provides comprehensive, up-to-date details to inform and inspire.
Why Sound Cannot Travel Through a Vacuum
Sound is a mechanical wave that relies on vibrations to propagate. It requires a medium—such as air, water, or solids—for particles to collide and transfer energy. In a vacuum, like outer space, there are no particles to vibrate, making sound transmission impossible under normal conditions.
This fundamental principle explains the famous tagline from the movie Alien: “In space, no one can hear you scream.” Without air molecules or any matter, sound waves have nothing to push against, resulting in complete silence. Experiments in vacuum chambers demonstrate this vividly—alarms or bells become inaudible as air is pumped out, proving the need for a medium.
Sound travels fastest in solids (due to closely packed particles), slower in liquids, and slowest in gases like air (about 343 m/s at room temperature). In space, the near-perfect vacuum means no propagation at all. While recent research has shown “acoustic tunneling” across tiny gaps in controlled lab settings (where sound jumps between objects separated by less than the wavelength), this doesn’t apply to vast cosmic vacuums. Everyday understanding remains: sound cannot travel through empty space.
This concept ties into broader physics education, highlighting differences between mechanical waves (like sound) and electromagnetic waves (like light or radio), which can travel through vacuums. It’s a staple in school curricula and explains why space is eerily quiet despite cosmic events.

Cheapest Countries to Travel from India in 2026
With rising travel enthusiasm among Indians, finding budget-friendly international destinations remains a top priority. In 2026, several countries offer exceptional value, with low flight costs, affordable accommodations, cheap food, and easy visa access. Factors like visa-free entry, proximity, and currency exchange make these spots ideal for trips under ₹50,000–₹1,00,000 for a week.
Nepal tops many lists as the absolute cheapest country to travel from India. Visa-free for Indians, short flights (often under ₹5,000–₹10,000 round-trip from major cities), and daily costs as low as ₹1,500–₹3,000 make it unbeatable. Explore Kathmandu’s temples, trek in Pokhara, or enjoy Himalayan views without breaking the bank.
Thailand follows closely, with visa-free entry up to 60 days and dropping flight prices (Phuket routes down 13%). Street food, beaches, and temples cost little, with budgets around ₹40,000–₹60,000 for a week.
Vietnam shines for all-round affordability—₹50,000–₹70,000 trips cover Hanoi, Halong Bay, and Ho Chi Minh City. Low daily expenses (food under ₹500, hostels ₹1,000) and scenic beauty draw backpackers.
Other strong contenders include:
- Sri Lanka: Visa-free, beaches, and wildlife for similar budgets.
- Indonesia (Bali): Affordable flights and stays.
- Malaysia: Dropping flight prices and diverse attractions.
- Bhutan: Entry permit-based, but low costs for nature lovers.
- Cambodia and Laos: Hidden gems with minimal expenses.
Tips for budget travel: Book flights early via apps, opt for hostels or homestays, eat local street food, and use public transport. Shoulder seasons (avoiding peak holidays) save more. These destinations combine culture, adventure, and relaxation without high costs.

BCCI Restrictions on Virat Kohli and Jasprit Bumrah Travel
The Board of Control for Cricket in India (BCCI) maintains strict policies on player workload, travel, and participation to prioritize national duties and health. In 2026, these rules impact stars like Virat Kohli and Jasprit Bumrah significantly.
Recent central contracts for 2025-26 (October 2025–September 2026) place Bumrah in the top Grade A alongside Shubman Gill and Ravindra Jadeja. Kohli, now focusing only on ODIs after retiring from Tests and T20Is, is in Grade B with Rohit Sharma. This reflects format participation and performance.
BCCI bans contracted players from overseas T20 leagues unless retired from internationals. IPL Chairman Arun Dhumal confirmed no exceptions for Kohli, Bumrah, or others—workload management is key. Bumrah, as India’s premier pacer, needs rest after intense series.
Travel restrictions tightened post-2024-25 losses: Players must travel with the team (no separate family flights), families limited to two weeks on long tours (45+ days), and no personal staff (cooks, security) allowed. Kohli’s past separate travel with family is curtailed; Bumrah followed similar patterns earlier.
These aim to foster team unity, control costs, and manage fatigue amid packed calendars. Domestic commitments like Ranji Trophy remain mandatory.
